Why do small black strips and novice points grow on the nails?

Many people say that nails are a mirror that reflects health. If the nails are abnormal, there are often problems with the body. Xiao Li recently found a black vertical line on his fingernail, and he ignored it at first. Later, when he was having dinner with his doctor friend, he talked about it. After reading it, his friend said that this is not a trivial matter, but it is a mole , it might be cancerous.

Xiao Li hurriedly went to the hospital for examination the next day. After the doctor's diagnosis , fortunately, it was only a benign mole on the nail. The doctor said, usually pay attention to avoid trauma, try not to smash it or grind a knife, and reduce the stimulation of external factors. Pay more attention to observe its shape change.

1. Black lines appear on the nails? Beware of Melanoma

1. What is a mother mole?

In the process of human growth and development, there will be some abnormal tissues, these are moles, and long moles are a very common phenomenon. A mother mole is a kind of mole. The most common one is black lines on the nails. It is clinically found that nails There is a small chance that a mother mole cancer will turn into a melanoma.

If the nevus on the nail begins to deteriorate, such as the black line changes for no reason, and the color starts to become uneven, it may be that the melanoma has begun to deteriorate , and timely surgical treatment is required.

2. Not all black nail lines are moles

Although the longitudinal black line is a common symptom of onychomycosis, it is not completely equated with onychomycosis. Nymphatic lines can occur at all ages, and are more common in dark-skinned people and adults. It is caused by the presence of melanin in the nail plate.

Generally speaking, the melanocytes in the nail matrix area are in a stable state, and there are two main reasons for the formation of the nail black line: activation of melanocytes and hyperplasia of melanocytes .

If melanocytes are activated, the number of melanocytes does not increase. Melanocyte activation can occur due to a variety of reasons and diseases, such as trauma, inflammation, infection, physical or chemical stimulation and other factors.

Melanocyte activation is more common in adults . Melanocytic hyperplasia is an increase in the number of melanocytes that leads to localized accumulation of melanin, resulting in the formation of nigra lines and is not uncommon in children and adolescents.

In addition, there are many causes of black lines, such as systemic pigmentary diseases, onychomycosis, drug-induced pigmentation, nutrient deficiencies (such as vitamin B12 deficiency), etc. Therefore, professional doctors are required for differential and comprehensive diagnosis.

3. How to judge whether the black vertical lines on the nails are melanoma?

(1) Melanoma is generally more common in adults.

(2) Width of black line: The black line of melanoma is generally larger than 3mm , and the color is different and the border is blurred.

(3) Black line changes: The black lines caused by melanoma change very quickly, and they will not improve under normal treatment.

(4) Common nail locations: melanoma black lines often appear on the thumb, index finger, toe and other positions.

(5) Periungual skin: In addition to black lines on the nails, melanoma can also cause symptoms such as darkening and erosion of the skin around the nails.

(6) Genetics: Melanoma has a genetic tendency, and those with family history should pay more attention.

4. Harm after the deterioration of a mother's mole

Experts say that after a naevus nevus turns into melanoma, if it is not treated in time, the cancer cells will rapidly metastasize and spread, first through lymphatic vessels, and then through blood circulation.

In a small number of patients, after extensive metastases, the skin of the whole body can become dark and grayish-blue. If metastases have occurred, the prognosis is poor. If early and timely surgical treatment can be performed, life can be saved. Late treatment is often difficult to control the development of the disease, so it is worthy of attention and vigilance.

2. Is the crescent plate on the nail a barometer of good health?

Have you noticed the "Crescent Moon" on your nails? Some people have bigger crescents, some smaller, some have eight to ten crescents, some have crescents only on their thumbs, and some don't even have one. Why is this? Some people say that crescent moon can reflect human health, is this true?

In fact, there is some basis for this.

What is the size of the "crescent" related to?

"Crescent moon" is related to people's qi and blood. Young people have strong qi and blood, and the "crescent moon" will be larger, and the old people will have a smaller "crescent moon". "Crescent moon" is clear and distinct, indicating that a person has more energy storage and is energetic. The "crescent" area of ​​healthy people accounts for roughly one-fifth of the nail. If the "crescent" shrinks, it is a signal of poor blood circulation.

If the "moon" on the nail disappears, it is a red flag for the body to have a disease. If the "crescent" of the thumb nail disappears, it indicates that there is a problem with the digestive system, indicating that the small intestine is blocked with feces. At this time, people are prone to choking water, and there is a possibility of cerebral thrombosis; on the contrary, if the "crescent" of the thumb is too large, it also indicates that the large intestine Stool stagnation, constipation, prone to cerebral hemorrhage.

"Crescent Moon" is clear and blurred, what is affecting it?

The pathological changes of the viscera tissues and organs can be reflected to the corresponding parts of the body surface along the meridian pathways to which they belong. Take a person's ten fingernails as an example, it contains the health information of the whole body.

Practice has proved that nails can reflect human diseases. According to the principle of hand diagnosis , normal nails should be pink, tough, smooth and shiny, and the "crescents" on the nails are clearly visible.

The more energetic, the whiter the "crescent moon", and the more blurred the "crescent moon". If the nails turn white when pressed and turn red without pressing, this is a sign of fullness of blood . If the nails turn white after pressing, and the redness recovers slowly after not pressing, this is a manifestation of lack of qi and blood.

How is the growth rate of the crescent moon affected?

If the crescent on the nail suddenly becomes larger or smaller, it is likely that there is a problem with your thyroid . The thyroid gland is one of the important immune organs of the human body, and the thyroid hormones it participates in regulating the metabolism of the human body.

During hypothyroidism, people's metabolism will become very slow, nails will grow very slowly, and the nail crescent will become smaller . On the contrary, if the thyroid function is hyperactive, it will speed up the metabolism in the body, and the crescent will suddenly become larger.
