What would be an actual real life mechanisms of an accelerated healing factor?

I'm writing a rough sketch for a book about a world where people sorta violently and suddenly get barely working superpowers. That is every time each person uses their power they run the risk of killing themselves. (I already almost set up the world with powers like invisibility, intangibility, super speed, their drawbacks and all.)

Now I'm struggling to flesh out a mad psycho character with an accelerated healing factor. This world is very much grounded in reality. Points to keep in mind:

1. Using the healing factor also (ironically) runs the chance of potentially killing him every single time
2. The healing factor must have a major physical drawback/kink
3. He can only barely heal from bullet wounds, cuts and broken or dislocated bones. But he still keeps on fighting.

Really need help, 'cause I have this whole world setup and he's the guy that makes the readers realize how dangerous everyday life in this world can be.

EDIT Form the answers I got,the character is a man of average build. When he is injured his body uses every resource it has at hand and heals him but leaves him frail and at the point of starvation. The newly healed parts carry the risk of potentially becoming cancerous. The speed at which the repair is done causes a lot of discharge in the form of heat,requiring him to cool down himself.

(For reference,in my world the one of the lead characters with superspeed has a well developed and more branched circulatory system concentrated in and around his legs. The muscle cells in his legs have a new type of protein that causes them to contract way more faster in response to a signal. This only pertains to his legs. He can only run at about 101m/hr or 180km/s and that too for barely a 1 minute. But he only only run in one direction,he cannot change directions while running and he only has a normal human level perception of time. Running at high speeds causes his bones to have multiple severe micro fractures and he can't breathe properly while running. His whole body is hurt from the air resistance as well,he also has to build up speed and constantly hits into thing injuring him. And he suffers from the effects of inertia. He constantly has to see his doctor and running at high speeds for even once in a day leaves him sore and unable to walk for 2-3 days. He also has to eat a lot for the required energy and running leaves him on the brink of death )

The mad psycho character needs to heal bullet wounds,cuts and broken or dislocated bones in under a minute. The healing does not have to proper as well. And no stem cells and definitely no nanobots. The power is a mix of torture,stress,trauma and mutation
