The Fight Against Skin Cancer: Where We Stand Today

Skin cancer is the most common cancer worldwide, with millions of new cases diagnosed every year. Despite its prevalence, the key to survival remains the same: early detection. Catching skin cancer early often means a quick outpatient procedure to remove a suspicious mole. But when detection comes too late, the cancer can spread and become life-threatening.

So how do we detect skin cancer today? Let’s look at the tools doctors and researchers use—and why innovation is still urgently needed.

1. Visual Checks

The process often begins with a simple but powerful tool: the trained eye of a dermatologist. During routine check-ups, doctors look for the “ABCDEs” of suspicious moles:

• Asymmetry

• Border irregularity

• Color variation

• Diameter larger than 6 mm

• Evolving over time

These rules of thumb help doctors identify which skin spots might need closer examination.

2. Dermoscopy

If something looks unusual, dermatologists use a device called a dermoscope. This handheld tool combines magnification and polarized light to reveal structures beneath the skin’s surface. Dermoscopy has improved the accuracy of diagnosis, reducing the number of unnecessary biopsies.

3. Biopsy – The Gold Standard

When suspicion remains, the next step is a biopsy—removing a small sample of skin to be analyzed under a microscope. This is currently the gold standard for diagnosing skin cancer. While effective, biopsies have downsides:

• They are invasive and sometimes painful.

• They require specialist access and lab work.

• Results can take days or weeks, delaying treatment.

4. Imaging & Emerging Technologies

In recent years, researchers have been developing non-invasive imaging methods, such as:

• Confocal microscopy – providing cellular-level images without cutting the skin.

• Optical coherence tomography (OCT) – using light waves to capture detailed skin layers.

• AI-powered apps – analyzing photos of moles and flagging those that might be dangerous.

While promising, many of these tools are still limited to specialized clinics or pilot studies.

Why We Need More Innovation

Despite progress, one major problem remains: accessibility. A patient in a large city may see a dermatologist within weeks, but in rural or underserved areas, wait times can stretch into months. By then, a fast-growing melanoma could already advance.

That’s why new, low-cost, accessible technologies matter so much.

At our nonprofit, we’re passionate about closing this gap. One project, Noma AI, uses artificial intelligence to help identify skin cancer from images, aiming to make early detection faster and more accessible. While no AI can replace a doctor, tools like this can act as an early warning system—empowering patients and supporting healthcare workers.

Looking Ahead

The fight against skin cancer is ongoing, but one thing is clear: early detection saves lives. By combining traditional methods with cutting-edge technologies, we have the chance to catch cancer sooner, treat it faster, and save more people from devastating outcomes.

And the best part? Innovation isn’t just happening in labs. Young scientists, students, and everyday people are stepping up with bold ideas. Together, we can make a future where early detection is not a privilege, but a reality for everyone.
