What are the common early symptoms of skin cancer?

Skin cancer is a common type of malignant tumor. However, for most patients, since they are unaware of the early symptoms of skin cancer , the disease continues to spread and eventually becomes life-threatening. So what are the main early symptoms of skin cancer? Let's take a look at the early symptoms of skin cancer.

Common early symptoms of skin cancer include squamous cell carcinoma and basal cell carcinoma. Squamous cell carcinoma is highly malignant and often occurs in the skin, mucous membranes and the junction of skin and mucous membranes in the head, neck, limbs, trunk and other parts. The early symptoms of skin cancer can form ulcers and grow in an invasive manner. When infiltrating deep tissues, it is often accompanied by purulent infection and lymph node metastasis. It is easy to evolve on the basis of xeroderma pigmentosum and senile keratosis. Basal cell carcinoma is more common in the elderly, and is prone to occur in the forehead, eye sockets, eyelids, nose, and around the ears. It is less malignant and grows very slowly. It is very common for the course of the disease to exceed 10 to 20 years. At the beginning, it is mostly a small thickened mass, which gradually bulges and infiltrates to the surrounding area, and rarely metastasizes. Skin cancer accounts for about 1.5% of all malignant tumors in my country, and the incidence rate in the south is higher than that in the north.

The incidence of skin cancer in my country is very low, but it is one of the most common malignant tumors in the white race, exceeding the sum of all other malignant tumors. The incidence of skin cancer in southern Australia is at least 650/100,000, and among Caucasians in the United States, the incidence of skin cancer is as high as 165/100,000, which is 100 times the incidence in my country. Among skin cancers, basal cell carcinoma is the most common, accounting for more than 60%. The early manifestations of various types of skin cancer are mostly erythematous lesions, accompanied by scaly desquamation or crust formation. It is not only difficult to distinguish its histological type by naked eye observation, but also easy to be confused with benign skin diseases such as psoriasis and eczema. Pathological examination is often required for diagnosis. Whether surgery, radiotherapy or other treatments, skin cancer has a good effect, and the cure rate can be over 90%.

The early symptoms of skin cancer are mostly erythematous or papular lesions slightly above the skin surface, often accompanied by scaly desquamation or crust formation on the surface. The symptoms are similar to benign skin diseases such as psoriasis, eczema, and inflammation. As the lesions further develop, some characteristic signs will appear, such as a shiny, translucent papular nodule with bleeding on the surface and telangiectasia, or a scar-like fibrous plaque with a smooth surface and no obvious telangiectasia, ulcers, or protrusions. Or there are small black spots in the lesions that merge with each other.

The above information is about the early symptoms of skin cancer. I hope you can spend as much time as possible to read these early symptoms of skin cancer.
