VH1 Star Real -- My Cancer is Almost Gone ... It's a Miracle!

The star of VH1's "Real Chance of Love" went under the knife Wednesday night to remove huge chunks of cancer from his colon ... and TMZ has learned the operation was a guarded success.

A rep for Ahmad Givens a.k.a. Real tells us ... when doctors began operating Wednesday night they thought he had colon cancer. Turns out it was stage 4 rectal cancer and they were able to remove it all.

But there was another problem. Real also had 7 tumors in his liver. Doctors removed all but a small portion that was deep in the liver. The docs are hopeful ... with radiation they can eliminate the remnants of his liver cancer.

Bottom line .... going into the surgery, it looked like Real was a goner, but now he has a good, fighting chance of survival.
