Does Smoking Cause Mouth Cancer?
October 31, 2023 | by Yashaswi Pathakamuri | Posted in FAQ's
Yes, smoking is a well-established risk factor for oral cancer, including mouth cancer. Smoking tobacco, whether in the form of cigarettes, cigars, or pipes, exposes the mouth and surrounding tissues to harmful carcinogens (cancer-causing substances) and toxins. Over time, the continuous exposure to these harmful chemicals can lead to the development of oral cancer.
Oral cancer encompasses cancers of the mouth, lips, tongue, throat, and the lining of the oral cavity. These cancers can be life-threatening if not diagnosed and treated early. The risk of developing oral cancer is significantly higher in individuals who smoke compared to those who do not.
The harmful effects of smoking on the oral cavity and the development of oral cancer are due to several factors, including:
- Chemical exposure: Tobacco smoke contains numerous chemicals, many of which are carcinogenic. When these chemicals come into contact with the tissues in the mouth and throat, they can lead to DNA damage and the formation of cancerous cells.
- Irritation and inflammation: Smoking can cause chronic irritation and inflammation of the oral mucosa, increasing the likelihood of cellular changes that can progress to cancer.
- Reduced immune response: Smoking weakens the immune system’s ability to fight off cancerous cells and infections, making it more challenging for the body to prevent the development of cancer.
- Synergy with alcohol: Smoking and heavy alcohol consumption are often associated with an increased risk of oral cancer. When combined, the risk is even higher.
It’s important to note that the risk of developing oral cancer is significantly higher in long-term smokers, and the more cigarettes smoked per day, the greater the risk. However, quitting smoking at any point in time can reduce the risk of developing oral cancer and other serious health conditions. The risk gradually decreases as the body starts to repair itself after quitting.
Regular dental check-ups and self-examinations can help with early detection of oral cancer. If you smoke or have a history of tobacco use, it is crucial to be aware of the risks and seek medical attention if you notice any unusual changes in your oral health, such as persistent sores, lumps, white or red patches, or difficulty swallowing. Additionally, quitting smoking is one of the most effective ways to reduce the risk of oral cancer and improve overall health.
