If then character of your skin legion is brown or black, it is likely a kind of Pigmented BBC. These legions are mostly nodular and can be totally pigmented or appear in fractions of pigment. Again, as with any skin legion, you will want to consult your doctor as soon as possible. There are many other possibilities as to what this kind of legion could be other than skin cancer.
One way to diagnose your skin disease is by the appearance of it. If the legion you find is scar-like, it likely falls under the category of Sclerotic BBC. The characteristics of these particular legions are that they appear flat or even depressed, if the border of the legion is not well defined, or if the legion appears shiny–like a scar. However, something like this could just be a traumatic scar and not skin cancer at all.
If you legion is yellowish it may be what is called a Nodular BBC–the majority of these legions will be found on the face. Sometimes they are more pearly colored, they may have a rolled edge, stretching the skin will help you see the legion better, these legions are slow-growing and are almost always on the face. However, there are several other kinds of skin disease that could have similar appearance that is why it is recommended that you always consult your doctor when you find a legion on your skin.

The legion may have a fine scale, will appear perhaps with a thin, beaded pearly boarder surrounding it, these legions tend to have atropic centers.

As with any cancer, if the illness is identified soon enough, it is more effectively treatable–the same goes for other kinds of skin disease. So you do not want to put off diagnosis or the necessary treatment.
