The hormone, when used in combination with current treatments, may reprogram estrogen action in the breast to improve cancer outcomes. Two new clinical trials are underway to test this approach.
Researchers report good results in patients with metastatic prostate cancer using bipolar androgen therapy (BAT), which alternately floods and starves the body of testosterone. The treatment has been safe and effective, with PSA levels falling, tumors shrinking, and some men showing a complete remission.
Starting testosterone treatment increases risk of serious blood clots, with the risk peaking within six months and declining gradually thereafter. Although the risks are temporary and low in absolute terms, researchers warn that investigating timing and duration of use may have masked conflicting findings.
