The vast majority of moles, without stimulation, will not become cancerous from birth to death. But in the natural state, it is inevitable to be stimulated by the outside world.
Chronic stimulation and inappropriate treatment will greatly promote the transformation of nevus into melanoma. Clinically, most melanoma patients, because of improper treatment of nevus, lead to nevus deterioration.
According to clinical statistics, moles in some places are easy to deteriorate, such as heel, head, neck, limbs, eyes, under nails and labia minora. Theoretically, all cells that can produce melanin may become cancerous, but why are these parts easy to deteriorate?
Chronic irritation and inappropriate treatment are mentioned above. Improper treatment, usually by hand, and then can not get better care, so that melanocytes degenerate. There are also some mole removal programs of medical beauty institutions. If the excision is not clean, or the mole is treated locally in some ways, it is easy to promote cancer.
Chronic stimulation is easily overlooked, especially in some parts of the body that are often rubbed, such as feet and palms, which are usually rubbed more.
In addition, there is the neck, the collar is often rubbed, and the waist will be squeezed by the belt. Therefore, if there are moles in these places, we should pay attention to protection. Therefore, moles in these places are more likely to become cancerous.
It's not that we should be wary of moles in these parts, but because of this chronic stimulation. Pay attention to protection, reduce stimulation, and also reduce risks.
Ordinary moles with symptoms before deterioration are generally symmetrical, but irregular and asymmetrical, so we should pay more attention to observation.
When the nevus with clear boundary and smooth edge begins to become unclear and jagged, it should be checked in time.
There is also the judgment of size. Generally, the mole will not exceed 5 mm. If it is a big mole (greater than 5 mm), you should be vigilant. This is not to say that they are cancer. We should be alert to the possibility of cancer.
Color change is also a signal. We see that the common moles are black or brown, and when they begin to deteriorate, they will appear white, blue-black, or even pink. If you encounter such problems, you should seek medical advice in time.
It is best to do a formal comprehensive examination and preventive examination in the early stage, just look at it with the naked eye or check the whole body with a magnifying glass.
In some of the more important parts mentioned above, pay attention to protecting moles.
Normal moles, if not seriously affecting the appearance, try not to dig and try not to treat them with drugs.
Finally, there is sun protection. Ultraviolet rays can greatly promote the production of melanin. It is very important to prevent melanoma and skin cancer.
