Teach you how to detect skin cancer in early stage
Skin cancer is relatively slow to metastasize compared with other tumors, so it has not been paid much attention to, which often delays the best time to seek medical treatment. Therefore, early detection of signs of skin malignancy has its special significance. Here we introduce the early characteristics of skin cancer and the methods of self-examination, so that you can go to the hospital for timely diagnosis.
I. Skin-like cancer is a malignant melanoma with four characteristics.
1. Asymmetry. Moles with asymmetrical shape, if the surface is not smooth, should draw attention.
2. Rough edges and sometimes cracks, which are the opposite of normal moles with smooth edges.
3.More often have mixed colors, especially brown or black, sometimes also mixed with red, white and blue.
4.More than 1/4 cm in size.
The third type of skin cancer is basal cell carcinoma and squamous cell carcinoma, whose characteristics are three.
1. If the skin is exposed to sunlight, such as head, neck, back of hands, chest, back, etc., if the growths are protruding and do not disappear for a long time, attention should be paid to them. You should also be alert to acne that does not disappear for a long time.
2. Bleeding condition. These two types of skin cancer will bleed only after slight irritation, while most of the general skin diseases do not have this feature.
3.Crusting condition. If the skin crusts for no reason, especially if the crusts do not disappear for a long time afterwards, it should be highly noted.
4.If the skin surface is scaly with secretion or the surface is hard or broken and does not heal, it should be noted.
It should also be noted if the skin shows certain unusual phenomena, such as a point shining, shining like a pearl, or visible microvessels.
Self-examination steps.
1, facing the mirror (the same below), the whole body naked, starting with both arms, check the palms, fingers, between the fingers, forearms and back arms. Then raise your arms, bend your elbows and carefully check the inner side of the small arms and joints.
2.Check the front of the body: face, neck, chest, abdomen and mons pubis area and legs.
3.Check the side of the body: hands up, check the left half first, then the right half.
4, turn your back to the mirror and hold a small mirror in your hand to look at the back of the neck, back, buttocks and both arms locally. If it is not convenient, ask one of the spouses or a close friend to help check it.
5. Ask someone to ruffle the hair with a comb so that you can check the skin of the head for any suspicious areas. If it is a male, you can also touch it slowly by yourself when the hair is shorter.
6.Sit down and check your feet, heels, toes and soles, then take a mirror and place it on the inside of your legs and keep moving it around to observe if there are signs of lesions on the back of your legs. Once you find abnormalities, seek medical advice as soon as possible.
