What are the early symptoms of melanoma? How to prevent melanoma

What are the symptoms of early melanoma? You need to pay attention to changes in your body. If a mole on your body suddenly undergoes the following changes, you should go to the hospital as soon as possible, because with age or stimulation from external factors, some moles may become malignant.

Early symptoms of melanoma

1. The surface of melanoma patients is rough and not smooth, and is accompanied by scaly flaky desquamation, and sometimes there will be bleeding and exudation, which may be higher than the surface of the skin. This is an early symptom of melanoma.

2. Melanoma patients often feel itching, burning or tenderness in the abnormal area. When the above situations occur, it strongly indicates that you may have malignant melanoma. If there is any change in the skin mole, you should seek treatment in time. Excisional biopsy can be used to remove the malignant melanoma. These are the more common early symptoms of melanoma.

3. The early symptoms of melanoma include the following phenomena: the edges are often jagged and serrated, which is caused by the spread of the melanoma tumor or its own degeneration.

How to prevent melanoma

1. For pigmented nevi that occur in areas prone to friction, biopsy is generally used for pathological examination. The following areas of pigmented nevi require attention: For example, children's large hairy nevi on the waist are often rubbed and squeezed by the belt, so they should be removed as soon as possible. If it is difficult to remove all of them at once, then before malignant transformation occurs, the main part of the large hairy nevus can be removed as much as possible in the middle, and the two sides can be sutured. After the surrounding skin is loosened, the remaining part can be removed until the nevus is completely removed to prevent malignant transformation. Each specimen removed must be sent for pathological examination. If there is malignant transformation, it should be completely removed and then skin grafted.

2. It is not advisable to stimulate moles with corrosive drugs or complete freezing. If it is not frozen off once, it is very dangerous because trauma can stimulate moles and cause them to become malignant. It is reported that about 30% to 50% of malignant melanomas are related to external stimulation.

3. Pay attention to your diet:

(1) Eat more nutritious dried fruits and seeds, such as sunflower seeds, sesame seeds, pumpkin seeds, peanuts, raisins, etc. These foods contain a variety of vitamins, minerals, fiber, protein, and unsaturated fatty acids, which are good for the body.

(2) Eat more foods rich in vitamin A and vitamin C, such as green vegetables and fruits.

(3) Eat more foods that can inhibit carcinogenicity, such as kohlrabi, cabbage, shepherd's purse, cordyceps sinensis, etc. Among them, cordyceps sinensis has the most obvious anti-cancer effect.

(4) Avoid eating salted or smoked foods, especially burnt or charred foods, as they are carcinogenic.

(5) Stick to a low-fat diet and eat lean meat, eggs and yogurt regularly. (6) Food should be kept as fresh as possible and should not be eaten moldy or spoiled.
