Using data from surveys conducted in 2000 and 2005, researchers report that nearly half of men in their seventies underwent PSA screening in the past year – almost double the screening rate of men in their early fifties, who are more likely to benefit from early prostate cancer diagnosis and treatment. Further, men aged 85 and older were screened just as often as men in their early fifties. http://phys.org/news220549027.html Medicine & Health Mon, 28 Mar 2011 16:37:16 EST news220549027 A new study has shown that a surgical technique called microdissection testicular sperm extraction (TESE) can effectively locate and extract viable sperm in more than one-third of adult male childhood cancer survivors who were previously considered sterile due to prior chemotherapy treatment. As a result, many of the men were subsequently able to father children with the help of in vitro fertilization. The findings offer a new option for many cancer survivors who want to have children but were thought infertile because of earlier cancer treatment. http://phys.org/news219330071.html Medicine & Health Mon, 14 Mar 2011 15:00:01 EST news219330071 Researchers have found that a novel form of personalized therapy that genetically engineers a patient's own anti-tumor immune cells to fight tumors could treat metastatic melanoma and metastatic synovial cell sarcoma, representing a potentially new therapeutic approach against these and other cancers. http://phys.org/news215714057.html Medicine & Health Mon, 31 Jan 2011 16:34:52 EST news215714057 A new study examining data on incidence trends, mortality rates and survival rates from the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) cancer registries indicates that the incidence of liver cancer in the United States tripled between 1975 and 2005. http://phys.org/news154191005.html Medicine & Health Wed, 18 Feb 2009 14:50:45 EST news154191005 In the largest study to date on the safety of ovarian preservation in women aged 45 and younger who were surgically treated for early-stage endometrial cancer, researchers have found that there is no survival benefit associated with surgical removal of the ovaries, compared to women whose ovaries were left intact. Leaving the ovaries in place could spare many women from the side effects of surgery-induced early menopause, such as hot flashes and vaginal dryness, as well as the long-term increased risk of heart disease, osteoporosis and hip fractures. http://phys.org/news152370327.html Medicine & Health Wed, 28 Jan 2009 13:05:48 EST news152370327
