Doctors Warn of Hidden Skin Cancer Spots

Three-quarters of one family has carried a diagnosis of skin cancer, a statistic that underscores the need for regular checks. Dr. Rhea Rogers, a board-certified physician, spoke with an aging expert and other specialists about how to spot the disease before it spreads. The group emphasized that skin cancer does not always appear on areas frequently exposed to the sun. Many people assume they are safe if their legs and arms look clear, but the condition can develop in harder-to-see locations.

Rogers listed specific areas where the disease often hides. These spots include behind the ears, between the toes, and underneath the nails. She noted that the scalp is a common site for growths because many people cannot see the back of their own heads. A partner or a medical professional can examine these blind spots during a routine visit. Patients should request a full-body exam to ensure these areas are covered. Some insurance plans treat an annual dermatology visit similarly to a well-woman exam, so patients should verify their coverage.

Identifying a potential cancer often starts with noticing a change in an existing mark. Rogers explained that doctors look for asymmetry in a mole. They examine whether the border is irregular or if the color shifts over time. They measure the diameter to see if it has grown. Finally, they track if the spot is evolving in appearance. Gerontologist Sam Cradduck added that even small changes matter. She stated that a difference of one millimeter can be a major indicator of a problem.

Patients should monitor for sores that refuse to heal. They should also watch for moles that bleed easily. Cradduck advised people to track whether a mole has grown or lost its symmetry. The specialists warned that these changes can happen to spots a person has had for years. A new spot is not the only sign of trouble. An old mark that alters its shape or color requires attention. Shiny bumps on the skin are another sign to report to a doctor.

Aging expert Amy O'Rourke shared her own experience with the disease. She visited a dermatologist regarding a brown spot on her cheek. The doctor performed a whole-body scan. That scan revealed a cancer on top of her head. She was diagnosed with squamous cell carcinoma. She underwent surgery to remove the growth. Rogers noted that squamous cell and basal cell cancers often appear as pinkish, itchy patches or non-healing sores. Melanoma typically looks more like a changing mole. Rogers warned that melanoma spreads quickly, making early detection vital.

Risk factors for skin cancer include fair skin, age, and family history. Rogers said the risk is likely a combination of genetic and environmental elements. She addressed the role of sun exposure in developing the disease. UVA and UVB light are invisible to the human eye. These rays can pass through glass windows. Intense, intermittent sunburns are usually linked to melanoma. Rogers corrected the common belief that people with darker skin do not need protection. She stated that everyone needs sunscreen to protect their cells and DNA from damage.

Beyond sunscreen, patients can use physical barriers for protection. Sun-protective clothing offers an additional layer of defense. Options include rash guards, sun guards, and UV clothing. Wide-brimmed hats also help shield the face and neck. Doctors recommend these measures for anyone who spends time outdoors. Patients should combine these habits with regular medical checks to lower their risk.

Rogers and her colleagues emphasized that the disease does not always look frightening. They noted that the subtle nature of early signs makes them dangerous. Patients should not wait for a spot to look alarming before seeking help. A doctor's exam can reveal issues that a mirror cannot show. Tracking changes over time allows for earlier intervention. The specialists encouraged patients to take a proactive approach to their skin health.
