I am a bit unsure about the answer to this one, but I assumed you couldnt feel lymph nodes are they were very small. Do you have a breast care nurse? With medical questions I advise you to save the guess work and ring some one who would know. I had a great bc nurse to hound. I also rang everyone from the hospital I had my Chemo with, to the nurses, doctors, and cancer council. I dont feel constantly, I just apply moisturiser and have a general feel of my breasts, funny I never think about my underarm as the lump was in my breast. oops
