Among cancers that affect men and women, colorectal cancer is the second leading cause of cancer deaths in the U.S., according to the Centers for Disease Control and Prevention. Most cases of colorectal cancer begin as small, noncancerous (benign) clumps of cells called polyps. Over time, some polyps become colon cancer. Because these polyps may be small and produce few, if any, symptoms, health care providers recommend regular screening tests to prevent colon cancer. These screenings identify and remove polyps before they become cancerous. March is Colorectal Cancer Awareness month, a time to educate the public about the importance of colorectal cancer screening.
“These results are exciting, as they suggest that people may potentially prevent brain shrinking and the effects of aging on the brain simply by becoming more active,” said study author Yian Gu, Ph.D., of Columbia University in New York and a member of the American Academy of Neurology.
Habitual fish oil supplementation is associated with a 13% lower risk of all cause mortality, a 16% lower risk of CVD mortality, and a 7% lower risk of CVD events among the general population
Rocket scientist-turned-immunology expert Mark Kendall talks about his Nanopatch, which could revolutionise vaccinations and eradicate some diseases.
Seasonal variation in blood pressure has been known for 40 years, but, to our knowledge, for the first time we show here that this occurs independently of temperature. The reduction in blood pressure is more marked with a rise in UVB than UVA, and in whites than black people. Dermatological concerns about the skin cancer inducing effects of UV radiation need to be balanced against the observed blood pressure lowering effects of sunlight, particularly given the greatly higher burden of disease caused by hypertension.
Sunlight exposure appears to lower blood pressure; insufficient exposure to natural ultraviolet radiation and/or active avoidance of sunlight may be new risk factors for hypertension.
We found no association between egg consumption and risk of cardiovascular disease in three large US cohorts. Results from the updated meta-analysis lend further support to the overall lack of an association between moderate egg consumption (up to one egg per day) and cardiovascular disease risk. 
Eggs are a major source of dietary cholesterol, but they are also an affordable source of high quality protein, iron, unsaturated fatty acids, phospholipids, and carotenoids.
What happens when you catch coronavirus? The Telegraph’s Global Health Security Editor Paul Nuki explains all the ways in which you could become infected with COVID-19 and how your body reacts to this virus.
“The opioid epidemic has added fuel to the HCV fire, substantially increasing transmission,” said Owens. “HCV is now an enormous public health problem, affecting a much broader age range of people than before. Fortunately, we have the tools to identify people and treatment is now successful in the vast majority of patients, so screening can prevent the mortality and morbidity from HCV.”
