Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I'm 50yr old male, never drink, smoke or drugs. I eat cleanly, exercise and drink approx 1 gal water daily. I just noticed a small painless lump (smaller than the end of my pinky and under the skin) under my left armpit. The only thing I've ever been treated for is prostate cancer 10yrs ago - and 1yr ago my PSA came back at 0.01...just wondering how concerned I should be?
