Skin lesions refer to any abnormality, growth, or change in the skin's appearance or texture. Common types of skin lesions include moles, warts, cysts, rashes, bumps, and sores. These lesions can be caused by a variety of factors, including infections, allergies, immune system disorders, genetic factors, and exposure to environmental irritants. Research in the field of skin lesions focuses on understanding the underlying causes of different types of lesions, developing effective diagnostic tools and treatments, and exploring the association between skin lesions and various skin diseases, such as skin cancer. This research often involves dermatologists, pathologists, geneticists, and other healthcare professionals who specialize in skin disorders. Studies in this area can help improve the diagnosis and management of skin lesions, leading to better outcomes for patients.
