Prostate cancer is a malignancy of one of the major male sex glands, in which cells of the prostate become abnormal and start to grow uncontrollably, forming tumors.
Study confirms link between omega-3 fatty acids and increased prostate cancer risk — Consumption of fatty fish and fish-oil supplements linked to 71 percent higher risk – A second large, prospective study by scientists at Fred Hutchinson Cancer Research Center has confirmed the link between high blood concentrations of omega-3 fatty acids and an increased risk of prostate cancer.
Observation is safe, cost-saving in low-risk prostate cancer — Study suggests low-risk patients can forego immediate treatment – Many men with low-risk, localized prostate cancers can safely choose active surveillance or “watchful waiting” instead of undergoing immediate treatment and have better quality of life while reducing health care costs, according to a study by researchers at Dana-Farber Cancer Institute and Massachusetts General Hospital.
New prostate cancer test improves risk assessment — Tool tested by UC San Francisco helps identify those best suited for active surveillance – A new genomic test for prostate cancer can help predict whether men are more likely to harbor an aggressive form of the disease, according to a new UC San Francisco study. The test, which improves risk assessment when patients are first diagnosed, can also aid in determining which men are suitable for active surveillance – a way of managing the disease without direct treatment.
Early-onset baldness in African-American men may be linked to prostate cancer – Baldness was associated with an increased risk of prostate cancer among African-American men, and risk for advanced prostate cancer increased with younger age and type of baldness, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Scientists develop a blood test that detects aggressive prostate cancers — Spanish and British scientists design a precision blood test that uses blood cells to detect aggressive prostate cancer – Scientists have developed a test that studies genetic patterns in blood cells to detect advanced?stage prostate cancer. The study shows that gene patterns in blood cells act as a barcode and could be used together with the current PSA test to select those patients with the worst prognosis in need of immediate treatment.
New Test May Help Predict Prostate Cancer – Karim Kader, MD, PhD, associate clinical professor at the UC San Diego School of Medicine, together with a team of researchers from Wake Forest University School of Medicine, have developed a genetic test to predict a man?s risk for prostate cancer.
Gold nanoparticles could treat prostate cancer with fewer side effects than chemotherapy — In new study published in PNAS, scientists found that nanoparticles, produced from chemicals in tea, reduced tumors by 80 percent – Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs and drastically affect bodily functions. Now, University of Missouri scientists have found a more efficient way of targeting prostate tumors by using gold nanoparticles and a compound found in tea leaves.
Psychological Science explains uproar over prostate-cancer screenings – The uproar that began last year when the U.S. Preventive Services Task Force stated that doctors should no longer offer regular prostate-cancer tests to healthy men continued this week when the task force released their final report.
Testosterone supplements may help heart failure patients – Testosterone supplements helped heart failure patients breathe better and exercise more. This new research analyzed four randomized clinical trials of patients with moderate to severe chronic heart failure. Patients were given commercial testosterone supplements by injection, patch or gel.
Intensity Modulated Radiation Therapy optimal for localized prostate cancer – A treatment for localized prostate cancer known as Intensity Modulated Radiation Therapy (IMRT) is better than conventional conformal radiation therapy (CRT) for reducing certain side effects and preventing cancer recurrence.
Breast cancer risk gene discovery fast tracked by new technology – massively parallel sequencing – A new technology is developed to fast track the discovery of a breast cancer risk gene and could assist in the discovery of other cancer genes. Now, breast cancer risk gene can be discovered using the latest genetic sequencing technology.
Single antibody shrinks variety of human tumors transplanted into mice, Stanford study shows – Human tumors transplanted into laboratory mice disappeared or shrank when scientists treated the animals with a single antibody. This antibody works by masking a protein flag on cancer cells that protects them from macrophages and other cells in the immune system.
