Recent research illustrates just how important these CT scans are for diagnosing cancer. They expose deep concerns, reflected in the potential harm associated with their use. These expensive and generally unproven advanced imaging techniques have been lifesaving in many cases, experts warn that the potential harms are usually downplayed or overlooked.
CT scans are clinically indicated in many circumstances, especially for patients with known or suspected symptoms or signs of malignancy. These tools are essential for assessing patients. They are particularly important for lung cancer screening, where the evidence is strongest among those at high risk, such as people with a long history of chronic smoking. Doctors stress that lung cancer screening should be focused on patients at a high risk. Such risk frequently results from decades of habitual smoking. Reviewing staging CT scans within this patient population reduces the stage at which they are diagnosed. That increased benefit in turn translates to better results for them. Benefit far outweighs the risk.
The dividends of CT scans go far beyond identifying cancer. They help avoid invasive surgeries, unnecessary hospital admissions, and the length of hospital stays. According to the American College of Radiology (ACR), medical imaging exams, including CT scans, are key to finding and treating cancers that reduce cancer death rates. These tests are unequivocally linked to decreased hospital mortality and greater long-term survival. These benefits are noteworthy. They highlight the need to weigh the benefits against their potential harms.
The Risk Factor in Imaging
A joint study by ACR and NCHS shows that CT scans save lives. On the flip side, they potentially increase people’s lifetime cancer risk by a small amount. This unexpected result has led to apprehension about the long-term effects of radiation exposure from these scans. Rebecca Smith-Bindman, MD drives home this duality by saying, “CT can save lives, but we frequently focus on the potential harms.”
As outlined in the research, healthcare providers should be determining the amount of radiation dosage for each exam. This practice is the very foundation of patient safety and quality care. This method maximizes the benefits while minimizing the risks associated with imaging. While significantly reducing patients’ radiation exposure, it preserves the robust diagnostic advantages of CT scans.
Patient Advocacy and Informed Decision Making
Given these results, specialists urge the involvement of patients when introducing and explaining a diagnostic test. Healthcare providers have long argued that patients need to be active and educated consumers of all types of diagnostic testing—CT scans included. As these experts made clear, self-advocacy is a key ingredient for patients too. They should be uniquely proactive in engaging and communicating with their physicians with respect to ALL diagnostic testing – CT scans, lab tests, etc.
By learning more about the risks posed by CT scans, patients can make smart decisions about their health care alternatives. It is extremely important that all patients and all clinicians understand and evaluate risks compared to benefits when making a decision about CT imaging.
The Broader Impact on Cancer Outcomes
As medical imaging technology advances, CT scans will play an increasingly crucial role in ensuring positive cancer prevention and treatment outcomes. They are critical in the diagnosis of cancers including breast and lung cancer. In the process, they cut mortality rates linked to such diseases.
In females, breast cancer remains the second overall most common cancer anticipated worldwide. For kids, thyroid, lung and breast cancers are the most commonly expected cancers. Ongoing access to CT scans remains crucial to help screen for and follow up on many of these worthwhile conditions.
