Basal cell carcinoma is a type of skin cancer that typically arises on sun-exposed areas of the skin, including the eyelids. The eyelids are particularly vulnerable to this type of cancer due to their thin skin and high sun exposure.
Basal cell carcinoma of the eyelid can occur anywhere on the eyelid, including the canthus. The canthus is the corner where the upper and lower eyelids meet. This type of cancer is more common in older adults with fair skin, but it can occur in anyone.
Basal cell carcinoma of the eyelid often presents as a painless bump or lesion on the eyelid. It may be flesh-colored or darker in color. Over time, the lesion may grow and become more noticeable. If left untreated, it can spread to other parts of the body and cause serious health problems.
If you notice any unusual bumps or lesions on your eyelids, including the canthus, it is important to see a doctor right away. Early detection and treatment can help prevent serious health problems.
