Introduction to Cancer Symptoms
Cancer symptoms can vary widely depending on the type and stage of the disease. Recognizing these symptoms early can significantly improve outcomes. This article synthesizes findings from multiple studies to present 20 common signs of cancer.
Common Cancer Symptoms
1. Unusual Bleeding or Discharge
Unusual bleeding or discharge is a significant warning sign of cancer. This can include blood in the urine, stool, or unexpected vaginal bleeding.
2. Lumps or Thickening
The presence of a lump or thickening in the breast or other parts of the body can be an early indicator of cancer. This symptom is often associated with breast cancer but can occur in other cancers as well.
3. Sores That Do Not Heal
Persistent sores that do not heal, especially in the mouth or on the skin, can be a sign of cancer. This is particularly relevant for skin and oral cancers.
4. Changes in Bowel or Bladder Habits
Changes in bowel or bladder habits, such as persistent diarrhea, constipation, or changes in urine frequency, can indicate cancers of the colon, bladder, or prostate.

Difficulty swallowing or persistent indigestion can be signs of esophageal or stomach cancer. These symptoms should not be ignored, especially if they persist.
7. Changes in Warts or Moles
Changes in the size, color, or shape of warts or moles can indicate skin cancer, particularly melanoma. Regular skin checks are essential for early detection.
8. Fatigue
Fatigue is one of the most common symptoms experienced by cancer patients. It can be severe and persistent, significantly affecting quality of life .
9. Pain
Pain, especially if it is persistent and unexplained, can be a symptom of various cancers. It is often associated with advanced stages but can occur early in some cases .
10. Weight Loss
Unintentional weight loss is a common symptom of cancer. It can occur due to the body's increased energy needs or loss of appetite .
11. Anorexia
Anorexia, or loss of appetite, is frequently reported by cancer patients and can lead to significant weight loss and malnutrition .
12. Weakness

13. Anxiety and Depression
Cancer patients often experience anxiety and depression, which can significantly impact their mental health and overall well-being .
