A short YouTube medical explainer (by Dr. Charles Mok) stating that available evidence does not support increased prostate cancer risk from testosterone therapy. The speaker debunks a common clinical myth about stopping testosterone during cancer treatment and resuming in remission, and notes that untreated men with low testosterone have higher incidence and more aggressive prostate cancers while men who receive testosterone replacement have similar incidence to men without low testosterone.

The evidence does not support increased risk of prostate cancer with testosterone therapy. This is a common myth that some doctors believe the person that has prostate cancer may be put on testosterone suppressive therapy during treatment, but then they can resume testosterone after they're in remission. In this also, there's no studies supporting increased risk of prostate cancer in men with low T that have replacement of testosterone. Now, low T, low testosterone men who are untreated have higher incidence and more aggressive cancers, but when they're treated, they have the same incidence of prostate cancer is other men that do not have low teeth and not have testosterone replacement.
