And that's a very valid point indeed..., and the medical community knows it, so there's no point dancing around the issue.
My ears are aching from constantly hearing about how testosterone might speed up the proliferation, or even cause prostate cancer. Yet, for every time the word prostate cancer is mentioned in the context of male hormone, one ought to also mention the words breast cancer in women (replacing estrogen/progesterone), yet (and that's partly Darkoz's) and my own frustration, it is not mentioned.
As Darkoz has correctly stated, one is encouraged, whilst the other is not only discouraged, but has been ignored all the way since the 1950s until our present day.
