TOP HIP HOP STAR WAS DIAGNOSED WITH LIFE THREATENING CANCER . . . IS NOT EXPECTED TO BEAT IT!!!!

SAD news. Shawn Jay from Atlanta's FIELD MOB was just notified by physicians that he has CANCER!!!

According to Shawn, he had a similar cancer scare last year and the doctors now believe he OFFICIALLY has cancer. He's going in for testing today to see how AGGRESSIVE the cancer is . . . and whether or not his diagnosis is TERMINAL.

We're all going to say a prayer for him.
