Classification of skin cancer and its symptoms

Skin problems are very common, but we don’t know much about skin cancer. The early symptoms of skin cancer are often not taken seriously. Today, we have asked our experts to explain the classification and symptoms of skin cancer. We hope that everyone will pay more attention to skin cancer and stay away from the harm it brings.

The early symptoms of skin cancer are very similar to those of some precancerous lesions such as solar keratosis and keratoacanthoma, and are very difficult to distinguish. Solar keratosis has rough, erythematous spots that are higher than the skin surface, and the surface is covered with scales. After the scales are removed, the erythematous spots often have no obvious protrusions. The early symptoms of this skin cancer are very similar to those of squamous cell carcinoma in situ, which presents as erythematous papules with clear boundaries and slightly higher than the skin surface, but the scales and crusts of the latter are more obvious, and the lesions are more essential.

The first type of skin cancer is malignant melanoma, which has four characteristics:

① Asymmetry: If the mole is asymmetrical in shape and its surface is not smooth, you should pay attention to it.

② The edges are rough and sometimes have cracks, which is the opposite of the smooth edges of normal moles.

③The colors are mostly mixed, especially brown or ink black, and sometimes red, white and blue.

④Mostly larger than 1/4 cm.

The second and third types of skin cancer are basal cell carcinoma and squamous cell carcinoma, which have four characteristics:

① If the growths appear suddenly on the parts of the body that are exposed to the sun, such as the head, neck, back of the hands, chest, back, etc., and do not disappear for a long time, you should pay attention to it. You should also be vigilant about acne that does not disappear for a long time.

② Bleeding. These two types of skin cancer will bleed after only a slight stimulation, while most common skin diseases do not have this characteristic.

③Scabbing condition: If the skin scabs for no reason, especially if the scabs do not disappear for a long time, you should pay close attention.

④ Pay attention to skin with scaly surface, secretions, or surface nodules or ulcers that do not heal.

The above is an introduction to the classification and symptoms of skin cancer. If skin cancer can be discovered by patients in its early stages, it can be 100% cured. If it is not discovered very early, it will be fatal. Therefore, early detection of signs of skin malignancy has its special significance.
