What Every Woman Should Know About Cervical Cancer
1. What are the key causes of cervical cancer?
More than 90% of cervical cancers are caused by an infection with Human Papilloma Virus (HPV). HPV is divided into high-risk strains and low risk strains. Only the high-risk strains are responsible for causing cervical cancers.
2. Can you explain the importance of regular cervical cancer screenings and the recommended age at which women should begin these screenings?
It takes many years from the time of HPV infection till the development of cervical cancers. The pre-cancerous changes to the cervix also known as cervical intraepithelial neoplasia (CIN) is asymptomatic and very treatable with a high chance of cure. Hence it is important to screen regularly as there are no symptoms in the pre-cancerous stage. Screening for cervical cancer should begin from 25 years in a woman who has previously engaged in sexual intercourse.

For cervical cancer screening, PAP smear tests every 3 years is performed from age 25-29 and a HPV test is performed every 5 years from 30 years onwards.
4. Are there any recent advancements in cervical cancer screening technologies that women should be aware of, and how might these impact the accuracy and convenience of screenings?
