A single high-intensity workout may slow breast cancer cell growth, study finds
A finding with immediate relevance for Thai cancer care: a single session of intense exercise can release protective molecules into the blood that slow the growth of breast cancer cells in the lab. The study followed 32 women who had completed breast cancer treatment and compared two strenuous exercise approaches—high-intensity interval training and weightlifting. Blood drawn after these sessions, when added to cultured cancer cells, repeatedly slowed or halted tumor growth, whereas blood drawn before exercise had no effect. The most potent anticancer signals appeared after interval training, led researchers, with a notable rise in a molecule known as IL-6, which influences immune responses and inflammation. In short, exercise does more than improve fitness—it seems to trigger a direct, beneficial biological response that can influence cancer biology.
