Skin cancer | dark spots have irregular and uneven edges. Be careful! List three common skin cancer symptoms

Skin cancer is inert and easy to ignore at first, and is often seen as mole treatment, delaying the best time for treatment. handheld dermatoscopeDermatologists say that if the skin has irregular, asymmetrical, uneven dark spots with noticeable color differences in the same dark spot, ulcers, bleeding, and an enlarged or rapidly growing tumor, in order to avoid missing the prime of treatment, you should see a dermatologist as soon as possible to assess whether it is a common skin cancer. These include basal cell carcinoma, squamous cell carcinoma and melanoma.

Chen Yuxi, deputy director of Yafeng Skin Care Clinic in Taiwan Province,electronic dermatoscopewrote on Facebook that the epidermis of the skin is composed of stratum corneum, squamous cell layer and basal cell layer from top to bottom, and common skin cancers are basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and melanoma. What Causes Skin Cancer?

Among them, basal cell carcinoma is the most common, accounting for about 70%, 365nm UV Lampsuch as US President Joe Biden's removal of cancerous skin tissue in his chest at the beginning of this year, which was also confirmed to be basal cell carcinoma. In addition, actor Xiaoji Jeman, who starred in the movie "Mutant Attack: A Werewolf," also had a basal cell carcinoma removed from his face. Chen Yu-sun reminds that the early skin cancer students are painless and itchy, often ignored, resulting in a fatal crisis, three common skin cancers, including a basal cell carcinoma, squamous cell carcinoma and melanoma. 1. Basal cell carcinoma

This basal cell carcinoma is called a cancer, but it is the most benign of all cancers. It usually occurs in areas that are exposed to sunlight, such as the face, neck and hands. Initially, the plaque may resemble a mole or dark spot. Slowly, the plaque may develop lesions such as ulcers, dilation of surrounding microvessels, and bleeding. Fortunately, this type of basal cell carcinoma rarely metastasizes and is very low in malignancy. It usually has a higher healing rate after complete removal and does not require radiation or chemotherapy. A few are because the treatment is too late and the cancer cells penetrate the skin, or are treated as moles, continue to do laser treatment and delay, and become difficult to eradicate and relapse. What does basal cell skin cancer look like?

It accounts for about 20% of skin cancers and is characterized by red, uneven patches with irregularly raised edges, and occasional sores, wounds, or scabs. If not treated early, it can easily spread to other organs. Squamous cell carcinomas are mostly caused by ultraviolet radiation. Cancer can be preceded by actinic keratosis, in which the skin slowly develops a reddish-brown and rough crust that can easily be mistaken for age spots. 3. Melanoma

Although the incidence is low, accounting for only 3 to 5% of skin cancer, but the highest degree of malignancy, may occur in all parts of the body and treatment is difficult, cancer progression speed and high mortality, and will be transferred to the student's body through the blood and lymphatic system, so it is a very complicated and difficult skin cancer. In addition, there are several types of melanoma, Taiwanese and other Oriental species are the most common "acrotype", that is, in the palm, the sole of the foot and the nails or below, so the moles or nails in these parts become black, you need to be vigilant.

Chen Yuxi urged not to ignore skin color changes and lumps, if there is an abnormal situation, should seek medical attention as soon as possible. I've been in three situations. At first, I was treated like a mole and laser removed. However, I found that it was not clean, and the mole festered again and again. It wasn't until I went to his clinic that it was confirmed as a basal cell carcinoma and surgically removed. Fortunately, this is not a serious problem. Chen Yuxi reminded that the above three types of skin cancer are related to ultraviolet radiation, so pay more attention to sun protection.
