It is very important that skin cancer is recognized as early as possible in order for it to be treated effectively so that it does not cause much harm. In order for one to do that it is necessary that a person knows what skin cancer looks like whether it is on the face, arm, leg or nose. What skin cancer looks like on the face, arm, leg and nose will vary depending on the type of cancer it is. The symptoms for melanoma, basal cell carcinoma and squamous cell carcinoma are different and may appear different as well. Sometimes these marks go un-recognized and it is thus important to get regular skin check ups done.
