Missouri Senator Claire McCaskill has declared that she is suffering from breast cancer. She has also revealed she expects “a full recovery.”

The revelation came through a blog written by the 62-year-old American politician. She wrote she would be in St. Louis for treatment for the next three weeks. “During this time my staff will continue to assist Missourians and I will be posting on my Senate website (McCaskill.senate.gov) how I would have voted on any matters that come before the Senate during my absence—which I’ll also enter into the Congressional record,” she wrote.

According to McCaskill, she “very recently” came to know about her cancer during a regular mammogram. While she admits it is “a little scary” to have been diagnosed with cancer, her prognosis is good.

McCaskill may take inspirations from a number of fellow senators, who are cancer survivors. Arizona Senator John McCain, North Dakota Senator Heidi Heitkamp, Maine Senator Angus King and Florida Senator Bill Nelson have all survived cancer.

Best wishes poured in for the US politician from both Democrats and Republicans.

Heitkamp wished her luck in her battle against cancer. “You’re a fighter and I’m cheering for you all the way,” the cancer survivor tweeted. South Carolina Senator Lindsey Graham prayed for a “quick and speedy recovery.”

The senator was first elected in 2006, and she also won reelection in 2012, when she beat former Republican Rep. Todd Akin. According to Politico, McCaskill has been strongly advocating for reforming how cases of sexual abuses are dealt with in the military.

McCaskill, who backed Barack Obama during his first presidential campaign in 2008, has been a strong supporter of Hillary Clinton’s presidential campaign.

Clinton was quick to motivate the Democrat lawmaker through one of her personally signed tweets. “I’m in your corner,” she wrote.
