Cancer often has no obvious signs in its early stages, but experts at John Hopkins University caution that certain symptoms can be early warnings. Ignoring these subtle clues could mean missing an opportunity for early diagnosis, which is crucial for effective treatment. Here are five common symptoms that people tend to overlook but should never be dismissed:
1. Shortness of Breath
While it’s normal to feel winded after physical exertion, such as running or exercising, experiencing shortness of breath during routine activities like climbing stairs or carrying groceries is a red flag. This could indicate an underlying health problem that needs to be checked out.
2. Unexplained Bleeding
Bleeding without an obvious cause should always be investigated. While not all cases are related to cancer, certain types are more concerning. This includes:
- Coughing up blood
- Blood in stool
- Unusual vaginal bleeding
- Blood in urine
- Nipple discharge or bloody spots
Even if these symptoms are caused by less serious conditions, they warrant a medical review.
3. Lumps and Masses
Lumps, especially those that don’t go away or seem different from typical swollen lymph nodes during an illness, should not be ignored. Many lumps are benign, but any that persist or feel unusual should be examined to rule out cancer.
4. Difficulty Swallowing
Struggling to swallow, particularly if food feels like it’s getting stuck in your throat (a condition known as dysphagia), is another symptom that could signal a problem. While it’s not always related to cancer, it can be a sign that warrants further attention if it persists.
5. Bloating
Feeling unusually full after eating small amounts or experiencing bloating that doesn’t go away could indicate an issue with your digestive system, potentially related to cancer. Persistent bloating should be checked by a healthcare provider to ensure it’s not linked to a more serious condition.
6. Changes in Bodily Functions
Sudden, persistent changes in bowel or urinary functions—like unexplained constipation, diarrhea, or difficulty fully emptying the bladder or bowels—should be cause for concern. These changes may not always signal cancer but can indicate other underlying health issues that need to be addressed.
Doctors stress that while these symptoms don’t always point to cancer, ignoring them can be dangerous. Early detection is key to effective treatment, so if you notice any of these symptoms, it’s always safer to consult with a doctor.
