Should I worry about growth on my scalp?

[Matlisa]

About 1year ago a growth appeared on my scalp.  It has now gotten larger as well as is now changing color and has black/dark areas on top and some of the edges.  I am 48 and fair skin abd extremely freckled. I have a photo bug not sure if it can be posted

You should see a dermatologist immediately! I am a 63 year old female. I had a growth in my scalp for almost 2 years! I became concerned when it would not heal - no matter what I used to treat it. It appeared like a sore, but was not painful. A biopsy confirmed a squamous cell skin cancer! My doctor removed the growth in her office and I followed up with a cream which kills cancer cells. She seemed to be confident that it was only on the outer layer of my skin and had not spread. No further treatment was necessary. That was 4 years ago, and I haven't experienced any further problems. Make that appointment-now! Many blessings!
