Many people mistakenly believe that a single examination can detect all possible cancers. However, this is a dangerous misconception that has nothing to do with reality — such a myth was debunked by an oncologist in an interview, reports infohub.kz.
According to the specialist, there is currently no universal test capable of diagnosing all types of cancer. Each type of oncology requires its own approach: some use instrumental methods (mammography, colonoscopy, CT scans), others require laboratory tests (e.g., PSA for prostate cancer), and some forms of the disease have no effective screening programs at all.
The oncologist emphasized that trying to test 'for everything at once' is not only useless but potentially harmful. Mass prescription of unnecessary tests can lead to false positives, additional invasive procedures, and psychological stress for the patient. Moreover, healthcare resources should be allocated rationally — screening is justified only for cancers where its effectiveness has been proven.
The doctor urged people not to trust dubious offers of 'comprehensive cancer diagnostics' in commercial clinics, but instead to undergo regular preventive check-ups according to recommendations for their age and risk group. Only in this way can the disease be detected in time and the chances of successful treatment increased.
