British doctors remind women who like to wear cold towing in summer to be alert to the health hazards of these shoes. Because cold towing usually exposes a large area of skin to the sun, it can increase the risk of skin cancer.
Anthony Kontos, a London foot doctor, said that a hospital in London has received at least two cases of foot skin cancer in the past 3 months. One patient had malignant skin tumors in his feet for two years, but he had been mistaken for contusion.
Kontos said: "our feet are wrapped in shoes for most of the year. If they suddenly wear sandals in hot weather, their feet are particularly vulnerable to sunburn." It is quite popular nowadays, but this kind of shoe makes the large area of the skin directly exposed to the sun. However, people usually do not remember to apply sunscreen or regular examination to their feet, so it is easy to unconsciously increase the risk of skin cancer.
Cancer affecting the foot is manifested as a foot tumor, usually formed under the sole of the feet, toes or toenails. Because such tumors do not cause pain or discomfort, they are difficult to be perceived by patients.
Now many people know many kinds of sunscreen programs. This message reminds you that there is a blind area in your sunscreen program. From now on, you should pay attention to it. The consequences of sunburn feet are very serious. Don't stingy your darling sunscreen on your feet.
　　 Little knowledge: white skin is not exposed to sunlight. 
To say that white skin is not only exposed to sunburn, but that the lighter the color of skin and eyes is, the easier it is to get sunburn and the greater the possibility of skin cancer. Therefore, skin cancer is more prevalent in the west, because Westerners have lighter skin. Prolonged exposure will certainly increase the risk of skin cancer, but short exposure to sunlight, such as sunbathing on the beach and drying skin blister, may also increase the risk of skin cancer. Exposure to skin cells is a long-term accumulation of damage, so middle-aged and elderly people with skin cancer may be larger.
