As we age, taking care of our health becomes more important than ever, including the health of our skin. May is Skin Cancer Awareness Month, and it’s a timely reminder that skin cancer is the most common cancer in Canada, but also one of the most preventable.
Whether you’ve spent years gardening, travelling, or simply enjoying the outdoors, your skin has had a lifetime of sun exposure. That’s why older adults are more likely to develop skin cancer—and why regular checks and sun protection matter more than ever.
Why older adults need to pay attention
Many cases of skin cancer are linked to cumulative sun exposure over time. That means even if you’re not spending as much time in the sun now, your past exposure still puts you at risk.
There are three main types of skin cancer, with the two most common types (basal cell carcinoma and squamous cell carcinoma) in older adults often appearing on the face, ears, scalp, neck, and hands. The third type (melanoma), although less common than the first two, can often be more serious. As a result, it is important to be aware of the potential warning signs for all three.
Know the warning signs
Checking your skin regularly can help detect problems early—when they’re most treatable. Look for:
- New or changing moles or spots
- Sores that don’t heal
- Rough or scaly patches
- Spots that bleed, itch, or grow over time
Use the “ABCDE rule” as a guide for moles:
- Asymmetry (one half doesn't match the other)
- Border (edges are irregular)
- Colour (varied shades)
- Diameter (larger than a pencil eraser)
- Evolving (changes in shape, size, or feel)
If you notice anything unusual, speak with your healthcare provider or a dermatologist.
Ways to lower your risk
Protecting your skin doesn't mean avoiding the outdoors. It’s about being smart when you're out and about. Here are a few tips:
- Use sunscreen daily, even on cloudy days. Choose SPF 30 or higher.
- Wear a wide-brimmed hat, long sleeves, and sunglasses when you’re outside.
- Avoid sun exposure during peak hours: 10 a.m. to 4 p.m.
- Schedule an annual skin check, especially if you’ve had a lot of sun exposure or a previous diagnosis.
Skin cancer is common—but with a few simple habits, it’s often preventable and treatable. This Skin Cancer Awareness Month, take a few minutes to check your skin, talk to your doctor, and remind your loved ones to do the same.
After all, your skin has protected you for a lifetime—it’s time to return the favour.
