In people's cognition, the whole body, where there is a possibility of tumors, as for the nails of this kind of "bright", it should not be a big deal.
But, is that really the case?

Oh my God, malignant tumors can grow on your nails too! Moreover, such cases are not in the minority...
How can the nails dangling under the eyelids every day hide from the sky and let the tumor have "roots" and "buds"?
First, the nails grow black lines that are not painful or itchy
She had to cut off her finger to save her life
Ms. Feng, 53, works as a farmer at home for many years and grows corn for a living. Five or six years ago, she suddenly noticed that the thumb nail of her right hand inexplicably grew a "looming" black line, but it was not painful or itchy, there was nothing unusual.
And just like that, two years, three years, four years... This "stubborn" black line has not disappeared...
Since last May, her fingernail has cracked from the black line. After applying external medication treatment, not only was it not repaired, but all fell off, and an ulcer surface was formed, and the end of the skin at the root of the nail and the end of the finger appeared black pigmentation, which became like this:

Why are the good nails black and broken? She realized the seriousness of the problem, went to the hospital, after doing various examinations, the doctor diagnosed Ms. Feng's nail length "tumor": the nail mole turned into melanoma, and suggested that she have a finger amputation treatment.
Second, what "information" is hidden in this black line?
This "black line" on the nail is the most common symptom of nail mole. A female mole, in fact, is a kind of "mole", and the black mole on your body is no different, but the long position is more special. But once this mole becomes "melanoma", it is more terrible!

However, although the black line is a common symptom of the first female nevi, the black line and the female mole are not equal. Factors such as subungons, activation of melanocytes, onychomycosis, drug-induced pigmentation, and trace element deficiency may also occur, so a professional doctor is required to make a differential and comprehensive diagnosis.
The "blackening" of the black line is indeed not small! In life, in addition to the "black line", there are "white lines", "white spots" various nail problems, and "crescents" that carry a lot of pots... Is their appearance accidental, or is it a "gift" given by fate that has long been labeled as "disease"?
Those nail problems that you have been worried about, let's solve them today.
Third, nails without "crescent" are not healthy?
The scientific name of the crescent moon is A half moon or half moon marks, and there are some sayings circulating on the Internet, "It is healthier to have half moon marks" and "ten fingers should have eight to ten crescents as well".
Oh, let's just smile. What is a crescent moon and do you really understand?

The methyl group of nails is constantly producing new keratin cells, and the crescent moon is a collective of those living, white keratin cells. When these white, fat newborn cells push the cells of the previous generation to the nail root, the cells of the previous generation are squeezed more and more flat, gradually dying, hardening, and forming nails.
To put it simply, our nails are actually a pile of small cells that have died, and the crescent moon, that is, the new nails that have not yet hardened and become transparent, are the remnants of the transformation of keratin cells in the methyl region to keratin, and there is no more important health significance than other parts.
So why do some people have large crescents and some people don't have a crescent?

This is related to the metabolism of the body, and it varies greatly from person to person. As we age, the body's metabolism becomes slower and slower, so the number and size of the crescent moon decrease with age, and most adults can only see it on the thumb and index finger.
Some people are born with a relatively low methyl group or a slower nail growth rate, making the crescent moon hide and refuse to show its face, which will appear smaller. [1]
However, it should be noted that if the crescent suddenly becomes larger or smaller in the short term, or disappears and appears again, you need to be vigilant whether there is a problem with the thyroid gland.
Hyperthyroidism can make the metabolism of the whole body become fast, and nail growth is no exception. At this time, keratin, which has been a little hard but has not yet become translucent, will be very much, so that people who originally have no crescent will suddenly have a lot of full crescents, and people with crescents will become larger and larger. If it is hypothyroidism, it is just the opposite.
Fourth, what kind of color is a qualified nail?
For a healthy nail, the perynyroid skin should be smooth and soft, the nail bed should be ruddy, tough, smooth and shiny, and the thickness should be moderate.
Look at the color: pink pink color is the most positive, pink in the luster, that is the best product ~
Look at the texture: tough, feel tough and smooth to the touch, that is excellent.
In general, at first glance, it looks good in color and good texture, which is a qualified nail.
Five, those "strange" nails
If there are qualified, then there are unqualified ~ If the following abnormalities occur in the nails, then you must look at them a few times and pay attention to the changes in the situation:

The color of the nails appears abnormal:
White: We often say that there is no "blood color", which may indicate that you have too few red blood cells in your body's blood, or it may indicate liver disease, diabetes, hyperthyroidism, heart failure or a lack of nutrients in your diet.
Yellow: This yellow color is usually accompanied by thick fingernails and not very long. This is related to a disease called "yellow nail syndrome", which indicates lung disease.
Blue or purple: Doctors call this cyanosis, for example, we describe a person who is frozen and "lips are purple", which is "cyanosis", which is a phenomenon that indicates that your body's red blood cells cannot transport enough oxygen.

Abnormal lines or spots on the nails:
Faint red or brown lines. They are called flaky bleeding. Nail trauma or fungal infections can cause this phenomenon. This phenomenon can also occur with psoriasis, melanoma, or infection of the endometrium of the heart.
Thicker black or brown lines extending from the base of the nail to the tip may indicate melanoma, which is Ms. Feng's illness in the opening chapter, of course, not only black lines, but sometimes a black spot.

Abnormal changes in the shape of the nails:
Spoon shape. The nails are thinned and sunken in the middle, like a small spoon. This may indicate heart disease, trauma, lupus, hypothyroidism, or abnormal iron levels.
Pits or splits appear. Chronic inflammatory skin disease – psoriasis, which usually begins with the nails, can cause the nails to split or surfaces to appear dented.
The nails become thicker. Nail fungus, a contagious two! The infection may begin with thickening of the nails, grayish-yellow, taupe-brown or desquamation.
Clubbing. The tip of the finger "swells"! And the nails are curved and look like the lower end of a fallen spoon. This can indicate lung or heart disease, or even inflammatory bowel disease.
After reading these abnormal symptoms, the small partners are estimated to have silently stretched out ten fingers, if they find that there is exactly the same problem, it is estimated that they are panicked at this time.
stop! other! nervous!
Don't ignore the changes in the nails, but also don't draw conclusions immediately. The disease causes nail changes, but it is impossible to push back. So no doctor will diagnose a disease just by looking at the nails, and it must be based on more tests to determine if there is a problem.
In fact, you can see the small partners here in one breath, and see it, they are all the "true love" powder of the nails! Then finally, a warm reminder to the little fairies who like nail art
Nail art operations to go through a series of polishing, polishing, not only will destroy the protective layer of the nail surface, so that the nail is brittle and easy to break, serious may also cause paronychia. Problems such as lax disinfection during nail art and the quality of pigment products are even more health risks
