Scalise said he has begun treatment, which will continue for "several months."   

"I expect to work through this period and intend to return to Washington, continuing my work as Majority Leader and serving the people of Louisiana's First Congressional District," Scalise wrote. "I am incredibly grateful we were able to detect this early and that this cancer is treatable.
