Did you know that about 1.6 million Americans discover a lung nodule on their chest X-ray or CT scan every year? That’s like finding the population of Philadelphia! While most lung nodules turn out to be harmless, it’s natural to feel worried when you hear about one. Think of a lung nodule like a small dot on a huge canvas – we need to figure out if it’s just a random spot or something that needs attention.

What is a Solitary Pulmonary Nodule?

Imagine a small marble inside your lung. That’s similar to what a solitary pulmonary nodule (SPN) looks like on an X-ray or CT scan. Just as not every cloud means rain, not every nodule means trouble. Our calculator helps you understand your risk factors better.

Why Use This Calculator?

Just like checking the weather forecast before planning your day, understanding your nodule risk can help you:

• Make informed decisions about further testing

• Know what to expect

• Plan your next steps with your doctor

• Feel more in control of your health journey

Ready to check your nodule risk? The calculator is waiting below. Remember, it’s just one piece of your health puzzle, like a compass pointing you in the right direction. Use it as a starting point for discussions with your healthcare team.
