It is hoped that early testing will improve lifestyle factors in those at risk such as diet and exercise.Screening and selection for primary prevention interventions has traditionally been done through absolute risk using a variety of scores (ex. Framingham or Reynolds risk scores). This stratification has separated people who receive the lifestyle interventions (generally lower and intermediate risk) from the medication (higher risk). The number and variety of risk scores available for use has multiplied, but their efficacy according to a 2016 review was unclear due to lack of external validation or impact analysis. Risk stratification models often lack sensitivity for population groups and do not account for the large number of negative events among the intermediate and low risk groups. As a result, future preventative screening appears to shift toward applying prevention according to randomized trial results of each intervention rather than large-scale risk assessment. Prevention
Up to 90% of cardiovascular disease may be preventable if established risk factors are avoided. Currently practised measures to prevent cardiovascular disease include:

Maintaining a healthy diet, such as the Mediterranean diet, a vegetarian, vegan or another plant-based diet. Replacing saturated fat with healthier choices: Clinical trials show that replacing saturated fat with polyunsaturated vegetable oil reduced CVD by 30%. Prospective observational studies show that in many populations lower intake of saturated fat coupled with higher intake of polyunsaturated and monounsaturated fat is associated with lower rates of CVD. Decrease body fat if overweight or obese.
Similarly, an enlarged right supraclavicular lymph node tends to drain thoracic malignancies such as lung and esophageal cancer, as well as Hodgkins lymphoma. History
Virchows nodes are named after Rudolf Virchow (1821–1902), the German pathologist who first described the nodes and their association with gastric cancer in 1848. The French pathologist Charles Emile Troisier noted in 1889 that other abdominal cancers, too, could spread to the nodes. Additional images
