How to tell if a mole will become malignant

Disease analysis: If the color of the pigmented nevus suddenly changes from light to dark, and there is local bleeding, ulceration, redness and swelling, etc., the area increases, and satellite-shaped pigmented dots appear on the edges, and the patient has mild itching, burning, pain or pinprick sensation locally, he should seek medical attention in time to prevent malignant transformation.

Guidance: It is recommended that you go to the hospital to check the cancer, and then do further **, if you want to prevent moles from becoming in the first place, you must first take sun protection measures. German scientists have recently found that sun exposure is associated with the development of malignant melanoma on the surface of the mole; The number of moles a parent has on will help how many moles their child will have in the future.

Therefore, in addition to observing the changes of moles in daily life, we should pay more attention to sun protection.

You can observe if there is a sudden increase in size in a short period of time, whether the surface of the mole is uneven, and if so, you should go to the hospital for examination.

If you look at it for a long time, you should pay attention to any changes that you have.

It is also necessary to rule out external factors, such as allergies, etc.

If there is a big change, it is easy to turn into cancer.

Pigmented nevus is very common, there are a lot of ** on everyone's **, these pigmented nevi rarely attract people's attention, some people think that pigmented nevus has no effect on the human body, don't pay attention to it, in fact, pigmented nevus will not only affect the appearance, but also have the possibility of lesions, threatening the patient's life, so, ?Early detection of malignant signs of pigmented nevi and prompt surgery** can prevent the occurrence of melanoma.

Once a certain malignant transformation signal is found, it should be surgically removed in time, and its ** rate is very high. The following eight changes are signs of malignant transformation of pigmented nevi: 1. Color change Benign pigmented nevi have a uniform color, dark brown or black, and no other variegation.

In addition to dark brown and black, red, pink, white, and blue can appear, and this color can spread from the edge of the mole to the surrounding area normally**. 2. Size change Benign pigmented nevi are generally less than 6 mm in diameter, and if they suddenly enlarge or continue to increase, they may be a sign of malignant transformation. 3. Change in shape Benign nevi is round, with a clear boundary between it and normal **, with regular edges, flat or slightly raised.

In malignant transformation, the edges are irregular, may be serrated or other shapes, and the pigment often spreads and extends and is normal around it**. At the time of malignant transformation, the shape is no longer round, but becomes asymmetrical and irregular. Fourth, the bulge changes Benign nevi are generally flat or slightly raised, such as a sudden obvious bulge**, especially on the original flat pigmented nevus, which is often a sign of malignant transformation.

5. Surface changes The surface of benign pigmented nevus is smooth and flat, and there are no other pathological phenomena, such as desquamation, erosion, exudate, crust, ulceration, bleeding, etc., which are often malignant transformation signals. 6. Changes in the surrounding ** When the pigmented nevus is in a benign state, the surrounding ** is completely normal, such as flushing and swelling, especially when there is a small "satellite pigment fast" around the mole, it should be considered as the beginning of malignant transformation. 7. **Sensory changes Benign pigmented nevi feel the same as normal**, if there is abnormal sensation, such as itching, tenderness, and pain, you should pay close attention to the tendency of malignant transformation.

8. Change in hardness Benign moles have uniform hardness and soft texture, such as suddenly becoming "soft" or "brittle" in texture, most of them are signs of malignant transformation. ?Anyone with benign pigmented moles, especially those over the age of 40, should pay close attention to the changes in the moles, and moles that grow on the back, waist, buttocks and other parts of the body can be observed in a mirror, or ask a doctor to check them regularly.

If you have any of the above symptoms, you should go to the hospital for medical treatment in time.

Under normal circumstances, the malignant transformation of the mole is mainly manifested as rapid enlargement, spread, and even ulceration in a short period of time, so it is very likely to be malignant. It is necessary to seek medical attention in a timely manner.

It is what we call dysplastic moles in technical terms, moles with dysplasia. The characteristics of these moles are that they are irregular, relatively large, more than 5 mm, irregular shape, and unclear borders, and such moles are prone to malignant transformation, which is called dysplastic moles.

In general, most moles are benign, and a very small number of moles have the possibility of cancer, especially the fast-growing moles, which have broken and bleeding, and the moles that do not heal for a long time are more likely to become cancerous. If there is no change in the mole, if there are no symptoms, it is considered benign and does not need to be treated, if the mole grows rapidly, local pain, itching, and bleeding indicate that the possibility of cancer is relatively large, and surgical removal is required to prevent cancer

Congratulations, I watched the health show The doctor said that a hairy mole is benign and will not become cancerous, but when the hair falls out, you should pay attention to it, as long as your mole does not grow on the part that is easy to rub into, it will be fine.
