question: hi , my name is Arwa,am 31 years old, 5 months ago I discovered by accident thay I have a lung mass on my left lung ( it was by a chest x- ray as a routine check up) i did a chest C.T. scan and the radiologist suggest that a needle lung biopsy should be done. I did it , and I had to had a chest tube inserted due to pneumothorax.I lef the hospital after they checked that the air got out of my lung.the lab results assured me that the tissure taken was not malignant, anyway am having now some pain in the site where the mass is supposed to be , and near my neck esp when sneezing , i also feel some weakness in my left arm ?is this normal esp that i didn't have any symptoms before the biobsy?and is there something else that I shoould do? I have a strong family history of cancer,so are the lab results really precise? thanks alot.
