Senate Majority Whip Dick Durbin (D-Ill.), who recently underwent successful surgery to have a small gastrointestinal stromal tumor removed, does not have cancer, the results of a biopsy confirmed.

“The full biopsy of the tumor removed from Sen. Durbin’s stomach on Aug. 12 has been completed and showed no signs of cancer,” spokesman Joe Shoemaker said in a statement. “Doctors say no further treatment is expected.”

The surgery to remove the noncancerous tumor took place at the University of Chicago Medical Center. Durbin, 65, was released Aug. 13 and quickly launched into work mode in his home state with public events and campaign stops for Democratic Senate nominee Alexi Giannoulias.

Speaking at a press conference in Springfield last week, Durbin touched on his hospital experience and noted that it reminded him “how many millions of Americans wouldn’t have the opportunity I had because of our medical care system in this country.”

“And that’s why when I look back at this, no apologies on health care reform,” he said. “None.”
