Skin cancer is the most common form of cancer globally, affecting millions each year. Despite its prevalence, it is also one of the most treatable cancers, especially when detected early. The prognosis for patients diagnosed in the early stages is overwhelmingly positive, with cure rates exceeding 90% for many types. In Singapore, where access to healthcare is excellent and dermatological expertise is readily available, early detection and treatment are not only possible but highly effective.

This essay explores the curability of skin cancer when caught early, the importance of regular screenings, and the role of a Singapore dermatologist clinic in managing this condition.

Understanding skin cancer

Skin cancer develops when abnormal skin cells grow uncontrollably, often as a result of DNA damage caused by exposure to ultraviolet (UV) rays. The three most common types are:

• Basal cell carcinoma (BCC) – the most common and least aggressive.
• Squamous cell carcinoma (SCC) – more likely to spread than BCC.
• Melanoma – the most dangerous form, known for its potential to metastasize.

Each type has distinct characteristics and treatment protocols, but they share one crucial trait: early detection dramatically improves outcomes.

The power of early detection

According to the Skin Cancer Foundation, most skin cancers are curable if diagnosed and treated early. For instance, localized melanoma – when confined to the superficial layers of the skin – has a five-year survival rate of over 96%. Similarly, early-stage BCC and SCC can often be removed completely with minor surgical procedures, leaving minimal scarring and no recurrence.

Early detection hinges on vigilance. Regular skin self-examinations and annual visits to a dermatologist are essential. Warning signs include new or changing moles, sores that don’t heal, and unusual skin growths. The ABCDE rule – Asymmetry, Border irregularity, Colour variation, Diameter over 6mm, and Evolving appearance – is a helpful guide for spotting potential melanomas.

Treatment options for early-stage skin cancer

When caught early, skin cancer treatment is typically straightforward and highly effective. Common interventions include:

• Excisional surgery: The cancerous lesion is removed along with a margin of healthy tissue.
• Mohs micrographic surgery: A precise technique often used for high-risk, facial cancers, where layers are removed and examined until no cancer cells remain.
• Cryotherapy: Freezing off precancerous lesions or superficial cancers.
• Topical chemotherapy: Creams like imiquimod for superficial BCCs.
• Photodynamic therapy: A light-activated drug targets and destroys cancer cells.

These treatments are often performed in outpatient settings by a qualified skin cancer surgeon, with minimal downtime and excellent cosmetic results. Always discuss with your dermatologist if non-surgical methods of treatment are available if you have been diagnosed with skin cancer.

Prevention is still the best cure

While early detection is key, prevention remains the first line of defence. Dermatologists recommend:

• Using broad-spectrum sunscreen with SPF 30 or higher to protect your skin from sun damage.
• Wearing protective clothing and hats.
• Avoiding tanning beds and peak sun hours.
• Performing regular self-exams.
• Scheduling annual skin checks with a dermatologist.

These habits are especially important in tropical climates like Singapore, where year-round sun exposure increases the risk of UV-induced skin damage.

Conclusion

So, is skin cancer curable if detected early? The answer is a resounding yes. With vigilant self-monitoring, regular dermatological check-ups, and prompt treatment, the vast majority of skin cancers can be cured before they become life-threatening. In Singapore, patients are fortunate to have access to world-class dermatology clinics and experienced skin cancer doctors who can guide them through every step of diagnosis and treatment.

Whether you’re concerned about a suspicious mole or simply due for a routine check-up, don’t delay.
