Moles: The initial indicators of skin cancer?

Indeed, some moles can evolve into melanoma, a form of skin cancer. It's crucial to distinguish melanomas from other types of skin cancers such as basal cell carcinomas and squamous cell carcinomas. Melanoma is the most aggressive and develops from melanocytes. It's often linked to high exposure to UV rays and can spread rapidly and prove fatal if not detected at an early stage. Basal cell carcinoma is the most common skin cancer, forming from the basal cells of the epidermis, and, although usually localized, it can cause deformities or loss of organ function. Lastly, squamous cell carcinoma also develops from keratinocytes and can spread if not properly managed.

Although a mole can evolve into melanoma, it does not necessarily indicate a precursor to skin cancer. However, certain changes should raise concern and require a dermatological consultation.

One of the initial concerning signs is a change in shape or color. If a mole becomes irregular or its color changes, it could indicate the formation of a melanoma. Similarly, a nevus that grows quickly or exceeds 6 mm in diameter should be closely monitored. The texture of the mole is also an indicator. If the surface becomes rough, or if a crust or oozing appears, it could mean that the skin cells are changing. Experiencing pain or itching sensations is another warning signal. Generally, benign moles are stable, so any change is a factor to consider in the fight against melanomas.

One of the simplest and most effective ways to determine if a mole is evolving into melanoma is to refer to the ABCDE method which helps identify signs of malignancy. This system is based on the observation of five criteria: asymmetry, irregular borders, heterogeneous color, diameter greater than 6 mm, and the evolution of the mole over time. A mole that presents any of these signs must be examined by a dermatologist. In case of suspected melanoma, a dermatoscopy is performed to analyze the structure of the nevus. If necessary, a biopsy is carried out to confirm or refute a melanoma diagnosis.
