Hi Alison -
Both biopsies are in the chest area, one in my upper left lobe (a growth of some sort, maybe maximum of 1.8 inches across, very roughly) and one "area of concern" roughly at my sternum, that was interpreted (due to unusually high glucose take-up) from a recent positron emission tomography (PET-) scan imagery. It's the pulmonologist who is spearheading the cancer quest, and I think it's his "pet" theory that cancer cells could have "confused" (my term) the autoimmune system and led (since those cells are coded as "my body") to a myositis "behavior" of attacking my musculature, etc., as myositis does.
The rheumatologist, on the other hand, while anxious to rule cancer out in a "general way" and thus supportive of CT-scanning and other testing (such as colonoscopy) is more skeptical, I think, regarding the likelihood of a "cancer genesis" for the myositis.
Thanks for good wishes! Here's hoping I don't need them (too much). There are answers I just don't want to get...
Greg
