Do you know the early symptoms of skin cancer?

Early stage skin cancer often presents as erythematous or papular lesions that are slightly higher than 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. Today we will analyze the difficulties in this regard in detail.

As the lesion progresses, certain characteristic signs may appear, such as a shiny, translucent papule-like nodule with bleeding on the surface and telangiectasia, or a scar-like smooth fibrous plaque without obvious telangiectasia, ulceration, or protrusions, or small black spots that fuse with each other in the lesion.

The above characteristics of skin cancer are very similar to the symptoms of certain precancerous lesions such as solar keratosis and keratoacanthoma, and it is difficult to distinguish them. Solar keratosis has rough erythema that is higher than the skin surface, and the surface is covered with scales. After removing the scales, the erythema often has no obvious protrusion. This is very similar to the erythema-like papules with clear boundaries and slightly higher than the skin surface of squamous cell carcinoma in situ, but the scales and crusts of the latter are more obvious, and the lesions are more substantial. Keratoacanthoma often occurs in exposed areas to sunlight. Without any warning signs, smooth red nodules will quickly appear within 2 to 3 weeks. There is a keratin embolus in the center, and dilated capillaries can be seen at the edge of the nodule. The nodules of squamous cell carcinoma that is distinguished from it are not smooth, and the edges of the nodules are translucent.

Because it is extremely difficult to distinguish between precancerous lesions and skin cancer, when you suspect a disease is skin cancer, it is best to do a pathological biopsy to confirm your judgment. The above is the knowledge we have prepared for you today. I hope it will be helpful to everyone.
