Did cancer treatment increase my heart disease risk?

DEAR DOCTOR K: I survived cancer, only to be told that the treatments that saved my life may have increased my risk for cardiovascular disease. What are the risks? And can I minimize them?
DEAR READER: As more people are living longer after a cancer diagnosis, more people are coping with the long-term effects of cancer treatment. Many cancer-suppressing treatments can have undesirable effects, for example, on the heart and blood vessels.
