Skin cancer is one of the most common types of cancer worldwide, and long-term sun exposure increases the risk. In Thailand, where UV levels are high throughout the year, regular screenings can help detect early signs of skin abnormalities before they become serious, or in some cases, deadly. Understanding skin cancer causes and the screening process allows you to take proactive steps toward maintaining healthy skin.
Common Causes of Skin Cancer
Several factors contribute to skin cancer, including:
- Prolonged Sun Exposure: UV radiation from the sun damages skin cells over time, increasing the risk of cancer.
- Tanning and Artificial UV Light: Regular use of tanning beds exposes the skin to concentrated UV rays.
- Genetics: A family history of skin cancer can increase the likelihood of developing the condition.
- Fair Skin and Frequent Sunburns: People with lighter skin tones are more prone to sun damage.
- Exposure to Harmful Chemicals: Some industrial chemicals and pollutants have been linked to skin cancer.
How to Prepare for a Skin Cancer Screening
A skin cancer screening is a non-invasive exam conducted by a dermatologist or trained healthcare professional. Before your appointment make sure you:
- Avoid applying makeup or lotions to ensure clear visibility of your skin.
- Take note of any changes in moles or skin spots, including size, shape, or color variations.
- Wear comfortable clothing that allows easy access to areas commonly exposed to the sun.
The Skin Cancer Screening Process
During a screening, a dermatologist will:
- Examine Your Skin: The doctor will check for irregular moles, discoloration, or unusual spots on the face, neck, arms, legs, and torso.
- Use a Dermatoscope: This handheld device magnifies the skin to detect early signs of cancer.
- Assess Any Suspicious Areas: If an abnormal growth is found, further evaluation may be needed.
What Happens If an Abnormal Spot Is Found?
If a dermatologist identifies a suspicious lesion, additional tests may be recommended, including:
- Biopsy: A small sample of skin is taken and examined under a microscope to confirm whether it is cancerous.
- Imaging Tests: If the doctor suspects the cancer has spread, imaging scans may be used for further assessment.
- Follow-Up Appointments: Some lesions may require regular monitoring to track changes over time.
Thailand offers high-quality dermatology services in hospitals and specialized clinics. Many facilities in Bangkok, Phuket, and Chiang Mai provide screenings using advanced diagnostic tools. Regular skin checks, especially if you have a history of sun exposure or fair skin, can help in early detection.
Taking Control of Skin Health
Routine skin cancer screenings are an important part of preventive healthcare. Understanding skin cancer causes and staying proactive about regular check-ups can reduce risks and improve early detection rates. If you notice any changes in your skin, speak to a dermatologist who can provide peace of mind and help maintain long-term skin health.
