I have a hard, painful, red lump in my armpit that when pinched between forefinger and thumb does not move . It has been apparent for approx. 4 weeks. It has not changed in size. My overall health is good. No recent illness. I have been using the same roll on deodorant for the past year. I am a 48 year old female, have been going through menopause, without medication, for 2 years. There is a history of breast cancer on my mothers side of the family.
