Lip cancer is a type of cancer that develops on the lips. It can affect either the upper or lower lip, though it is more frequently observed on the lower lip. Recognizing its signs is important for early identification, as prompt awareness can lead to timely diagnosis and treatment.
Key Visual Indicators
Lip cancer often appears as a sore or lesion on the lip. These growths can be flat or slightly raised, and are often discolored. Their color may vary, appearing reddish, white, or flesh-toned, and they can develop a scaly or crusty texture. In some instances, the affected area might look like a lump or a wart-like growth.
The most common site for lip cancer is the lower lip. However, these lesions can appear anywhere on the lips, including the corners or the inner surface. Initially, a cancerous lesion might resemble a common cold sore or canker sore. Unlike benign sores, a key characteristic of lip cancer is its persistent nature and failure to heal.
Additional Accompanying Symptoms
Beyond its visual appearance, lip cancer can present with other physical sensations. Individuals may experience discomfort in the affected area, including pain, tenderness, or tingling. Numbness in the lip or surrounding skin can also occur.
A persistent sore that bleeds easily without obvious injury is a concerning sign. This bleeding may occur spontaneously or with minor irritation. Some individuals might notice a feeling of tightness in their lip or difficulty with movement, which can impact actions like speaking or eating. Swelling in the lips that does not resolve is another accompanying symptom.
Changes Over Time
A key differentiator between a harmless lip irritation and a cancerous lesion is its behavior over time. Unlike typical sores or wounds, which heal within a few days to two weeks, lip cancer lesions do not resolve on their own. They persist for extended periods, often longer than two weeks, even with home care.
As the condition progresses, the lesion may grow larger or change shape. The texture or color of the area might also evolve, becoming more pronounced or developing new characteristics like increased crusting or thickening. This lack of healing and the tendency for the lesion to change or worsen are important indicators that distinguish cancerous growths from benign, temporary conditions.
When to Consult a Professional
It is important to seek prompt medical attention if any unusual changes on the lips are observed. Any sore, lump, or discolored patch on the lip that does not heal within a two-week period should be evaluated by a healthcare professional. This includes persistent bleeding or any new sensations like numbness or pain.
Self-diagnosis of lip cancer is unreliable due to its resemblance to other common, less serious conditions. A doctor or dentist can conduct a proper examination and perform diagnostic tests, such as a biopsy, to accurately determine the cause of the lip abnormality. Early detection of lip cancer significantly improves treatment outcomes and survival rates.
