Sen. Arlen Specter has a book out titled “Never Give In: Battling Cancer in the Senate.”

The Republican has a new fight on his hands.

The cancer is back.

Specter’s doctors yesterday announced he has suffered a recurrence of Hodgin’s disease, which affects the lymph system. Specter successfully battled the disease three years ago.

Specter is 78. He has beaten cancer once. He wasn’t stopped by removal of a benign brain tumor in 1993, which recurred in 1996. He also underwent coronary bypass surgery in 1998.

He is vowing to keep working while he undergoes chemotherapy for the latest cancer occurrence.

He is amazingly active, and plays squash every day.

Don’t bet against him. Our thoughts are with you, senator.
