One of the primary reasons exercise works to lower your cancer risk is because it drives your insulin levels down, and controlling insulin levels is one of the most powerful ways to reduce your cancer risks. It’s also been suggested that apoptosis (programmed cell death) is triggered by exercise, causing cancer cells to die.
Exercise also helps lower your estrogen levels, which explains why exercise appears to be particularly potent against breast cancer. And if you’re male, be aware that athletes have lower levels of circulating testosterone than non-athletes, and similar to the association between estrogen levels and breast cancer in women, testosterone is known to influence the development of prostate cancer in men.
Then of course, exercise also improves the circulation of immune cells in your blood, whose job it is to neutralize pathogens throughout your body. The better these cells circulate, the more efficient your immune system is at locating and defending against viruses and diseases, including cancer, trying to attack your body.
Exercise Tips for Cancer Patients
I would strongly recommend you read up on my Peak Fitness program, which includes high-intensity exercises that can reduce your exercise time while actually improving your benefits.
Now, if you have cancer or any other chronic disease, you will of course need to tailor your exercise routine to your individual scenario, taking into account your stamina and current health. Often, you will be able to take part in a regular exercise program — one that involves a variety of exercises like strength training, core-building, stretching, aerobic and anaerobic — with very little changes necessary. However, at times you may find you need to exercise at a lower intensity, or for shorter durations.
Always listen to your body and if you feel you need a break, take time to rest. But even exercising for just a few minutes a day is better than not exercising at all, and you’ll likely find that your stamina increases and you’re able to complete more challenging workouts with each passing day.
In the event you are suffering from a very weakened immune system, you may want to exercise in your home instead of visiting a public gym. But remember that exercise will ultimately help to boost your immune system, so it’s very important to continue with your program, even if you suffer from chronic illness or cancer.
