Cancer is often only detected in its late stages, but our body silently sends out distress signals beforehand.
Pay attention to any abnormal signs! Today, let’s explore 9 early warning signs that could be related to cancer, helping you to take preventive measures and protect your health before it’s too late.
Sign 1: Prolonged fatigue with no apparent cause
While fatigue is a common occurrence, persistent exhaustion despite adequate rest could be a serious warning from your body. It may indicate a weakened immune system or even the initial stages of cancer. Notably, chronic fatigue is often associated with tumors in the digestive system, so those prone to constipation should be extra vigilant.
Sign 2: Persistent cough that won’t go away
Coughing is a natural reflex to clear bacteria and irritants from the respiratory tract. However, if you’ve been coughing continuously for more than two weeks without signs of improvement despite medication, it’s time to get checked. This could be an early sign of serious conditions such as lung tumors or lung cancer. Regular chest X-rays can help with early detection.

Sign 3: Chronic indigestion and heartburn
Feeling full, indigestion, or heartburn can be more than just irregular eating habits. If these symptoms persist despite medication, it’s likely a warning sign of stomach ulcers or stomach cancer. Don’t ignore it if you start losing your appetite and experiencing unexplained weight loss.
Sign 4: Persistent bloating in women
Women, especially those in their middle ages, who experience frequent bloating and loss of appetite without a clear cause, should consult a doctor. This could be an early sign of ovarian cancer, a disease that progresses silently but can be extremely dangerous if left untreated.
Sign 5: Persistent and intense abdominal pain
Recurring abdominal pain, especially at night, may indicate pancreatic cancer. Those with a history of chronic pancreatitis should be particularly cautious, as pancreatic cancer is one of the most challenging types of cancer to detect and has a poor prognosis if treatment is delayed.
Sign 6: Prolonged mouth ulcers that won’t heal
Mouth ulcers usually heal within a few days to a week. However, if they persist for several weeks without healing, it could be an early warning sign of oral mucosal leukoplakia, a condition that can progress into mouth cancer. Those who smoke or consume alcohol regularly should pay extra attention to this sign.

Sign 7: Blood in stool accompanied by diarrhea
The presence of blood in the stool often raises concerns about hemorrhoids. But if this occurs along with increased bowel movements, loose stools, or changes in stool shape, don’t ignore it. It could be an early sign of colorectal cancer, one of the most common types of cancer today. Those with a history of colon polyps should not skip regular health check-ups.
Sign 8: Persistent fever with no clear cause
Recurrent mild fever may be mistaken for a common cold. However, if the fever persists and doesn’t respond to standard treatment, be vigilant. Certain malignant conditions like leukemia can begin with a low-grade fever. Monitoring body temperature and other accompanying symptoms is crucial for early detection of serious illnesses.
Sign 9: Blood in urine
Finding blood in your urine, even without pain or other symptoms, is a reason for concern. It is a classic sign of bladder cancer, which often progresses silently. Early detection and treatment significantly improve the chances of recovery.
