What is Gynecological Carcinosarcoma?


Gynecological Carcinosarcoma (GCS) is a rare and aggressive cancer found primarily in the ovaries and uterus and can also originate in the fallopian tubes and vagina. GCS, is also known as MMMT or malignant mixed Müllerian tumor. Carcinosarcoma is unique in that it contains two types of cells; carcinomatous (epithelial tissue) and sarcomatous (connective tissue). GCS is rare. Fewer than 1,000 cases of GCS are diagnosed each year. Because carcinosarcoma is so rare, there has been limited research or clinical trials that focus on GCS. Unfortunately, this is where the cures will be found. Little or no research results in no cures or effective treatments for us. In order for us to have a fighting chance, we must aggressively support new and ongoing research so that Not One More Woman Will Die from this rotten cancer. You can read more about GCS here.
