I have a skin colored raised bump, almost appears like a mosquito bite on the dorsum of my right hand. It is not crusted or flaky like a basal cell cancer but am concerned it could be th beginning of a type of skin cancer. It is painless. Small and not slightly raised. Should this ce cause for concern. I am 33 and have had a bcc on my chest 3 years ago. I have had a lot of sun exposure, tan easily, but have a lot of miles and freckles
