    negative biopsy
    mrbozo123 posted:
    My 85 year old father has had two biopsies of a small lung tumor over the last 6 months after it was detected during a CAT Scan. Both biopsies were negative. He is about to undergo Cyberknife treatments for the lung tumor. My father lives in another state and I couldn't convince him to get a second opinion and he couldn't explain to me the rational for going ahead with the Cyberknife treatment. Is it typical for cancer treatments to be done without a positive biopsy?

    web md has a lung and repritory health center that discusses tumors. I pesonnaly would get a second opinion to include interpretations of the biopsy by another pathologist.
