I hate to diet. I’m lazy and don’t exercise much. But I hate cancer more:

Cancer survivors should exercise more and improve their diets to help prevent the disease from coming back, the American Cancer Society said in releasing new guidelines Thursday, saying there’s now enough evidence to strongly recommend physical activity and better nutrition for survivors.

The message: For many cancers, maintaining a healthy weight, exercising and eating a healthy diet can reduce the risk that cancer will return.

Two other groups have issued similar advice, but the cancer society’s endorsement is expected to have greater impact. It’s the nation’s richest charity in both donations and volunteers and the largest non-governmental funder of cancer research.
