Natural substance studied for future treatment of possibly incurable childhood cancer

In their laboratory experiments Christina Fjæraa Alfredsson and her colleagues have studied how ellagic acid affects the growth and survival of cultivated neuroblastoma cells. An important discovery was that adding ellagic acid resulted in a so-called programmed cell death. …

Researchers develop tool to determine individual risk of prostate cancer overdiagnosis

Now, researchers at Fred Hutchinson Cancer Research Center and the University of Washington have developed a personalized tool that can predict the likelihood of prostate cancer over-diagnosis. They announced their findings this week in the online issue of the Journal of the National Cancer Institute…

Cancer increasing as babyboomers age

"The increase in the number of older adults, the association of cancer with aging, the workforce shortage, and the financial stressors across the health care system and family networks all contribute to a crisis in cancer care that is most pronounced in the older population," wrote three members of the Institute of Medication Committee on Improving the Quality of Cancer Care: Addressing the Challenges of an Aging Population in an editorial published In JAMA, The Journal of the American Medical Association. "Often caregiving falls to a family member who is also aging," noted Mary D. Naylor, PhD, FAAN, RN, the Marian S. Ware Professor in Gerontology and the Director of the NewCourtland Center for Transitions and Health and a member of the committee…

Women prescribed hormone therapy should use caution when taking apigenin supplement

A new study shows that when the supplement apigenin is ingested in a diet at the same concentration as subjects received during IV injections in previous studies — the benefits were reversed leading to a higher incidence of cancerous tumors in subjects receiving progestin. "Typically, hormone replacement therapies improve the lives of menopausal women and achieve very good results," said Salman Hyder, the Zalk Endowed Professor in Tumor Angiogenesis and professor of biomedical sciences in the College of Veterinary Medicine and the Dalton Cardiovascular Research Center. "However, research has proven that in women receiving therapies that involve a combination of the natural component estrogen and the synthetic progestin, a higher incidence of breast cancer tumors can occur." Hyder explains that many women normally have benign lesions in breast tissue. These lesions don’t typically form tumors until they receive the "trigger" that attracts blood vessels to cells essentially feeding the lesions causing them to form and expand — in this case, progestin is the trigger…
