Skin cancer is the most common cancer in the United States. It’s easy to assume you know the basics about protecting your skin, but there are still dangerous misconceptions that can leave you more vulnerable to skin cancer.
May is Melanoma and Skin Cancer Awareness Month, and we’re taking this opportunity to debunk some of the most common skin cancer myths we hear. Maria Scouros, MD, and our team at Houston Cancer Institute in Houston and Katy, Texas, specialize in melanoma and skin cancer treatment, and these myths can create a false sense of security that prevents people from taking proper precautions or seeking timely medical care. Here are the facts you need to protect yourself.
Melanin provides some natural protection against ultraviolet (UV) radiation, and skin cancer is less common in people with darker complexions. But it’s a common misconception that only fair-skinned people get skin cancer.
You can develop skin cancer regardless of your skin color, and this dangerous myth can put people with darker skin tones at serious risk. In fact, when skin cancer is diagnosed in people of color, it's often detected at later, more advanced stages because neither patients nor healthcare providers expect it.
You need sun protection, regular skin checks, and prompt evaluation of suspicious lesions regardless of your skin tone. Pay special attention to areas less exposed to sun like your palms, soles of your feet, under your nails, and inside your mouth, where skin cancers in darker-skinned people are more likely to develop.
Intentional tanning, whether indoors or outdoors, significantly increases your risk of melanoma and other skin cancers, so it’s easy to assume skin cancer only affects people who deliberately seek out UV exposure. Unfortunately, everyone is at risk from everyday sun exposure that accumulates over their lifetime.
Going outside exposes you to UV radiation that damages your skin cells' DNA, and you don't need to experience sunburn for damage to occur. Plus, certain skin cancers can develop in areas that never see the sun, and some forms are linked to factors beyond UV exposure, including genetics, immune system suppression, and exposure to certain chemicals.
When it’s applied correctly, broad-spectrum sunscreen is one of your best defenses against skin cancer. But it’s really just one component of comprehensive sun protection. No sunscreen blocks 100% of UV rays, and most people don't apply enough or reapply frequently enough for maximum effectiveness.
You need a multilayered approach for maximum protection. Seek shade during peak sun hours between 10am and 4pm, wear protective clothing including long sleeves, pants, and wide-brimmed hats, use sunglasses that block UV rays, apply broad-spectrum sunscreen with SPF 30 or higher, and reapply every two hours or after swimming or sweating.
It’s important to regularly check any preexisting moles you might have, but skin cancer doesn't always develop from moles. New spots, patches, or growths that appear on previously clear skin can be cancerous. Basal cell carcinoma (BCC), the most common skin cancer, often looks like a pearly bump, a red patch, or a sore that won't heal, not like a typical mole at all.
Instead of focusing solely on moles, you need to watch for any new or changing spots on your skin. Look for sores that don't heal within a few weeks, scaly red patches, shiny bumps, or pink growths with raised edges.
The ABCDE rule for melanoma — asymmetry, border irregularity, color variation, diameter larger than a pencil eraser, and evolution or change over time — helps you identify suspicious lesions, but any new or evolving skin change warrants professional evaluation.
It's true that many skin cancers are highly curable when caught early, but that doesn’t mean they’re not serious. Melanoma can be aggressive and fatal. It's one of the most common cancers in young adults and can spread rapidly to other organs if not treated promptly.
Even nonmelanoma skin cancers like basal cell and squamous cell carcinoma (SCC) can cause significant disfigurement if left untreated, especially when they develop on your face. Advanced cases can invade deep tissues including bone and cartilage. Taking skin cancer seriously and seeking prompt treatment for suspicious lesions is critical for the best outcomes.
This Melanoma and Skin Cancer Awareness Month, don't let myths compromise your skin health. Everyone needs sun protection, regular self-examinations, and annual professional skin checks regardless of skin tone, sun exposure habits, or family history. Early detection saves lives, so schedule your skin cancer screening at Houston Cancer Institute online or by phone today.
