In fruit flies, antioxidants reverse tumor-related cardiac dysfunction. 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 are free radicals interacting with specific cells in the heart.

Tumors in mice and fruit flies led to varying degrees of cardiac dysfunction – particularly a decrease in the heart’s blood-pumping capabilities.

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.

The results reinforce previous findings that antioxidants hasten the progression of lung cancer. People with cancer or an elevated risk of developing the disease should avoid nutritional supplements that contain antioxidants, the researchers say. Given well-established evidence that free radicals can cause cancer, the research community had simply assumed that antioxidants, which destroy them, provide protection against the disease.

“As opposed to the lung cancer studies, the primary melanoma tumor was not affected,” Professor Bergö says. “But the antioxidant boosted the ability of the tumor cells to metastasize, an even more serious problem because metastasis is the cause of death in the case of melanoma. The primary tumor is not dangerous per se and is usually removed.”
