Malignant Melanoma
Malignant melanoma is a type of skin cancer that develops when melanocytes, cells responsible for producing melanin (skin color), grow out of control. These tumors can appear anywhere on the body, but they are most commonly found in areas exposed to ultraviolet (UV) radiation, such as the face, neck, and arms.
Melanoma is a complex disease with various subtypes with different characteristics. However, certain characteristics are common to malignant melanomas, including:
Superficial appearance: Malignant melanomas often appear as dark, uneven patches on the skin.
Diameter: They can range in size from a few millimeters to several centimeters.
Border: They often have irregular borders with jagged edges.
Color: The color may vary from black to brown to red, sometimes with a blue or purple tint.
Shape: They can be irregular, with multiple lobes or irregular borders.
Risk Factors for Melanoma
Several factors increase the risk of developing melanoma, including:
Exposure to ultraviolet (UV) radiation: UV radiation from the sun, tanning beds, and certain indoor sources can trigger melanoma development.
Fair skin: Melanoma is more common in people with fair skin as it lacks melanin to protect against UV damage.
Family history: There is an increased risk of melanoma in individuals with a family history.
Sunburns: Excessive exposure to UV radiation can increase the risk of melanoma.
Weakened immune system: Certain medical conditions, medications, and diseases can weaken the immune system, increasing susceptibility to melanoma
