How Do You Know If You Have Cancer?10 Early Warning Signs You Shouldn’t Ignore
Why Should You Pay Attention?
One in three men and one in four women will be diagnosed with cancer in their lifetime. Many types of cancer can develop silently over years, and by the time symptoms appear, the disease may already be in an advanced stage. Recognizing early warning signs and seeking medical advice promptly can be life-changing.
Who Is at Higher Risk of Cancer?
You may be at higher risk of developing cancer if you fall into one or more of the following categories:
- Chronic illness: Chronic hepatitis, gastric ulcers, inflammatory bowel diseases (IBD), etc.
- Unhealthy lifestyle habits: Smoking, excessive alcohol consumption, betel nut chewing, staying up late, sedentary lifestyle, or lack of exercise
- Family history of cancer: Especially among immediate family members
- Environmental exposure: Long-term exposure to air pollution, toxic chemicals, or ultraviolet (UV) radiation
If you fall into any of these groups, regular health screening is highly recommended.
10 Common Cancer Warning Signs
If any of the following symptoms persist for more than two weeks, consult a healthcare professional for further evaluation:
- Painless lumps: May indicate breast cancer or lymphoma
- Persistent unexplained fever: Can be a sign of leukemia or lymphoma
- Non-healing mouth ulcers: Could be linked to oral cancer
- Hoarseness or chronic cough: Often associated with throat or lung cancer
- Difficulty swallowing: May point to esophageal cancer
- Unexplained bleeding: Such as blood in urine or stool—possible sign of bladder or colorectal cancer
- Rapid, unintentional weight loss: Often seen in pancreatic or gastrointestinal cancers
- Persistent bone or joint pain: May signal bone cancer or metastatic spread
- Chronic headaches or vision changes: Could be related to a brain tumor
- Changes in moles or skin lesions: Irregular size, color, or borders may indicate skin cancer
The “Two-Week Rule”
If any unexplained symptom lasts more than two weeks, seek medical evaluation. Diagnostic tools may include blood tests, imaging (e.g., ultrasound, X-ray, MRI), endoscopy, or biopsy to determine the cause and initiate timely management.
Final Thoughts: You Are the First Line of Defense
Cancer rarely strikes without warning. The body often sends out signals—what matters is whether we pay attention.
Early detection begins with awareness. Regular checkups and listening to your body are key steps in prevention. Don’t dismiss persistent symptoms or hope they’ll go away on their own.
Because:
“If you detect it early, you can act early—and your doctor can help you better.”
