I'm a 23 year old female worried I may have a pancoast tumor. I'm a rather nervous person with a history of anxiety but lately it's peen the pain that worries me. I went to urgent care and was declared clear through urinalysis and blood work but my pain persists. The doctor said it may be a pinched nerve but didn't investigate. The pain is centered around my left armpit extending a little towards my chest and into my bicep. It's not excruciating but definitely bothersome. My left shoulder blade hurts a little too but not that bad. It doesn't bother me when I sleep but I cannot escape the fear its a sign of pancoast. My father recently passed away from lung cancer and had never smoked in his life, while I have casually dabbled. Would you suggest I get a ct scan? I have read x rays often miss these masses. Thank you in advance
