Radiation therapy to the whole breast or chest wall and the internal mammary lymph nodes can deliver a radiation dose to the heart that increases the risk of cardiovascular events. To see whether proton therapy can reduce this risk, a multi-institutional clinical trial is comparing proton therapy to standard photon-based radiation therapy for patients with locally advanced breast cancer.

The good news is death rates continue to decline for the most common types of cancer, including lung, colon, breast and prostate.

The bad news is a far less common head and neck cancer is rising sharply. Since the late 1980s, cases of oropharyngeal cancers that attack the back of the throat, the base of the tongue and the tonsils have jumped 225%. According to the Centers for Disease Control and Prevention, almost three-fourths...
