Cancer symptoms can sometimes masquerade as ordinary ailments, causing people to overlook warnings that could save their lives. Experts at Johns Hopkins University urge individuals to be vigilant and not dismiss subtle signs that might signal cancer.
One key symptom is unexplained shortness of breath—not just after exercise but during everyday tasks like climbing stairs or carrying groceries. This could indicate lung or blood-related cancers affecting oxygen delivery.

Unexplained bleeding is another critical sign. While some bleeding may have benign causes, coughing up blood, blood in stool, urine, abnormal vaginal bleeding, or bloody nipple discharge should never be ignored and prompt further investigation.
Lumps or masses that persist or feel unusual warrant medical examination, as some cancers manifest visibly or through changes in bodily tissues.
Difficulty swallowing, known medically as dysphagia, especially if worsening, could point to cancers in the throat, esophagus, or adjacent areas.
Persistent bloating, feeling full after eating little, or changes in bowel and bladder functions, such as constipation, diarrhea, or blood in urine or stool, also require prompt medical evaluation.
Early detection is crucial, and consulting a doctor about any unusual or persistent symptom is an essential step towards timely diagnosis and effective treatment.
