Skin cancer is a common disease, and there are many factors that can lead to the occurrence of skin cancer in daily life. So, what are the most important early symptoms of skin cancer? What are the signs of early stage skin cancer? 1. The incidence rate of skin cancer in China is low, but it is one of the common malignant tumors among white people, exceeding all other malignant tumors combined. Among skin cancers, basal cell carcinoma is the most common, accounting for more than 60%. Regardless of surgery, radiotherapy or other treatment methods, they all have good effect on skin cancer, and the cure rate can be over 90%. 2.Skin cancer mostly appears as erythematous or papular lesions slightly above the skin surface, and the surface is often accompanied by scaly flaking or scab formation, and the symptoms are similar to benign skin diseases such as psoriasis, eczema and inflammation. Further development of skin cancer lesions will show certain characteristic signs, such as a shiny, translucent papule-like nodule with oozing blood and dilated capillaries on the surface of skin cancer patients. Or a scar-like fibrous plaque with a smooth surface, without obvious capillary dilation, ulceration or elevation. Or there are black, fused dots within the lesion. These are the early symptoms of skin cancer. 3.Squamous cell carcinoma is often transformed from keratosis, mucosal leukoplakia and other precancerous diseases. It grows faster and forms ulcers as early symptoms of skin cancer. Some skin cancer patients can be nodule-like or cauliflower-like, with smaller invasion to the deep and movable base; some are butterfly-like, with more obvious infiltration to the deep and large destructive, often involving bones. Patients with skin cancer may be accompanied by malodor and pain. Regional lymph node metastasis is mostly seen. The authors encountered a giant squamous cell carcinoma of the head, which has incomparable malodor, more purulent secretions and easy bleeding; lymph node metastasis of the neck occurs. Since the early symptoms of skin cancer only spread locally and are not likely to spread to other organs with blood and lymph, early skin cancer usually does not cause death. Skin cancer patients have irregularly shaped lumps and discolored spots on the skin; lumps and discolored spots with jagged edges; lumps with mottled colors, black, brown, red and white; diameter more than 6 mm; ulceration and bleeding. These are also the early symptoms of skin cancer. If found, timely diagnosis and treatment are needed. Diagnosis methods of skin cancer Experienced dermatologists can generally diagnose whether the tumor on the skin is benign or not through the skin on the body surface. 1.For those who suffer from chronic skin diseases and certain occupations and workers who are exposed to radioactive substances, coal tar, asphalt, etc., if skin papules or small nodules occur, they should be alert to the occurrence of this disease. 2.The occurrence of hard nodules with elevated edges on the skin of body surface and the tendency to develop in all directions should alert to the possibility of skin cancer, especially for patients over 40 years old. 3.Histopathological examination has the value of confirming the diagnosis. If skin cancer is diagnosed, first of all, don’t panic, you must make a judgment on how to treat according to the specific situation and conduct multiple consultations. Especially if the tumor is large enough to compress nerves or near large blood vessels, conservative treatment is recommended. There are many treatment methods for skin cancer, including traditional Chinese medicine, surgery, radiation therapy and so on. Surgery is the preferred treatment for skin cancer, and post-operative herbal treatment. With proper surgical excision treatment plus Chinese medicine, the cure rate reaches 90% to 100%.
