First, the symptoms show that the incidence of malignant melanoma is higher than that of men, and the mortality rate of male patients is higher than that of women. The tumor site of female patients is in the leg, while that of male patients is in the back and head and neck. The original pigmented nevus suddenly appeared for unknown reasons, and its shape or color changed rapidly. In the original pigmented nevus, new dark brown patches suddenly appear, and some malignant melanomas also have obvious pigmentation, generally without obvious symptoms such as pain or itching. With the continuous increase of liquid, the surface of the plaque is easy to bleed due to damage, and there are irregular pigment halos around it, and local liquid monitor lizards increase, with obvious fracture and repeated healing. There is no obvious accompanying state in the early stage, and there may be weight loss and other manifestations in the later stage.
Second, the treatment of melanoma is highly malignant and easy to metastasize. Therefore, early judgment and timely and reasonable treatment are extremely important. Early local surgical resection is the best way to strive for cure, which is suitable for advanced patients. Early surgical resection is malignant melanoma. At present, there is no main treatment. At present, chemotherapy drugs in colleges and universities are mainly used for postoperative adjuvant therapy or for advanced patients. It is necessary to exercise moderately, increase patients' physical immunity, avoid excessive exercise, actively carry out psychological treatment for patients, and relieve depression and anxiety.
Thirdly, it takes a long process to distinguish whether a mole will become melanoma. First of all, you can look at the comparison of moles. Normal moles are generally completely symmetrical, but if it is melanoma, there will be asymmetric moles. It can also be judged by looking at the edge of the mole. Usually moles are smooth and clear. If the edge is uneven and blurred, it may be melanoma.
