Fat and Cholesterol leads to Aggressive Breast Cancer, Found in a Mouse Study

Researchers at the Kimmel Cancer Center at Jefferson determined how the American diet that high in fat and cholesterol makes cancer tumors grow and spread faster, in a mouse study.

Philippe G. Frank, Ph.D., Assistant Professor in the Department of Stem Cell Biology and Regenerative Medicine at Thomas Jefferson University found breast cancer tumors use cholesterol as building blocks to grow, making them more aggressive. Read more



Digestion of Green Tea Protects Brain from Toxins that Cause Alzheimer's Disease

In a first study, scientists found digested compounds in the brew protect cells from toxins that cause dementia and Alzheimer's disease as well as slowing cancer growth, that they weren't sure existed after the beverage was consumed and digested.

Scientists from Newcastle University used technology that simulates the human digestive system to find the anti-cancer and brain protective properties of digested green tea. In the lab, the researchers exposed cells to hydrogen peroxide and a protein known as beta-amyloid that plays a role in the development of Alzheimer's disease. (read more)



Men who Exercise Vigorously more Likely to Survive Prostate Cancer

Vigorous exercise is found to lower the chances of dying after prostate cancer by 46 percent.

Exercise lowers the chances of dying from any cause, but in the study, men who performed vigorous exercise following a diagnosis of prostate cancer were found to have the lowest risk of dying from the disease.

The findings, published in the Journal of Clinical Oncology, included 2,705 men diagnosed with prostate cancer who were part of the 18-year Health Professionals Follow-Up Study. In the study, exercise and prostate cancer deaths were compared among men who reported how much time they spent performing physical activity such as walking, running, biking, swimming, sports and working outdoors.
