Yes, my first doctor kept telling me he wasn't ready to say the C word yet and he seemed baffled when no cancer was detected a year later. I found a new doctor , who done a ct and now he is concerned about cancer, but my lymph nodes were fine. Now he is eager to do a third biopsy asap or wait three months to do a new scan. I've read several comments about doctors suspecting cancer in Mac patients but was later found to be none. Good luck with everything.
