Biomarkers are like warning lights in your body. They’re molecules, genes, or even physical signs that can tell doctors if something’s going wrong. Imagine a smoke detector – it’s a biomarker for fire. It doesn’t tell you exactly what’s burning, but it lets you know there’s a problem.

Here’s why biomarkers are important for disease detection:

• Early Warning: They can help catch diseases early, before you even feel any symptoms. This is crucial because many diseases are easier to treat when caught early.
• Accurate Diagnosis: Biomarkers can help doctors pinpoint the exact disease you have, which is important for getting the right treatment.
• Monitoring Progress: Once you’re diagnosed, doctors can use biomarkers to track how well your treatment is working.
