Skin Cancer Warning: Spot the Signs on Your Legs with ‘ABCDE’

Dr. Jordan Richardson has emphasized the importance of skin cancer awareness, particularly in Arizona, where the high UV index significantly increases risk. Residents enjoy abundant sunshine and outdoor activities but must be vigilant about skin health.

Commonly, cancerous or pre-cancerous lesions form on visible areas like the face and arms. However, the legs and feet warrant careful examination too, including toenails. This broader awareness could be lifesaving.

The late musician Bob Marley serves as a notable example. He ignored a dark spot on his toenail, mistaking it for an injury, and ultimately succumbed to acral lentiginous melanoma. His story illustrates the necessity of timely intervention and proper skin lesion evaluation.

Self-screening for skin cancer is vital. Using the ABCDE rule can help identify potentially malignant moles:

• A – Asymmetry: One half of the mole differs from the other.
• B – Border: Edges are irregular or poorly defined.
• C – Color: Mixed shades including brown, black, red, white, or blue.
• D – Diameter: Larger than 6 millimeters, although smaller melanomas exist.
• E – Evolving: Changes in size, shape, or color over time.

For non-melanoma skin cancers, watch for persistent red patches, scaly lesions, or sores that won’t heal. Timely medical consultation can address these warning signs effectively.

At Maricopa Foot and Ankle, physicians can screen for skin cancer on lower extremities. If a suspicious lesion appears, a biopsy will confirm malignancy through microscopic examination by a pathologist. Additional testing, such as immunohistochemistry (IHC) or genetic analysis, can provide further insights for treatment options.

Due to Arizona’s intense sun exposure, preventative measures are crucial. Residents should apply broad-spectrum SPF 30+ sunscreen daily, wear protective clothing and sunglasses, seek shade during peak hours, and conduct regular skin checks.

Early detection dramatically improves the treatability of skin cancer. Any concerns regarding skin lesions warrant a medical evaluation. Protective actions today can foster a healthier tomorrow for one’s skin amidst Arizona’s sun.
