What are the chances of survival for a person who is suffering rectal cancer?

Depends on Stage: The staging of rectal cancer is based on ct scanning, endorectal ultrasound, and preop lab testing. Sometimes the staging is determined after surgery depending on your presentation. Stage i is the best survival and stage IV is the worst. Stage ii and stage iii cancers often require chemotherapy to improve survival.

Depends upon stage: The cure rate for early stage rectal cancers is over 90% with surgery alone, but the survival rate for advanced rectal cancers is much, much lower.
