While prostate cancer is the second most frequent cancer diagnoses for men in the world today, our body often throws cancer cells at us that our immune systems have to naturally combat with Natural Killer (NK) cells. These cells are one of the few defences our body has against threats that are self created. Of course all of our bodies natural defence relies solely on our immune system staying healthy and active.
While chemotherapy remains the most popular treatment among most cancer victims it is the very treatment that brings down your immune system dramatically. Chemotherapy devastates healthy cells along with the cancer cells it aims to destroy, gradually chipping away at the other defences your body provides . While Chemotherapy is still always advised there have been studies to show some alternative methods that can help in the fight against certain cancers.
Sweden may have the beginnings of an alternative method that won’t wreak havoc on your immune system. A small study has been performed among 10 young, healthy men. Their blood was taken before and after performing an average of 65 minutes on an exercise bike. Their blood was then spun to extract the clear serum from said blood and incubated with prostate cancer cells for up to 96 hours at a time. Incredibly 9 out 10 subjects exercise serum suppressed the cancer cell growth by 31%. This proves a significant decrease in growth rate and possible fending off of metastasis.
Long term exercise has long been proven to reduce levels of growth stimulating hormones in the body but now we have an acute exercise study that has shown to reduce the rate of cancer cell production. While it doesn’t destroy existing cancer cells (apoptosis) it does significantly decrease the rate at which new cells are created (reduced proliferation).
While being a relatively small experiment this is a foot in the door of further study on the potentially beneficial effects of different forms of exercise on existing cancer cells. This topic has long been debated among the scientific community and now finally has some hard proof to back up the claims of positive outcomes.
