Cancer is not just one disease, but a large group of almost one hundred diseases. Its two main characteristics are uncontrolled growth of the cells in the human body and the ability of these cells to migrate from the original site and spread to distant sites. If the spread is not controlled, cancer can result in death.
Grape seed extract kills laboratory leukemia cells, proving value of natural compounds. – An extract from grape seeds forces laboratory leukemia cells to commit cell suicide, according to researchers from the University of Kentucky. They found that within 24 hours, 76 percent of leukemia cells had died after being exposed to the extract.
Few DNA repair genes maintain association with cancer in field synopsis – Variants of numerous DNA repair genes initially appeared to be statistically significantly associated with cancer risk in epidemiological studies.
Common food additive found to increase risk and speed spread of lung cancer – New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages, and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease.
Annals colonoscopy study underscores importance of quality standards. Cancer of the colon should be one of the easiest tumors to prevent. – Screening colonoscopy is associated with fewer deaths from colorectal cancer, and the association is primarily limited to deaths from cancer developing in the left side of the colon, revealed by researchers.
Low income men more likely to be diagnosed with advanced prostate cancer – Low-income men are more likely to present with advanced prostate cancers, most likely because they don’t receive screening services shown to reduce the diagnosis of later-stage cancers, a UCLA study found.
Colorectal cancer is the third most common form of cancer and the fourth most frequent cause of cancer deaths worldwide. Cigarette smoking is significantly associated with colorectal cancer incidence and mortality. – An analysis of previous studies indicates that smoking is significantly associated with an increased risk for colorectal cancer and death, according to an article in the December 17 issue of JAMA.
Diet loaded with fruits, vegetables and fiber may cut risk of breast cancer recurrence in women without hot flashes. – A secondary analysis of a large, multicenter clinical trial has shown that a diet loaded with fruits, vegetables and fiber and somewhat lower in fat compared to standard federal dietary recommendations cuts the risk of recurrence in a subgroup of early-stage breast cancer survivors ? women who didn’t have hot flashes ? by approximately 31 percent.
Colonoscopy significantly reduces death from left-sided colon cancer but not from right-sided. Physicians should advise patients of test limitations. – A new study finds that colonoscopy is strongly associated with fewer deaths from colorectal cancer. However, the risk reduction appears to be entirely due to a reduction in deaths from left-sided cancers.
Men with wives, significant others more likely to be screened for prostate cancer – Although the link between early screening and prostate cancer survival is well established, men are less likely to go for early screening unless they have a wife or significant other living with them, according to a study published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.
New breast imaging technology – breast specific gamma imaging – BSGI targets hard-to-detect cancers – Breast-specific gamma imaging (BSGI) is effective in the detection of cancers not found on mammograms or by clinical exam, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
ASGE encouraged by drop in colorectal cancer deaths. Prevention through screening and removal of precancerous polyps among key factors in saving lives. – The American Society for Gastrointestinal Endoscopy (ASGE) heralds the recent news of a decline in U.S. cancer deaths and incidence rates, with colorectal cancer among the top three cancers with significant declines.
Some breast cancers detected by repeated mammographic screening would not persist to be detectable by a single mammogram at the end of 6 years, and this raises the possibility that the natural course of some screen-detected invasive breast cancers is to spontaneously regress. – Breast cancer rates increased significantly in four Norwegian counties after women there began undergoing mammography every two years, according to a report in the November 24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
