Tumors need a healthy supply of blood to grow and spread. Researchers at the Stanford University School of Medicine have identified a molecule that regulates blood vessel growth that is often found at less-than-normal levels in human tumors. Blocking the expression of the molecule, called PHD2, allows human cancer cells to grow more quickly when implanted into mice and increases the number of blood vessels feeding the tumor. http://phys.org/news163084699.html Medicine & Health Mon, 01 Jun 2009 14:19:16 EST news163084699 (AP) -- New research finds that people who had radiation treatments for cancer as children are less likely than the general public or even their healthy siblings to get recommended screening tests. http://phys.org/news163072496.html Medicine & Health Mon, 01 Jun 2009 10:55:34 EST news163072496 (PhysOrg.com) -- UCLA scientists have linked for the first time intestinal inflammation with systemic chromosome damage in mice, a finding that may lead to the early identification and treatment of human inflammatory disorders, some of which increase risk for several types of cancer. http://phys.org/news163044358.html Medicine & Health Mon, 01 Jun 2009 03:06:22 EST news163044358 US cancer experts are preparing to focus on new developments in making treatment ever more personalized, right down to the molecular level, at their main annual gathering this weekend. http://phys.org/news162821483.html Medicine & Health Fri, 29 May 2009 13:12:52 EST news162821483 Novel chemotherapy and biological agents for metastatic colorectal cancer, combined with surgical advances in liver resection, have resulted in a dramatic increase in survival for patients with advanced disease, according to researchers at The University of Texas M.

The trial determined that patients with chronic lymphocytic leukemia (CLL) can tolerate the chemical fairly well when high doses are administered in capsule form and that lymphocyte count was reduced in one-third of participants. The findings appear today online in the Journal of Clinical Oncology. http://phys.org/news162578349.html Medicine & Health Tue, 26 May 2009 17:41:23 EST news162578349 (PhysOrg.com) -- Research from the Northwestern University Feinberg School of Medicine has found that a less toxic, solvent-free chemotherapy drug more effectively prevents the progression of metastatic breast cancer and has fewer side effects than a commonly used solvent-based drug. http://phys.org/news162572989.html Medicine & Health Tue, 26 May 2009 16:10:27 EST news162572989 Fox Chase Cancer Center researchers have discovered that low-oxygen regions in prostate tumors can be used to predict a rise in prostate-specific antigen (PSA) levels, a marker of tumor recurrence in prostate cancer.
