Cancer researchers at the University of Oklahoma Health Sciences Center have found a way to turn ineffective new cancer drugs into cancer-fighters. By using their patented chemical compound, SHetA2, researchers tricked cancer cells into responding to new treatments and undergoing cell suicide. The research appears in the journal Gynecologic Oncology. http://www.physorg.com/news178905949.html Medicine & Health Tue, 01 Dec 2009 16:06:26 EST news178905949 (PhysOrg.com) -- Applying sunscreen on a regular basis not only prevents cancer, but will save the government money. http://www.physorg.com/news178789614.html Medicine & Health Mon, 30 Nov 2009 07:51:44 EST news178789614 Men with lower cholesterol are less likely than those with higher levels to develop high-grade prostate cancer - an aggressive form of the disease with a poorer prognosis, according to results of a Johns Hopkins collaborative study. http://www.physorg.com/news176470906.html Medicine & Health Tue, 03 Nov 2009 12:20:01 EST news176470906 A new report from an American Cancer Society scientific advisory subcommittee on cancer and the environment says exposure to carcinogens should be minimized or eliminated whenever feasible, and calls for new strategies to more effectively and efficiently screen the large number of chemicals to which the public is exposed. The report was created as part of an initiative to address ongoing and emerging issues related to environmental pollutants and cancer, and to articulate the American Cancer Society's principles, objectives, and potential roles regarding environmental pollution and cancer prevention. http://www.physorg.com/news175930521.html Medicine & Health Wed, 28 Oct 2009 07:10:01 EST news175930521 For the first time, researchers at Fred Hutchinson Cancer Research Center have demonstrated that it is possible to successfully recruit and retain a large number of adolescent smokers from the general population into a smoking intervention study and, through personalized, proactive telephone counseling, significantly impact rates of six-month continuous quitting. These findings, by Arthur V. Peterson Jr., Ph.D., Kathleen A. Kealey and colleagues, are reported in a pair of papers in the Oct. 12 "Advance Access" online edition of the Journal of the National Cancer Institute. http://www.physorg.com/news174584678.html Medicine & Health Mon, 12 Oct 2009 16:46:01 EST news174584678 (AP) -- Texas gave birth to the modern oil industry, invented the handheld calculator and sent man to the moon. But can the Lone Star State cure cancer? http://www.physorg.com/news173724804.html Medicine & Health Fri, 02 Oct 2009 18:40:01 EST news173724804 How you eat may be just as important as how much you eat, if mice studies are any clue. http://www.physorg.com/news168612990.html Medicine & Health Tue, 04 Aug 2009 14:20:08 EST news168612990 Researchers at the University of Maryland Marlene and Stewart Greenebaum Cancer have found that head and neck cancer patients who test positive for the human papillomavirus (HPV) have much better survival rates than patients who don't have the virus, according to a new study in the journal Cancer Prevention Research. The researchers also discovered that blacks in the study had a very low rate of HPV infection, and consequently worse survival, which may explain why African-American patients traditionally have had a poor prognosis for head and neck cancer. http://www.physorg.com/news168095606.html Medicine & Health Wed, 29 Jul 2009 14:50:02 EST news168095606 For the last six years, doctors have faced a dilemma about whether to treat men at risk of prostate cancer with the drug finasteride. On one hand, the drug had been shown to prevent cancer in about one of every four patients who received it. On the other, those who did develop cancer while on the drug were 25 percent more likely to have a more aggressive form of the disease. http://www.physorg.com/news166200841.html Medicine & Health Tue, 07 Jul 2009 16:10:02 EST news166200841 A Kansas State University researcher is studying the potential health benefits of a specially bred purple sweet potato because its dominant purple color results in an increased amount of anti-cancer components. http://www.physorg.com/news165499992.html Medicine & Health Mon, 29 Jun 2009 13:30:02 EST news165499992 In 2004, researchers at the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center announced a crucial discovery in the understanding of cellular aging. They found that as cells and tissues age, the expression of a key protein, called p16INK4a, dramatically increases in most mammalian organs. Because p16INK4a is a tumor suppressor protein, cancer researchers are interested in its role in cellular aging and cancer prevention. http://www.physorg.com/news164360505.html Medicine & Health Tue, 16 Jun 2009 08:42:15 EST news164360505 Restricting carbohydrates, regardless of weight loss, appears to slow the growth of prostate tumors, according to an animal study being published this week by researchers in the Duke Prostate Center. http://www.physorg.com/news162563042.html Medicine & Health Tue, 26 May 2009 13:24:41 EST news162563042 A protein that plays a key role in tumor formation, oxygen metabolism and inflammation is involved in a pathway that extends lifespan by dietary restriction. The finding, which appears in the May 22, 2009 edition of the on-line journal PLoS Genetics, provides a new understanding of how dietary restriction contributes to longevity and cancer prevention and gives scientists new targets for developing and testing drugs that could extend the healthy years of life. http://www.physorg.com/news162215715.html Medicine & Health Fri, 22 May 2009 12:55:40 EST news162215715 The commonly used prescription statin drugs may have a protective effect in the prevention of liver cancer and lead to a reduction in the need for gallbladder removals, according to two studies published in Gastroenterology. As millions of Americans use statins each day to help lower their cholesterol and risk of heart disease, researchers are learning of the beneficial effects these drugs may have on gastrointestinal disorders.
