Cancer’s early warnings often mimic commonplace health issues, leading to dangerous delays in diagnosis. Specialists at Johns Hopkins emphasize the importance of recognizing five symptoms that should never be ignored.
Shortness of breath during non-exertive activities might signal cancers affecting respiratory or cardiovascular systems.

Unexplained bleeding—including blood in coughs, stool, urine, or abnormal vaginal bleeding—needs urgent evaluation to rule out malignancies.
Persistent lumps or masses, especially those growing or accompanied by changes in the skin, may be cancerous.
Difficulty swallowing food or sensation of blockage in the throat is a red flag symptom for head, neck, or esophagus cancers.
Unexpected abdominal bloating or notable changes in bowel or urinary patterns, especially when persistent, also merit prompt medical attention.
Ignoring such symptoms risks delayed diagnosis, underscoring the life-saving power of awareness and early medical intervention.
