Cervical cancer arises from the cervix and has the tendency to spread to different genital organs. It is one of the deadliest cancers among women. Cervix is the lower part of the uterus that opens in the vagina. Most cervical cancer is due a virus called human papillomavirus (HPV), which also causes genital warts.
In an international study, it was reported that although there are 200 types of HPV. Two human papillomavirus, HPV 16 and HPV 18 cause 71% of cervical cancers. Both of these are preventable by vaccination, but there are six other HPVs that cause it, including HPV 31, HPV 33 and HPV 45.
Most of the time women clear HPV infection on their own. However, if it stays for longer than a few years they are more likely to become cancerous. HPV is a sexually transmitted disease which one can get from oral, anal or vaginal sex.
Also, women are exposed to diethylstilbestrol (DES) while their mothers were pregnant are at higher risk of developing cervical cancer. DES is linked with causing abnormal cells in cervix and vagina.
