The Dangers of Skin Cancer and How to Prevent It

Return to The Wellness Wednesday Menu

Most of us enjoy a sunny day—whether we’re relaxing at the beach, going for a run, or just soaking up some vitamin D. But while sunshine can lift our spirits, it also carries a hidden danger: skin cancer. It’s the most common form of cancer in the United States, and while it’s often treatable when caught early, prevention is by far the best strategy.

May is Skin Cancer Awareness Month and so in this week’s Wellness Wednesday, we’ll break down the types of skin cancer, what makes it dangerous, and most importantly, how you can protect yourself and your loved ones from its risks.

What Is Skin Cancer?

Skin cancer happens when skin cells start growing uncontrollably. This usually results from DNA damage caused by ultraviolet (UV) radiation from the sun or tanning beds. There are three main types of skin cancer:

  • Basal Cell Carcinoma (BCC): The most common and least dangerous. BCCs grow slowly and rarely spread, but they can cause disfigurement if not treated.
  • Squamous Cell Carcinoma (SCC): Less common but more likely to spread than BCCs. They often appear on sun-exposed areas like the face, ears, and hands.
  • Melanoma: The deadliest form of skin cancer. Although it accounts for only about 1% of cases, it causes the vast majority of skin cancer deaths because it spreads quickly to other organs if not caught early (CDC).

The Alarming Statistics

Skin cancer is more common than all other cancers combined. In fact, 1 in 5 Americans will develop skin cancer by the age of 70 (Skin Cancer Foundation). Each year, over 5 million cases are diagnosed in the U.S., and the numbers are rising.

Melanoma, in particular, has become increasingly common. According to the American Cancer Society, about 104,960 new melanomas will be diagnosed in 2025, and approximately 8,430 people will die from it.

The good news? Most skin cancers are preventable, and when caught early, they’re highly treatable.

Risk Factors You Should Know

Understanding what increases your risk can help you take action. Here are the top contributors:

  • Excessive sun exposure: Especially without sunscreen.
  • Tanning beds: These emit harmful UV radiation, increasing your risk significantly.
  • Fair skin: People with lighter skin tones, freckles, and red or blonde hair are at higher risk.
  • A history of sunburns: Even one blistering sunburn in childhood can double your chances of developing melanoma.
  • Family history: If a close relative had skin cancer, your risk is higher.
  • Weakened immune system: Whether from illness or medications, this can increase vulnerability.

What Makes Skin Cancer So Dangerous?

For many people, skin cancer doesn’t seem as scary as internal cancers. After all, it’s visible and often grows slowly. But that thinking can lead to dangerous complacency. Here’s why you should take it seriously:

  • Melanoma can be deadly if it spreads beyond the skin. It often invades the lymph nodes and internal organs quickly.
  • Late detection reduces survival rates. The five-year survival rate for melanoma is 99% when it’s caught early, but it drops to 32% if it spreads to distant organs.
  • Non-melanoma skin cancers like BCC and SCC can still be disfiguring, especially when they occur on the face or neck.

In short, ignoring a suspicious mole or avoiding sunscreen could have life-altering consequences.

 

How to Prevent Skin Cancer

Thankfully, protecting yourself from skin cancer doesn’t mean avoiding the outdoors altogether. Here are simple, science-backed tips to keep your skin safe.

1. Wear Sunscreen Daily

This might sound like a broken record, but it’s your first line of defense. Choose a broad-spectrum sunscreen with SPF 30 or higher, and apply it 15 minutes before sun exposure. Don’t forget often-missed spots like your ears, the back of your neck, and your feet.

Reapply every two hours—or more often if you’re swimming or sweating.

2. Avoid Tanning Beds

Indoor tanning dramatically increases your risk of all types of skin cancer. According to the World Health Organization, just one session can raise your melanoma risk by 20%, and the risk goes up with each use.

Simply put: there’s no such thing as a safe tan unless it comes from a bottle.

3. Cover Up

Clothing is an underrated sun shield. Wear long-sleeved shirts, wide-brimmed hats, and UV-blocking sunglasses. Some clothing is even designed with UPF (Ultraviolet Protection Factor) fabric that offers superior sun protection (Skin Cancer Foundation).

4. Seek Shade During Peak Hours

The sun is strongest between 10 a.m. and 4 p.m. Try to stay in the shade during these hours or plan outdoor activities for the early morning or late afternoon.

5. Check Your Skin Regularly

Early detection is key. Do a monthly skin self-exam and look for any new or changing moles, freckles, or spots. Use the ABCDE rule to spot suspicious moles:

  • Asymmetry: One half doesn’t match the other.
  • Border: Irregular, blurred, or jagged edges.
  • Color: Multiple colors or uneven shades.
  • Diameter: Larger than a pencil eraser (about 6mm).
  • Evolving: Changes in size, shape, or color over time (American Academy of Dermatology).

If anything looks off, see a dermatologist. Don’t wait.

6. Schedule Annual Skin Checks

Even if you don’t notice anything strange, it’s wise to get a professional skin exam once a year—more often if you’re high risk. Dermatologists can spot signs you might overlook.

7. Teach Sun Safety Early

Skin damage begins in childhood. Teaching kids to wear sunscreen, hats, and protective clothing sets the stage for a lifetime of healthy habits. Some studies suggest one blistering sunburn in childhood doubles the risk of melanoma later in life.

Busting Common Myths

Let’s clear up a few misconceptions:

  • “I tan easily, so I don’t need sunscreen.” False. Tanning is a sign of skin damage, and even darker skin tones can develop skin cancer.
  • “It’s cloudy, so I’m safe.” Up to 80% of UV rays can penetrate clouds (Skin Cancer Foundation).
  • “Sunscreen is just for summer.” UV rays are present year-round, even in winter and at high altitudes.

 

Final Thoughts

Skin cancer might be common, but that doesn’t mean it’s inevitable. With a few mindful habits—wearing sunscreen, avoiding tanning beds, covering up, and checking your skin regularly—you can enjoy the sun safely and significantly reduce your risk.

It’s easy to take our skin for granted. But it’s our body’s largest organ and our first line of defense. Let’s protect it like it protects us.
