Angiotensin-converting enzyme inhibitors (ACEIs) are commonly prescribed to manage high blood pressure and various heart conditions. These drugs are known to have life-saving benefits, but recent studies have raised concerns about a potential link between prolonged ACEI use and an increased risk of developing lung cancer. This article reviews existing research on ACEIs and lung cancer, while also addressing how to care for older adults with advanced lung cancer—a critical issue in managing complex health conditions.
Angiotensin-Converting Enzyme Inhibitors (ACEIs)
A study found that taking ACEIs, a type of blood pressure medication, was associated with a 14% increased risk of lung cancer. The risk increased with the length of time the drug was taken, with a 31% increased risk for those who took the drug for more than 10 years.
ACEIs work by relaxing blood vessels, easing the workload on the heart, and are commonly prescribed for hypertension, heart failure, and other cardiovascular issues. While they are highly effective, some researchers suggest that the increased lung cancer risk could be related to the accumulation of peptides like bradykinin and substance P, which might promote cell growth in lung tissue. Although this mechanism is plausible, further studies are needed to definitively confirm the connection.
Lung Cancer and ACEI Use
Lung cancer is a leading cause of cancer-related deaths worldwide. It is a complex disease influenced by factors such as smoking, genetic predispositions, and environmental exposures. The potential association between ACEIs and lung cancer requires careful consideration, particularly given the fact that ACEIs are often prescribed to older individuals who already have a higher baseline risk for lung cancer due to age and pre-existing health conditions.
The relationship between ACEIs and lung cancer remains inconclusive. Most studies examining this risk are observational, meaning they identify correlations but cannot establish direct causality. Variables such as smoking history, existing lung diseases, and other environmental factors complicate the interpretation of these findings.
Caring for Seniors with Advanced Lung Cancer
The challenge of caring for an older population with advanced lung cancer is multifaceted. For elderly patients, the complexities of managing both the cancer and the effects of chronic medications like ACEIs require a nuanced approach. Older adults often have multiple comorbidities and are more likely to experience adverse effects from medications, which makes ongoing medical supervision essential.
Healthcare providers must be especially cautious when prescribing treatments to this vulnerable group. The decision to continue ACEIs in patients diagnosed with lung cancer, or to switch to alternative therapies, should involve a comprehensive evaluation of the patient’s overall health status, cancer progression, and potential drug interactions. For many older adults with advanced lung cancer, the goal of care may shift to palliative care—focusing on symptom management and quality of life rather than aggressive treatments.
Comparing ACEIs to Other Blood Pressure Medications
To understand the risks of ACEIs more clearly, comparisons have been made with other antihypertensive medications, such as angiotensin receptor blockers (ARBs). Unlike ACEIs, ARBs do not affect bradykinin levels and have not been associated with an increased lung cancer risk.
However, ARBs may not be as effective for certain individuals or conditions. Deciding to switch medications based solely on concerns about lung cancer risk may not be advisable without consulting a healthcare provider.
Future Directions in Research
Given the important public health implications of a potential ACEI-lung cancer link, further research is needed to clarify the relationship. Randomized controlled trials (RCTs) could provide more concrete answers, but logistical and ethical concerns may limit their feasibility.
In the meantime, larger, long-term studies may offer a clearer understanding of the risks. Additionally, advancements in pharmacogenomics could lead to more personalized medicine, where treatment options are tailored to a patient’s genetic makeup, reducing adverse effects while preserving therapeutic benefits.

Although the evidence linking ACE inhibitors to lung cancer remains inconclusive, ongoing studies continue to shed light on this complex issue. For now, the proven benefits of ACEIs in managing cardiovascular health often outweigh the potential, unconfirmed risks.
Patients who are concerned about lung cancer should avoid undue panic and seek guidance from their healthcare providers. By engaging in informed, personalized care, patients can make the best decisions for their health in the context of ongoing research. As science evolves, so too will our understanding of the complex relationships between medications and long-term health outcomes.
