Free radicals linked to heart damage caused by cancer

A new study in animal models shows that the presence of a cancer tumor alone can lead to cardiac damage, and suggests the culprits are molecules called free radicals interacting with specific cells in the heart. Adding specific types of antioxidants to food consumed by fruit flies with tumors reversed the damage to their hearts -- a finding suggesting that harm caused by free radicals was the likely link between cancer and cardiac dysfunction.
