I agree this board is not very active! However, it is true that biopsy is the best way to dx lymphoma. Needle biopsies are not reliable and often result in excisional biopsies being done. I had to have surgery on enlarged lymph nodes that showed up on a ct scan in my abdomen and the results were lymphoma. Even if it is, there are lots of treatments and the more aggressive lymphomas are curable. The indolent ones are not curable but treatable.
Hope you find out what is going on soon,
Love and prayers,
