That is my point. And the suit didn't just grew into his wounds. It broke down his heart into base components, along with some other organs. He's effectively a living suit.

Does he need to eat or produce waste? We don't know at this point. Even the N1s were symbiotic, as Prophet said. Maybe not to the extent N2 did with Alcatraz. But give it time, they'd no doubt punch through that silly mesh underlay Prophet was wearing under his suit. The fact remains, you can't remove it in the end.
