Restricter, the biopsy is certainly more invasive than anything else he's had done, but if it definitively diagnoses lymphoma AND the oncologist feels he has a good chance for remission and extended life, then the benefit outweighs the risks. Unless of course, you decide not to do chemo, in which case there's no reason to do a biopsy. So what you need to find out is the odds of success of chemo and the average life span after chemo. If the life expectancy with chemo is not much more than without, no reason to put him through anything more, just keep him happy. I know that the success rate for renal lymphoma is not as good as with other types, but with him feeling good and having normal kidney values, he might stand a better chance of remission. The oncologist should be able to give you more precise numbers and prognosis. No matter what others tell you, you need to be at peace with the decision you make, whether it's about the biopsy or about going forward with chemo. No point in doing the medically "right" thing if you lose sleep and have doubts about whether it's best for
Winky. I think whatever you choose, you can know that you've gotten as much information as you can and are making as informed a decision as possible.
