Millions of men with heart disease face a higher risk of developing and dying from cancer than women with similar heart conditions, according to a long-term UK study. This gender difference aligns with broader research indicating overlapping risk factors and outcomes between cancer and cardiovascular disease, as seen in related studies published in large cohorts and meta-analyses (1, 12).
- Multiple studies confirm that both cancer and cardiovascular disease share common risk factors—such as smoking, obesity, and alcohol use—and that men generally have higher risks of both conditions and related mortality (1, 12, 15).
- Research has repeatedly shown that men with existing cardiovascular disease or cancer have worse long-term outcomes, including higher mortality from both conditions, compared to women (1, 12, 15).
- Findings from the UK study are consistent with international evidence showing increased cancer incidence and mortality in people with cardiovascular disease, with sex differences observed in both disease risks and outcomes (1, 12, 15).
Study Overview and Key Findings
This new observational study addresses an important knowledge gap about how cardiovascular disease influences cancer risk differently in men and women. With cancer and cardiovascular disease among the leading causes of death globally, understanding their interplay—especially any sex-based differences—is crucial for improving prevention and care. The study tracked health outcomes in over 22,000 Britons for up to 25 years, providing rare longitudinal data across multiple cancer types and cardiovascular conditions. Notably, the research also highlights the need for integrated screening and prevention strategies, particularly for men with heart disease.

Literature Review: Related Studies
To situate the new findings within the broader scientific landscape, we searched the Consensus research paper database (over 200 million papers) using targeted queries. The following search queries were used:
- heart disease cancer risk men
- cardiovascular disease cancer mortality comparison
- gender differences cancer risk heart disease
Below, we summarize key themes and findings from the most relevant studies.
| Topic | Key Findings |
|---|---|
| Are men with heart disease at greater risk for cancer and mortality than women? | - Men with heart disease or cancer have higher risks of fatal outcomes from both conditions compared to women, with shared risk factors like smoking and obesity contributing to this disparity (1, 12, 15). - The risk of both cancer and CVD mortality is higher in unmarried or divorced men (1, 12). |
| How do cancer and heart disease interact in terms of risk and mortality? | - Cancer patients have an elevated risk of dying from cardiovascular disease, and vice versa; the risks are highest within the first years after diagnosis but remain elevated long-term (1, 6, 9, 10). - Shared risk factors and treatment-related effects may explain this overlap (1, 6, 8, 9). |
| What is known about sex differences in cardiovascular and cancer outcomes? | - Sex differences are observed: women with diabetes have higher CVD risk than men, but men have higher cancer/CVD mortality overall, and marital status modifies these risks (11, 12, 13, 14). - Type-D (distressed) personality and heart rate are additional risk factors in men with CVD (4, 5). |
| What are the drivers of the gender gap in life expectancy and disease outcomes? | - Neoplasms (cancers), heart diseases, and external causes are the main contributors to the gender gap in life expectancy, with men’s survival improving over time due to advances in diagnosis and treatment (15). |
Are men with heart disease at greater risk for cancer and mortality than women?
Numerous cohort studies and meta-analyses agree that men with heart disease experience higher cancer incidence and mortality compared to women. This is consistent with the UK study’s finding of a 17.3% lifetime cancer risk in men with CVD, compared to 12.8% in women. These differences are attributed to both biological and behavioral factors, such as higher rates of smoking, alcohol consumption, and obesity in men. Social determinants like marital status also play a role, with unmarried or divorced men facing particularly high risks.
- The risk of fatal heart disease is highest among older, male, and unmarried cancer patients (1).
- Being unmarried or divorced/separated is associated with higher cancer and CVD mortality in men than in women (12).
- Shared behavioral risk factors (e.g., smoking, obesity, alcohol use) likely drive much of the excess risk in men (1, 12).
- Improvements in survival and access to treatment have narrowed, but not eliminated, the gender gap (15).
How do cancer and heart disease interact in terms of risk and mortality?
Large-scale studies confirm that cancer patients are at heightened risk of cardiovascular disease, and vice versa. This bi-directional relationship is linked to overlapping risk factors and, in some cases, to treatment-related toxicity. The highest risks often occur in the years immediately following diagnosis but persist over time. The UK study’s observation that men with CVD face higher risks of gastric, esophageal, and lung cancer is mirrored by findings from other cohorts.
- Cancer survivors have an increased risk of premature CVD mortality, which varies by cancer type (9).
- The risk of cardiovascular death in cancer patients is highest in the first year after diagnosis but remains elevated compared to the general population (6, 10).
- A new cancer diagnosis increases the risk of cardiovascular death and nonfatal CVD events, regardless of cancer site (8).
- Shared risk factors and the cardiotoxic effects of some cancer treatments contribute to this interaction (1, 6, 8, 9).
What is known about sex differences in cardiovascular and cancer outcomes?
Sex-based differences in disease outcomes are well-documented but complex. For example, women with diabetes have a higher relative risk of coronary heart disease mortality than men, yet overall, men have higher combined cancer and CVD mortality. Personality traits, such as Type-D personality, and physiological markers like elevated heart rate, also appear to raise cancer risk among men with CVD.
- Women with diabetes have a higher excess risk of CVD mortality than men with diabetes (11).
- Men, especially those divorced or unmarried, remain at higher risk for cancer and CVD mortality (12).
- Type-D personality is identified as a strong prognostic factor for cancer development in men with heart disease (4).
- Higher resting and exercise heart rates predict increased cancer mortality in healthy men (5).
What are the drivers of the gender gap in life expectancy and disease outcomes?
Longitudinal analyses reveal that cancers, heart diseases, and external causes are the primary contributors to the sex gap in life expectancy. Over recent decades, men’s survival advantages have improved due to better diagnosis, treatment, and potentially behavioral change, but men still lag behind women overall.
- Neoplasm-related and heart disease-related mortality are the main contributors to the sex gap in life expectancy (15).
- Survival improvements for men are linked to advances in diagnosis and treatment, especially at older ages (15).
- The narrowing of the survival gap is partly due to men’s risk factors being better managed or reduced over time (15).
Future Research Questions
While the new UK study advances understanding of sex differences in cancer risk among people with cardiovascular disease, several questions remain. Further research is needed to clarify biological mechanisms, intervention strategies, and the impact of social determinants on these gender disparities.
| Research Question | Relevance |
|---|---|
| What biological mechanisms explain the higher cancer risk in men with cardiovascular disease? | Understanding the underlying pathways could inform targeted prevention and treatment. Current evidence points to behavioral factors, but biological differences remain underexplored (1, 12). |
| How can integrated screening and prevention programs reduce cancer and CVD risk in high-risk men? | Combined strategies may improve early detection and reduce mortality. There is limited evidence on the effectiveness of such integrated care, especially for men (8, 10). |
| Are psychosocial factors like personality and marital status modifiable risk factors for cancer and CVD mortality? | Studies indicate that social and psychological factors (e.g., Type-D personality, being unmarried) are linked to higher mortality, especially in men, but it is unclear if interventions can mitigate this risk (4, 12). |
| What role do cancer treatments play in long-term cardiovascular and cancer risk differences by sex? | Some therapies have sex-specific effects on the heart and cancer risk, but the mechanisms are not fully understood. More research is needed to optimize treatment and survivorship care (14). |
| How do lifestyle changes impact the co-occurrence of cancer and CVD in men versus women? | Behavioral risk factors are major contributors to both diseases. Understanding the impact of interventions by sex could guide public health policies (1, 15). |
