Yes, unfortunately, CLL is tough to permanently beat. I also recently learned that there are 200 types of cancer. If there are 200 types of cancer, all the money in the world can't bring about enough research to permanently cure 200 types of cancer. LOL. I hope for humanity's sake that one day a cure is found that will stop at least, oh,.....25 of them? For that matter, is there a permanent cure for even one type of cancer? 😀
