Common Symptoms That Lead to Cancer Diagnosis
1. Unexplained Weight Loss
A significant, unintentional loss of weight—typically more than 10 pounds—can be an early sign of cancers such as those of the esophagus, stomach, pancreas, or lungs. This symptom occurs because cancer can alter metabolism and cause the body to burn more energy, or reduce appetite due to tumor effects[1][2][3][4][5].
2. Persistent Fatigue
Unlike ordinary tiredness, cancer-related fatigue is profound and does not improve with rest. It may be caused by the cancer itself or as a side effect of treatment. Fatigue can affect daily functioning and is one of the most common and disruptive symptoms[1][6][3][4][5].
3. Unusual Lumps or Swelling
The discovery of a new lump, bump, or swelling—especially if it is hard, painless, and steadily increasing in size—can be a sign of cancer. Such lumps may appear in the breast, testicle, neck, or other soft tissues and should be evaluated promptly[7][8][3][4][5].
4. Skin Changes
Changes in the skin, such as jaundice (yellowing of the skin or eyes), new or changing moles, or sores that do not heal, can indicate skin cancer or other malignancies. Notable changes include moles that become asymmetrical, change color, or grow in size[1][7][3][5].
5. Persistent Pain
Pain that does not go away and cannot be explained by other causes may be related to cancer, especially if it is persistent or worsening over time[1][7][3][4][5].
6. Changes in Bowel or Bladder Habits
Unexplained changes such as constipation, diarrhea, blood in the stool or urine, or changes in urinary frequency or urgency can be early signs of cancers affecting the digestive or urinary systems[7][3][4][5].
7. Other Notable Symptoms
- Persistent cough, hoarseness, or shortness of breath
- Difficulty swallowing or persistent indigestion
- Unexplained bleeding or bruising
- Mouth or tongue sores that do not heal
- Ongoing bloating or loss of appetite
