Researchers at the University of California, San Francisco, have successfully leveraged an FDA-approved drug to halt growth of tumors driven by mutations in the RAS gene, which are famously difficult to treat and account for about 1 in 4 cancer deaths.
Taking advantage of what they discovered to be the cancer cells’ appetite for a reactive form of iron, the researchers tweaked an anticancer drug to operate only in these iron-rich cells, leaving other cells to function normally...

The findings are independent of aerobic exercise. But the analysis points to a J-shaped curve for most outcomes, with no conclusive evidence that more than an hour a week of muscle strengthening activity reduces the risk further still.
Physical activity guidelines recommend regular muscle strengthening activities for adults, primarily because of the known benefits for skeletal muscle health...
Read MoreIn 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.
“Cancer becomes a systemic disease...
