Early warning signs of cancer can be subtle, so attention should be paid to any new or unexplained changes that may lead to early diagnosis. Professor Peter Johnson, national clinical director for cancer in the National Health Service in England, stated, "Cancer symptoms and early warning signs can vary greatly; some are less obvious than others. But it is important to know what is normal for you, so you can spot any changes. If you have any concerns, or if something in your body does not seem right, you should consult your general practitioner, especially since early cancer diagnosis can save your life."
Here are the important signs that require contacting a doctor:
- Shortness of breath.
- Recurrent infections.
- Unexplained night sweats.
- Unexplained bruises or bleeding.
- Blood in urine.
- An unexplained lump.
- Presence of blood in stool.

- Stomach issues (discomfort or diarrhea).
- Unexplained pain.
- Feeling of fatigue and discomfort.
- Heartburn or indigestion.
- Unusual, pale, or fatty stools.
