Recognizing Early Signs of Skin Cancer

Understanding how to identify potential signs of skin cancer can be helpful for personal health awareness. Self-examination allows you to become familiar with your skin and notice any changes that may occur over time. While many skin spots are harmless, early recognition of unusual developments can be key. Here you can explore what to look for when examining your skin.

Spot Unusual Skin Changes

One of the first steps in self-monitoring for skin cancer is to look for new or unusual changes in your skin. This includes any new moles, spots, or growths that appear on your body. It is also helpful to observe existing spots for any alterations in their appearance. Changes in size, shape, color, or texture can be noteworthy. A spot that looks different from all others on your body, sometimes referred to as an “ugly duckling” sign, warrants closer observation.

Notice Persistent Skin Lesions

Skin lesions are areas of the skin that have an abnormal appearance compared to the surrounding skin. While many lesions, such as pimples or rashes, resolve on their own, some may persist. Pay attention to any patch of skin that becomes scaly, rough, or bleeds without a clear cause. Lesions that itch, feel tender, or cause pain should also be monitored. If a lesion does not heal within a few weeks, it may be time to see a doctor.

Track Moles and Growths

Regularly tracking your moles and other skin growths is a practical way to detect them early. Many professionals suggest using the ABCDEs as a guide to help identify features of concern in moles. This method can help you systematically check your moles for specific characteristics.

Asymmetry: One half of the mole does not match the other.
Border: The edges are irregular, ragged, notched, or blurred.
Color: The color is not uniform and may include shades of brown or black, or patches of pink, red, white, or blue.
Diameter: The spot is larger than 6 millimeters across (about the size of a pencil eraser), although some can be smaller.
Evolving: The mole is changing in size, shape, or color.

Keeping a photographic record of your moles can help you track these changes over time.

Watch for Nonhealing Sores

A sore or cut that does not heal is another potential warning sign. Most minor skin injuries, like a cut or scrape, will heal within a few weeks. A spot that repeatedly bleeds, scabs over, and then bleeds again without fully healing may require attention. These nonhealing sores can appear as a persistent, open wound or a crusty area on the skin. They may be flat or raised and can sometimes be mistaken for a simple pimple or blemish that won’t go away.

Protect Against Skin Cancer

Awareness and prevention are beneficial components of skin health. Protecting your skin from excessive sun exposure by seeking shade, wearing protective clothing, and using sunscreen can reduce your risk. Regular self-examinations help you stay informed about your own skin. If you notice any new or changing spots or have any areas of concern, it may be best to consult a qualified medical professional for an evaluation.
