I had a mole removed from my abdomen, then an excision done after finding pre-cancerous cells. My scar is raised & hard (Photo)

After surgery, scars continue to heal and change in a process called "remodeling" for at least a full year. That being said, your scar does seem to be quite raised. It looks like it is turning into what's called a hypertrophic scar or an early keloid. I would recommend a visit with the physician that performed the surgery to possibly inject it with kenalog (a steroid) to flatten it down at this point. Some physicians will offer a laser treatment for the scar as well, it's at least worth the mention when you see them. Good luck!
