Prevention, Screening, and Treatment Interpretation

Risk Factors and Causes Interpretation
The Australian sun is a statistically prolific artist, painting a landscape where nine out of ten non-melanoma skin cancers are its signature work, yet its masterpiece is a melanoma risk that skyrockets one hundred fold for fair skin, a danger amplified by every childhood sunburn, a depleted ozone layer, and even your own red hair or freckles, reminding us that in a nation where three quarters of the population is genetically predisposed, seeking shade and slapping on sunscreen is less a suggestion and more a civic duty for survival.
