People with cardiovascular-kidney-metabolic syndrome have as much as a 30% higher risk of developing cancer, according to a new study that researchers say could reshape how doctors screen and manage patients with the condition.
The study found that cancer risk scales with the severity of CKM syndrome, a condition that involves overlapping problems with heart function, kidney health, and metabolic processes such as blood sugar regulation and obesity. At stage 1, the increased cancer risk is about 3%. By stage 4, the most severe classification, that risk climbs to 30%. Researchers say the findings matter in part because CKM syndrome is extraordinarily common. It is estimated that 90% of adults in the United States have at least some components of it.
"These findings suggest that CKM staging may help identify individuals at increased cancer risk, supporting a more holistic approach to risk stratification beyond cardiovascular outcomes," the researchers wrote.
The study was observational, which means researchers were able to identify an association between CKM syndrome and cancer risk but could not prove one causes the other. Still, the authors argued the findings have broad clinical implications. They called for cancer prevention to be built into the standard treatment framework for CKM patients, writing that the work extends "the clinical relevance of the CKM framework beyond cardiovascular and kidney outcomes, underscoring the need for integrated risk assessment and prevention in multimorbid individuals."
Outside experts contacted by Healthline largely agreed the findings deserve attention. Michael McConnell, a clinical professor of cardiovascular medicine at Stanford Medicine, pointed to well-documented overlap between the two disease categories. "The study does not provide a mechanism, but the existing science has shown that there is a large overlap in risk factors for [cardiovascular disease] and cancer," McConnell said.
Christopher Berg, a non-interventional cardiologist specializing in cardio-oncology at MemorialCare Heart and Vascular Institute at Orange Coast Medical Center in Fountain Valley, California, said the research adds to a growing body of work linking heart disease, metabolic dysfunction, and chronic kidney disease with elevated cancer risk. But he also cautioned that the study stops short of giving doctors much to act on. "This study may help identify at-risk patients but is less helpful in pointing toward a solution beyond a general recommendation to work toward better health to reduce the risk of future illness," Berg told Healthline.
Berg's practical guidance was straightforward: focus on reducing cardiovascular risk first. He noted that the lifestyle measures proven to protect the heart, maintaining a healthy diet, exercising regularly, avoiding alcohol and tobacco, are largely the same ones associated with lower cancer risk.
The study's authors echoed that view, framing integrated care as the logical next step. For physicians treating patients already managing heart, kidney, or metabolic conditions, the research suggests cancer screening conversations may need to start earlier and happen more often.
The findings were published in a peer-reviewed journal, though the full publication details were not available in the summary released ahead of print. Researchers said further work is needed to identify the biological mechanisms that might connect CKM syndrome to cancer development.
