What are possible causes of a small lump under my armpit?Skin, Hair & Nails Breast Cancer Cancer
I'm a 26 year old female. I exercise regularly and eat relatively healthy. Recently I discovered a small lump under my right armpit. It's slightly bigger than a cherry seed, and gets a bit tender when pressed. My family has no history of breast cancer, although my mother has a similar (but larger) lump under her left armpit. Should I be worried, and what can I do?
Thank you for your question. There can be multiple causes of a lump affecting the armpit. The common causes would be an ingrown hair, infection of a hair follicle, cysts or lipomas. The more worrying causes like an enlarged lymph node due to breast cancer must also be excluded.
It is most important for you to see a doctor to ascertain the cause of your lump.
Most of these lumps can be easily treated with antibiotics or simple surgery to remove the lump, depending on the cause. I would encourage you to seek help from a doctor or dermatologist as soon as possible, so they can check you over and you no longer have to worry alone.
Hope this is helpful!
