HPV Vaccine: Your Shield Against Cervical Cancer

What is HPV?



Human Papillomavirus (HPV) is the most common sexually transmitted infection. There are over 100 types, and some can cause cervical cancer and other cancers.

HPV and Cancer Risk



High-Risk HPV Types:
  • Cause 99% of cervical cancers

  • Also cause vaginal, vulvar, anal, and throat cancers

  • Types 16 and 18 cause 70% of cervical cancers


  • Low-Risk Types:
  • Cause genital warts

  • Not cancer-causing


  • In India:
  • Cervical cancer is the 2nd most common cancer in women

  • 1 woman dies every 8 minutes from cervical cancer

  • Most cases are preventable with HPV vaccine
