How to prevent Cancer Cervix
MOST IMPORTANT METHOD FOR MOST IMPORTANT METHOD FOR PREVENTION AND EARLY DETECTION PREVENTION AND EARLY DETECTION OF CANCER CERVIX IS BY OF CANCER CERVIX IS BY CERVICAL SCREENING WITH PAP’S CERVICAL SCREENING WITH PAP’S SMEAR SMEAR
Pap smear - guidelines Target group - All women aged yrs who have ever had sex Timing of Initial Screening - Initial screening at age of 21 years or within 3 years of sexual activity Initial screening at age of 21 years or within 3 years of sexual activity Screening interval – Screening interval – Yearly till the age of 30 then every 2 to 3 yearly if test results have been normal for 3 years in a row. Yearly till the age of 30 then every 2 to 3 yearly if test results have been normal for 3 years in a row. When to End Screening - After 70 yrs if test results have been normal for at least 3 years in a row and no result has been abnormal in the last 10 years. - After 70 yrs if test results have been normal for at least 3 years in a row and no result has been abnormal in the last 10 years. - Post Hysterectomy - Post Hysterectomy
For women at high risk of HPV, the HPV test can be done at the same time as a Pap test. Screening Test for HPV
Colposcopy Colposcopy is often done if results of a Papanicolaou (Pap) test are abnormal. For colposcopy, cervix is inspected for signs of cancer. Often, a sample of tissue is removed for examination (biopsy). Colposcopy alone (without biopsy) is painless and thus requires no anesthetic.
Treatment The main treatment of gynecologic cancer is surgical removal of the tumor. Surgery may be followed by radiation therapy or chemotherapy.
Prognosis Prognosis depends on the stage of the cancer. With treatment, 80 to 90% of women with stage I cancer and 50 to 65% of those with stage II cancer are alive 5 years after diagnosis.

Cancer Cervix IS PREVENTABLE, IF Detected EARLY!!!!!!!!! THANK YOU
HPV is a necessary cause of cervical cancer – 99.7% Induction of neutralising antibodies by vaccination is critical for protection HPV 16 & 18 cause ~75% * of cervical cancer cases while HPV 6 & 11 cause ~90% genital warts 27% of the world burden of Cervical Cancer is seen in India. Every 7 minutes a woman dies in India due to cervical cancer Cervical Cancer is usually diagnosed in late stages in India. Cervical cancer screening is recommended in women >30yrs Vaccination between 9-26yrs can be an effective strategy to help reduce this huge disease burden. * India
