The growth of nails is closely related to the health of other organs of our human body. If there are black lines on your nails, there are many factors, which may indicate that you are tired recently and your liver and kidney functions are impaired. Another reason to be vigilant is that this may also be an early manifestation of cancer.
2 What kind of nail black line represents cancer? Nail nevus can turn into melanoma.
The most common symptom of nail nevus is nail black line, which is a deep black line on the nail. Many people disagree, but this disease can easily become melanoma. Melanoma, also known as malignant melanoma, is a malignant tumor derived from melanocytes. The five-year survival rate of early malignant melanoma can reach more than 60% after surgical treatment. However, if not found and treated in time, the five-year survival rate of advanced melanoma is less than 5%, and it is very easy to metastasize and relapse.
Therefore, early detection and examination of nail black line is of great significance for the prevention and treatment of melanoma.
3 How to distinguish the nail nevus from other nail black lines 1, it can be seen that the nail nevus is often single and dark in color; Other nail black lines can be single or multiple, and the color is very light, often accompanied by tiny vertical black lines at the edge of the nail, which can be distinguished by careful observation.
2, look at the changes, in addition, the nail bed of the nail nevus will change, first black stripes, and then it will widen and turn black as time goes by; The black lines of other nails are generally normal, and the color, width and length will not change.
4 How to avoid the canceration of nail nevus 1, not * * * Use nail clippers * * Use nail clippers may be infected with blood-borne bacteria, such as hepatitis C virus and Staphylococcus aureus, so don't lend nail clippers easily.
2. Don't file your nails frequently before manicure. After the nail epithelium is filed off, the protective effect is weakened, and it is easy to be infected by microorganisms such as bacteria, fungi and viruses, which may develop into paronychia. Moreover, nail polish for nail art contains many chemicals, which may cause cancer. In addition, the stimulation of nails will make nails more sensitive and easy to cause cancer.
Don't be exposed to ultraviolet rays for a long time, which is the main cause of malignant melanoma. Therefore, we need to pay attention to sun protection every day and avoid going out under strong sunlight for a long time. It is recommended to wear a sunscreen hat and sunscreen when going out.
4. Avoiding external stimuli, trauma and chronic stimuli is one of the reasons for the malignant transformation of pigmented lesions. There are also cases of sudden spread and death caused by incomplete stimulation such as corrosion and electrocautery in the treatment of benign nevus.
5. About 30% ~ 50% of malignant melanoma is related to external stimuli. In order to avoid canceration, we suggest that patients should remove nail nevus at one time as soon as possible, which is relatively safe and reliable.
6. Avoid the existence of estrogen receptor in pregnant melanoma cells, indicating that it has a certain relationship with malignant melanoma. The formation of melanin is due to the existence of a complex enzyme containing cu 2+ in melanocytes, which catalyzes the oxidation of complex acids into melanin. Glutathione in human body can indirectly inhibit the activity of arginase, while estrogen and progesterone can resist the action of glutathione, resulting in increased melanin production. Therefore, it is considered that endocrine has a certain relationship with the formation of melanosis.
Generally speaking, pregnancy will make the estrogen in the human body increase rapidly, and promote the existing melanoma cells to become cancerous.
