Three common skin problems often occur in individuals over the age of 50. The first issue, which affects both the body and the mind, is "wrinkles and sagging skin on the face." The second issue is "dry skin," which older individuals often experience. The third problem, which is frequently encountered and can be life-threatening, is "skin cancer."
For Thai people, three main types of skin cancer are commonly encountered, depending on their lifestyle choices in their younger years. The most common type is "Basal Cell Carcinoma," which appears as a lesion or raised bump, often with a color similar to the surrounding skin, making it difficult to detect.
People may mistakenly think it is simply a sign of aging and ignore it until it eventually becomes an open wound. Another type is "Squamous Cell Carcinoma," which may be caused by sun exposure or consuming certain herbal medicines. It typically presents as an ulcer or an abnormal growth that appears more rapidly than usual. Both of these types can be diagnosed by a dermatologist, who may confirm the diagnosis through a biopsy.
The third type is called "Malignant Melanoma," which is less common, primarily affecting people in Western countries, but can still occur in Thai people. The doctor has personally diagnosed three cases. Diagnosis requires a high-powered magnifying lens to observe the tumor and assess the risk of it being "Malignant Melanoma." If there is a risk, treatment involves surgical removal, which differs from the first two types, as it requires wide excision to ensure complete removal in one session. Additional medication may be prescribed after surgery for the best treatment outcome.
The primary cause of skin cancer is sun exposure. Unprotected sun exposure from childhood is a significant factor in the development of skin cancer. To recognize the first two types of skin cancer, "Basal Cell Carcinoma" and "Squamous Cell Carcinoma," you should look for abnormal lumps or bumps on the skin that were not previously present.
Skin cancer can be easily identified by noticing abnormal lumps or growths on the skin, particularly if they become open sores or start bleeding. If you observe any of these signs, you should immediately see a doctor. For "Malignant Melanoma," the most dangerous form of skin cancer, look for moles that change color or have unclear borders. If you notice any of these changes, do not wait to observe further; visit a doctor immediately.
"Sunlight" is a significant factor in causing wrinkles on the face and skin cancer due to the presence of ultraviolet B (UVB) rays, which are a type of light wave that can cause skin cancer. You can still enjoy being outside without fear of harm, but if you plan to stay outdoors for more than two hours, take precautions. For example, wear a hat, use an umbrella, and apply sunscreen generously. Don't worry about your face becoming too pale, as this ensures protection from the sun.
