Melanoma, a form of skin cancer that arises from melanocytes, is an important public health concern in Australia. The nation’s high levels of sun exposure contribute significantly to its prevalence.

The Skin Cancer Audit Research Database (SCARD) provides key insights into melanoma characteristics, treatment, and patient outcomes. If you are looking to better understand the different types of skin cancer, explore our guide on Understanding the Different Types of Skin Cancer.

Melanoma Origins: New Lesions vs. Dermal Naevi

One of the most critical aspects of understanding melanoma is its origin. According to the SCARD study, around 70% of melanomas arise as new lesions, meaning they develop independently on the skin without a prior benign mole.

Conversely, about 30% of melanomas are associated with dermal naevi. Importantly, the study highlights that there is no morphing process from a benign mole to melanoma, a common misconception. This distinction is vital for early detection and prevention strategies.

Demographics: Age and Gender Distribution

The SCARD study sheds light on the demographics of melanoma. Notably, 60% of melanoma cases are diagnosed in men.

The average age of diagnosis further emphasizes risk factors, with the mean age being around 65 years for males. These statistics highlight the importance of regular checks, particularly for those in higher-risk categories.

Body Locations: Where Melanomas Occur Most Often

Melanoma occurrence varies by gender, offering insights into lifestyle and exposure patterns. For males, the trunk, particularly the back, is the most common site. This finding aligns with high sun exposure during Australian summers.

For females, the lower extremities, particularly the legs, are the most common areas. Differences in clothing styles and sun exposure patterns likely contribute to this disparity.

The Complexity of Sun Exposure and Melanoma Incidence

Despite high sun exposure on areas like the hands, melanomas are rarely found there. This complexity highlights that while UV radiation is a significant risk factor, other elements are also involved.

Genetic predisposition and having more than 100 moles are among the highest risk factors. For a thorough evaluation, consider expert skin cancer screening in Perth offered by our team.

Treatment and Outcomes

The SCARD study also provides insights into melanoma treatments and outcomes. Treatments range from surgical excision for early-stage lesions to immunotherapy and targeted therapy for advanced cases.

Recent advancements in treatment have improved outcomes significantly. Awareness of early detection, coupled with self-monitoring, plays a key role in enhancing prognosis.

The study emphasizes the importance of staying alert for new or changing moles. Approximately 70% of melanomas arise as new lesions. Be vigilant for any “ugly duckling” or standout lesion that appears on your skin.

Conclusion

The SCARD study underscores the need for awareness and education about melanoma. With most melanomas developing as new lesions and significant gender disparities in prevalence, proactive measures are critical.

Regular skin checks and an understanding of melanoma characteristics can aid early detection and improve outcomes. Fostering a culture of awareness is essential in the fight against this serious disease.
