【Conclusion】Key Points of This Survey To summarize, the five skin signs to check before summer leisure are: "sudden increase in size," "change in color," "bleeding or discharge," "irregular borders," and "persistent itching or pain." It is recommended to perform a self-check once a month after bathing, by examining your entire body in a mirror. In particular, growths that are "6mm or larger," "asymmetrical," or have "uneven coloration" should not be left untreated; seek medical attention from a dermatologist promptly. - 82.3% responded that they do not perform self-checks for skin growths before summer leisure. - 67.7% have experience leaving "concerning skin growths" untreated. - The top reason for leaving them untreated was "not knowing when to seek medical attention," at 54.2%. Glossary ■ What are Skin Growths (Skin Tumors)? Skin growths (skin tumors) are a general term for benign or malignant lumps that occur on the skin. This includes benign tumors such as moles, atheromas, lipomas, and warts, as well as malignant tumors like basal cell carcinoma, squamous cell carcinoma, and melanoma. ■ What is the ABCDE Rule? The ABCDE rule is a self-check criterion for the early detection of melanoma. It is evaluated based on five items: Asymmetry, Border irregularity, Color variation, Diameter (6mm or larger), and Evolving (changes). ■ What is an Atheroma? An atheroma is a benign tumor where a sac-like structure forms under the skin, accumulating keratin and sebum within it. If left untreated, it can become infected or inflamed, and complete removal requires surgical excision of the entire sac.
