Among 238 Spanish colorectal cancer patients studied at diagnosis, only 10 individuals (4.3%) met all seven components of ideal cardiovascular health as defined by the American Heart Association's Life's Simple 7 framework. While 89.5% were non-smokers, obesity emerged as the most concerning factor, with only 39.1% maintaining a BMI under 25. Hypertension affected 62% of patients, highlighting the cardiovascular burden in this population. This finding reveals a critical missed opportunity in cancer care. Since cardiovascular disease represents the leading cause of death among colorectal cancer survivors—not cancer recurrence—optimizing heart health should be integral to oncology treatment from diagnosis forward. The timing is particularly significant because a cancer diagnosis creates a "teachable moment" when patients are most motivated to adopt healthier behaviors. The overlap in risk factors between colorectal cancer and cardiovascular disease suggests that interventions targeting diet, weight management, and blood pressure control could simultaneously improve both cancer outcomes and long-term survival. This represents a paradigm shift toward integrated cardio-oncology care that addresses the whole patient, not just the tumor.
