The difference between melanoma and mole Causes of melanoma

Many people have several moles, whether on their faces or bodies, they really exist on us. Some people have moles on their faces, which may affect their appearance. If they grow next to their mouths, they may be teased as matchmaker moles, which is embarrassing. In fact, moles may be melanoma, which may threaten your life and health. So what is the difference between melanoma and moles?

1. The difference between melanoma and mole <br/>Melanoma is asymmetrical, with unclear borders, some are ragged or have gaps, and are uneven. The color is generally black, brown, or other different shades of pigment. Melanoma does not maintain a fixed size, but also changes in size and diameter over time. Moles are different from melanomas. They are relatively smooth in color, do not change in diameter, and have no abnormal characteristics.

2. Causes of melanoma <br/>If you have a lighter skin color, your ability to resist ultraviolet rays is weak. If you are exposed to the sun for a long time, it is easy to develop melanoma. Generally speaking, moles can be transformed into melanoma. If you are exposed to ultraviolet rays for a long time, there is a 25% chance that they will be transformed into melanoma. If there are many family members who have experienced melanoma, then you will also have a high probability of developing melanoma, and the risk is higher. In addition, people with genetic defects will also increase the risk and need to make relevant skin biopsies.

3. How to prevent and treat melanoma <br/>First of all, do not expose your skin to the sun and use sunscreen to avoid the occurrence of melanoma. For treatment, surgical resection is also used, which can be removed cleanly without leaving any sequelae. However, if the melanoma is large, check whether there are signs of metastasis in the nearby lymph nodes. If there is no metastasis, it can be cured. Even if it is metastatic, biological therapy, radiotherapy, etc. can still be used to improve the survival rate.
