According to a new big study undertaken by researchers at the American Cancer Society, smoking and older age are the two most important risk factors associated with a relative and absolute five-year likelihood of developing any cancer (ACS).The findings of the research were published in the journal 'Cancer'.The findings also demonstrate that in addition to age and smoking history, clinicians should consider excess body fatness, family history of any cancer, and several other factors that may help patients determine if they may benefit from enhanced cancer screening or prevention interventions."Single cancer type-specific screening recommendations are based on risk factors for that specific type of cancer," said Dr. Alpa Patel, senior vice president, population science at the American Cancer Society and lead author of the study. "Our findings are encouraging as we are working to define subgroups in the general population who could benefit from enhanced cancer screening and prevention."For this study, researchers analyzed two ACS prospective cohort studies, Cancer Prevention Study-II Nutrition Cohort and Cancer Prevention Study-3 to identify the risk factors associated with greater than two-per cent absolute risk of any cancer within five years. The authors studied 429,991 participants in the United States with no prior personal history of cancer and followed for cancer for up to five years.Multivariable Cox proportional hazards models were used to estimate hazard ratios (HR) and 95 per cent confidence intervals for the association. Using these HRs, individualized Coherent Absolute Risk Estimation was used to calculate absolute risks by age.The results showed that 15,226 invasive cancers were diagnosed among participants within five years of enrollment. The multivariable-adjusted relative risk of any cancer was strongest for current smokers compared with never smokers. In men, alcohol intake, family history of cancer, red meat consumption, and physical inactivity were also associated with risk.In women, body mass index (BMI), type 2 diabetes, hysterectomy, parity, family history of cancer, hypertension, tubal ligation, and physical inactivity were associated with cancer risk.Absolute five-year risk exceeded two per cent among nearly all persons greater than 50 years old and among some persons less than 50 years old including current or former smokers (less than 30 years since quitting) and long-term nonsmokers with a BMI greater than 25 or a first-degree family history of cancer. The absolute five-year risk was as high as 29 per cent in men and 25 per cent in women."As we consider the possibility that future tests may be able to identify several types of cancer, we need to begin understanding who is most at risk for developing any type of cancer," said Patel. "These types of data are not widely available, but necessary to inform future screening options, such as blood-based multi-cancer early detection tests that could help save lives."( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
