A skin self-exam is a simple process where individuals check their own skin for any unusual changes or growths. This can help in early detection of skin issues, including skin cancer. It is recommended to perform these exams monthly, using a mirror to inspect all areas of the body, including hard-to-see places like the back and scalp. During a self-exam, look for new moles, changes in existing moles, or any spots that are asymmetrical, have irregular borders, or vary in color. If any concerning changes are found, it is important to consult a healthcare professional for further evaluation.
