Introduction
Cancer is a deadly disease that often develops silently, with symptoms only appearing at an advanced stage. However, the body can show warning signs that, if recognized early, can lead to early detection and better treatment outcomes. While these symptoms do not always indicate cancer, persistent and unexplained changes in the body should never be ignored.
Here are five early signs of cancer growth that require medical attention.
1. Unexplained weight loss
Sudden, unintentional weight loss of 5 kg or more without any changes in diet or exercise can be an early sign of cancer. This occurs because cancer cells alter the body’s metabolism, causing the body to burn more energy than usual.
Possible cancers linked to unexplained weight loss:
- Cancer of the stomach, pancreas or liver (affecting digestion and metabolism)
- Lung or esophageal cancer (interfering with swallowing and appetite)
- Blood cancers (leukemia, lymphoma) (affecting metabolism and immune function)
If you experience persistent weight loss for no apparent reason, consult a doctor for evaluation.
2. Persistent fatigue and weakness
