It doesn't sound bloody enough to be a cyst/boil.
Most predictable its just an inflamed lymph node from your body combat off a small ailment, there is a possibility albeit small that it could be cancer I would step get checked out.
Also since it is slightly tender to touch its a polite sign that it is NOT cancer, but still go win checked.
Go to the doctor as soon as possible. It may be a swollen lymph gland. Could also be a sign of breast cancer.
see a doctor it could be a lymp node or cancer
could be a boil
Could also be a cyst or spider bite, if its around bone could aslo be a calcium deposit, although under arm is uncommon place for that. go to doctor
It could be something as simple as an inflamed hackle follicle or something as serious as cancer. We can't answer that , so the best advice is to shift see a doctor. I would rather spend $200 and find out it be nothing, than to forget about it until it became untreatable and duration threatening. Best wishes. By the way, I'm assuming you propose it's a lump.
