BB, I found this article on the PCRI web site: http://www.prostate-cancer.org/pcricms/node/197.
"Radiation to the breast (usually just around the nipples) before the start of testosterone deprivation therapy can reduce the risk of breast growth and tenderness by as much as 65%.17 This is especially important for a man to discuss with his medical provider prior to starting monotherapy with Casodex® or Eulexin®, because of the high incidence of breast growth and tenderness with this type of testosterone blocking treatment."
I'm glad you keep asking these questions because I need to learn everything I can, just in case. Hope this helps.
