(PhysOrg.com) -- Smoking persists as a major risk factor for death from heart disease and cancer in adults who already have heart disease and receive good medical therapy, according to research reported in Circulation: Journal of the American Heart Association. http://phys.org/news178219773.html Medicine & Health Mon, 23 Nov 2009 17:40:05 EST news178219773 Risk of bladder cancer for smokers has increased since the mid-1990s, with a risk progressively increasing to a level five times higher among current smokers in New Hampshire than that among nonsmokers in 2001-2004, according to a new study published online November 16 in the Journal of the National Cancer Institute. Furthermore, researchers found that among individuals who smoked the same total number of cigarettes over their lifetime, smoking fewer cigarettes per day for more years may be more harmful than smoking more cigarettes per day for fewer years. http://phys.org/news177620245.html Medicine & Health Mon, 16 Nov 2009 22:30:01 EST news177620245 Jewish survivors of World War II who were potentially exposed to the Holocaust are at a higher risk for cancer occurrence, according to a new study published online October 26 in the Journal of the National Cancer Institute. http://phys.org/news175793717.html Medicine & Health Mon, 26 Oct 2009 17:00:09 EST news175793717 There is clear evidence that lifestyle choices affect the incidence and treatment of cancer, according to a study published in the current issue of American Journal of Lifestyle Medicine (AJLM). http://phys.org/news173020164.html Medicine & Health Thu, 24 Sep 2009 14:30:01 EST news173020164 A team of scientists led by researcher Brenda Hernandez, Ph.D., M.P.H.—an assistant professor at the University of Hawai'i at Mānoa's Cancer Research Center of Hawai'i—has reported that body mass in younger and older adulthood, and weight gain between these life periods, may influence a man's risk for prostate cancer. This risk varies among different ethnic groups, according to findings reported in a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. http://phys.org/news171910086.html Medicine & Health Fri, 11 Sep 2009 17:48:17 EST news171910086 Johns Hopkins engineers have devised innovative computer software that can sift through hundreds of genetic mutations and highlight the DNA changes that are most likely to promote cancer. The goal is to provide critical help to researchers who are poring over numerous newly discovered gene mutations, many of which are harmless or have no connection to cancer. According to its inventors, the new software will enable these scientists to focus more of their attention on the mutations most likely to trigger tumors. http://phys.org/news171046783.html Medicine & Health Tue, 01 Sep 2009 18:10:03 EST news171046783 Body mass in younger and older adulthood, and weight gain between these periods of life, may influence a man's risk for prostate cancer.

Although genetic factors are important, there is considerable evidence that breast cancer risk is related to modifiable lifestyle factors, such as physical activity, body weight, alcohol intake, and dietary choices. The September 2009 issue of The American Journal of Clinical Nutrition reports the results of 3 human studies designed to better delineate the relation between animal foods and breast cancer risk. http://phys.org/news169472896.html Medicine & Health Fri, 14 Aug 2009 13:02:44 EST news169472896 For many people, summer festivities would be terribly un-festive without the sizzle, the smoke, and the tantalizing smell of meat being barbecued.

Increasingly, however, as the already high costs of cancer care continue to rise, a full view of the patient's welfare must also take into account the economic impact of the treatment on the patient and his or her family. http://phys.org/news162562367.html Medicine & Health Tue, 26 May 2009 13:13:17 EST news162562367 The risk of developing breast cancer due to taking hormone replacement therapy appears to be the same for women with a family history of the disease and without a family history, a University of Rochester Medical Center study concluded. http://phys.org/news161954459.html Medicine & Health Tue, 19 May 2009 12:21:22 EST news161954459 A unique mother-daughter study that used magnetic resonance to measure breast density in younger women shows that percent of breast water could be linked to the risk of breast cancer in middle age and older. http://phys.org/news160275336.html Medicine & Health Thu, 30 Apr 2009 01:55:57 EST news160275336 Dietary acrylamide was not associated with an increased risk of lung cancer, according to data from a large prospective case-cohort study in the April 28 online issue of the Journal of the National Cancer Institute. http://phys.org/news160154347.html Medicine & Health Tue, 28 Apr 2009 16:23:04 EST news160154347 Genetics plays a key role in determining risk for colorectal cancer, the second leading cause of cancer-related deaths in the United States. Several common genetic markers have been found to be associated with the disease, but finding the biological events that lead to cancer can be much more difficult. In a study published online in Genome Research, scientists have identified a common genetic variation associated with the risk of colorectal cancer and its functional implications, shedding new light on the basis of this deadly disease. http://phys.org/news159728950.html Medicine & Health Thu, 23 Apr 2009 18:09:42 EST news159728950 A new federally funded University of Pennsylvania School of Medicine study aims to learn whether women at high risk of breast cancer can use exercise to meaningfully reduce their risk of getting the disease. Building on evidence that reducing estrogen in the body reduces cancer risk, and that elite female athletes experience a drop in estrogen levels that often cause them to stop ovulating and menstruating, the WISER Sister trial will investigate two different levels of regular treadmill exercise as a possible intervention for breast cancer risk reduction. http://phys.org/news157903317.html Medicine & Health Thu, 02 Apr 2009 15:02:21 EST news157903317 Patients who undergo numerous CT scans over their lifetime may be at increased risk for cancer, according to a study published in the April issue of Radiology. http://phys.org/news157709697.html Medicine & Health Tue, 31 Mar 2009 09:15:29 EST news157709697 Asian-American women who ate higher amounts of soy during childhood had a 58 percent reduced risk of breast cancer, according to a study published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research. http://phys.org/news157127513.html Medicine & Health Tue, 24 Mar 2009 15:32:45 EST news157127513 Chinese women who ate mushrooms and drank green tea significantly cut their risk of breast cancer and the severity of the cancer in those who did develop it, an Australian researcher said Wednesday. http://phys.org/news156610089.html Medicine & Health Wed, 18 Mar 2009 15:48:26 EST news156610089 Women whose cells harbor harmful mutations in the BRCA genes are likely to view preventive mastectomy as the best way to reduce their risk and fears of developing breast cancer, despite other, less drastic options available. That is the conclusion of a new study published in the April 1, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study's findings could help physicians and other clinicians as they discuss test results with women who undergo BRCA gene testing. http://phys.org/news155810166.html Medicine & Health Mon, 09 Mar 2009 09:36:59 EST news155810166 Men and women who consume two or more alcoholic drinks a day could increase their risk of developing pancreatic cancer, according to a study published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research. http://phys.org/news155309915.html Medicine & Health Tue, 03 Mar 2009 13:39:03 EST news155309915 Europeans with the least education have a higher incidence of lung cancer compared with those with the highest education.
