After pregnancy, due to the high level of estrogen itself, it can lead to the enlargement of bilateral breast glands. If you feel a fleshy lump in your armpit, the first thing to consider is whether you have a parammary gland, because hormonal stimulation and the parammary gland itself also has glands that can lead to its own enlargement. If this is the case, you can go to the ultrasound department of the hospital to have a bilateral underarm ultrasound to see if it is breast tissue to find out if it is a parametrial gland. It is possible that the lymph nodes are enlarged due to inflammation of the bilateral mammary glands, but it is necessary to find out whether it is caused by inflammation or not, and ultrasound can be done to see the structure of the lymph nodes and how the nodes are gated. The disease should be diagnosed at an early stage so as to avoid delay.
