Common Myths About Skin Cancer – Debunked by Dr. Shaun Segal

Skin cancer is one of the most common forms of cancer worldwide, yet it remains surrounded by dangerous myths and misconceptions. These myths often lead to delayed diagnosis, inadequate protection, and improper treatment. Dr. Shaun Segal, a highly respected skincare specialist in Australia, has treated numerous patients affected by skin cancer. In this blog, he debunks the most widespread myths to help you stay informed, protected, and empowered.

Myth 1: Skin Cancer Only Affects Fair-Skinned People

Reality: While individuals with fair skin have a higher risk due to lower melanin levels, people of all skin tones can get skin cancer. According to Dr. Shaun Segal, one of the most concerning trends is that skin cancer in people with darker skin is often diagnosed at a more advanced stage, making it more dangerous. Everyone, regardless of skin color, should undergo regular skin checks.

Myth 2: Skin Cancer Is Always Caused by Sunburn

Reality: It’s true that excessive UV radiation is the leading cause of skin cancer, but sunburn isn’t the only risk factor. Dr. Shaun Segal explains that skin cancer can also result from genetic predisposition, exposure to tanning beds, occupational hazards, and certain immune system conditions. Even people who rarely burn can still develop skin cancer from cumulative sun exposure over time.

Myth 3: If a Mole Isn’t Changing, It’s Not Skin Cancer

Reality: Not all skin cancers appear as changing or irregular moles. Some cancers develop as new growths or patches that may look harmless at first. Dr. Shaun Segal warns patients not to rely solely on visual changes. Any new or persistent skin lesion that doesn’t heal within a few weeks should be checked by a professional.

Myth 4: Skin Cancer Only Occurs on Sun-Exposed Areas

Reality: While the face, arms, and neck are common sites, skin cancer can occur anywhere — including the soles of the feet, under nails, and even the scalp. Dr. Shaun Segal advises patients to perform full-body checks and see a specialist annually. “It’s not just about what’s visible. Cancers can appear in surprising places,” he adds.

Myth 5: Sunscreen Completely Prevents Skin Cancer

Reality: Sunscreen is a powerful tool, but it’s not a shield that makes you immune. According to Dr. Shaun Segal, proper sunscreen application must be paired with wearing protective clothing, seeking shade, and avoiding midday sun. “Many people apply too little sunscreen or forget to reapply after swimming or sweating,” he notes.

Myth 6: Skin Cancer Is Always Easy to Spot

Reality: Not all skin cancers are visible to the untrained eye. Melanoma, for instance, can resemble a freckle or look completely harmless. Some types, like nodular melanoma, can appear suddenly and spread quickly. Dr. Shaun Segal emphasizes the importance of professional skin checks, even if everything looks fine to you.

Myth 7: Young People Don’t Get Skin Cancer

Reality: Skin cancer can affect people of all age groups. In fact, melanoma is one of the most common cancers in young adults, especially women under 30. Dr. Shaun Segal has seen many young patients who were shocked to learn that they had a cancerous lesion. Early education and prevention are key for younger demographics.

Myth 8: Skin Cancer Isn’t Serious

Reality: This is one of the most dangerous misconceptions. While many skin cancers can be treated successfully when detected early, some types like melanoma can spread to other organs and become life-threatening. “Don’t assume it’s harmless just because it’s on your skin,” says Dr. Shaun Segal. Timely diagnosis can make all the difference.

Myth 9: You Don’t Need to Worry About Skin Cancer in Winter

Reality: UV rays don’t disappear in winter. Even on cloudy or cold days, UV radiation can damage your skin, especially in Australia where UV levels can remain high year-round. Dr. Shaun Segal encourages people to make sun protection a daily habit, not just a summertime ritual.

Myth 10: Skin Cancer Is Always Caused by Outdoor Exposure

Reality: Surprisingly, UV exposure through windows or while driving can also increase risk. Indoor tanning beds are another major culprit. Dr. Shaun Segal urges individuals to be cautious about cumulative UV exposure in all settings — not just at the beach or on holiday.

Final Thoughts from Dr. Shaun Segal

Skin cancer myths can delay detection and lower awareness, putting lives at risk. According to Dr. Shaun Segal, knowledge is the best prevention. Regular self-exams, annual skin checks, and sun protection habits should be a part of everyone’s lifestyle — no matter your age, skin tone, or lifestyle.

“The earlier we catch it, the simpler the treatment. Never ignore changes in your skin, and when in doubt, get checked,” – Dr. Shaun Segal
