What is often blocked in the treatment of prostate cancer to manage the disease?

  1. Estrogen

  2. Progesterone

  3. Testosterone

  4. Cortisol

The correct answer is: Testosterone

Prostate cancer is hormone sensitive, meaning that hormones can stimulate its growth if present in high levels. Therefore, in the treatment of prostate cancer, testosterone is often blocked in order to prevent its stimulating effects on the cancer cells. Other hormones such as estrogen and progesterone do not have the same effect on prostate cancer growth and are not typically used in treatment. Cortisol, a stress hormone, is also not involved in prostate cancer treatment. Therefore, the correct answer is C, testosterone.
