Mouth (oral) cancer is classified under head-and-neck malignancies and is usually managed within that broader specialty.
Key points drawn from recent Indian cancer statistics and clinical guidance include:

Who is most at risk?
• Disease is most frequently diagnosed after age 40, and men are affected more often than women.
• In the current year alone, India has recorded roughly 77,000 new oral-cancer cases and more than 52,000 deaths.

Why early detection matters
• Tumors are commonly found only after they have spread to the neck’s lymph nodes, which significantly reduces survival chances.
• When discovered at an early stage, cure rates rise dramatically.

Principal sites inside the mouth
1 Lips
2 Tongue
3 Inner cheek (buccal mucosa)
4 Gums
5 Floor of mouth and other lower-oral regions

Typical warning signs
• Persistent ulcers or sores that do not heal
• Red, white, or mixed patches on the oral lining
• Unexplained lumps, bleeding, numbness, or difficulty chewing and swallowing

Recommended preventive steps
• Schedule a professional oral examination at least twice a year, or sooner if any of the above symptoms appear.
• Avoid known risk factors such as tobacco (smoked or chewed), excessive alcohol, and betel-nut products; protect lips from prolonged sun exposure; consider HPV vaccination where appropriate.
