VIA, or visual inspection with acetic acid, is a low-cost cervical cancer screening method that can identify precancerous lesions. It involves visualizing the cervix after applying acetic acid to enhance abnormalities. Studies have shown VIA to have a sensitivity of 65-96% and specificity of 64-98% compared to other screening methods. VIA provides immediate results, does not require specialized equipment or training, and can be performed as part of mass cancer screening programs in developing countries.
