It’s wise to learn about early warning signs in the body — but no single symptom means cancer, and many of these signs are caused by far more common, harmless conditions.
Still, certain patterns can signal when something needs medical attention.
Here are 16 general symptoms that doctors often recommend getting checked if they are unexplained, persistent, or worsening:

You should seek medical evaluation if:

It keeps getting worse
-
It interferes with daily life

You have multiple symptoms at once
Early evaluation leads to earlier treatment of any condition — cancer or otherwise.
