Hello dear
I understand your concern
Yellowish brown discharge could be a normal discharge,
fibrocystic disease,
thyroid disorder, hormonal medicine, ductal papilloma, infection.
For safer side, consult the surgeon and undergo breast examination, and investigations like
Laboratory analysis of the discharge,
Mammogram and/or
ultrasound, FNAC,
Surgical excision and analysis if needed.
Treatment will depend on the specific cause.
Meanwhile avoid stress, take healthy diet, do regular exercise, maintain hygiene and drink plenty of water
Hope this may help you
Contact HCM for further health query
Best regards
Dr. Sagar
