When Cancer Runs in the Family
Almost all tumor types have a genetically based form Most cancers occur sporadically. At least 5.5 percent of cancer cases are based on a genetic predisposition. These are usually identified because first-degree relatives develop the same type of tumor. So far, scientists have presumed that only a few types of tumor have such a familial form.... view more...

New predictive tool can help determine treatment of breast cancer patients
A new predictive measurement, called a PEPI score, could bring good news to many women diagnosed with early stage breast cancer - a low PEPI (preoperative endocrine prognostic index) score could show that they have little risk of relapse and can safely avoid chemotherapy after surgery. view more (2008-09-24)
Autoimmune response can induce pancreatic tumor rejection
Immune responses are capable of killing tumors before they can be directed toward normal body tissue, according to new scientific findings published in Cancer Research, a journal of the American Association for Cancer Research. view more (2009-09-09)
New mechanism identified for resistance to targeted lung cancer drugs
An international research team, led by investigators from the Massachusetts General Hospital (MGH) Cancer Center and Dana-Farber Cancer Institute (DFCI), has found a new way that some lung tumors become resistant to treatment with targeted therapy drugs like Iressa and Tarceva. view more (2007-04-27)
A link between mitochondria and tumor formation in stem cells
Researchers report on a previously unknown relationship between stem cell potency and the metabolic rate of their mitochondria -a cell's energy makers. Stem cells with more active mitochondria also have a greater capacity to differentiate and are more likely to form tumors. view more (2008-10-13)
Scientists identify pancreatic cancer stem cells
Researchers at the University of Michigan Medical Center have, for the first time, identified human pancreatic cancer stem cells. Their work indicates that these cells are likely responsible for the aggressive tumor growth, progression, and metastasis that define this deadly cancer. view more (2007-02-01)
Duke develops nano-scale drug delivery for chemotherapy
Going smaller could bring better results, especially when it comes to cancer-fighting drugs. view more (2009-11-02)
Neurotransmitters signal aggressive cancer, offer potential for early diagnosis
Nerves talk to each other using chemicals called neurotransmitters. One of those "communication chemicals," aptly named GABA (gamma amino butyric acid), shows up in unusually high amounts in some aggressive tumors, according to a new study from Washington University School of Medicine in St. Louis. view more (2005-07-05)
UNC scientists identify growth factor as possible cancer drug target
To grow and spread, tumors need new blood vessels, a process called angiogenesis. view more (2009-06-10)
Taking folic acid does not reduce risk of precancerous colon tumors
Taking folic acid supplements does not reduce the risk of developing precancerous tumors in the colon and may even increase the risk, a new study has found. view more (2007-06-11)
Cancer stem cells spur glioma Angiogenesis, could hold key to brain tumor therapy
Stem cell-like glioma cancer cells that share many characteristics with normal stem cells propel the lethal growth of brain cancers by promoting tumor blood vessel formation, and may hold the key to treating these deadly cancers. view more (2006-08-15)
New hope for cancer comes straight from the heart
Digitalis-based drugs like digoxin have been used for centuries to treat patients with irregular heart rhythms and heart failure and are still in use today. In the Dec. 16 issue of the Proceedings of the National Academy of Sciences, researchers at the Johns Hopkins University School of Medicine now report that this same class of drugs may hold... view more...

Computer Model Predicts Brain Tumor Growth and Evolution
Researchers from Brown University and other institutions have developed a computational computer model of how brain tumors grow and evolve. view more (2009-05-19)
Study: Why Some Prostate Cancer Returns
The majority of men who receive one of the standard treatments for localized prostate cancer - surgery or radiation therapy - have an excellent outcome. view more (2009-05-28)
Nanoparticles carry chemotherapy drug deeper into solid tumors
A new drug delivery method using nano-sized molecules to carry the chemotherapy drug doxorubicin to tumors improves the effectiveness of the drug in mice and increases their survival time. view more (2007-06-27)
Breast cancer is more aggressive in African-American women
African American women are diagnosed with breast cancer at a younger age and have larger tumors and more lymph node involvement than Caucasian women, a Yale School of Medicine researcher reported today. view more (2007-10-30)
State's first single incision robotic kidney removal
For the first time in Michigan, a diseased kidney has been surgically removed at Henry Ford Hospital using highly sophisticated 3D robotics through a single incision. view more (2008-08-26)
Researchers effectively treat tumors with use of nanotubes
By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. view more (2009-08-04)
Received Truth Turned On End In Cancer Research
It has long been the accepted view of cancer researchers that there is a difference between the mechanism behind the development of leukemias, on the one hand, and solid tumors like breast cancer, prostate cancer, gastrointestinal cancer, etc, on the other. A research team at the Section for Clinical Genetics at Lund University in Sweden is now... view more... (2004-04-06)
Penn researchers discover a molecular pathway that leads to recurrence of breast cancer
(Philadelphia, PA)-Using a recently developed mouse model of breast cancer, a team from the University of Pennsylvania School of Medicine has shown that Snail, a molecule normally important in embryonic development, can promote breast cancer recurrence. view more (2005-09-20)
