CINERUSS
Sorry to hear about your boyfriend's condition. Also, I wish more people would respond than what you normally find in this forum.
First, there are a lot of things to consider when thinking of swollen testicles and tumors. You might want to see if there is a holistic practitioner-one who works with alternative therapies-for advice. Don't let it go too long though. Also, hysterectomies are performed on women. I know it was a typo don't worry about it.
Good luck
