from what i have read the only cancer that is thought to be caused by a/a/s abuse would be liver cancer--
while there is some talk about prostate cancer (but the biobrains appear to be in that dark re: prostate cancer) so....
the real risk to long term a/a/s/ abuse is heart attack/stroke if you do not keep you cholesterol under control--but even then there are people who disagree....
i read an article that said the most dangerous, life threatening thing you can do is not brush your teeth---b/c of plaque entering the bloodstream fairly easily....
Now, g.h/IGF is a whole different story.....
