Cancer often develops silently, but our bodies have a remarkable way of sending early distress signals—subtle changes that are easy to dismiss as "nothing." Learning to recognize these whispers can be the key to catching cancer at its most treatable stage. Here are five warning signs that deserve attention and a conversation with your doctor.
Remember: Having one of these symptoms does not mean you have cancer. Most often, they're caused by benign conditions. But they're important signals that something in your body has changed and needs evaluation.
1. Unexplained Weight Loss
What to notice: Losing 10 pounds or more without trying—no change in diet, exercise, or stress levels.
Why it matters: This can be an early sign of several cancers (pancreatic, stomach, esophageal, or lung). Cancer cells can alter your metabolism, or tumors can interfere with how your body absorbs nutrients.
When to act: If you've lost a significant amount of weight without explanation over 3-6 months, schedule a check-up.
2. Persistent, Unexplained Pain
