Sep 5 The Importance of Full-Body Skin Exams and Early Skin Cancer Detection

Written by: Mariam Shahzad and Ihsaan Alam

Skin cancer is the most common cancer in the United States, making awareness and early detection extremely important. Although skin cancer can affect anyone, many people may not realize that it can develop on areas of the body that receive little or no sun exposure. A full-body skin examination allows a healthcare professional to examine the skin from head to toe and identify suspicious spots that a person may not notice on their own. According to the American Academy of Dermatology (AAD), skin cancer checks involve a visual examination of the skin, and full-body examinations are recommended whenever possible.

During a full-body skin exam, a dermatologist examines areas such as the scalp, face, arms, legs, back, feet, nails, and other less visible areas. Dermatologists may also use a dermatoscope to take a closer look at suspicious lesions. This is important because skin cancer can appear in many different forms, including a changing mole, a scaly patch, a sore that does not heal, or a spot that looks different from the surrounding lesions. The AAD recommends paying attention to spots that change in size, shape, or color, as well as lesions that itch or bleed.

Early detection is especially important for melanoma, which is the most serious form of skin cancer. The AAD explains that melanoma is less common than some other types of skin cancer but causes the majority of skin cancer deaths. When skin cancer is discovered early, treatment is generally more successful. Regularly examining the skin can therefore help identify suspicious changes before the disease becomes more advanced. In addition to professional examinations, individuals can perform regular self-examinations using the ABCDE warning signs of melanoma: asymmetry, border irregularity, color variation, diameter, and evolving appearance.

However, the importance of skin examinations should also be understood alongside current screening recommendations. The U.S. Preventive Services Task Force (USPSTF) states that there is currently insufficient evidence to determine whether routine visual skin examinations by clinicians provide more benefits than harms for asymptomatic adolescents and adults. This recommendation does not apply to people with symptoms, suspicious skin changes, or a personal or family history of skin cancer. The USPSTF also emphasizes that ultraviolet radiation from sunlight and indoor tanning is a major environmental risk factor for skin cancer.

Overall, full-body skin examinations can play an important role in recognizing suspicious lesions and encouraging early evaluation, particularly for people with increased risk factors or concerning changes in their skin. People should also become familiar with their own skin and regularly check areas that are difficult to see, such as the scalp, back, and bottoms of the feet. If a spot is new, changing, itching, or bleeding, it is important to have it evaluated by a healthcare professional. Combining awareness, self-examinations, sun protection, and appropriate dermatologic care can help individuals recognize potential skin cancers at an earlier and more treatable stage.
