India rank's no. 1 in cancer cervix, this is largely because we believe that leucorrhoea (white discharge per vagina) is normal to occur. This leucorrhoea is primarily because of a variety of genital infections like candidiasis, trichomoniasis, vaginosis etc. These vaginal infections render the genital tract susceptible to HPV (Human Papilloma Virus) infection. When we come across HPV, usually 80% of HPV infections are cleared off by our immunity. But if our immunity is hampered due to these vaginal infections, promiscuity, early age at intercourse, smoking etc, we tend to harbor this organism in our cervical cells (cells the f mouth of uterus). There HPV causes sequence of changes ranging from ASCOUS, AGOUS, CIN1, CIN2, CIN3, carcinoma in situ to florid Cancer cervix (cancer of mouth of uterus). These changes take about 10-12 years before conversion to florid cancer giving us a window for catching the diseases in its infancy.
