Unfortunately, it is impossible to make a specific diagnosis over the Internet. One should always be concerned, however, when lumps or bumps in the skin fail to heal, and spontaneously bleed (especially if they are enlarging over time). A simple biopsy can usually make the diagnosis of a cancerous versus benign lesion of the skin. Therefore, if possible, you should seek medical care through whatever programs might be available in your area to uninsured patients (such as Medicaid or free clinics, for example).

Sincerely,
