Western medical research has shown that Medical Qigong has profound beneficial effects for cancer patients. For example, Impact of Medical Qigong on quality of life, fatigue, mood and inflammation in cancer patients: a randomized controlled trial reports on the positive results for the role of Medical Qigong in improving Quality of Life (QOL), immune function, mood and fatigue parameters, reducing inflammation and improving survival in cancer patients.
A Review of Qigong Therapy for Cancer Treatment provides an overview of research results on Qigong for cancer. Studies on Qigong and its curative effect on cancer have demonstrated consistent results for its inhibitory effect on cancer growth and metastasis, in both in vitro and in vivo studies, as well as in clinical observation. It is possible to reach a general conclusion that Qigong therapy for cancer treatment may be a powerful alternative to what we are using today in treating cancer.

New cancer study finds benefit in old therapy. Patients who practiced medical Qigong experienced significant improvements in quality of life, including greater physical, functional, social and emotional wellbeing, and enhanced cognitive functioning, while the control group deteriorated in all of these areas.
Mind-body practices in cancer care. Being diagnosed with a life-threatening disease such as cancer and undergoing treatment can cause unwanted distress and interferes with quality of life. Uncontrolled stress can have a negative effect on a number of biological systems and processes leading to negative health outcomes. While some distress is normal, it is not benign and must be addressed, as failure to do so may compromise health and QOL outcomes. We present the evidence for the role of stress in cancer biology and mechanisms demonstrating how distress is associated with worse clinical outcomes. The National Comprehensive Cancer Network states that all patients be screened with the single-item distress thermometer and to also indicate the source of distress and to get appropriate referral. In addition to the many conventional approaches for managing distress from the fields of psychology and psychiatry, many patients are seeking strategies to manage their distress that are outside conventional medicine such as mind-body techniques. Mind-body techniques such as meditation, yoga, tai chi, and qigong have been found to lower distress and lead to improvements in different aspects of quality of life. It is essential that the standard of care in oncology include distress screening and the delivery of different techniques to help patients manage the psychosocial challenges of diagnosis and treatment of cancer.

Acupuncture benefits breast cancer survivors. Researchers at Penn Medicine and other institutions found that electro-acupuncture (“real” acupuncture) helped reduce joint pain by as much as 40 percent in women with breast cancer, whether the patient expected it to work or not. The study also found that “sham” acupuncture – which involves nonpenetrative needles and no electrical stimulation – provided pain reduction as high as 80 percent if patients had a high degree of expectation that it would work.
The study results provide important implications for future treatment of breast cancer patients with joint pain. Patients who reported pain relief had increased expectancy that it would continue to work over the course of their acupuncture treatment as compared with nonresponders, suggesting that positive responses during the process of real acupuncture increased the expectations of further positive outcomes.
“These findings certainly challenge the notion held by some that acupuncture is ‘all placebo,’” said the study’s lead author Joshua Bauml, MD, an assistant professor of Medicine in the Abramson Cancer Center. “If it were ‘all placebo,’ patients receiving real acupuncture who had low expectations that it would work would report little or no reductions in pain. But that’s not the case.” Sham acupuncture only produced clinically important pain reduction for those with high onset expectancy. But patients with the highest expectation that it would work reported as much as 80 percent reductions in pain – twice the rate of patients receiving real acupuncture. Sham acupuncture patients with low baseline expectancy scores did not report any significant pain reduction.
Harvard Medical School review presents the latest available evidence regarding the use of acupuncture for cancer pain. Cancer pain is one of most prevalent symptoms in patients with cancer. The National Comprehensive Cancer Network guidelines for adult cancer pain recommends acupuncture, as one of several integrative interventions, in conjunction with pharmacologic intervention as needed. It also provides "actionable" acupuncture protocols for specific cancer pain conditions and related symptoms in order to provide more clinically relevant solutions for clinicians and cancer patients with pain.

Do spiritual patients want spiritual interventions? A qualitative exploration of underserved cancer patients' perspectives on religion and spirituality. Spirituality plays a central role in the cancer experience of this underserved ethnically-diverse population. While spirituality seems to be a universal concern in advanced cancer patients, the meaning of spirituality differs across individuals, with some equating it with organized religion and others taking a more individualized approach. It is important that psychosocial interventions are developed to address this concern. Future research is needed to further explore the different ways that patients conceptualize spirituality and to develop spiritually-based treatments that are not "one size fits all."
Master Helen Liang and “Qigong for Cancer”. Clinically proven, Qigong can help cancer patients to deal with various side effects from cancer treatments. In China, studies even show how Qigong treats cancer. Master Helen Liang claims that she is not a medical doctor but she wants to share her knowledge with anyone who is combating cancer or trying to prevent being a cancer victim. There are three primary points of Helen’s Qigong Methodology: 1. Learning how to oxygenate the entire body at a cellular level; 2. Relieving Qi stagnation from the body at a cellular level; 3. Increasing blood and oxygen circulation without “burning” energy. Through a series of gentle exercises and simple stretches along with deep breathing, it can increase cancer recovery, boost the immune system, reduce pain, and improve sleep quality.
Growing Young: 6 Powerful Exercises for Initiating DNA Repair and Cellular Rejuvenation. "Researchers found that the DNA repair rate of people with cancer in remission compared to healthy people was much slower. The patients in remission were then taught qigong stress-reducing techniques. Following three months of practice, their cell repair rate had nearly doubled. It is conceivable that the “new” energy medicines of qigong and vibrational sound can affect the erratic energy of DNA and stimulate cellular rejuvenation."

