What are the signs of existing a tumor in the brain or the respiratory system?
My mother feels a bad smell in his nose.It is something like the cigarette smoke.She has headache in the mornings and then it wears off.This stink or odor sometimes reduces and some days increases.My mother has always had splitting headaches during her life.Can these contribute to a tumor in the brain?Also,recently the CT of her mind showed nothing of a tumor or the like .The doctors say that she has no problem.But continuously she feels that smell.
