What causes cervical cancer?

Most cervical cancer cases are apparently caused by strains of the human papillomavirus (HPV), a sexually transmitted infection. You can limit your chances of getting HPV through having fewer sexual partners, and fewer partners who have had many other partners. Starting having sex later in life also limits your chances of developing cervical cancer. The cervix of a young girl is more susceptible to damage from sex. Smoking also has some connection to cervical cancer, but it is not clearly understood. Smokers do have an increased chance of getting cervical cancer. There may also be a link between cervical cancer and receiving estrogen treatment for menopause. In the past, the hormone estrogren was used alone. Now it is combined with progesterone. When used alone, estrogren increases the risk of cancer.
