Cancer of the lip refers to a type of malignant tumor that develops in the cells of the lip, which can include the upper or lower lip. It is categorized as a specific type of oral cancer that specifically affects the lip region.
Cancer is an abnormal and uncontrolled growth of cells that can infiltrate and destroy surrounding tissues. In the case of lip cancer, uncontrolled cell growth occurs in the lip cells, leading to the formation of a tumor. This tumor can be either primary, originating directly in the lip cells, or secondary, spreading from other parts of the body.
Risk factors for developing cancer of the lip can include excessive exposure to ultraviolet (UV) radiation from the sun or tanning beds, particularly for individuals with fair skin. Other factors, such as smoking or tobacco use, heavy alcohol consumption, a weakened immune system, and certain genetic conditions, can also increase the likelihood of developing lip cancer.
Common symptoms of lip cancer may include the development of a sore or lump that fails to heal, persistent pain, swelling, or thickening of a region of the lip, changes in the color or texture of the lip, or difficulty in moving the lip. Diagnosing lip cancer typically involves physical examination, biopsy, and imaging tests like CT scans or MRIs.
Treatment for lip cancer can vary depending on the stage and spread of the cancer, and may include surgery, radiation therapy, chemotherapy, or a combination of these approaches.
