According to the following research this is one of the benefits exercise can provide which may surprise you.

Exercise prevents cancer incidence and recurrence, even if the underlying mechanism behind this relationship remains mostly unknown (Sheinboim D, et al, 2022).

Exercise induces the metabolic reprogramming of internal organs that increases nutrient demand and protects against metastatic colonization by limiting nutrient availability to the tumor. This generates an exercise-induced metabolic shield, according to the researchers.

Under limited glucose conditions, connective tissue and blood vessels consumed significantly more glucose at the expense of the tumor.

Exercise protects against cancer progression and metastasis by inducing a high nutrient demand in internal organs. This indicates reduced nutrient availability to tumor cells.
