It can progress without showing any symptoms: Common misconceptions about cancer screening

Radiology specialist Prof. Dr. Ercan Karaarslan warned that some tumors can progress silently without causing any symptoms, making it risky to wait for complaints before seeking screening. He emphasized that early diagnosis depends on age-appropriate and risk-tailored screening methods rather than symptom-driven testing. The comments highlight a common misconception that the absence of symptoms means the absence of disease. The takeaway for patients and clinicians is to follow recommended screening schedules based on individual risk factors.
