Hi.
Thanks for your query and an elucidate history.
A small lump in the armpit, which is small and just tender and can be moved a bit, without
redness and the area is warm can be due to:
A Sebaceous cyst just infected.
Or a
Lymph node.
This can be confirmed by a physical examination by a
General Surgeon and
ultrasonography and guided FNAC.
If this is a sebaceous cyst , get it removed.
If a lymph node , then a course of 3 weeks of antibiotics and anti-inflammatory medicines will solve this.
Since you are a female patient , Excision
biopsy is a must for the following reasons
- You get rid of the swelling
-you get a diagnosis by histo-pathological examination.
Also needed is a physical examination of the breasts to see whether there is a cancer ion the breast. Also go for FNAC, mammography
