What is skin cancer?

Skin cancer is cancer that forms when skin cells change into cancerous cells. One of the main causes of cytopathy is long-term exposure to ultraviolet radiation, 365nm UV Lamp such as our arms, the back of the hands, face, scalp, ears, lips, or when we often wear shorts in the summer and expose their legs, are more susceptible to UV exposure in the sun exposure areas of the skin.

People in Hong Kong and Taiwan do not know much about skin cancer. Because yellow skin produces higher levels of melanin, which reduces UV absorption, the risk of skin cancer is lower than that of white people. According to the statistics of the National Health Department of the Ministry of Health and Welfare of Taiwan, there were 4,049 skin cancer patients in the year 107 (2018), about 9.6 people out of every 100,000 people. However, even if it seems that the proportion is not high, but under the change of demographic structure, the trend of patients has increased year by year. ▼ The sun's ultraviolet rays are the culprit of cancer, which is the best point to do sunscreen?

As Taiwanese, although our risk of skin cancer is low, we cannot take it lightly! Studies have shown that people of color are often diagnosed at advanced stages of skin cancer and have a worse prognosis for skin cancer than Caucasians, so there is still a need for better skin protection and self-examination to reduce the risk of skin cancer. Skin cancer symptoms

The symptoms of skin cancer vary by type and can usually be divided into three types: basal cell carcinoma, squamous cell carcinoma, and melanoma, but most skin cancers are usually asymptomatic and painless. Fortunately, the skin is the part we can see and touch. By looking at the texture and color of the skin, it helps to identify signs of skin cancer as early as possible. The following are the symptoms and characteristics of various skin cancers: basal cell carcinoma.

Basal cell carcinoma tends to occur in areas of the skin that are frequently exposed to the sun, such as the neck or face in China, and it is the most common type of skin cancer in China. As mentioned earlier, the increase in the number of skin cancer cases may also be related to Taiwan's aging population. Symptoms of basal cell carcinoma may include:

1. Lesions look shiny and smooth.

2. Pearly in color, but may also be flesh-colored, brown or blue-black, or appear red.

3. You may have ulcers.

Squamous cell carcinoma

Squamous cell carcinoma, similar to basal cell carcinoma, is also caused by prolonged sun exposure. This is the second most common skin cancer in the elderly, and possible symptoms are:

1. The lesions have keratosis, hard nodules and erythema. The surface is rough, crusted and desquamated, and the patients are prone to itching.

2. The color is usually red, and it is easy to bleed due to ulcers.

3. The lesion is most likely to develop into a large mushroom shaped mass.

melanoma

Melanoma is the least common type of skin cancer, but it is also the most serious. It can appear on the skin anywhere on the body, making existing moles cancerous and prone to metastasis. The following are common features of melanomas:

1. The lesions were tubercles or plaques.

2. The color is black, but because the pigment is not evenly distributed, it may be black and skin color.

3. Irregular lesion edges.

Bowen's disease caused by arsenic poisoning

In addition to the three common types of skin cancer we have listed above, there is also a part of Taiwan's elderly with Bowen's disease (Bowen's disease), which is actually the same as Blackfoot disease (Blackfoot disease), most of which originates from the early residents of southwest China and the coastal areas of Taiwan. Because drinking well water and groundwater containing high amounts of arsenic, over time, there are lesions on the skin due to chronic arsenic poisoning events, which may further evolve into squamous cell carcinoma. What factors are more likely to cause skin cancer? (Click the picture to see 👇👇👇) +6

1. Fair skin people: Fair skin means less melanin, which helps protect against UV rays, which is why white people are especially prone to skin cancer.

2. Overexposure to the sun: People who enjoy outdoor sports or have to work in the sun for a long time can be a higher threat to their skin than others, especially if they don't do a good job of sun protection, they will not only get sunburned, but also have an increased risk of skin cancer.

3. Many moles: People with many different moles have a higher probability of abnormal moles than the average person. These abnormal moles are irregular in shape and larger than normal moles, which is likely to become cancerous.

Four. Actinic keratosis, also known as actinic keratosis, is an actinic keratosis of the skin that results from prolonged exposure to sunlight. Patients may have brown or red crusted plaques that may develop into squamous cell carcinoma.

5. A family history of skin cancer.

6. Prolonged exposure to radiation.

7. People with weakened immune systems such as AIDS.

8. Arsenic poisoning.

9. Genetic defects in DNA repair mechanisms, such as xeroderma pigmentosa and Muir-Torre syndrome, also put affected individuals at high risk for skin cancer.
