Anytime, I just remembered this myself, which could be a cause, contributer or may not be related at all, but at least is an area of interest. I heard of human growth hormone being used too, but with microscopic cancer, I don't know about it's use. Many conditions are rare, uncommon, and not likly to happen, but just reading them can cause anxiety, and does so with me until I read further and discuss it with the real doctor lol. Be well, and keep in touch.
