What Kind of Cancer Does Smoking Cause?

Quitting smoking isn’t easy, but here’s another reason you should make the effort. Smoking is more than just a cause of bad breath; it significantly raises your risk of developing oral cancer, which includes cancer of the mouth, throat, salivary glands, tongue or lip.

What are the Symptoms of Oral Cancer?

In the early stages, oral and throat cancers can have symptoms similar to a toothache or they are painless. Many cases of oral cancer are seriously advanced by the time they are detected. That’s why it is important to examine your mouth periodically. If oral cancer is identified early, it is almost always treatable.

Bad breath is an early sign of oral cancer, whether or not you are a smoker. Other early signs of oral cancer include lumps or white, red or dark patches inside the mouth, difficulty chewing, swallowing or moving the jaw, feeling that something is stuck in the throat, numbness in the mouth, thickening of the cheeks, or voice changes.

How to Prevent Oral Cancer

Tobacco use is the top risk factor for oral cancer, so the best way to reduce risk is to quit smoking or using other tobacco products. But other keys to oral cancer prevention and the promotion of oral health include seeing a dentist regularly and following a complete oral care routine that includes twice-daily tooth brushing and daily flossing.

How exactly does smoking damage oral health?

Smoking can harm oral health by irritating mouth tissues, reducing blood flow to the gums, slowing healing, and making it harder for the body to fight infection. These effects can increase the risk of gum disease, oral infections, stained teeth, bad breath, and oral cancer.

Can quitting smoking reverse the effects of gum disease?

Quitting smoking significantly improves oral health by enhancing healing, reducing inflammation, and increasing the effectiveness of gum disease treatments. While it can halt further damage and possibly help the gums recover to some extent, it generally cannot completely reverse damage already done by advanced gum disease.

What are the early signs of oral cancer caused by smoking?

Early signs of oral cancer linked to smoking include persistent sores, lumps, or patches in the mouth that do not heal, as well as the appearance of red or white lesions on the gums, tongue, or lining of the mouth. Other signs can include unexplained pain or numbness, difficulty chewing or swallowing, changes in speech, and persistent bad breath. If any of these symptoms persist, it's important to get evaluated by a healthcare professional.

Does vaping affect breath and oral health the same way cigarettes do?

No. Vaping does not affect your mouth in exactly the same way as cigarettes, but it can still harm oral health. It may contribute to dry mouth, bad breath, and gum irritation, so it is not risk-free for your mouth.

Why do smokers have dry mouths?

Smoking can contribute to dry mouth by irritating the tissues in the mouth and affecting saliva flow. Nicotine and other chemicals in tobacco smoke may also reduce blood flow, which can make the mouth feel drier and contribute to bad breath and a higher risk of oral health problems.
