Cancer cells are wily, well-traveled adversaries, constantly side-stepping treatments to stop their spread. But for the first time, scientists at the University of Michigan have decoded the molecular chatter that ramps certain cancer cells into overdrive and can cause tumors to metastasize throughout the body. http://medicalxpress.com/news/2013-04-decoded-molecular-messages-prostate-breast.html Cancer Tue, 30 Apr 2013 13:21:41 EST news286546894 Colorectal cancer is the second leading cause of cancer-related deaths in the United States. Once colorectal cancer has spread to other parts of the body, only 11 percent of patients will survive five years from the date of their diagnosis. Most colorectal cancers are adenocarcinomas—cancers that begin in cells that make and release mucus and other fluids. Adenocarcinomas begin as benign tumors called adenomas, which become malignant over time. By treating adenomas before they become cancerous, it could be possible to prevent colorectal cancer. http://medicalxpress.com/news/2013-04-drug-combinations-treatment-colorectal-tumors.html Cancer Sun, 07 Apr 2013 13:00:16 EST news284554964 UT Southwestern Medical Center scientists report the first successful blocking of tumor development in a genetic mouse model of an incurable human cancer. http://medicalxpress.com/news/2013-03-scientists-mouse-human-cancer.html Cancer Tue, 05 Mar 2013 12:16:31 EST news281708184 Large-scale genomic sequencing has revealed two DNA mutations that appear to drive about 15 percent of brain tumors known as meningiomas, a finding that could lead to the first effective drug treatments for the tumors, report scientists from Dana-Farber Cancer Institute and the Broad Institute. http://medicalxpress.com/news/2013-01-genomic-sequencing-mutant-drivers-common.html Genetics Tue, 22 Jan 2013 15:07:28 EST news278089642 Researchers conducting a preclinical study in mice successfully used targeted molecular therapy to block mostly untreatable nerve tumors that develop in people with the genetic disorder Neurofibromatosis 1 (NF1). http://medicalxpress.com/news/2012-12-molecular-therapy-untreatable-nf1-tumors.html Cancer Mon, 10 Dec 2012 12:00:15 EST news274359400 Johns Hopkins experts are recommending early post-surgical assessment—preferably within 24 hours—for trouble chewing and swallowing food, or speaking normally, among patients who have had benign tumors removed from the base of the brain. http://medicalxpress.com/news/2012-12-experts-urge-rapid-swallowing-voice.html Cancer Mon, 03 Dec 2012 12:01:13 EST news273758457 Meningiomas are a common type of benign brain tumor that sometimes grows dramatically in pregnant women.

They are benign tumors that occur in 60% of women by the age of 45 years and cause symptoms such as abdominal pain and discomfort, and abnormal bleeding, in about half of the cases. Fibroids are also an important cause of infertility. These tumors are the most common medical reason for hysterectomy. http://medicalxpress.com/news/2011-08-breakthrough-genetics-fibroids.html Medical research Thu, 25 Aug 2011 14:01:02 EST news233499231 Women who experience heavy periods, cramping, pain during sex, an urge to urinate frequently and even infertility may have a common disorder that affects African-American women three times more often than other women. This condition, called uterine fibroids, occurs when benign tumors grow in the uterus. Eighty percent of African-American women develop uterine fibroids by their late 40s, according to the National Institute of Environmental Health Sciences. http://medicalxpress.com/news/2011-08-african-american-women-fibroids.html Cancer Tue, 09 Aug 2011 10:50:27 EST news232103145
