How often should I check my skin for signs of skin cancer?
There is no specific universal schedule mandated for the frequency of skin self-exams, but the core medical recommendation is to perform regular, ongoing skin checks to identify any changes in the appearance of existing marks or the appearance of new ones [1]. The primary goal of this examination is to become 'familiar' with the normal appearance of your skin, which allows you to notice any unexplained shifts in color, size, or shape early on, as early detection significantly increases the chances of successful treatment [1], [4].
Why is regular examination essential?
Skin cancer, including basal cell carcinoma and squamous cell carcinoma (non-melanoma types) and melanoma, is one of the most common types of cancer [1]. These cancers often develop in areas most exposed to sunlight, such as the face, neck, hands, and arms [1]. If left untreated, these tumors can grow and spread to neighboring tissues or other organs, making periodic self-monitoring the first line of defense that prompts you to take early medical action [1], [2]. You can read more about this topic via the Non-Melanoma Skin Cancer: Early Detection guide (Arabic) to understand how to assess your personal risk.
How to perform a skin self-exam accurately
To conduct an effective self-exam, dermatologists recommend following a comprehensive methodology to ensure no area is overlooked. Start by using a full-length mirror to examine the front and back of your body, raising your arms to look at the sides [4]. Do not ignore hard-to-see areas, such as the scalp, by using a hand mirror to part your hair and examine the skin underneath, in addition to checking the buttocks and the back of the neck [4]. Also, be sure to check often-forgotten areas, such as between the toes, the soles of the feet, under the arms, and the palms of the hands, as skin cancers can appear anywhere [4].
Signs that warrant consulting a dermatologist
During the exam, do not look only for "moles," but look for any unusual skin changes. Signs of basal and squamous cell carcinomas include a sore that does not heal or persists for a long time, or skin patches characterized by being raised, smooth, shiny, or pearly in appearance [2]. Signs also include a hard, scar-like spot (which may be white, yellow, or waxy to the touch), or a red, scaly, and irritated area that does not respond to conventional moisturizers [2]. If you notice any of these symptoms, or if there is a skin mark that has changed in size, shape, or texture, you should consult a specialist dermatologist to evaluate the need for a skin biopsy to confirm the nature of the cells under a microscope [2].
Risk factors and the need for specialized screening
While anyone can develop skin cancer, the need for vigilance increases in higher-risk groups, such as people with fair skin, those who have spent long periods in the sun or suffered repeated sunburns, or those with a family or personal history of skin cancer [1], [2]. Anyone with suspicious skin marks or changes in skin appearance is advised to see a doctor for evaluation [1]. Advanced age, especially over 50, is a major risk factor for most types of cancer, and the likelihood of developing it increases with age [2]. In cases with specific hereditary risk factors, such as Gorlin syndrome, a doctor may recommend more specialized periodic screenings [3].
