Lump at Underarm After Breast Augmentation

You should always check with your PS when you see lumps or discolorations.  An examination is necessary to make sure it isn't anything serious or a hematoma. 

A transaxillary lump after a breast augmentation may be a swollen lymph node, may be a hematoma or seroma or even the soft tissue that is sutured together. Check this out with your surgeon.

I have to agree with Dr. Yuan. It is impossible for anyone to tell definitively without examining you. I would call my surgeon and ask him his opinion. I'm sure he would be glad to discuss this with you.

Your surgeon knows what transpired at surgery. Unless someone can exam you, any answer will only be speculation. Ask your surgeon to explain what he thinks it is.

Hi.
This little lump does not sound worrisome.  You most likely have a small hematoma (collection of blood) after breast implants and this should go away in a few weeks.

Without an examination it is difficult to know. Your symptoms sound most consistent with a small collection of blood (hematoma). It usually goes away on it's own. If it is red and hot, an infection is a possibilty, but less likely. Ask your physician.
