A 29-year-old female asked:

Ive had a small, itchy rash and hard lump in my armpit area for a month now. i dont know if an allergic reaction to a deodorant could cause this or when/if i should see a dr to check for cancer. i am still using same deodorant twice a week. ?

Possibilities: This can also be caused by a fungus that has been transferred to the site on your fingers. There are lymph nodes and glands under that skin & they can become infected or react to stimulation there. Moist heat may permit enough improved blood flow to allow the area to heal, but you may just need to have the site examined. Cancer would be very far down at the bottom of the list of possibilities.

Agree with Dr. F: Stop using the anti-perspirant as it may be causing local inflammation. If the lesions do not subside or at least show improvement in a week or so, it would be prudent to see your doctor.
