Sexually transmitted diseases can also lead to cervical cancer especially HPV which is the human papiloma Virus. It is transmitted sexually and you show no symptoms until you go have a pap smear and the doctor informs you that you results were abnormal. It is passed on unknowingly during sexual intercourse. If left untreated it will become cervical cancer. if caught quickly, the doctors will perform a biopsy which usually show abnormal cells on your cervix. The cells are removed normally as an outpatient procedure in the doctors office ( usually a specialist, like an OB GYN) By shaving a layer off your cervix, thereby removing the pre-cancerous cells. If allowed to stay they will mutate and multiply and become cancerous, which leads to more serious interventions. Most Doctors offices now offer an HPV Vaccine, which is a three shot system over the course of a year to protect you from HPV which is the leading cause of cervical cancer in women.
HPV has nothing to do with HIV, the virus that causes AIDS. There are 46 genetic types of HPV, but not all are dangerous. Only certain types of HPV, which can be transmitted from one person to another during sexual contact, increase the risk of cell dysplasia (abnormal cell growth) and/or progression to cervical cancer.
Finally we don't know exactly what causes cervical cancer, only the things that seem to increase your risks, mainly Medical history and lifestyle - especially sexual habits - play a role in a woman's chances of developing cervical cancer.
