Beyond Pain: Why Early Cancer Screening is Crucial for Silent Cancers

• Many cancers, including ovarian, pancreatic, liver, and colon cancer, often develop without early or clear symptoms, remaining unnoticed until advanced stages.
• Pain typically occurs when a tumor is large enough to press on nerves, block organs, or cause inflammation; smaller, early-stage tumors usually do not cause discomfort.
• Waiting for pain before seeking medical evaluation can lead to delayed diagnosis, highlighting the limitations of symptom-based detection.
• Persistent but mild signs like constant tiredness, unexplained weight loss, or changes in bowel habits, if prolonged, warrant medical attention.
• Early detection is strengthened by wider access to structured screening programs, risk-based surveillance, and integrating preventive check-ups into routine care.
