You know your body better than anyone.

And while routine screenings (like mammograms, colonoscopies, and Pap smears) are the best way to catch cancer early, it’s also important to pay attention to changes — especially ones that are new, persistent, or unexplained.

The American Cancer Society and oncologists agree:
Some cancers do cause symptoms — but they’re often subtle and easy to miss.

Let’s explore 19 possible warning signs that warrant a conversation with your doctor — not panic, but awareness and action.

🧠 Why Awareness Matters

Cancer symptoms vary widely depending on type and location, but certain red flags appear across multiple forms of the disease.

🔍 The key is not to self-diagnose — but to recognize when something isn’t right and seek medical advice.
