Cancer of the fallopian tubes is an abnormal growth of malignant cells in one or both of the fallopian tubes. There are several different types of fallopian tube cancer including:
- Papillary serous adenocarcinomas. More than 95 percent of fallopian tube cancers are papillary serous adenocarcinomas. This type of cancer grows from the cells lining the fallopian tubes. When the cells begin to divide abnormally and invade other organs or spread to other parts of the body, tumors may form.
- Primary fallopian tube cancer. Primary fallopian tube cancer is extremely rare, representing approximately 1 percent of all gynecologic cancers.
- Sarcomas (leiomyosarcomas). Occasionally, tumors called sarcomas (leiomyosarcomas) may form from smooth muscle in the fallopian tubes. Tumors can also form on other cells that line the fallopian tubes and are called transitional cell carcinomas.
