What is the medical term for a physician who treats skin issues?

The medical term for a physician who treats skin issues is dermatologist. Dermatologists specialize in diagnosing and treating a variety of conditions related to the skin, hair, and nails. They have extensive training in treating issues such as acne, eczema, psoriasis, and skin cancer, among others. Their expertise includes both medical and surgical aspects of skin care, making them the go-to professionals for any skin-related health concerns.

The other options pertain to different specialties: oncologists focus on cancer treatment, cardiologists deal with heart and vascular health, and podiatrists specialize in foot and ankle problems. Each of these specialists plays a crucial role in their respective fields but is not concerned with skin issues.
