Lumps under arm

Hi There rainbow

I have a lump under my left armpitt. My mother and sister have both died from breast cancer, my mum when she was 50 and my sister when she was 38. I am now 37 and will be 38 in this Novemember. I am worried that it may be cancer. I sometimes have a pain and tightness, well more of a tightness than pain, when I lift that arm up. Also if I lay on that side in bed it is as if the blood circulation is being cut to my arm and under my armpitt it is very tight/restricted. I have had an FNA on my right breast which turned out to be ok. Is there anyone who can offer thoughts????

Due to your strong breast cancer history, you'll need to get this lump biopsied.
Swollen lymph node due to cancer isn't painful, feels hard and may cause some discomfort.
Breast cancer can cause swollen lymph node in the armpit, even, when the breast doesn't show any signs of cancer.

Check this as soon as possible!

Thank you for asking at Ehealth forum!

I read your question and I understand your concern.
Lump in the armpit is usually benign or infectious.
But keeping in view your family history, its better to do excisional biopsy of the lump if its clinically significant. BRCA mutation should also be checked.
I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
