What are some common slow growing lymphomas in young men and how long can they take to fully manifest? how is cure rate for these particular lymphomas

Rare in 21 year olds: All lymphomas are rare in 21 year olds; there are no common ones. In general, the indolent lymphomas can grow very slowly with a natural history over years. These may not need treatment right away, and usually shrink very rapidly with mild chemotherapy and/or low dose radiation, but are difficult to cure and often return months to years later. These low grade disease are rare in young men.
