Crescent Conference Stroke , Crescent Neurosis, white spots are calcium deficiency... I don’t know when, nails became a kind of metaphysics, fingernails became the mirror of disease. Things as small as getting angry, bad breath, constipation, or as big as endocrine disorders, cardiovascular disease, etc. can all be seen through the fingernails.
Some of these are rumors, and some are indeed mysteriously related to diseases. There is even a possibility that life is at stake!
Black vertical lines appear on the nails, which may be onychomycosis, and can easily turn into melanoma.
Please note that melanoma is a fatal skin cancer that is extremely malignant. Patients with metastasis have a survival period of only 2-3 years!
According to media reports, 53-year-old Ms. Feng had a black line on her fingernails a few years ago. It slowly turned black and partially fell off. She was in unbearable pain when she touched water.
thought it was a common skin disease. After going to the hospital for examination, the doctor told her that she needed to cut off her finger to save her life. It turned out that Ms. Feng was suffering from melanoma. Since the diagnosis is still early, cutting off the fingers can save lives, otherwise the consequences would be disastrous.
Of course, not only black lines on the nails are nevus, but lack of trace elements, trauma, extrusion, etc. resulting in subungual bleeding will all lead to similar nail shapes.
At the same time, it cannot be said that "onychomycosis will definitely turn into melanoma." According to statistics, the probability of nail nevus becoming cancerous is between 1% and 2%, which is relatively low.
However, given the high mortality rate of melanoma, even if the probability is one in ten thousand, we must be vigilant! Therefore, if black vertical lines appear on your nails, don’t say anything and go to the hospital for examination as soon as possible!
. The ends of the fingers are swollen and the nails grow significantly downward - " clubbing fingers "
Many patients with lung diseases will have clubbing fingers. Relevant reports state that about 75%-80% of clubbing fingers are seen in lung diseases. [1]
A woman working as a real estate agency in Shenzhen poured tea for customers who came for consultation. The client accidentally saw that she had clubbed fingers, and based on her doctor's intuition, she suggested that she undergo a chest CT scan. It turned out to be lung cancer! Fortunately, it was discovered in time and the cancer cells did not spread, which can be said to be a blessing.
Therefore, if the ends of the fingers are swollen, special attention should be paid to whether the fingers are clubbed.
