What is Skin Cancer and Why Prevention Matters
Skin cancer is the uncontrolled growth of abnormal skin cells, mainly caused by prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. It is one of the most common cancers worldwide and includes three main types: melanoma, basal cell carcinoma (BCC), and squamous cell carcinoma (SCC).
Melanoma
The most serious type, known for rapid spread to other parts of the body. It often appears as an irregular, dark mole or spot.
Basal Cell Carcinoma (BCC)
The most common form, usually grows slowly and appears as a pearly or waxy bump on sun-exposed skin.
Squamous Cell Carcinoma (SCC)
Often develops on sun-exposed areas, appearing as a firm, red nodule or scaly patch; can be aggressive if untreated.
The incidence of skin cancer is rising globally, making prevention more important than ever. By adopting sun-safe habits and protecting your skin, you can reduce your risk and avoid the challenges of treatment.
Causes of Skin Cancer
Skin cancer develops when skin cells grow abnormally, often due to DNA damage caused by external factors. The most common cause is overexposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Repeated sunburns, especially during childhood, can significantly increase the risk later in life.
Other contributing factors include:
- Prolonged outdoor activity without sun protection
- Fair skin tone, which has less melanin and is more vulnerable to UV damage
- Family history of skin cancer
- Weakened immune system, which reduces the body’s ability to repair damaged skin cells
- Exposure to harmful chemicals like arsenic or industrial tar
- Age, as risk increases with cumulative sun exposure over time
By understanding these common causes, you can take proactive steps to reduce your risk of developing skin cancer. Early awareness is key to long-term skin health.
7 Effective Ways to Prevent Skin Cancer
Learn simple and practical steps to protect your skin and lower the risk of skin cancer. These prevention tips help you maintain healthy skin and promote long-term wellbeing.
Perform Regular Skin Self-Exams
Check your skin monthly for new or changing moles, spots, or lesions and consult a dermatologist if you notice anything suspicious.
Seek Shade During Peak Sun Hours
Avoid direct sun exposure between 10 a.m. to 4p.m., when UV rays are strongest.
Stay Hydrated and Maintain Healthy Skin
Drink plenty of water and use moisturizers to keep your skin healthy and resilient against sun damage.
Wear Protective Clothing
Seek for sun protective clothing with an Ultraviolet Protection Factor – or UPF. Clothing with UPF 50 means that one in 50 of the sun’s rays reach the skin.
Wear Sunblock Everyday
Just because it’s cloudy, doesn’t mean you should ditch the sunscreen. It is particularly important when UV index is the highest, which is usually between 11 a.m. to 2 p.m.
Get an Annual Checkup
Annual dermatology visits are a good way to keep track of skin changes. “The key is that skin cancer can look very harmless if you do not know what to look for.” says Dr. Angela Lamb, assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai.
Avoid Tanning Bed
The radiation from indoor tanning beds is sometimes stronger than radiation from the sun. This can cause skin cell mutations, explains Dr. Gary Goldenberg, assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai.
Stay Ahead of Skin Cancer with Proactive Care
Skin cancer is one of the most preventable forms of cancer when you take proactive steps to protect your skin. From daily sunblock use to regular skin checks, these simple habits can significantly reduce your risk and promote long term skin health. Stay informed, be consistent with your skincare routine, and make prevention a part of your everyday life.
While daily habits are crucial in preventing skin cancer, some individuals may also carry genetic traits that elevate their risk. At GHHS Healthcare, genetic screening services can help identify these inherited risks. Early awareness empowers you to take the right preventive actions and make informed health decisions for a safer future.
