Katie Couric, who has been supporting cancer research for over two decades, revealed that she has also been diagnosed with the dreaded disease.

After losing her husband and sister to cancer, Couric must face her battle after learning that she also has the same disease. The former "Today" co-host spoke about her diagnosis on Wednesday through an Instagram post, saying that she has breast cancer.

She revealed that she was diagnosed in June, becoming the latest member to face the dreaded condition after her husband, Jay, was diagnosed with colon cancer , and her sister, Emily, with pancreatic cancer. 

Couric shared in-depth details of her health through an essay on her website titled "Why NOT Me?"

"I had practically become an expert on colon and pancreatic cancers, but no one in my family had ever had breast cancer. During that 24-hour whirlwind, I found out that 85 percent of the 264,000 American women who are diagnosed every year in this country have no family history. I clearly had a lot to learn," she acknowledges. 

Couric reminded everyone to get their annual mammogram and undergo additional screening if needed.
