Tell me about intron a (interferon alfa 2b) cancer related immune agent?

Interferon: Intron a (interferon alfa 2b) is the trade name for interferon alpha. Not used as much as in the past, but still can be used for high risk melanoma, rarely for some myeloproliferative neoplasia situations and renal cell cancers. Most common use is in hepatitis c. Interferon is a natural substance made by lymphoid cells in response to viral and other illnesses.
