The 30-year-old actress announced she was diagnosed in September 2014, and is undergoing chemotherapy as treatment. Rodriguez broke the news on her new ChemoCouture website, a blog dedicated to her journey with the disease.
"On September 24, 2014 at age 30, I was diagnosed with stage 2B ductal carcinoma: in-situ and invasive," she wrote. "Now as far as cancer goes, I have the Cadillac of tumors. It's slow growing, highly treatable and not really interested in spreading. My doctor calls it an 'old lady cancer.'"
