Introduction
Cancer is one of the leading causes of death worldwide, and early detection is key to successful treatment. While some types of cancer develop silently, the body often gives warning signs that something is wrong. Unfortunately, many people ignore these symptoms, assuming they are caused by minor health issues. Recognizing these early warning signs can lead to timely medical intervention and improve survival rates.
Here are 10 warning signs of cancer that should never be ignored.
1. Unexplained Weight Loss
What It Means
Losing weight without dieting or exercise can be a major red flag. If you lose 10 pounds or more without trying, it could indicate an underlying medical condition, including cancer.
Possible Causes
- Cancers of the stomach, pancreas, lungs, or esophagus can affect appetite and metabolism.
- Certain tumors release chemicals that cause the body to burn calories faster.
When to Seek Help
If you experience unintentional weight loss of 5% or more of your body weight in a short period, consult a doctor.
2. Persistent Fatigue
What It Means
Feeling constantly tired, even after rest, may indicate cancer. Cancer-related fatigue is more severe than normal tiredness and does not improve with sleep.
Possible Causes
- Leukemia and lymphoma affect blood cell production, leading to extreme fatigue.
- Colon or stomach cancer can cause blood loss, leading to anemia and weakness.
- Cancer-related inflammation interferes with the body’s energy supply.
When to Seek Help
If fatigue is persistent, extreme, and unexplained, it’s important to see a doctor.
