The 10 most common symptoms of skin cancer are precursors! handheld dermatoscope Keep in mind 5 key points of life and diet to prevent skin cancer.

According to the Top 10 cancer statistics and rankings released by the Ministry of Health and Welfare last year, electronic dermatoscope skin cancer ranked eighth and ninth among men and ninth among women. Ultraviolet light, the biggest cause of skin cancer, also reached a new high last year, and the number of people suffering from other skin diseases is also on the rise. If protection measures are not strengthened, this is a problem that cannot be ignored, and how to prevent skin cancer has become a major issue that must be recognized.

Common symptoms, precursors, and types of skin cancer

Skin cancer is a malignant tumor on the surface of the skin that most often occurs on the face, neck and arms, 365nm UV Lamp the three areas most exposed to the sun. According to the Cancer Prevention Technology Research and Development Center of Taipei United Hospital, there are three main types of skin cancer:

Types of skin cancer

Basal cell carcinoma: The most common skin malignancy, but it is less likely to metastasize, with 70 to 90 percent occurring on the face and areas exposed to the sun, and can lead to local nerve damage if not detected in time.

Squamous cell carcinoma (SCC) : the second most common skin malignancy in Asia, occurs mostly in sun-exposed areas of the skin, but can also occur in areas where chronic damage or radiation occurs, such as the legs or abdominal wall, and may spread through the lymph glands to other internal organs, swelling the lymph nodes.

It is the third most common skin cancer and the most common melanoma in Asia. Not only is it deadly, it's easily transferable. It usually occurs in the extremities, such as the fingers, toes, palms, and soles of the feet, but can also occur in other parts of the body, including the face and mucous membranes.

Skin cancer type and appearance symptom comparison table

Appearance and symptoms

Basal cell carcinoma

Bright protrusions around the epidermis

Skin color with small bumps

There are occasional festering wounds in the middle

Squamous cell carcinoma

Small red scab scaly patches

Most of them are raised keratoma or ulcers

It usually develops into a mushroom-like lump.

Melanocytic carcinoma

Could be dark patches/protrusions

(Distinguish from benign pigmented nevus and mother spot)

What are the high-risk groups for skin cancer?

Skin cancer is mainly caused by exposure to the sun. Prolonged exposure to ultraviolet light can cause pathological changes in skin cells. Other causes include burns, radiation, genetics, chronic arsenic poisoning, or a weakened immune system. Therefore, the following people should pay more attention:

Farmers, fishermen and workers who have long worked in the sun

Workers who, because of their work, have to be exposed to radioactive substances, asphalt, kerosene or tar for long periods of time.

Patients with a chronic skin condition

Family history of skin cancer

Some people have been drinking groundwater containing arsenic (in areas where crow's foot is prevalent)

People with a large number of hemorrhoids or specially shaped hemorrhoids.

How skin cancer is diagnosed

Skin cancer is divided into "hemato-oncology" and "dermatology."

Skin cancer is detected by a "skin biopsy," a minor procedure that requires local anesthesia. The operation can be completed in about half an hour. The doctor will first take a piece of skin tissue under local anesthesia and use a microscope for diagnosis. At present, advanced countries are still trying to study the diagnosis of skin cancer without surgery, but at this stage, the diagnosis is still through skin biopsy.

Skin cancer treatment, prevention methods

How is skin cancer treated?

Skin cancer is relatively easy to detect early in the development of cancer, and the treatment method will be different because of the speed of discovery. If we can detect early in China, most students only need to undergo resection to achieve radical treatment. Therefore, if enterprises have doubts about skin cancer, please seek medical treatment as soon as possible to avoid delayed treatment. Here's how skin cancer treatments work:

Basal cell carcinoma or squamous cell carcinoma, if caught early, usually only requires surgical removal with a response rate close to 100%, but if caught late, radiation or chemotherapy may need to be added.

However, in the case of malignant melanoma, not only surgical removal is required, but in advanced stages, amputation, lymph node removal, chemotherapy, radiation, or immunotherapy may be required. In addition, if malignant melanoma has metastasized to internal organs, the mortality rate remains high even if treated.
