Black moles are something that everyone has, and people are generally not surprised. Most people's moles are benign, but also be wary of some moles that are disguised as melanoma. As a highly malignant tumor, melanoma is a deadly mole.
First, melanoma is often disguised as "black mole"
According to the 2021 "White Paper on the Behavior Of Chinese Melanoma Patients" released by 20 hospitals, the high incidence of melanoma patients in China is 50-69 years old, and 66% of patients are accompanied by ulcer symptoms and are prone to metastasis. The terrible thing is that one-third of the diagnosed patients have never heard of melanoma before.
Among them, only 13% of patients were diagnosed early, 59% of patients were in the middle and advanced stages of treatment, and the prognosis treatment effect was very poor, and 51% of patients with acromegadied type in China and 48% of patients with plantars were reached.
Long mole is a normal phenomenon, is due to the increase in melanocytes in the human body caused, ordinary black moles generally only affect the appearance, there will be no pain and itching feeling, do not need special treatment. Professor Cao Yang of the Cancer Center of the First Affiliated Hospital of Guangzhou University of Chinese Medicine suggested that to learn to distinguish between melanoma and black nevus, if you find black moles with fast growth rate, accompanied by ulcers, blurred boundaries, irregular shape, large area and variegated color, you should be vigilant against melanoma.
Identification of melanoma can also be preliminarily judged using the ABCDE method:
A refers to symmetry, generally benign moles are left and right symmetry, if you draw a line in the middle of the mole, left and right can not be symmetrical, or even strange shape, then pay more attention.
B refers to the boundary, the boundary is clear, smooth mole, generally do not worry too much. However, if the edges of the mole are uneven, such as the water of the fountain pen dripping onto the rice paper, and there is a feeling of halo around it, it should be paid attention to.
C refers to the color, the color of ordinary moles is uniform, abnormal moles vary in color, or black, blue, red and other color changes will occur.
D refers to the diameter, melanoma is generally larger than 6 mm; very small 1 mm, 2 mm moles do not have to worry too much, but pay attention to whether it will slowly become larger.
E-finger bulges: melanoma usually has lesion bulges and is progressive.
In addition, if it is a mole that is easy to rub, often sunburn, trauma and other parts, we must pay more attention, the moles in these parts are easily stimulated by friction, ultraviolet radiation, cell malignancy, etc., and the probability of cancer is very high.
Easy to rub parts: palms, soles of feet, under nails, nasopharynx, near the anus, and wearing bras, belts and other parts;
Areas where frequent sun exposure: head, neck;
Trauma site: such as the part that has been injured by smashing, stabbing, crushing and other injuries.
Reminder: Even benign moles may also appear cancerous, such as friction, damage, drug corrosion, scratching, etc. may stimulate the mole, causing cancer, so usually try not to stimulate the mole.
Second, the mole on the face can not be casually ordered
Many people with moles on their faces feel that they have a bit of an impact on the appearance and want to point it out, but Pang Litao, chief physician of the Department of Dermatology of the Third Hospital of Zhengzhou City, said that the black moles on the face may be the "camouflage" of malignant skin cancer, and it may be "quiet duty" in ordinary times, but if it is suddenly stimulated by freezing and lasers, it is easy to induce activity and cause cancer. Therefore, the doctor suggested: "The black mole must be identified to get rid of it, and it must not be 'used' without authorization." ”
Remove benign black moles also need to choose the right method, the general benign small black mole can be removed by the laser method, the freezing method to remove black moles is not feasible, for the risk of black moles with cancerous tendencies, it is recommended to use surgical resection method is more secure, even if you have undergone surgical resection, you must also appropriately combine pathological examination to continue treatment, can not be careless.
Everyone has large and small moles on their bodies, most of which are benign, but be sure to be wary of melanoma disguised as moles, especially when the moles appear to grow, ulcer, shape irregular, area enlargement, etc., be careful that melanoma sends a signal. For moles that grow on the face, remember not to mess around and be careful to cause cancer.