Qigong in Cancer Care: Theory, Evidence-Base, and Practice. Regular practice of Qigong exercise therapy has the potential to improve cancer-related QOL and is indirectly linked to cancer prevention and survival. Wide-spread access to quality Qigong in cancer care programming may be challenged by the availability of existing programming and work force capacity. The purpose of this discussion is to explore the theory, evidence base, and practice of Qigong for individuals with cancer. Questions addressed are: What is qigong? How does it work? What evidence exists supporting its practice in integrative oncology? What barriers to wide-spread programming access exist
Guo Lin was a Chinese artist and dancer who cured herself of cancer through the practice of Qigong over a ten year period. She modified an old family form of Qigong which she started teaching to cancer patients and people with chronic illness. Her qigong eventually spread throughout China and to some Western countries. In addition to providing a method to treat cancer, Guo Lin basically invented the idea and practice of social oncology.
From a Chinese clinical treatment standpoint, Guo Lin Walking Qigong became the most popular and effective form of Qigong for cancer. It is also known by the names Guo Lin Qigong, Guo-Lin New Qigong, and New Qigong Therapy. There is a short description of it in The Healing Promise of Qi: Creating Extraordinary Wellness Through Qigong and Tai Chi. There is more extensive information in The Healer Within: Using Traditional Chinese Techniques To Release Your Body's Own Medicine, Movement, Massage, Meditation, Breathing The Healer Within: Using Traditional Chinese Techniques To Release Your Body's Own Medicine, Movement, Massage, Meditation, Breathing. More extensive information on the history of Guo Lin Qigong as well as the history of Qigong and its medical use in China can be found in Qigong Fever: Body, Science, and Utopia in China.
The main component of Guo Lin Qigong is breathing a specific way while walking. It is called xi xi hu breathing (xi = inhale, hu = exhale).
Starting at about 12 seconds, people are in lines doing Guo Lin Qigong. Starting at 20 seconds you can hear the instructor saying xi ("she") xi ("she") hu ("who"). In English this is inhale, inhale, exhale. Two inhales as you swing your arms one way, exhale as you swing them to the other. There are variations on how the arms swing from side to side, but the breathing is always two inhales then one exhale. It's not really important how exactly you do the hand and arm movements (for example, how high your arms go, how far you swing your arms, your hand positions -- are they up or down, etc), but you do want them to be coordinated with the breathing. Breathing is coordinated with moving left or right. Breathing is the most important part of the practice.
There is more information on Guo Lin Qigong in the Qigong and Energy Medicine Database™, including:
Prevention and Recovery from Cancer Through the practice of Guo Lin’s “ new qigong therapy”: Cancer patient practitioners of Guo Lin New qigong therapy have experienced optimism, gradual to complete elimination of side effects from chemotherapy and radiation treatments, shrinkage to complete reduction of tumors and even other ailments or chronic disease in the body have been eliminated.
Influence of Guo Lin new qigong on the lung function microcirculation in cancer patients: After continuous exercise of Guo-Lin Qigong more than 2 months, we conclude that Guo-Lin Qigong can improve the lung function and microcirculation of cancer patients.
The practice of Guo Lin qigong can enhance the immune system-assisting in the prevention and recovery from cancer: With 26 years of medical experiences with Guo Lin Qigong, it has proven that Guo Lin Qigong is of great benefit for all cancer patients; irrespective of the stage of their uterus, digestive tract, intestines, esophagus, leukemia or the lymph gland. To date, we have treated tens of thousands of patients from approximately 25 countries throughout Asia, the America and Europe. Through laboratory experiments in China, it has been found that oxygen is the enemy of cancer cells, which cannot exist among oxygen. Guo Lin Qigong therapy increases the oxygen content in the blood. Many positive results can occur with three to six months of practice.
There is a strong social interaction component to the practice of Guo Lin Qigong for cancer. In the United States, this is now referred to as social oncology.

