While prostate cancer is the most common cancer in elderly Western men it also, but more rarely, strikes patients aged between 35 and 50. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, in collaboration with several other research teams in Germany, have discovered that such early-onset prostate cancers are triggered by a different mechanism from that which causes the disease at a later age.

Enzalutamide shows promise in treating triple-negative and estrogen-positive breast cancer

Breast cancers are defined by their drivers - estrogen and progesterone receptors (ER and PR) and HER2 are the most common, and there are drugs targeting each. When breast cancer has an unknown driver, it also has fewer treatment options - this aggressive form of breast cancer without ER, PR or HER2, which was thought not to be driven by hormones, is known as triple negative.
