ok im 15 and i fear that i might have both bowel and testicular cancer. i have seen some small amounts of blood in my stools and on the tissue (but that could be haemorrhoids, im not sure yet). i also have a sharp pain that will come and go in my right testicle and the right side of my abdomen, but there are no lumps anywhere. i have not yet seen a doctor but will go and see one soon.