Tai Ji Quan for the aging cancer survivor: Mitigating the accelerated development of disability, falls, and cardiovascular disease from cancer treatment. Currently there are more than 13.7 million cancer survivors living in the U.S., and that figure is projected to increase by 31% in the next decade, adding another 4 million cancer survivors into the healthcare system. Cancer is largely a disease of aging, and the aging of the population will sharply raise the proportion of older cancer survivors, many of whom will be long-term survivors (5+ years post diagnosis). This review will address the potential utility of exercise to address three health problems that are of particular concern for the aging cancer survivor and the healthcare system, i.e., disability, falls, and cardiovascular disease, because the development of these age-related problems may be accelerated by cancer treatment. While there are many different modes of exercise that each produce specific adaptations, Tai Ji Quan may be a particularly suitable strategy to mitigate the development of age- and cancer-treatment-related problems. Based on studies in older adults without cancer, Tai Ji Quan produces musculoskeletal and cardiometabolic adaptations and is more easily performed by older adults due to its low energy cost and slower movement patterns. Since cancer survivors are mostly older, inactive, and often physically limited by the lingering side effects of treatment, they need to engage in safe, practical, and effective modes of exercise. The dearth of published controlled trials examining the efficacy of Tai Ji Quan to mitigate cancer-treatment-related musculoskeletal and cardiovascular side effects points to ample research opportunities to explore the application of this non-Western exercise modality to improve long-term outcomes for aging cancer survivors.
3-month Randomized Controlled Trial finds Tai Chi reduces cellular inflammation and genes encoding proinflammatory mediators. Given the link between inflammation and cancer, these findings provide an evidence-based molecular framework to understand the potential beneficial effects of Tai Chi on cancer survivorship.
Human Body Microbes Make Antibiotics, Study Finds. Each of us has a microbiome which is a component of our 'healer within' and is a major beneficiary of Qigong practice. Our microbiome can be considered part of our internal "pharmacy" where we can get safe and natural personalized drugs. New research, funded in part by NCCAM, suggests that some of the bacteria that share our human bodies manufacture antibiotics and that these substances may be capable of fighting infection. The researchers, from the University of California, San Francisco; the University of California, Santa Cruz; Indiana University; Washington University School of Medicine; and Harvard Medical School, published their findings in a recent issue of the journal Cell: A systematic analysis of biosynthetic gene clusters in the human microbiome reveals a common family of antibiotics.
St. Jude Children’s Research Hospital Combines Mind/Body Practice and Nutrition for Cancer Therapy.

Even though yoga was compared to controls that did not do any exercise, a targeted yoga intervention led to significant improvements in fatigue and vigor among breast cancer survivors with persistent fatigue symptoms.
Psychiatric benefits of integrative therapies in patients with cancer. The active referral of patients to integrative therapies achieves three important objectives: complementary care is received from therapists experienced in working with cancer patients, visits become part of the medical record, allowing treatment teams to guide individuals in maximizing benefit, and patients are diverted from useless or harmful 'alternatives.' We review the reciprocal physical and psychiatric benefits of exercise, mind-body practices, massage, acupuncture, and music therapy for cancer survivors, and suggest how their use can augment mainstream psychiatric interventions.
Energy therapies in oncology nursing. Reiki, Therapeutic Touch, and Healing Touch are recommended during cancer treatment.
Biofield therapies and cancer-related symptoms: a review. This article provides a study review of the main BTs (i.e., therapeutic touch, healing touch, and Reiki) in the treatment of cancer-related symptoms. Although BTs are among the most ancient healing practices, data on their effectiveness are poor and additional multicenter research with larger samples are necessary. BTs may eventually become an autonomous field of nursing activity and allow professionals to build a relationship with the patient, thereby improving motivation. The idea that this method can be self-managed and may effectively reduce pain for patients with cancer can improve satisfaction challenges experienced by the current healthcare system.

Lifestyle includes western-style exercise, mind-body practice, and nutrition.
Cancer is a Preventable Disease that Requires Major Lifestyle Changes. This year, more than 1 million Americans and more than 10 million people worldwide are expected to be diagnosed with cancer, a disease commonly believed to be preventable. Only 5–10% of all cancer cases can be attributed to genetic defects, whereas the remaining 90–95% have their roots in the environment and lifestyle. The lifestyle factors include cigarette smoking, diet (fried foods, red meat), alcohol, sun exposure, environmental pollutants, infections, stress, obesity, and physical inactivity.

