Anatomically, female's internal reproductive organs are the vagina, uterus, fallopian tubes, cervix, and ovary. The main external structures of the female reproductive system include labia majora, labia minora, clitoris, Bartholin's glands. Cervical cancer is the cancer of cervix.
In the beginning, the cancer is diagnosed only by viewing cervical cells under a microscope. Lymph nodes are not involved at this stage. In Stage IB, the doctor can see the cancerous cells, but the cancer is found only in the cervix. In later stages, it spreads beyond the original site.
