This is pretty opposite of the truth. In the recent NPR podcast they talked about the fact that inventor of rapamycin practically cured himself of late stage cancer (given up to 6m of life, lived 5 years) His cancer was nowhere to be found. Then he decided to prove rapsmycin was the cause, stopped taking it, and died very shortly of cancer. https://www.wnycstudios.org/podcasts/radiolab/articles/dirty...
