Jenna Fischer, Pam from 'The Office,' reveals a private cancer battle that is over — for now. She was diagnosed with triple-positive breast cancer last year.

The American version of the series "The Office" is still considered one of the best comedy productions of all time. For years, Pam Beesly, played by Jenna Fischer, greeted clients in the office. The actress recently shared her story of battling illness with her fans online.

Fischer said she was diagnosed with an “aggressive” but treatable form of breast cancer, and has recovered after treatments, including chemotherapy and radiation.
