19 Warning Signs That Cancer Is Growing in Your Body

Frequent constipation, diarrhea, or a change in stool appearance, especially if these changes persist, can be a sign of colon cancer. Similarly, changes in bladder habits, such as frequent urination or blood in the urine, can point to bladder or kidney cancer.

6. Difficulty Swallowing
Difficulty swallowing, or feeling like food is stuck in your throat, can indicate cancers of the throat, esophagus, or stomach. If this symptom persists, it’s worth discussing with your doctor.

7. Persistent Cough or Hoarseness
A cough that does not go away, especially one that produces blood, or hoarseness that lasts for more than a few weeks, can be signs of lung or throat cancer.

8. Unexplained Bleeding
Any bleeding that occurs without explanation, such as blood in the stool, urine, or coughing up blood, can be a red flag for several cancers, including colorectal and lung cancer.

9. Changes in the Mouth
Sores in the mouth that do not heal, white or red patches inside the mouth, or persistent bleeding in the mouth can indicate oral cancer.
