Cancer: Why Early Detection Saves Lives

Sudden changes in the skin—such as new moles, dark spots, or scaly patches—can be worrying. While many are harmless, some may indicate skin cancer, one of the most common yet treatable cancers worldwide. Over 1.5 million new cases are diagnosed annually, and catching it early is crucial, especially for melanoma, the deadliest form.

The three main types of skin cancer are Basal Cell Carcinoma (BCC), Squamous Cell Carcinoma (SCC), and Melanoma. BCC often appears as a shiny bump or scaly patch and rarely spreads, while SCC may form as a crusty red nodule that grows quickly.

Melanoma is the most dangerous type because it can spread rapidly to other organs. It often appears as a mole with irregular edges, uneven colors, or changes in size and shape. Detecting it early dramatically increases survival rates.

To help identify melanoma, dermatologists use the ABCDE rule—Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, and Evolving appearance. Any mole or spot that fits these descriptions should be checked by a professional right away.

Nodular melanoma, a fast-growing subtype, can develop suddenly and may not follow the usual ABCDE pattern. Because it progresses quickly, prompt evaluation is essential.

Performing monthly self-exams can make a life-saving difference. Use mirrors to inspect hard-to-see areas and note any moles that change, bleed, or fail to heal. Documenting your findings helps track subtle changes over time.

Prevention is also key. Apply broad-spectrum sunscreen with SPF 30 or higher daily, avoid tanning beds, and wear hats and protective clothing when outdoors. Even on cloudy days, UV exposure can cause damage.

Early detection truly saves lives. Recognizing changes, protecting your skin, and consulting a dermatologist at the first sign of concern are the most effective ways to prevent serious outcomes.
