 Happy anniversary, KBLA! Moments like hearing my cat purr good morning mean a lot to me. But after being diagnosed with metastatic breast cancer, or MBC, which is breast cancer that is spread to other parts of the body, they mean even more. I take Ibrance Pelviciclib. Ibrance 125 milligram tablets with an aromatase inhibitor is for adults with HR positive HER2 negative MBC as the first hormonal-based therapy. Ask your doctor about Ibrance and visit Ibrance.com.
