The study, published in the Lancet medical journal, observed that two strands of HPV virus that are mainly responsible for cervical cancer fell 83 per cent in girls aged 13 to 19 after five to eight years of vaccination.
Cervical cancer is most common in women aged 30 to 35 years. However, the precancerous stage is detectable in the 5-10 years before this, when up to a third of women fail to attend for their smear test.
Studies show that women with three or more full-term pregnancies are at an increased risk of cervical cancer. Women who deliver before the age of 17 are also twice more likely to be affected than those who deliver after 25 years of age.
World Cancer Day: Patients with cervical cancer, who continue their pregnancy, should be closely monitored until delivery. Advanced medical science has enabled gynecologists to remove cancerous cervix while preserving the womb.
