Diagnosed with axillary breast tissue....doesn't seem right

Leea525

A few years ago, I developed a lump under my right arm. It was soft and seemed like an enlarged lymph node. An ultrasound concluded it was breast tissue. It has changed shape in the last couple of years and started to throb at random intervals. I have since seen my doctor twice and also saw a physicians assistant in the breast clinic and again was told it is just accessory breast tissue. I have never been pregnant and I am 45 years old so this sudden growth seems strange to me. I do have saline implants so I wonder if that could have caused additional growth of tissue in that area. Has anyone else ever had this issue
