Lung nodule 9cm

hi @sullivan728 - welcome to Mayo Connect. the short answer is maybe. there can also be benign lung nodules and PET scans aren't great at reading smaller nodules. it sounds like further testing is warranted. do you have a pulmonologist that can order the recommended CT scan?

Hello @sullivan728, there often isn't one clear answer in these situations. It usually takes a few scans and maybe a biopsy to get a clear answer. It's a good sign that the PET scan results are not clear. If the uptake numbers were high, then it would likely be cancer. Even then, without a biopsy there is no definitive answer. I'm a stage IV lung cancer patient, with a 1 cm fungal nodule. Our lungs react (and sometimes overreact) to all sorts of foreign bodies.
What prompted the PET scan, prior to a CT?
Can you clarify, is this mass 9cm (as the message subject indicates) or 9mm?
