Lip Cancer Can Strike Without Tobacco: Experts Reveal Lesser-Known Risk Factors

When people think about lip cancer, tobacco use is often the first risk factor that comes to mind. Smoking and smokeless tobacco can increase the likelihood of developing the disease, but they are not the only factors associated with lip cancer. Prolonged exposure to sunlight, certain infections, occupational exposure and other factors may also contribute to the risk. Understanding these lesser-known factors can help people recognise potential risks and seek medical attention when changes on the lips persist.

One important risk factor is long-term exposure to ultraviolet (UV) radiation from sunlight. The lips have relatively thin skin and receive direct exposure to the sun, making prolonged and repeated UV exposure relevant to lip health. People who spend many hours outdoors, particularly without adequate protection, may have greater exposure over time. Using lip products with sun protection and reducing unnecessary exposure during periods of intense sunlight can be useful preventive measures.

Human papillomavirus (HPV) is another factor that doctors consider when assessing certain cancers of the mouth and head-and-neck region. HPV is a common virus, and some types can contribute to the development of cancers in specific parts of the body. While HPV is better known for its association with other cancers, its potential role in cancers affecting the oral and head-and-neck region means persistent or unusual lesions should not be ignored. Occupational and environmental exposure may also matter, particularly for people whose work involves prolonged outdoor activity.

Farmers, construction workers, fishermen and others who spend substantial amounts of time in direct sunlight can have significant cumulative UV exposure. The risk is influenced by the duration and intensity of exposure, along with other individual factors. Protecting the lips from excessive sunlight can therefore be an important part of preventive care. Another reason not to assume that every lip lesion is tobacco-related is that lip cancer can occur in people who do not smoke or use tobacco. Age, immune status, genetic susceptibility and other individual factors may influence cancer risk.

Having no history of tobacco use does not mean that a persistent change on the lip should automatically be considered harmless. People should pay attention to changes such as a sore or ulcer that does not heal, a persistent lump, unusual thickening, a change in colour, bleeding, crusting or persistent pain. Such symptoms do not necessarily indicate cancer and can have several other causes, but persistent or unexplained changes warrant assessment by a doctor or dentist. Early evaluation is particularly important because cancers detected at an earlier stage can generally offer more treatment options. Prevention involves addressing risk factors that can be modified.

Avoiding tobacco, protecting the lips from excessive sunlight and maintaining good oral health can help reduce avoidable risks. People who regularly spend time outdoors should consider appropriate sun protection, while those with persistent lip changes should avoid self-diagnosing the condition. The key message is that lip cancer is not exclusively a tobacco-related disease. While tobacco remains an important preventable risk factor, prolonged UV exposure, HPV and other individual or environmental factors can also play a role. Being aware of these risks and getting persistent or unusual changes checked by a qualified healthcare professional can help ensure that potentially serious conditions are not overlooked.
