At least 2x average human strength and speed. (Despite being able to lob double decker buses.)No weak spots to concussive, blunt, or sharp force trauma.Chemo therapy causes your body to basically age to near-death before becoming any better. Treating yourself with it constantly could prove fatal. Judging by the title, POST-Post apocalyptic. I'm assuming that chemo would be scare, and I'm being generous with that amount, so the character would likely die a quick death.Again, these are just concerns I'm voicing because I'm noticing a character who will be quantifiably superior to everyone else in every way.
I said that it is a DECRASE. No more double-decker throwing, no more full-body diamond armor - and even if there is some plating, a bullet would go through with ease.
What kind of powers do we have for now? Electrokinesis, acoustokinesis and expert gunslinging. All of those prove to be fatal, as he wont have enough diamond plating to protect every inch of his body, and he still will be flesh-and-bone somewhere, thus, internal bleeding from acoustic attacks will kill him and electricity will still find a way around the diamond insulation. Plus, he isnt fast enough to dodge bullets either.
As for chemotherapy, i may as well include a drug producing organ. When you have an "iron" stomach, aquiring the needed components can be done through devouring the evolved fauna/flora, hence why he has cancer in the first place. Plus, there are certain ways to decrease the damage. I dont fully understand how it is achived yet, so i will refrain from further explanations, but if you feel like it, you're free to join me in my Wikipedia-reading trip, there is some info there.
