As you are aware my husband has decided to try for another tissue testing option. The recent pet ct can sowed some new mediastinal lymph nodes lighting up so we thought we should do a biopsy by taking tissue from these mediastinal lymph nodes.
My question is, will tissue taken from these nodes be good enough for mutation testing. Although he is still on Tarceva, he is showing some progression so we want to keep ahead of the cancer.
How expert should a surgeon be to be able to perform such a procedure?
Thank you for listening
