Cancer is a disease that can affect any part of the body, and early detection is crucial for successful care. Understanding the common signs and symptoms of cancer can help individuals seek medical attention promptly, leading to early diagnosis and better treatment outcomes. While symptoms vary depending on the type and stage of cancer, there are general warning signs that should not be ignored.

Common Signs and Symptoms of Cancer

1. Unexplained Weight Loss
   Significant and unintended weight loss of 5 kg (10 pounds) or more may be an early sign of cancer, particularly cancers of the stomach, pancreas, esophagus, or lungs.
   
   
2. Persistent Fatigue
   Extreme and prolonged tiredness that does not improve with rest could indicate cancers such as leukemia, colon cancer, or stomach cancer. This occurs due to cancer’s impact on red blood cell production or the body’s metabolism.
   
   
3. Unusual Bleeding or Discharge

• Blood in stool or urine may be a sign of colorectal or bladder cancer.
• Unusual vaginal bleeding may indicate cervical or endometrial cancer.
• Coughing up blood could be associated with lung cancer.

4. Lumps or Swelling
   The presence of abnormal lumps or swelling in the breast, testicles, lymph nodes, or other parts of the body should be examined by a doctor. These could be signs of cancers such as breast cancer or lymphoma.
   
   
5. Changes in the Skin

• Darker, yellowish, or reddened skin.
• Persistent sores that do not heal.
• Changes in moles or skin spots (size, shape, or color), which may indicate melanoma.

6. Persistent Cough or Hoarseness
   A long-lasting cough, difficulty swallowing, or persistent hoarseness may be a symptom of lung, throat, or thyroid cancer.
   
   
7. Digestive or Urinary Changes

• Persistent indigestion or difficulty swallowing could be a symptom of esophageal or stomach cancer.
• Changes in bowel habits (diarrhea, constipation, or narrowing of stool) could be linked to colorectal cancer.
• Frequent urination or difficulty urinating may indicate prostate or bladder cancer.

8. Persistent Pain
   Chronic pain that does not have an obvious cause could be related to bone cancer or other forms of cancer that have spread (metastasized).

When to See a Doctor
If you experience any of the above symptoms persistently or if they worsen over time, it is essential to seek medical advice. While these symptoms may not always indicate cancer, early detection and diagnosis can significantly improve treatment options and outcomes.

Conclusion
Recognizing cancer signs and symptoms can lead to early diagnosis and better chances of successful care. It is crucial to pay attention to changes in the body and seek professional medical advice for further evaluation. Regular screenings and a healthy lifestyle can also play a vital role in cancer prevention and early detection.
