question: Helo doctor, I am a male. I have discovered a lump in my right chest area, just below my nipple. It appears to be roughly 3-5 cm in diameter, movable against all surrounding tissue, and it feels smooth, even-shaped, and firm but not hard, rather elastic. No pain, no visible changes from outside. I am 49 years old and have the following established preexisting conditions like Hashimoto's, slight hypertension, migraines since childhood, and some allergies. I do have recurrent episodes of polyuria for many years that were diagnosed as stress-related some years ago after all differentials had been excluded. A blood panel ordered by my GP now returns a slightly elevated free beta HCG level (3.24 mIU/ml with a reference value of 3.0 for males). All other results including CBC are normal, PSA and AFP, as well as HCG are negative, sexual hormones panel is normal. I cannot detect any abnormalities with my testicles. I understand that any detected beta HCG in males indicates a malignancy. How worried should I be?
