5 warning signs of cancer developing in the body

When Should You See a Doctor?

Consider speaking with a healthcare professional if you notice a symptom that:

  • Is unexplained
  • Persists for an extended period
  • Gets progressively worse
  • Is accompanied by other unusual symptoms
  • Causes significant changes in your normal health

Do not try to diagnose yourself based on a list of symptoms found online.

A medical professional can evaluate your symptoms, medical history, and risk factors and decide whether further testing is necessary.

Early Attention Matters

Cancer includes many different diseases, and the symptoms can vary greatly depending on the type and location of the cancer.

Some cancers cause noticeable symptoms early, while others may not cause obvious symptoms until later.

This is one reason why recommended screening tests are important for people who are eligible for them.

Screening can sometimes detect certain cancers or precancerous changes before symptoms appear.

The Bottom Line

Five signs that should not simply be ignored are:

  1. Unexplained weight loss
  2. Persistent fatigue or weakness
  3. Unusual changes in the skin
  4. Persistent or unexplained pain
  5. New or unusual lumps or swelling

These symptoms do not mean that you have cancer.

They can occur for many different reasons, most of which may not be cancer-related.

However, if a symptom is unusual, persistent, unexplained, or getting worse, it is sensible to have it evaluated rather than ignoring it.
