Effects of radiation on healthy cells
I thought that any healthy cells next to the prostate would die and never come back. According to Mayo's website in Florida it says "Radiation therapy damages cells by destroying their genetic material. Genetic material controls how cells grow and divide. Healthy cells may be damaged along with cancer cells during radiation therapy. But healthy cells can repair themselves more easily than cancer cells." The key word here is "can" and not "will". However, it is still comforting to know that such cells may regenerate themselves.
