Terapia com testosterona em cancro da próstata?

Resultados promissores em que em vez de suprimir os níveis de testosterona aos pacientes com cancro da próstata como se costuma se dão doses elevadas seguidas de um intervalo. A testosterona afecta o DNA da células cancerosas tornando-as "senis" (deixando de causar grandes problemas):

Citando:
"A radical therapy is showing promising results in the fight against prostate cancer. At a medical symposium in Europe this week, researchers reported that "shocking" prostate tumors by rapidly elevating and then dropping men's testosterone levels interfered with the cancer's growth."

"Technically referred to as bipolar androgen therapy (BAT), the treatment is aimed at patients who have metastatic prostate cancer that's otherwise resistant to treatment by chemical or surgical castration. It's based on the idea, supported by previous studies, that high doses of testosterone can interfere with cancer cell division in some cases, and actually cause some cancer cells to make breaks in their own DNA."
