Yet another name that book.

[chrisc1509]

Please can you help me identify this sci fi book that I read 18 years ago. An overweight scooter riding petty criminal was caught and imprisoned, but sadidistic prison treatment buffed him up. Cancerous mutants called voors were involved, as were time and space portals.
