How Exercise May Aid Cancer Treatment
The New York Times

In a new study involving mice, aerobic exercise slowed the growth of breast cancer tumors and made the cancer more sensitive to chemotherapy. The results raise the possibility that exercise may change the biology of some malignant tumors, potentially making them easier to treat.

Scientists and clinicians have known for some time that solid tumors can create their own, peculiar ecosystem within the body. As a tumor grows, it sends out biochemical signals that prompt the creation of additional blood vessels to provide the expanding tumor with more oxygen. Oxygen is, of course, important for cell health, including in normal tissue.
