High incidences of cervical cancer are reported mainly from rural and in underprivileged populations in urban areas.  CFI regularly holds cervical cancer screening field clinics on voluntary basis in rural and urban slum populations. This programme that began in 2004 has screened more than 9000 women in the districts of south 24 parganas, Nadia and Kolkata in the state of West Bengal. Each screening clinic is held in the village / slums where women are first made aware of the disease through innovative communication material developed in-house at CFI. After thorough medical examination and documentation, cervical screening is done by visual inspection of the uterine cervix after the application of 3-5% acetic acid (VIA) or Lugol’s Iodine (VILI). Screen positive women are examined by colposcope and biopsy taken for histological confirmation of the lesion. Cryotherapy treatment and follow-up is provided to CIN positive women in the field clinics. In cases where excision by LLETZ, laser cone or knife cone procedures are required and the invasive cancer cases detected during the screening are referred to collaborating hospitals in Kolkata.
