Your friend has Nasal Carcinoma.
He will require a CT scan
of the Nasal Sinuses
and Facial bones to see the extent of involvement of the underlying structures.
The definitive treatment will be surgical excision of the involved structure.
Post operatively, chemotherapy
and or radiotherapy will be required as indicated.
Whether it can be cured or not depends on the stage of the Tumour. If its early stage and not spread to surrounding structures, it can be controlled to a large extent.
Hope this answers your query
