The difference between skin cancer and prickly heat

I believe that people know more about skin diseases than skin cancer. Although they are both skin diseases, they are very different. However, they also have a similarity, that is, they must be treated in time. So what is the difference between skin cancer and prickly heat? Let's learn about it together.

Early skin cancer often manifests 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. As the lesion develops further, 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, without obvious telangiectasia, ulcers, and protrusions. Or there are small black spots in the lesion that merge with each other.
Prickly heat rash is also called heat rash or red miliary rash. It is the most common acute skin inflammation in summer. Prickly heat rash is caused by blocked sweat pores and often occurs on the neck, chest, back, elbows, and fossa. Children may also experience it on the head and forehead. At the beginning, the skin turns red, and then needle-sized red papules or papulovesicles appear, densely packed in patches, some of which are purulent. Prickly heat rash is accompanied by severe itching and pain, and sometimes there are bursts of hot burning pain.
