Mercedes Castiel, MD, FACOG, FRCS(C)

I am a board-certified gynecologist with a multifaceted clinical practice. I provide general gynecologic care to cancer patients at Memorial Sloan Kettering, whether they are in the midst of therapy or have already completed their treatment. I also care for women who are at high risk for gynecologic cancers due to their personal or family histories.

After cancer treatment many women have acute gynecologic needs and other survivorship issues. For these women I developed a program that helps them manage menopausal symptoms, addresses their hereditary risk, refers them for screening evaluations, and promotes their sexual health during and after treatment. I also discuss fertility options for those women who may become menopausal as a result of treatment, or for whom pregnancy is contraindicated after treatment.
