12 cancer screening tests India doctors recommend

4. Oral cancer screening: visual oral examination

Oral cancer screening is especially important in India because of higher prevalence linked to tobacco, areca (betel) nut chewing and smokeless tobacco use. A simple visual oral examination by a trained clinician can find white or red patches, ulcers, or suspicious lumps early. Doctors recommend regular checks for anyone who uses tobacco or betel products, with opportunistic screening during dental or primary-care visits. Community screening camps and dental clinics may offer examinations free or at low cost. If a lesion is suspicious, a biopsy or specialist referral follows.
