There's a lot of interest, but still a lot of unanswered questions about the the novel coronavirus disease, called COVID-19. For now, we know it spreads quickly, and has a higher death rate than our common flu, and that our efforts to prevent it are similar: wash your hands frequently and thoroughly, keep a safe distance (6 feet) from people.
Published Epidemiologic Reviews, researchers followed a total of 100 studies, involving thousands of individual patients whose exercise behavior was assessed following the diagnosis of any type of cancer.
There are 2 major categories of health concerns for cancer patients and survivors: 1) concern regarding cancer recurrence and mortality, and 2) the persistent adverse effects of cancer treatment.
Pancreatic cancer initially has very few symptoms, so it often goes undiagnosed. That's unfortunate, as approximately 1.6 percent of adults in the US will be diagnosed with pancreatic cancer at some point. The 5-year survival rate for patients treated for pancreatic cancer is only 8.5%.
That's all pretty daunting. Researchers are actively seeking better treatment, but it would help if they could detect this cancer at an earlier stage.
Scientists at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, have been looking into better ways to treat leukemia.
Specifically, their concern for leukemia patients is that drugs will restrict the progression of their disease, but not completely eliminate it. Therefore, leukemia patients are constantly taking drugs to manage their disease, often with unpleasant side effects, and comes with a risk of resistance and then failure to respond.
Scientists at the Salk Institute made an interesting discovery (published in the journal Nature, on January 23, 2019), when studying how telomeres relate to cancer. A cellular process called autophagy (the body's way of cleaning out damaged cells, in order to regenerate newer, healthier cells), can actually promote cell death, which would prevent damaged cells from becoming cancerous.
There are many checkpoints in the body that try to prevent cells from dividing out of control (become cancerous), but this was not expected.
