<s>[INST] I'm 49 years old, 5'2". I am a breast cancer survior in the right breast, thru a lumpecotmy.  I now have a lump under my right arm.  After a mammogram (which could not reach the spot) and a sonogram.  The radiologist says it's a swollen liagment.  Should I call my surgeon or just go with this answer? [/INST] if the lump is under your armpit, then it goes more in favour of metastatic deposit, considering you are a known case of ca breast. it's important to look for any other lumps. since the radiologist says it's a swelling from tendons, u don't have to worry much, but to be sure get your surgeon to have a look at it and probably get an FNAC to rule out malignancy. </s>
