Breast cancer survivors, if they practise yoga for as little as three months, may significantly reduce fatigue and inflammation, shows research.

“Modest yoga practise over a period of several months could have substantial benefits for breast cancer survivors,” claimed Janice Kiecolt-Glaser, professor of psychiatry and psychology at Ohio State University in the US.

“The results could easily generalise to other groups of people who have issues with fatigue and inflammation,” added Kiecolt-Glaser.

To reach this conclusion, researchers asked 200 participants to practise yoga in small groups twice a week for 12 weeks.

Women in the control group were instructed to perform normal routines and not to do yoga.

Results showed that on average, fatigue was 57 percent lower in women who had practiced yoga compared to the non-yoga group, and their inflammation was reduced by up to 20 percent.

“The participants had completed all breast cancer treatments before the start of the study,” said the study published in the Journal of Clinical Oncology.

The more the women in the study practised yoga, the better their results.

“Though many studies have suggested that yoga has numerous benefits, this is the largest known randomised controlled trial that includes biological measures,” Kiecolt-Glaser said.

Chronic inflammation is linked to numerous health problems, including coronary heart disease, type 2 diabetes, arthritis and alzheimer’s disease.

A secondary analysis showed that more frequent yoga practise produced larger changes in fatigue, vitality and depressive symptoms as well as between an average 4 to 6 percent reduction in two of the three pro-inflammatory cytokines.

The yoga group also reported significantly improved sleep compared to the control group.

“Yoga has many parts to it – meditation, breathing, stretching and strengthening. We think the breathing and meditation components were really important in terms of some of the changes we were seeing,” Kiecolt-Glaser stressed.

Reducing fatigue enables women to engage in other activities over time. So yoga may have offered a variety of benefits in addition to the yoga exercises themselves, added the study. (IANS)

Chinese Researchers Reveal Mechanism of Chronic Stress Promoting Breast Cancer Development

Chinese researchers have revealed the mechanism of how chronic stress promotes breast cancer development, shedding light on future clinical treatment for cancer.

Cancer patients often suffer negative emotions such as anxiety, despair and fear, which are risk factors facilitating tumour growth as well as promoting cancer progression. However, the specific mechanisms of how chronic stress affects cancer development remains unknown yet.

Researchers from the Dalian Medical University in China found that chronic stress might increase epinephrine levels, which enhances lactate dehydrogenase A (LDHA) and promotes breast cancer stem-like cells, Xinhua reported.

Using a drug screen that targeted LDHA, they found that Vitamin C reversed the chronic stress-induced cancer stem-like phenotype.

The study demonstrates the critical importance of psychological factors in promoting stem-like properties in breast cancer cells and provides a promising therapeutic approach for breast cancer, according to Liu Qiang, lead researcher at the varsity.

“The LDHA-lowering agent Vitamin C can be a potential approach for combating stress-associated breast cancer,” Qiang said, in the paper published in the Journal of Clinical Investigation.

His team has been engaged in the dynamic regulation of cancer stem cells research as well as the mechanism of psychosocial behaviour affecting tumour development.

Qiang noted that patients with breast cancer, ovarian cancer and stomach cancer often have negative emotions, which in turn accelerates the development of their own tumours.

“It is necessary to monitor their chronic stress comprehensively by taking psychological assessments as well as conducting blood tests which include epinephrine levels,” Qiang said. (IANS)
