I was diagnosed (not at Mayo) with LAMN (low-grade appendiceal mucinous neoplasm) 1.5 years ago and just had CRS (debulking), not sure really why just that. Having just CRS done by slicing me open, I really had very little pain & recovery was pretty easy. I was 72 then.
3 CT's and tumor marker blood tests later, still ok, but asking help from Mayo as I just don't feel as good as I think I should.
Best of luck to you.
