A recent report by Carlo La Vecchia, head of the department of epidemiology at the University of Milan, indicated that if women were to eat less and exercise more, their risk of developing breast cancer would be reduced by as much as 30 percent. Their findings, which are in general agreement with multiple other studies, indicate that regular, vigorous exercise and maintenance of normal weight are associated with significant reduction in the risk of developing breast cancer.

Lymphedema refers to abnormal and persistent swelling and can occur in the arms or legs. Lymphedema occurs when the flow of lymph fluid is obstructed. This condition is usually isolated to a single arm or leg, although it can present itself on multiple limbs.

In America it occurs most commonly after cancer treatment. For example, lymphedema of the arm can develop after mastectomy and lymph node removal procedures.
