Can Chewing Tobacco Cause Oral Cancer?

In the world of oral health, the menace of oral cancer looms large, with one particular habit standing out as a major contributor — chewing tobacco.  Chewing tobacco, a practice ingrained in various cultures, poses a significant threat to oral health. The primary link between oral cancer and chewing tobacco lies in the potent mix of harmful chemicals found in these products. Smokeless tobacco, often chewed or snuffed, exposes the delicate tissues of the oral cavity to carcinogens, leading to the development of cancerous cells over time.

Causes Of Oral Cancer Due To Chewing Tobacco

Chemical Exposure:

Chewing tobacco introduces a cocktail of harmful chemicals into the oral cavity, with     the most notorious being tobacco-specific nitrosamines (TSNAs). These chemicals are   potent carcinogens, initiating and promoting the development of cancerous cells in the oral tissues.

Carcinogenic Impact:

TSNAs, found in abundance in smokeless tobacco, act as powerful carcinogens by causing damage to the DNA within cells. This damage sets the stage for the uncontrolled growth of abnormal cells, leading to the formation of cancerous tumors.

Chronic Irritation:

The abrasive nature of chewing tobacco can result in chronic irritation to the delicate tissues of the mouth. This persistent irritation creates an environment conducive to the development of oral cancer over time.

Signs Of Oral Cancer Due To Tobacco

Persistent Sores:

Chewing tobacco users may experience persistent sores or ulcers in the mouth that do not heal. These sores can be indicative of abnormal cell growth.

Unexplained lumps:

Development of lumps or masses in the oral cavity is a concerning sign. These lumps may be palpable in the gums, tongue, or other areas of the mouth.

White Or Red Patches:

The formation of abnormal white or red patches on the gums, tongue, or inner cheeks is a potential indicator of cellular changes associated with oral cancer.

Difficulty Swallowing:

Individuals with oral cancer may experience difficulty or pain while swallowing, reflecting the impact of the disease on normal oral functions.

Unexplained Pain:

Oral pain without an apparent cause, especially when persistent, could be a symptom of advanced oral cancer.

Treatments for Oral Cancer Due to Tobacco


Surgical procedures are employed to remove tumors or affected tissues. The extent of surgery depends on the stage and location of the cancer.

Radiation Therapy:

High-energy radiation is used to target and destroy cancer cells. This treatment is particularly effective for localized oral cancers.


Drugs are administered to kill or slow down the growth of cancer cells. Chemotherapy may be used alone or in conjunction with other treatments.

Combination Therapy:

Depending on the specific case, a combination of surgery, radiation, and chemotherapy may be recommended for a comprehensive and more effective approach.

Prevention: Shield Against Oral Cancer Due To Tobacco

Smoking Cessation:

Seeking professional support and engaging in smoking cessation programs are crucial steps in overcoming tobacco addiction.

Adopt Healthier Alternatives:

Individuals can reduce their risk of oral cancer by substituting tobacco-chewing habits with healthier alternatives, such as sugar-free gum or sunflower seeds.

Oral Hygiene Practices:

Maintaining good oral hygiene is essential in preventing oral cancer. Regular brushing, flossing, and dental check-ups reduce the risk of chronic irritation and infection.

Regular Dental Check-Ups:

Routine dental check-ups play a pivotal role in early detection. Dentists can identify potential issues in their early stages, allowing for prompt intervention.

Chewing tobacco and snuff can cause mouth and throat cancer. There are some athletes who have developed mouth cancer after only 6 or 7 years of using spit tobacco. It's hard to cure because it spreads fast. If not caught right away, major surgery is often needed to take out parts of your mouth, jaw, and tongue.

One broad class of tobacco-specific carcinogens is nitrosamines. These chemicals are derived from nicotine. They form in the tobacco plant during curing. Like polycyclic aromatic hydrocarbons, they can bind to DNA and promote inaccurate DNA copying.

Chewing tobacco can reduce the flow of saliva in your mouth. When this happens there tends to be an increase in plaque and tartar. This all results in increased risk of gum disease and tooth decay.
