My mare Bella is in her last stage of Melanoma cancer. Recently one of these tumors ruptured, and then fell off.... It was on the underside of her tail, and when it fell off it took her whole underside of her tail with it. My BO has been scrubbing it with Betadine solution, and although it's getting better, I am not sure if it may be to harsh of a treatment. She hadn't really had a problem with tumors rupturing, but now it seems every week one bursts, and I can't help but think it's the Betadine. I would stop treatment, but I don't know what else to use.... Maybe Turpentine??? I have no idea, any suggestions?
If pictures will help I will get some on Sunday when I go up to the barn.