An Overview of Sub-Cellular Mechanisms Involved in the Action of TTFields. In this review, we provide an assessment of possible physical interactions between 100 kHz range alternating electric fields and biological cells in general and their nano-scale subcellular structures in particular. This is intended to mechanistically elucidate the observed strong disruptive effects in cancer cells.
Microsecond and nanosecond electric pulses in cancer treatments. The aim of this review is to summarize the present data on the electroporation-based techniques: electrochemotherapy (ECT), nanosecond pulsed electric fields (nsPEFs), and irreversible electroporation (IRE). ECT is a safe, easy, and efficient technique for the treatment of solid tumors that uses cell-permeabilizing electrical pulses to enhance the activity of a non-permeant (bleomycin) or low permeant (cisplatin) anticancer drug with a very high intrinsic cytotoxicity. The most interesting feature of ECT is its unique ability to selectively kill tumor cells without harming normal surrounding tissue. ECT is already used widely in the clinics in Europe. nsPEFs could represent a drug free, purely electrical cancer therapy. They allow the inhibition of tumor growth, and interestingly, nsPEF can target intracellular organelles.

The field's role in the directional transport of mass particles and electrons, organization of living matter, interactions between systems, and information transfer is extensively analyzed and described. This research represents a new contribution to understanding the biological activity of living cells and describes how cancer can be detected by decreased power in the electromagnetic fields generated by cells.
Non-Invasive In Vivo Characterization of Breast Tumors Using Photon Migration Spectroscopy. Frequency-domain photon migration (FDPM) is a non-invasive optical technique that utilizes intensity-modulated, near-infrared (NIR) light to quantitatively measure optical properties in thick tissues. The metabolic demands of hormonal stimulation and cancer tumor growth are detectable using photon migration techniques. Preliminary studies show that unique breast tumor optical signatures are, in fact, detectable in human subjects. Measurements provide quantitative optical property values that reflect changes in tissue perfusion, oxygen consumption, and cell/matrix development.
The potential of terahertz imaging for cancer diagnosis: A review of investigations to date.The terahertz region lies between the microwave and infrared regions of the electromagnetic spectrum such that it is strongly attenuated by water and very sensitive to water content. Terahertz radiation has very low photon energy and thus it does not pose any ionization hazard for biological tissues. Because of these characteristic properties, there has been an increasing interest in terahertz imaging and spectroscopy for biological applications within the last few years and more and more terahertz spectra are being reported, including spectroscopic studies of cancer. The presence of cancer often causes increased blood supply to affected tissues and a local increase in tissue water content may be observed: this acts as a natural contrast mechanism for terahertz imaging of cancer. Furthermore the structural changes that occur in affected tissues have also been shown to contribute to terahertz image contrast. This paper introduces terahertz technology and provides a short review of recent advances in terahertz imaging and spectroscopy techniques. In particular investigations relating to the potential of terahertz imaging and spectroscopy for cancer diagnosis will be highlighted.
Low-pressure pulsed focused ultrasound with microbubbles promotes an anticancer immunological response. High-intensity focused-ultrasound (HIFU) has been successfully employed for thermal ablation of tumors in clinical settings. Continuous- or pulsed-mode HIFU may also induce a host antitumor immune response, mainly through expansion of antigen-presenting cells in response to increased cellular debris and through increased macrophage activation/infiltration. Here we demonstrated that another form of focused ultrasound delivery, using low-pressure, pulsed-mode exposure in the presence of microbubbles (MBs), may also trigger an antitumor immunological response and inhibit tumor growth.
Optimization of a therapeutic electromagnetic field (EMF) to retard breast cancer tumor growth and vascularity. It is proposed that EMF therapy aimed at suppression of tumor growth and vascularization may prove a safe alternative for patients whether they are or are not candidates for conventional cancer therapy.

Bio-effects of non-ionizing electromagnetic fields (EMF) in context of cancer therapy. The therapeutic advantages of EMF could be effectively harnessed for the treatment of cancer and other diseases. This review examines recent findings relating to the mechanisms of action underlying the bio-effects induced by non-ionizing EMF. It's encouraging to see that the study of the use of electromagnetic fields in healing, especially for cancer, is coming out of the closet. Too many tens of billions of dollars have been misappropriated on the pursuit of ineffective genetic and pharmaceutical treatments for chronic conditions instead of more promising energy-based treatments.

Inhibitory Effects of Bio-Energy Therapies on Cancer Growth. An overview of recent laboratory studies in the U.S. and its implications in cancer treatment. Encouraging evidence suggests bioenergy may have inhibitory effects on cancer growth, or prolong the life of cancer-infected animals, although improvement is needed in research design and replication of the findings. Bioenergy for cancer treatment is an area that is often neglected by mainstream medicine and research, and it should be seriously examined and considered as an important supplement to conventional cancer treatment.
Beating breast cancer. Targeted radiation shortens treatment, reduces side effects. Advances in diagnosis and treatment of breast cancer in recent years have often been driven by improved radiologic tools. More precise diagnostic imaging methods such as digital mammography, MRI and 3-D ultrasound have allowed us to detect cancer cells at earlier and more curable stages. At the same time, the development of more targeted radiotherapies in cancer treatment has provided the capability to focus directly on tumors while protecting healthy parts of the body from harmful side effects.
Bioelectric signals can be used to detect early cancer. Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes.
