According to Statistic of India has one of the highest oral cancer burdens in the world. It contributes a large share of global cases thanks largely to tobacco (smoked and smokeless) and areca nut use. According to one recent national source, there are approximately 77,000 new oral cancer cases in India annually, with men affected more than women.
Oral cancer constitutes a major proportion of all cancers in India — around 11–12% of all male cancers and significant among females too.
A government report noted oral cancer incidence in Karnataka is around 12 per 100,000 people, higher than the national average for oral and related cancers.
Hospital registry data (from the Kidwai Memorial Institute) historically showed that in Karnataka, about 24% of all cancer cases are related to tobacco, and oral cancer is a prominent component.
Karnataka’s broader cancer data (not limited to oral cancer) suggests 26,516 cancer deaths overall in recent estimates, a portion of which are due to oral cancers — especially those linked to tobacco use.
Statistic
| India (Approx.) | Karnataka (Approx.) | |
|---|---|---|
| Oral cancer new cases per year | ~77,000 | Not separately reported statewide, but incidence ~12/100,000 |
| Oral cancer deaths per year | ~52,000 | Part of ~26,516 total cancer deaths (oral cancer is a significant contributor) |
| Major cause | Tobacco (smoked & smokeless) | Tobacco (especially smokeless) |
Deaths (Mortality)
There are about 52,000 deaths annually in India due to oral cancer.
Oral cancer accounts for a large share of tobacco-related cancer deaths nationwide since it is often detected late.
Mouth Cancer: Causes, Symptoms, Diagnosis, and Treatment
Mouth cancer, also known as oral cancer, is a serious health condition that affects thousands of people every year. It can develop in any part of the mouth, including the lips, tongue, cheeks, gums, floor of the mouth, and roof of the mouth. Early detection and timely treatment can significantly improve survival rates and quality of life.
What is Mouth Cancer
Mouth cancer is a type of cancer that occurs when abnormal cells grow uncontrollably in the tissues of the oral cavity. It is one of the most common cancers in India, especially among people who use tobacco or consume alcohol regularly.
Types of Mouth Cancer
1. Squamous Cell Carcinoma (SCC)
Starts from the flat cells lining the mouth
Affects tongue, cheeks, gums, floor of mouth, lips
Strongly linked to tobacco, gutkha, pan, smoking, alcohol
2. Verrucous Carcinoma
A slow-growing variant of squamous cell carcinoma
Looks like a warty or cauliflower-like growth
Rarely spreads to lymph nodes
Common in chronic tobacco chewers
3. Adenocarcinoma
Arises from minor salivary glands
Usually seen in palate or inner cheeks
Less common than SCC
4. Mucoepidermoid Carcinoma
Cancer of salivary gland tissue
Can occur inside the mouth or jaw
Seen in both adults and children
5. Lymphoma
Cancer of the immune system
May appear as a soft swelling in tonsils or floor of mouth
6. Melanoma (Oral Melanoma)
Rare but very aggressive
Appears as black or brown patch
Often on palate or gums
7. Sarcoma
Develops from muscle, bone, or connective tissue
Includes osteosarcoma, fibrosarcoma
Rare in the oral cavity
Causes and Risk Factors of Mouth Cancer
Several factors increase the risk of developing mouth cancer, including:
Tobacco use (smoking cigarettes, bidis, chewing tobacco, gutkha, pan masala)
Excessive alcohol consumption
Betel nut (areca nut) chewing
Poor oral hygiene
Human Papillomavirus (HPV) infection
Prolonged sun exposure (risk for lip cancer)
Family history of cancer
Avoiding tobacco and alcohol can significantly reduce the risk of mouth cancer.
Common Symptoms of Mouth Cancer
Early symptoms of mouth cancer are often ignored, which leads to late diagnosis. Common signs include:
A non-healing mouth ulcer
Red or white patches inside the mouth
Persistent mouth pain or soreness
Difficulty in chewing, swallowing, or speaking
Lump or thickening in the cheek
Loose teeth without dental cause
Numbness in the mouth or tongue
Unexplained bleeding in the mouth
If these symptoms last for more than two weeks, it is important to consult a doctor immediately.
Diagnosis of Mouth Cancer
Mouth cancer is diagnosed through a combination of:
Physical examination of the mouth
Biopsy of suspicious lesions
Imaging tests such as CT scan, MRI, or PET scan
