Poor Oscar! His scrotum does look quite swollen and sore. Yes, unfortunately this could definitely be caused by testicular cancer, as this is a fairly common problem in older intact male dogs. He could also have an infection of the scrotum or testicles causing this swelling. I would recommend taking him to the vet to have this checked as soon as you are able to. He/she can take a biopsy if needed to help determine exactly what's going on, and may recommend surgical removal if cancer is suspected.
