I am sorry for the delay in my reply. I was called for an emergency minor surgical procedure. I apologize for your wait.
You would require hormonal assessment and an ultrasound for the evaluation as the first step.
Gynecomastia refers to a benign enlargement of the male breast resulting from the proliferation of the glandular tissue of the breast. This may be considered as a physiologic situation: (transient gynecomastia of the newborn caused by maternal or placental estrogens and, pubertal gynecomastia observed in 40% of adolescent boys, resolving by 18 years of age are the other situations); gynecomastia that occasionally occurs in older adult men (resulting from changes in estrogen and androgen metabolism).
True gynecomastia must be distinguished from enlargement of breast tissue secondary to lipomastia, in which enlargement is caused by excess adipose (fat) tissue. Mammography may distinguish between these two entities if the physical examination is indeterminate. Gynecomastia occurs as concentric, palpable glandular tissue beneath the areola that is not fixed to underlying structures.
For cautionary reasons following should be done;
1) Liver function tests
2) Examination of testes and prostate
3) Hormone estimations; prolactin, estrogen, and thyroid.
You may need minor surgery if the size is not reducing in the last 1-2 years.
I am sorry again for your waiting.
I wish your symptoms resolve soon.
I would be happy to assist you further if you need any more information.
