It is very difficult to recognize skin cancer. Most of the time it is so well hidden that you tend to over look it till it has reached a very advanced stage. Skin cancer can look like many things. It can look like a sore, spot, mole, lesion or any other type of skin abnormality.
The actual look of the skin cancer depends on the type of skin cancer that has infected you. Depending on whether it is basal cell carcinoma, squamous cell carcinoma or melanoma, the symptoms and marks vary. There are a lot of skin cancer pictures available on the World Wide Web and if you for some reason have a mark that matches any of them you should visit a doctor immediately.
