Baton Rouge rapper Lil' Boosie announced Wednesdaythat he has kidney cancer.

"I need all my fans to pray for me Doctor just told me I have cancer on my kidneys prayer is power that's why I'm letting the world know prayfaboosie," he wrote on his Instagram page.

According to TMZ.com, the caption on the photo has since been removed because the rapper's team wasn't pleased he revealed his condition to the public.

This past June, Boosie sat down with Rolling Stone for a far-reaching interview that touches on music, life in prison (he was released from Angola last year after serving time for marijuana possession), fellow Louisiana rapper C-Murder, Ferguson, Louisiana, Baton Rouge and much more.
