What are the symptoms of mole cancer? 1. Junctional nevus is prone to cancer. How to determine whether it is a junctional nevus? Junctional nevus are generally brown or black, with a smooth, hairless epidermis, and some are slightly raised. Some of them may gradually disappear on their own, but some may turn into cancer, so you need to pay attention and observe them at all times. 2. Moles that are frequently rubbed are prone to cancer, such as those on the neck, waist, etc. 3. Early symptoms of mole cancer: Moles increase rapidly in number, become darker in color, and spread to the surrounding areas within a short period of time. The surface of the mole is prone to bleeding and forming blood scabs. The skin around the mole begins to itch and may even burn. 2. Randomly marking pigmented moles may induce cancer. Pigmented moles, commonly known as moles, exist on almost everyone. People have different attitudes towards pigmented moles. Some people don't care, some think it is unsightly, some think it is related to fate and luck, and some are always worried that it will turn malignant. Pigmented nevus is composed of pigment cells and is the most common congenital benign tumor of the skin and mucous membranes. It often occurs on the face, neck, back and other parts of the body. It varies in size, color, and shape. It can be divided into three categories: junctional nevus, intradermal nevus, and mixed nevus. Its nature and category are ultimately diagnosed by tissue section examination. When a pigmented nevus changes, such as sudden bulging or shape change, the edges of the originally round nevus become irregular, the boundary with the surrounding skin becomes unclear, and there are changes in size, skin surface, color, and hardness, you should pay attention to it, as it may be an early signal of a benign pigmented nevus becoming malignant. Many people worry about pigmented moles turning malignant, and it is not groundless. On the one hand, some pigmented nevi are easily confused with some skin malignancies and are often misdiagnosed with each other; on the other hand, some pigmented nevi do have a certain relationship with the occurrence of melanoma, so pigmented nevi should be given necessary attention and a dermatologist should be consulted for identification when necessary. 3. The symptoms of early canceration of moles should pay attention to the following points 1. Edge: The edge of the skin at the mole is jagged and serrated; 2. Surface: The surface of the mole is not smooth, and it is raised with flaky scaling, exudation or bleeding. At this time, you should be highly alert to the occurrence of melanoma; 3. Feeling of local itching, burning pain and tenderness may lead to the occurrence of melanoma; 4. The surrounding skin becomes edematous, loses its original luster or turns white or gray; 5. Color: the skin color of the mole is mixed, such as red, white or blue; 6. Other black nodules appear around the mole; 7. Local nodular or polypoid tumors or ulcers accompanied by exudation and bleeding. 4. Beware of ten types of pigmented moles that are prone to cancer. Do you feel scared when you see these? Everyone can find moles of varying sizes on their bodies. Some of these moles will not change for many years, while others may turn into malignant melanomas and endanger life. Of course, please rest assured that most moles have a low chance of becoming cancerous and generally do not need to be treated. However, if you find the following 10 types of moles on your body, you should pay attention! 1. Pigmented nevi usually appear between birth and 30 years old. The appearance of new pigmented nevi after the age of 30 should be regarded as suspicious. 2. People whose pigmented nevi are repeatedly infected. 3. When the pigmented nevus has a tendency to bleed. 4. Sudden and persistent itching occurs on the pigmented nevus. 5. There is an inflammatory red halo around the pigmented nevus, or satellite nevi appear around it. 6. The original hair on the pigmented nevus suddenly falls off. 7. The surface of the pigmented nevus is moist or has scabs formed. 8. When pigmented nevus is subjected to long-term and repeated friction or traumatic stimulation, there are potential factors for canceration. 9. When a nodule, ulcer or bleeding appears in the center of the pigmented nevus. 10. The darkening of a pigmented nevus is not an absolute indication of malignancy, because all pigmented nevus can turn black during sexual maturity and pregnancy. However, if any single mole becomes darker than other moles or becomes unevenly dark in a short period of time, or if it grows rapidly, it is an early sign of cancer. 5. Check out the symptoms of worsening moles. Xinhua Health Information says that everyone can find moles of varying sizes on their body. Some of these moles will not change for many years, while others can endanger a person's life. This is malignant melanoma. Generally, if a mole has the following changes, it indicates the possibility of malignant melanoma: 1. Mottled colors are often a sign of malignant lesions. Freckle-type and superficial spreading malignant melanomas often have red, white or blue mixed in with brown or black, among which blue is an ominous sign. 2. The edges are often jagged and serrated. 3. The surface is not smooth, generally very rough, and accompanied by scaly or flaky desquamation, and sometimes exudate or bleeding. 4. The surrounding skin becomes swollen or loses its original luster and turns white or gray. 5. There is often itching, burning or tenderness in the local area. When the mole continues to develop into an ulcerative lesion, it will be accompanied by exudation, bleeding, and the tingling or burning sensation will become more obvious. 6. Nodules may appear around the mole or accompanied by regional lymph node enlargement, which are manifestations of the middle and late stages. 6. Signs of mole canceration: What are the signs that mole cancer may turn into a malignant tumor and can be detected early? Many melanomas have some abnormal manifestations in the early stages of malignant transformation. When a mole on the body shows the following seven characteristics, you should seek medical attention in time: 1. Asymmetry: One half of the mole looks asymmetrical to the other half; 2. Irregular edges: The edges are irregular or have notches or serrations, unlike normal pigmented nevi which have smooth round or oval outlines; 3. Color change: Normal moles are usually single-color, while melanoma is mainly dirty black, but can also be brown, brown, brown-black, blue, pink, black or even white. 4. Diameter: Pay attention when the diameter of the pigmentation spot is larger than 5-6mm or when the pigmentation spot grows larger. Melanoma is usually larger than ordinary moles, so be careful of pigmented moles with a diameter greater than 5mm. Pigmented nevi with a diameter greater than 1 cm are best treated with excisional biopsy; 5. Protrusion: Some early melanomas may have a slight protrusion throughout the tumor. 6. Growth rate: Some moles that have not changed for many years may grow significantly larger within a few weeks or months; 7. If the hair that has been growing on the pigmented mole suddenly falls off, or if it breaks and is difficult to heal. 7. What are the symptoms before a mole turns cancerous? In addition, if a mole has the following changes, it indicates the possibility of malignant melanoma: 1. Mottled colors are often a sign of malignant lesions. Freckle-type and superficial spreading malignant melanomas often have red, white or blue mixed in with brown or black, among which blue is an ominous sign. 2. The edges are often jagged and serrated. 3. The surface is not smooth, generally very rough, and accompanied by scaly or flaky desquamation, and sometimes exudate or bleeding. 4. The surrounding skin becomes swollen or loses its original luster and turns white or gray. 5. There is often itching, burning or tenderness in the local area. When the mole continues to develop into an ulcerative lesion, it will be accompanied by exudation, bleeding, and the tingling or burning sensation will become more obvious. 6. Nodules may appear around the mole or accompanied by regional lymph node enlargement, which are manifestations of the middle and late stages. 8. What are the symptoms of worsening moles? Everyone can find moles of varying sizes on their body. Some of these moles will not change for many years, while others can endanger a person's life. This is malignant melanoma.
