While skin cancer is one of the most prolific forms of cancer around the world, and in 2023 ranked among the top five most common cancers in the UAE, May’s annual Skin Cancer Awareness Month is a great opportunity to spread awareness about the disease. After all, knowledge is power and the more you know about skin cancer, the better you’ll be equipped to prevent it, detect it and fight it.
Here, Dr. Ruhil Badiani from Cornerstone Clinic tackles some of the most important questions about skin cancer…
Firstly, what exactly is skin cancer and how does it differ from other cancers?
Skin cancer is one of the most common cancers worldwide, but it’s also one of the most preventable. It occurs when skin cells grow uncontrollably, often due to DNA damage caused by UV exposure. It can develop on any part of the body, even those not frequently exposed to the sun.
What are the most common causes of skin cancer?
Skin cancer is most commonly caused by excessive sun exposure, especially over long periods of time. Using tanning beds also significantly increases your risk. Repeated sunburns, particularly those that occur during childhood, can have a lasting impact. People with fair skin, light eyes, or light hair are more vulnerable due to lower levels of melanin. A family history of skin cancer may also increase your risk, as can having a weakened immune system.
Are there different types of skin cancer we should be aware of?
Yes, there are many different types of skin cancer each varying in origin, aggressiveness and treatment approach. The three most common types are: Basal Cell Carcinoma (BCC) is the most common and least aggressive, which appears as a pearly bump or flat, flesh-coloured patch; Squamous Cell Carcinoma (SCC) often appears as a red, scaly patch or sore that doesn’t heal, and can spread if left untreated; And Melanoma, which is the most dangerous type. This often develops in or near an existing mole and can spread if not detected early.
What should we be looking out for when checking our skin?
While skin cancer most commonly appears on areas frequently exposed to the sun, it can also develop in places you might not expect, including between the toes, on the soles of the feet, under fingernails and toenails, and even on the genitals or inside the mouth. These areas are often overlooked during self-checks, which can delay diagnosis. In particular, acral lentiginous melanoma, a rare but serious form of melanoma, is more likely to appear in these hidden spots and is more common in people with darker skin tones. That’s why it’s important to examine your entire body regularly, including hard-to-see areas, and to have routine skin checks for a thorough head-to-toe assessment.
Lastly, tell us what we can do in our day-to-day lives to help reduce the risk of skin cancer…
To reduce skin cancer risk, daily sun protection is essential. Use broad-spectrum sunscreen with SPF 30 or higher on exposed skin, even on cloudy days. Reapply every two hours if outdoors. Wear protective clothing like long sleeves, wide-brimmed hats and UV-blocking sunglasses to shield your skin from harmful rays. Choose tightly woven fabrics or those labelled with UPF (ultraviolet protection factor) for added safety. Avoid direct sun between 10am and 4pm, when UV rays are strongest. Never use tanning beds – they emit dangerous UVA radiation linked to skin cancer. Check your skin monthly for new or changing moles or spots, and schedule an annual skin exam with a dermatologist. These simple habits, practiced daily, offer strong protection against skin cancer while preserving skin health.
