What is the role of a dermatologist?

The role of a dermatologist is to specialize in the diagnosis and treatment of conditions related to the skin, hair, and nails. This includes a wide range of issues such as acne, eczema, psoriasis, skin cancer, and various other dermatological disorders. Dermatologists are trained to understand the complex structures and functions of the skin and are equipped to provide both medical and surgical interventions for a variety of skin conditions. Their expertise extends to cosmetic issues as well, helping patients improve the appearance of their skin and manage conditions that can affect self-esteem.

The other options pertain to different fields of medicine. Diagnosing heart conditions falls under cardiology. Managing cancer treatments is typically the domain of oncologists. Handling mental health issues is the purview of mental health professionals such as psychiatrists or psychologists. Each specialty focuses on particular aspects of health, but the unique focus of dermatologists on skin, hair, and nails distinctly defines their role in healthcare.
