Cervical tumors refer to abnormal growths that occur in the cervix, the lower part of the uterus that connects to the vagina. These tumors can be benign (non-cancerous) or malignant (cancerous). The most common type of cervical cancer is squamous cell carcinoma, which arises from the squamous cells lining the cervix. Another type is adenocarcinoma, which originates from glandular cells.
