Some time ago, we had a live broadcast of dermatology
The popularity of the live broadcast room can be described as "bursting"
In addition to caring about the problem of itchy skin, which is very common in winter
There are also concerns about moles, spots, and so on on the skin
No, hearing everyone's needs, popular science came
Moles and spots on your body are normal
But it's precisely these inconspicuous, seemingly normal things
It also often confuses "audio-visual" and makes people relax their vigilance
A dermatologist from the First Affiliated Hospital of Zhejiang University School of Medicine said
There is a type of tumour called basal cell carcinoma
Often "camouflaged" as spots or moles
If any of the following situations occur, you must be vigilant

The "matchmaker's mole" that has been growing for more than ten years is actually cancer?
About a decade ago, a black-brown "pimple" grew under the left side of her nose obliquely under a black-brown "pimple" in Lin'an, and at first she thought it was just a mole, so she didn't pay much attention to it. In addition, in the past few years, she has successfully connected several marriages, and the villagers all say that this is a "matchmaker mole", so even if this "mole" gets bigger every year, she doesn't feel that there is anything wrong at all.
"But the last two years have become too big and it looks a little ugly. Grandma Zhao said that the mole, which was originally only the size of a grain of rice, has become as big as a soybean this year, and it has frequent itching and unbearable itching, and it has been broken by her several times and has ulcerated. Recently, Grandma Zhao finally planned to go to a big hospital to get rid of the "mole" under the persuasion of her family, but she didn't want to find out the big problem.
"As soon as the old man arrived at the clinic, he said that he wanted to get a mole, but the first time I looked at it, I felt that something was wrong. After receiving the consultation, Luo Limin, deputy chief physician of the Department of Dermatology of the First Phase of the Headquarters of Zhejiang University, found that Grandma Zhao's "mole" protruded from the surface of the skin, and a black scab had formed in the middle due to repeated ulceration, and the boundary with the normal skin was not very clear, and the edge was like a "small pearl" in a circle. Luo Limin, who has rich experience in the diagnosis and treatment of skin tumors, immediately thought of a possibility: basal cell carcinoma.
The results of subsequent dermoscopy also preliminarily confirmed the doctor's suspicions. A few days ago, Deputy Chief Physician Luo Limin performed an expanded resection of a skin tumor for Grandma Zhao, and the postoperative pathology showed that it was basal cell carcinoma. At present, Grandma Zhao has been discharged from the hospital, and she needs to be rechecked regularly.

Be wary of such moles or spots
Long cancer is actually related to long-term sun exposure
"Basal cell carcinoma is one of the most common malignant tumors in dermatology, which can appear as black and brown nodules in appearance, which is very confusing, and many people will be confused with ordinary moles, age spots, etc. Deputy Chief Physician Luo Limin explained that our skin is epidermis, dermis and subcutaneous tissue from the outside to the inside, and the tumor cells of basal cell carcinoma are similar to the basal cells of the epidermis, and the basal layer is also distributed with melanocytes, and benign melanocyte hyperplasia is what we commonly call moles, so most people will be confused.
Doctors say that normal moles or age spots have smooth and clear edges, while basal cell carcinoma has pearl-like bumps on the edges, and it often has erosions, ulcers, scabs, etc.
Chief physician Qiao Jianjun, director of the Department of Dermatology of the First Hospital of Zhejiang University, said that the main cause of its disease is ultraviolet exposure (sun exposure), so the head, face, neck or back of the hands are the most common parts, especially the face, in addition, large doses of ionizing radiation, burns, scars, etc. may also induce the disease.
Don't panic, don't panic! Aside from the dose, you can't talk about "qualitative change", and to reach the carcinogenic level, it is necessary for the skin to be exposed to strong sunlight without any protective measures for a long time, so daily protection is very important.
Director Qiao Jianjun introduced that surgery is the standard treatment for basal cell carcinoma, as a low-grade malignant tumor, it grows slowly and rarely metastasizes, generally speaking, good results can be achieved after full-thickness resection, of course, regular reexamination and treatment according to the condition after surgery.

Experts remind that there are 3 points to remember for cancer prevention
Early detection and early treatment are more important than surgery to raise awareness of basal cell carcinoma. Doctor recommends:
1. Do a good job of skin sunscreen in daily life to prevent excessive sun exposure, especially the elderly should protect their skin.
2. If middle-aged and elderly people have "moles" and "spots" that grow rapidly in a short period of time on their faces, or are suspected of being "bad people", they should attach great importance to it, do not scratch or squeeze with their hands, pinch, needle picking, etc., and should seek medical diagnosis in time.
3. Low-grade malignant tumors will not metastasize ≠, no matter what, its properties are there, it is still locally destructive, and if it is delayed for a long time, it may also invade the maxillofacial bones and even the brain, so after a clear diagnosis, it is necessary to go to the specialist for scientific treatment.
