Where moles grow is a symptom and precursor of cancer

Where moles grow is a symptom and precursor of cancer Melanocytes are widely present in human skin. They can release melanin to help the body resist light radiation. In a normal person, melanocytes are evenly distributed, forming a healthy and stable skin color; when melanocytes are damaged, affecting local melanin secretion, it will cause vitiligo. Melanocytic nevus is a developmental malformation that is caused by the local aggregation of melanocytes due to some accident during their migration from the neural crest to the epidermis. Moles are the most common benign tumors in the human body. They are caused by an increase in melanocytes in the epidermis or dermis. Almost everyone has moles and they are all conscientious, but if you have the following moles, you must pay attention. Studies have shown that if there are more than 11 moles on the right arm, the chance of developing skin cancer is several times higher than normal. If there are more than 100 moles on the body, the risk of melanoma will be very high. Melanoma may appear anywhere on the human body, such as the arms, neck, legs, etc. Melanoma is actually a melanocytic nevus, which is basically no different from a normal mole. If it is discovered early and removed in time, it can be completely cured. The star Nicholas Tse once suffered from melanoma, but it was discovered in time and had a successful surgical removal. Everyone has various moles on their body, such as moles in the hair, seven moles on the forehead, moles on the forehead, moles on the forehead... Each mole represents a different meaning. There was a news story on the Internet recently, reporting that a middle-aged man has always believed that a mole on the back of his head is a lucky mole that represents wealth for life. Unfortunately, it was torn by the barber. When he went to the hospital to treat the wound, the doctor suspected the possibility of cancer. After a biopsy, it turned out to be a precancerous lesion. Judging from the result of this incident, the middle-aged man should thank the barber. If the lucky mole had not been shaved off, it might have turned into a bad mole. 2. What is melanoma? The lucky mole mentioned above is actually an early symptom of cancer caused by changes in melanoma in our body. So what exactly is melanoma? What we generally call melanoma is malignant and a type of cell tumor. It is not limited to appearing on the skin, but can also easily appear on the mucous membranes of the body and the choroid of the eyes. 3. Which moles are more likely to become melanoma junctional nevi? A mole that appears new or grows suddenly; Moles that grow on the palms, soles, waist, armpits, groin, shoulders and other areas prone to friction. However, even if a mole has the above characteristics, it does not necessarily mean that it will become malignant. According to statistics, the average adult has 15-40 melanocytic nevi. According to the 2007 statistical report on the incidence of malignant tumors, the incidence of melanoma in Chinese men is 0.84/100,000; and in women it is 0.72/100,000. This shows that the probability of a nevus turning into melanoma is very low. What we should really pay attention to is the series of symptoms in the early stages of malignant transformation. 4. Early symptoms of melanoma: The mole rapidly enlarges and becomes larger than 6 mm in diameter; Irregular and asymmetrical edges; The color is uneven, looks like a mixture of two or more colors, and has red edges; Scabs form on the surface; The affected area is itchy, painful, and ulcerated and bleeding; Swollen nearby lymph nodes Satellite lesions occur around it. If any of the above situations occur, you should go to a dermatologist for diagnosis immediately. 5. Causes of melanoma There is still no clear answer to the cause of melanoma, but it is mainly related to the following factors. The first is congenital causes, such as genetic inheritance and family history of melanoma. The second is skin pigmentation, such as overexposure to the sun, black cell nevus, etc. Another reason is the poor living environment. 6. Manifestations and pathological conditions: Generally, melanoma on the human body, such as the lucky nevus mentioned above, can easily become cancerous if it is stimulated for a long time. When malignant melanoma occurs in the body, there will be bleeding, itching, ulcers and pain. The occurrence of melanoma can also be seen from the appearance. So what does melanoma look like? First of all, the appearance and shape are asymmetrical and the edges are irregular. The edges of normal moles on the body are smooth, round or oval outlines. Secondly, the canceration of melanoma can also be seen from its color. The color of moles on a normal person's body will not change or change suddenly. Instead, if the color becomes darker, cloudy, or appears in a variety of different colors, it may be cancerous. Also, pay attention to the size of the mole. If the mole is relatively large or growing, such as when the diameter is larger than 5 mm, you need to pay more attention. If it gets bigger, it will be more dangerous. In addition, early-stage melanomas may appear raised, so be careful of raised moles on your body. 7. Common sites of melanoma Primary melanoma tumors in the human body account for 50%-70%, and most commonly occur in the limbs, such as the soles, toes, nails, etc., accounting for 50% of all melanomas. Melanoma also occurs on the mucosa, accounting for about 20%. It is easy to occur inside the eyes. Therefore, in daily life, you should pay attention to the moles on your body. If there are any changes, you need to seek medical attention and check in time. But we cannot just pay attention to black moles. We should also be more careful about other moles on the body to prevent diseases before they occur. 8. Where does a mole grow that increases the chance of getting sick? Cancer is a topic that no one wants to talk about, so what are the early symptoms of cancer? Can cancer be cured? Is cancer hereditary? Do you want to know about these questions? Let’s take a look at the early signs of cancer! New research shows people with more than 11 moles on their right arm have a higher risk of skin cancer. Experts say they have found a way GPs could detect more quickly whether a person is at risk of melanoma. Researchers say GPs could simply count the number of moles on a person's body proxy area, such as their arms, to determine their risk of melanoma. About 20 to 40 percent of melanomas arise from pre-existing moles, and having more than a hundred moles on a person's body indicates that the person is at a higher risk of melanoma. The researchers examined data from 3,594 female twins. Specially trained nurses at the hospital counted the number of moles in 17 areas of each subject's body. Skin texture, hair and eye color, and number of freckles were also recorded. The findings will be compared with a further study that includes data from both men and women. Scientists have found that the number of moles on the right arm is the best predictor of the number of moles on the entire body. People with more than 7 moles on their right arm are 9 times more likely to have more than 50 moles on their entire body than those with less than 7 moles on their right arm; 9. If someone has more than 11 moles on his right arm, it is very likely that he has more than a hundred moles on his body. Experts found that the area above the right elbow was particularly predictive of the number of moles on the entire body. The number of moles on the legs also predicted the number of moles on the body, while the number of moles on a man's back also predicted his risk of skin cancer. The researchers concluded: "We show that individuals with more than 11 moles on their right arm are likely to have more than 100 moles on their body, which in turn indicates a high risk of melanoma." The findings have important implications for primary care, allowing GPs to quickly determine the overall number of moles a patient has on the most visible part of the body. This will mean that more patients at risk of melanoma can be detected and monitored. He said the findings would be useful because having lots of moles on the body usually means a person is at high risk of melanoma. Other indicators of melanoma risk include having red or blond hair, fair skin, light-colored eyes, or having been sunburned in the past. But existing moles cause less than half of all melanoma cases. So it's important to understand what's normal for your skin and tell your doctor if you have any changes in the size, shape, color, or feel of moles or common patches. Don't just look at your arms, either; melanoma can appear anywhere on the body, most often on the torso in men and on the legs in women. Identifying health conditions through breathing is an old tradition, and the traditional Chinese medicine theory of looking, smelling, asking and feeling includes this diagnostic method. However, Western medicine has only a short history of diagnosing diseases in this way. Thank you for reading Where moles are symptoms and precursors of cancer. I hope it helps you.
