A little bit of physical activity drastically increases the survival chances of breast cancer patients

Walking for half an hour 5 days a week will give you the minimum amount of exercise that sports scientists say you need to stay healthy. No, that's not much. But it's enough to dramatically increase the survival rates of women with breast cancer - and significantly reduce the chances of their disease returning.


A little bit of physical activity drastically increases the survival chances of breast cancer patients


Study
The researchers, who are affiliated with Roswell Park Comprehensive Cancer Center, used data from 1,340 women treated for breast cancer who participated in the Diet, Exercise, Lifestyle and Cancer Prognosis Study.

The researchers knew how much the women exercised before, during and 1 and 2 years after their chemotherapy. This enabled them to determine whether the women were meeting the minimum amount of exercise that scientists believe people need to stay healthy: 150 minutes of moderate-intensity exercise per week.

Results
The figures confirmed that a lifestyle with sufficient physical activity reduces the risk of cancer recurrence and improves survival.

For example, in the table below you can see that, compared with the study participants who did not meet the exercise guidelines before, during and after their treatment, the study participants who did exercise enough before, during and 2 years after their treatment had a 55 percent lower risk of their illness. Their chance of dying was 68 percent less.

"These findings have valuable clinical and public health implications because they provide additional evidence to solidify the message that low-volume activity is associated with statistically significant overall survival benefits and is superior to inactivity", the researchers summarize in the last paragraph of their publication.

"This is particularly encouraging given that patients and survivors may be overwhelmed by the most current Physical Activity Guidelines for Americans recommending 150-300 minutes per week of moderate-intensity recreational physical activity or 3 days per week of at least 30 minutes of moderate-intensity structured aerobic exercise for cancer survivors."

Strength training helps women recovering from breast cancer stay attractive and healthy
Breast cancer survivors are often put on hormone therapy for years after they've had chemotherapy and surgery. While it can drastically reduce the chances of a new bout of cancer, hormone therapy leads to muscle and bone-mass loss and an increase of fat.

Low carbohydrate diet protects women with breast cancer during chemotherapy
When women with advanced breast cancer are treated with chemotherapy, their chances of survival increase when they switch to a ketogenic diet.

Each gram of mushroom reduces chance of breast cancer by several percent, says meta-study
This meta-study leaves a lot to be desired. Nevertheless, it does make the theory that edible mushrooms offer protection against breast cancer a little more likely.
