remarkable study looked at how blood serum taken from men post-exercise dramatically inhibited the growth of cancer cells.

The experiment took 23 young men, average age 22, and had them do a bout of high-intensity cycling, 6 1-minute intervals at 90% max, with 1-minute rest intervals in-between. They had blood drawn before the bout, and then at 5 minutes, 1 hour, and 24 hours post exercise. The blood was centrifuged and the serum (liquid part) was placed into media that contained cancer cells, which were different types of non-small cell lung cancer cells. Controls were cells grown in their usual media, without human serum added. The cells were allowed to grow for 7 days, and then counted. Chart below shows the results.


Huge inhibition of cancer growth, up to 75% using serum taken 5 minutes post-exercise.

Why does this happen? One possibility is lack of growth factors. Insulin was not a factor, since they found no difference in insulin between pre- and post-exercise specimens, but IGF-1 (insulin-like growth factor 1) was different, so that may be the answer.

There’s also evidence that can let us speculate that weight lifting might be superior in this regard (as I’ve long maintained), because molecules secreted by exercising muscle, called myokines, may be involved in suppression of cancer growth.

Basically, every bout of intense exercise floods your bloodstream with anti-cancer molecules, and/or it removes pro-cancer molecules.

This isn’t the only study that has found such an effect.
