Breast cancer survivors with poor physical health scores had an elevated risk of poorer cancer outcomes, including recurrence and death, according to the results of an observational study presented at the AACR 102nd Annual Meeting 2011, held April 2-6. http://phys.org/news221298681.html Medicine & Health Wed, 06 Apr 2011 08:51:41 EST news221298681 Results of the NIH-AARP Diet and Health Study revealed that diabetes is associated with lower risk of prostate cancer in men but with higher risk of other cancers in both men and women. The data, to be presented at the AACR 102nd Annual Meeting 2011, held here April 2-6, also showed an association between diabetes and higher cancer mortality rates. http://phys.org/news221068636.html Medicine & Health Sun, 03 Apr 2011 16:57:31 EST news221068636 A new report from the American Cancer Society says a large proportion of the 141,000 cases and 49,000 deaths from colorectal cancer expected in the United States this year could be prevented by increasing the use of established screening tests and by applying existing knowledge about colorectal cancer prevention. The report, Colorectal Cancer Facts & Figures 2011-2013, released during National Colon Cancer Awareness Month, notes there has been substantial progress in the last decade reducing colorectal cancer incidence and death rates in most population groups in the U.S., largely through the prevention and early detection of colorectal cancer through screening. But even more progress is possible by increasing access to and utilization of colorectal cancer screening tests; almost half of Americans 50 and older are not getting screened according to guidelines. http://phys.org/news218209277.html Medicine & Health Tue, 01 Mar 2011 14:00:01 EST news218209277 Despite the absence of Medicare coverage, hospital use of computed tomographic colonography (CTC), commonly referred to as virtual colonoscopy, is on the rise, according to a study in the March issue of the Journal of the American College of Radiology. Colorectal cancer is the second leading cause of cancer deaths in the U.S. CTC, a minimally invasive alternative to optical colonoscopy for colorectal cancer screening, employs virtual reality technology to produce a 3-D visualization that permits a thorough evaluation of the entire colon and rectum. http://phys.org/news218175069.html Medicine & Health Tue, 01 Mar 2011 05:20:03 EST news218175069 An international team of researchers has found that the use of bisphosphonates - drugs already taken by millions of healthy women to prevent bone-loss - for more than one year was associated with a 50 percent reduction in the risk of postmenopausal colorectal cancer. The results were published this week in the Journal of Clinical Oncology. http://phys.org/news217090776.html Medicine & Health Wed, 16 Feb 2011 15:00:00 EST news217090776 University of Queensland Diamantina Institute PhD student, Veronique Chachay, hopes to determine if a nutrient found in grape skin could hold the key to better managing non-alcoholic fatty liver disease (NAFLD). http://phys.org/news216300531.html Medicine & Health Mon, 07 Feb 2011 11:40:01 EST news216300531 Researchers from the Kimmel Cancer Center at Jefferson and two other institutions have discovered new evidence that suggests the "longevity" protein SIRT1, known for its life-spanning effects in different species, can inhibit the development of a known precursor to prostate cancer, prostatic intraepithelial neoplasia (PIN). http://phys.org/news214136326.html Medicine & Health Thu, 13 Jan 2011 10:19:03 EST news214136326 Almost half of cervical and colorectal cancers in the United States are diagnosed in the late stages of the disease when treatment is unlikely to help, a US government survey said Wednesday. http://phys.org/news209834873.html Medicine & Health Wed, 24 Nov 2010 16:00:01 EST news209834873 Women being treated for breast cancer with aromatase inhibitors may experience extremely low estrogen levels resulting in a wide variety of side effects that a typical postmenopausal woman without cancer may not experience. http://phys.org/news208532791.html Medicine & Health Tue, 09 Nov 2010 14:00:03 EST news208532791 Allopurinol, a relatively inexpensive anti-gout medication that has been on the market for more than 20 years, may have some activity against colorectal adenomas, according to data presented at the Ninth Annual AACR Frontiers in Cancer Prevention Research Conference, held here Nov. 7-10, 2010. http://phys.org/news208443440.html Medicine & Health Mon, 08 Nov 2010 12:57:36 EST news208443440 (PhysOrg.com) -- Two new vitamin D studies from the University of Rochester Medical Center suggest intriguing ties between a deficiency of D and breast and colon cancer, particularly among African Americans. http://phys.org/news206894735.html Medicine & Health Thu, 21 Oct 2010 15:45:52 EST news206894735 Women in South Africa who underwent human papillomavirus (HPV) DNA-based testing or visual inspection of the cervix followed by treatment of test-positive women with cryotherapy had a statistically significant reduction in high grade cervical cancer precursors, compared with women in a control group, according to a study published online Sept. 30 in The Journal of the National Cancer Institute. http://phys.org/news205082694.html Medicine & Health Thu, 30 Sep 2010 16:25:58 EST news205082694 Although overall mortality from cancer is decreasing in the European Union, its incidence increased by almost 20%, from 2.1 million new cases in 2002 to 2.5 million in 2008, says a special issue [1] of the European Journal of Cancer (the official journal of ECCO - the European CanCer Organisation) on cancer prevention, published today. http://phys.org/news203572801.html Medicine & Health Mon, 13 Sep 2010 05:00:54 EST news203572801 Girls eating a high-fat diet during puberty, even those who do not become overweight or obese, may be at a greater risk of developing breast cancer later in life, according to Michigan State University researchers. http://phys.org/news202487777.html Medicine & Health Tue, 31 Aug 2010 16:00:05 EST news202487777 Once thought to be a problem primarily in the developed world, cancer is now a leading cause of death and disability in poorer countries.

Researchers say time spent sitting was independently associated with total mortality, regardless of physical activity level. They conclude that public health messages should promote both being physically active and reducing time spent sitting. The study appears early online in the American Journal of Epidemiology. http://phys.org/news199011576.html Medicine & Health Thu, 22 Jul 2010 09:59:51 EST news199011576 (PhysOrg.com) -- If you constantly pop pills and still suffer from irritating heartburn, there may be an underlying problem more effectively -- and safely -- addressed with surgery. http://phys.org/news198487747.html Medicine & Health Fri, 16 Jul 2010 09:00:01 EST news198487747 The European Association of Urology reiterated that it does not recommend a mass screening policy in Europe for men who are concerned over prostate cancer, a stance which reflects the position it issued last year regarding prostate cancer screening. http://phys.org/news190895017.html Medicine & Health Mon, 19 Apr 2010 12:10:07 EST news190895017 Higher rates of colorectal cancer incidence and mortality experienced by African-Americans may be driven largely by differences in health care utilization, and less by biology, according to a new study led by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health. http://phys.org/news189794025.html Medicine & Health Tue, 06 Apr 2010 17:34:20 EST news189794025 A new heart-healthy, essential omega-3 fatty acid is about to improve an American pantry staple: soybean oil.
