Hi,
Thank you for posting your query.
I have noted your father's symptoms and diagnosis.
Pituitary
adenoma needs surgery for treatment, as there are no medicines to reduce it completely. Also, this
tumor may press on the optic nerves resulting in greater loss of vision.
The surgery would be done by a neurosurgeon, and is mostly done through the nose.
The cost differs among different centres in India and may range from 5000 to 10000 USD.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
