The causes of breast shape change include genetic factors and pathological factors such as breast cancer, breast hyperplasia, trauma, etc. The treatment includes medication and surgery. 1. Genetic factors: For breast deformity caused by genetic factors, no special treatment is needed at this time, and those with high cosmetic requirements can be treated with plastic surgery. 2. Breast cancer: If the abnormal proliferation of breast cells is triggered by various external factors, which leads to the change of the nature of the breast, then surgical treatment such as radical mastectomy can be given. 3. Breast hyperplasia: for breast deformation caused by breast hyperplasia, Tamoxifen, Finasteride and other drugs such as anti-androgen treatment can be given at this time. 4. Trauma: If breast deformation is caused by trauma, then surgical treatment such as mammoplasty can be given. Lastly, please consult your doctor in time for breast shape changes and follow the doctor’s instructions for the above medications.
