i give my self a breast exam twice a week and secretion check of the armpit. i was told some years ago that useing deodorant every day was not a good idea because it blocks your pores and could help in the process of getting or worsening cancer cells growth within that area; i dont use deodorant unless i go to work or some kind of special event . so when i ware deodorant its on me for 5-6 hours then i wash it off as soon as i can . within the pass month i have used deodorant almost every day because of my new relationship. on top of that because i didnt use deodorant that often i wouldnt shave but 2-4 times a week; now every day . i was giving my self an exam and found a small lump under my armpit . this lump feels close to the skin and is very sore to the touch and feels every close to touching the lump nodes that fallow into the breast its about an inch around. Could this be cancer , an ingrown hair from shaving more, or is this just my body not liking this attention that its getting in that area?
