Hello, I am a 33 year old female, non-smoker. I am concerned that I may have a pancoast tumor in my lungs. This is a special type of tumor that sits at the apex of the lungs. I have had 5 chest xrays over the last 2 months, all of them were clean. My doctor won t send me for a CT scan because he says that he doesn t want to expose me to unnecessary radiation . My symptoms include: a burning pain in my right arm and numbness in the last two fingers on my right hand that started at the end of January. The burning and numbness in the right arm have since went away. Now my neck, right shoulder, right upper part of my chest and right arm are sore. My doctor believes this may be caused by a pinched nerve in my neck and muscle spasms/tension. I go for am MRI of the brain and c- spine next week. An EMG on my right arm showed mild carpal tunnel and a right shoulder xray and ultrasound were clean. I am concerned because I still have many right sided symptoms. I have had multiple clean chest x-rays but know that chest x-rays sometimes miss tumors at the apex of the lungs, such as pancoast. Do you think I should believe the 5 clean x-rays? Could this be a pinched nerve? Worried and scared. Michelle
