House Majority Leader Steve Scalise said on Tuesday that he has been diagnosed with “a very treatable” blood cancer and is currently undergoing treatment.

“After a few days of not feeling like myself this past week, I had some blood work done. The results uncovered some irregularities and after undergoing additional tests, I was diagnosed with Multiple Myeloma, a very treatable blood cancer,” Scalise (R-La.) said in a statement.

Scalise added that the cancer was detected early and he expects the treatment will continue “for the next several months,” but that he intends to return to Washington, D.C. The House is scheduled to return on Sept. 12 after being out of town since late July.
