1, diagnosis of skin cancer
1, the skin on the body surface appears induration and the edge bulges, which tends to develop around. Be alert to the possibility of skin cancer, especially for patients over 40 years old. This is a common diagnostic method for skin cancer.
2. Employees suffering from chronic skin diseases, engaged in certain occupations and exposed to radioactive substances, coal tar, asphalt, etc. If skin papules or small nodules appear, you should be alert to the occurrence of skin cancer.
3. Histopathological examination has important diagnostic significance for skin cancer. If you are diagnosed with skin cancer, don't panic at first. You must judge how to treat it according to the specific situation and consult in many ways. Skin cancer is generally not easy to operate, especially when the tumor is large enough to compress nerves or close to large blood vessels. Conservative treatment and diet therapy are recommended.
4, the diagnosis of skin cancer can check the feet, heels, toes, soles of the feet, and then take a mirror on the inside of your leg and keep moving to observe whether there are signs of skin cancer at the back of your leg. Once you find anything unusual, seek medical attention as soon as possible.
2. Early symptoms of skin cancer
There are signs or symptoms in the early stage of skin cancer, and the most obvious symptom is the changes in the skin, such as a long bag on the skin or an incurable ulcer. Different types of skin cancer have different symptoms. Some skin cancers may start with small smooth, pale or waxy lumps. Sometimes the lump will bleed or scab. Sometimes skin cancer begins with rough, dry or scaly red spots. It should be noted that skin changes do not necessarily indicate cancer. But if the above symptoms last for more than two weeks, you'd better see a doctor. Don't wait for these parts to hurt before going to see a doctor, because skin cancer won't hurt in the early stage.
The characteristics of early symptoms of skin cancer are summarized as follows: most skin cancers are uneven in color, such as brown, black, red, white or blue, and skin moles change color, so be especially vigilant. The margin is often jagged and uneven, which is caused by the tumor spreading around or self-degeneration. Its surface is not smooth. Usually rough with scaly or flaky desquamation. Sometimes there is oozing or oozing blood, and the focus can be higher than the skin surface. The skin around the focus may appear edema or lose its original skin luster or turn white and gray. Abnormal sensation: common local itching, burning sensation or tenderness.
3. Preventive measures for skin cancer
1, people with white skin are more likely to get skin cancer. Because people with fair skin have less melanin in their skin tissues, their skin is vulnerable to ultraviolet rays.
2. Long-term exposure to ultraviolet rays. People who like sunbathing but don't like sun protection are more likely to develop skin cancer.
3, sunburn from childhood, the probability of getting skin cancer will be higher when you grow up. The baby's skin is very delicate. The younger you are, the easier it is to get sunburned (or even blister), and the easier it is to become a risk factor for cancer when you grow up.
Long-term exposure to radiation may lead to skin cancer.
5. People with low immune function have a higher risk of cancer.
6. People who leave scars after being burned or scalded should pay special attention to whether the scars have changed. Scar comes from the damage of skin cells, and it is easy to get lesions over time.
7. Older people are more prone to skin cancer.
8. People with a family history of skin cancer, if the skin has unknown patches, it is best to go to the hospital for regular examination.
9. People with chronic poisoning are prone to squamous cell carcinoma. Well water content is relatively high, try not to drink too much well water.
10, people with chronic leg ulcers are prone to squamous cell carcinoma. In addition, human papillomavirus infection is also one of the risk factors.
1 1. People with many moles should always pay attention to whether the moles have changed, so as to avoid the lesions of the moles becoming melanoma.
