Difference Between Mole and Melanoma
Difference Between Mole and Melanoma, human skin is prone to some abnormalities, such as the condition of moles and tumors, but because moles and melanoma are somewhat similar, many people tend to confuse the two, and now we are sharing the difference between moles and melanoma!
The difference between a mole and a melanoma1
1, they grow in different locations
The morphology of melanoma and a mole is almost the same, but there is a kind of malignant type of melanoma, which appears in some rare parts, such as the toes and the oral cavity, while the mole appears in the skin, the face, the body and the legs. Moles can appear on the skin, face, body, and legs. Moles are formed in the womb of the fetus, and melanoma is harmful to the human body, but moles are harmless to the human body, no matter how many moles there are. We need to recognize the difference between a mole and a melanoma and then treat it.
2. Their shapes are different
Ordinary moles are symmetrical on both sides, unlike melanoma. An ordinary mole does not have any effect on the surrounding skin. A mole is a spot on the face or the skin, although it will become larger. The surface of the mole may be uneven, but it usually does not rupture or bleed. In addition, it may ooze fluid locally, which may appear in different colors, feel painful when pressed, and have a watery substance inside. The surface of the melanoma is unbalanced and asymmetric, the edges are irregular and jagged, and the factors that lead to the formation of melanoma and nevus are completely different.
3, different colors
Ordinary moles are usually tan, brown or black, while malignant melanoma will be mixed with pink, white, blue-black on the basis of tan or brown. Among them, blue is the most ominous, and white suggests that the tumor has spontaneous degeneration. Nodular malignant melanoma is always blue-black or gray.
4. Their diameters are different
The diameter of a common mole is usually less than 5 millimeters, while the diameter of a malignant melanoma is more than 5 millimeters.
5. Melanoma can be raised
In some early melanomas, the entire tumor will be slightly raised.
6. They don't grow at the same rate
Some nevi that haven't changed in years grow significantly larger in a few weeks or months.
When you find a mole with size change, color change, lightening and bluing, and suddenly feel itchy or even painful, or the surface breaks down, or a large mole is surrounded by small moles in a satellite-like shape, you should go to the hospital to do a relevant examination. When a mole turns into melanoma, it cannot be identified with the naked eye, so you must go to the hospital to confirm the diagnosis.
The difference between a mole and a melanoma2
1, from the appearance of the distinction
Moles and melanomas can be distinguished from the appearance of the two halves of the mole are generally symmetrical, and the edge of the smoother, and the normal skin demarcation is very clear. While the shape of melanoma is no clear standard, may be asymmetric on both sides, the border is very untidy, generally jagged, and sometimes there will be flaking or oozing blood. Problems.
2. Distinguish from the color
Moles and melanoma can also be distinguished from the color, the color of the two is there is a certain difference, the color of the nevus is generally brownish yellow or black, although the melanoma may also be brownish yellow or black, but it will be mixed with some other colors, such as pink, white, blue-black. If the color of melanoma is found to be mixed with blue-black, this time should be taken seriously, because this color often indicates a high degree of malignancy.
3, from the size of the distinction
from the size of the distinction between moles and melanoma, the diameter of the mole is generally smaller, accounting for the skin area is not big. However, melanoma is much larger compared to a mole, and the diameter of a melanoma is usually larger than 5 millimeters, and due to its large size, it is easy to detect after it appears.
