How do dense breasts influence breast cancer risk?

(Julia Landwehr/ Health) –– Katie Couric announced Wednesday that she was diagnosed with breast cancer earlier this year, and had just finished her final round of radiation for the disease this week.

“Every two minutes, a woman is diagnosed with breast cancer in the United States,” Couric, 65, wrote on Instagram. “On June 21st, I became one of them.”

Couric, whose first husband died from colon cancer in 1998, has long been a proponent of cancer research and screenings—the former Today co-host even broadcasted her own colonoscopy to raise awareness for the disease.

Now, with her own cancer diagnosis, Couric wrote that she wanted to share her experience to encourage others to stay on top of their recommended cancer screenings—particularly if they have certain risk factors.
