Cervical cancer is characterized by the abnormal growth of cancerous cells in the tissues of the cervix. The disease manifests as either squamous cell carcinoma or adenocarcinoma. Squamous cell carcinoma originates in the lining of the cervix, while adenocarcinoma arises in cervical cells filled with mucus and other fluids. Squamous cell carcinoma is the dominant subtype of cervical cancer, affecting about nine out of 10 cervical cancer patients. The disease is asymptomatic in the early stages. The signs and symptoms in the late stages include abnormal vaginal bleeding, unusual vaginal discharge, and pelvic pain. HPV infections are the most common cause of cervical cancer, globally. The incidence of the disease is higher in less developed regions such as Africa, Latin America, and the Caribbean compared to North America and Oceania.
