Is this an early sign of skin cancer? (Photo)

Skin cancer, especially basal cell carcinoma or squamous cell carcinoma, often presents as a new, persistent, growing red or flesh-colored bump on the skin. These lumps or skin lesions are also often described as  non-healing sores. They may flake or bleed, but are not necessarily painful or symptomatic. It is very difficult to make a diagnosis from the picture you supplied. If you are concerned, your best bet is to see a dermatologist for a formal skin evaluation. The doctor may recommend a skin biopsy as part of the work up, or to confirm the diagnosis. Diagnosing and treating skin cancer early is recommended for the best outcome.

It's not possible to make a determination from the photos.  I would encourage you to see your dermatologist to see if they might want to do a biopsy.  Best of luck.
