What cancer causes swollen lymph nodes in armpit?

Question

I've noticed a swollen lump under my armpit and it's been there for a few weeks now. My mother is worried it might be a swollen lymph node and she's asking if this can be a sign of cancer.

While breast cancer or lymphoma can sometimes cause swelling in the armpit lymph nodes, my family doc told me that simple infections are way more common. Scratching, shaving cuts, or even a recent vaccine can trigger these nodes to swell up. Definitely get a physical exam and an ultrasound if the swelling doesn't go away in two weeks.

I literally spend hours on Google whenever my body acts up and I know how terrifying these thoughts are. Honestly, last time I had an armpit lump, I was convinced it was cancer, but it turned out to be a blocked sweat gland. Please breathe and go to a doctor so you can get peace of mind instead of worrying.

In my experience, managing my high BP has taught me that we need to do regular body checkups anyway. Whenever anything unusual like a lump appears, it is best to get a doctor's opinion immediately. Along with that, try to maintain a calm routine and don't let stress make your health worse.

With things like swollen lymph nodes, you should never take a chance or wait too long. It is always better to get a proper checkup from an oncologist or physician to rule out anything serious. Early detection makes everything easier, so please book an appointment.

I had a tiny sore lump under my arm once after a heavy upper body workout session, which was just a strained muscle and minor inflammation. Keep doing your daily light walking to keep your circulation good, but don't do heavy exercises till you show this to a physician. Let a doctor examine it properly first.
