Could A Tiny, Pea-sized Lump In My Armpit Be Breast Cancer?

I recently had some pain in my armpit area, and I can feel a small pea-sized bump. It doesn't hurt anymore, but it's still there, though it's gotten a little smaller. Could this have just been an infection, or could it be breast cancer?

Answer

Because this armpit lump is getting smaller, your idea that this might be an infection seems reasonable.    Swollen lymph nodes under the arm are usually  due to an infection; and the lymph nodes can remain swollen for some time after the infection is gone, so you don't necessarily have to feel sick to have swollen lymph nodes.

Unfortunately, armpit lumps can also be a breast cancer symptom. So if this lump doesn't continue to get better within the next two weeks, you'll want to check in with your doctor.  Also, if the signs of infection get worse, such as increased redness or fever, then call the doctor right away.  You might need an antibiotic.  Thankfully, from what you've said, it sounds like there's no need to panic about cancer - just continue to be vigilant.
