Cervical cancer occurs when the cells in a woman's-cervix, which connects the uterus-and vagina, change. This cancer can affect the deeper tissues of their-cervix and spread to other parts of their body (metastasize), often to the lungs, liver, bladder, vagina, and rectum.Most cases of cervical cancer are caused by infection with the human papillomavirus (HPV), which can be prevented with a vaccine. Cervical cancer grows slowly, so it usually has time to be detected and treated before it causes serious problems. It can be detected in time through Pap tests. Apart from this, there are also some symptoms, by recognizing which you can prevent cancer in time.
