Previously unseen switch regulates breast cancer response to estrogen
A tiny modification called methylation on estrogen receptors prolongs the life of these growth-driving molecules in breast cancer cells, according to research by scientists at Emory University's Winship Cancer Institute. view more (2008-05-09)
Patients regain cognitive function after radiation for brain tumors
Patients who suffer from low-grade brain tumors are able to regain normal cognitive function after receiving radiation therapy to shrink their tumor. view more (2005-11-16)
Bright tumors, dim prospects
It doesn't matter how small or large it is, if a cervical tumor glows brightly in a PET scan, it's apt to be more dangerous than dimmer tumors. That's the conclusion of a new study of cervical cancer patients at Washington University School of Medicine in St. Louis. view more (2007-09-14)
Tumor mutations can predict chemo success
New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to chemotherapy. view more (2009-08-07)
Fly with brain tumor may shed light on cancer causing genes
A study showing how the expression of genes changes when the brain tissue of fruit flies becomes cancerous is published this week in BMC Genomics. As the function of many of these genes is conserved across evolution, the researchers expect their results will help us to understand why human brain tumors develop. The causes of brain tumor... view more... (2004-04-14)
Molecular differences between early and advanced melanomas could provide new drug targets
The cell-signaling molecule Akt is a primary trigger that leads malignant melanomas on the skin's surface to begin growing vertically beneath the skin and turn into deadly invasive cancers, scientists have found. view more (2007-03-13)
Mass. General study finds potential ovarian cancer stem cells
Massachusetts General Hospital (MGH) researchers have identified potential ovarian cancer stem cells, which may be behind the difficulty of treating these tumors with standard chemotherapy. view more (2006-07-24)
Black women with uterine cancers more likely to die than white patients
Black women with cancers of the uterus are less likely to survive the disease than white women, and relatively little progress has been made over the past two decades to narrow this racial difference. That is the conclusion of a new study published in the March 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. view more (2009-02-09)
Why don't brain tumors respond to medication?
Malignant brain tumors often fail to respond to promising new medication. Researchers in Heidelberg have discovered a mechanism and a tumor marker for the development of this resistance. view more (2009-09-01)
OHSU Knight Cancer Institute researcher: study may result in more targeted drugs for GIST
According to Oregon Health & Science University Knight Cancer Institute researchers, there is strong evidence that patients can have varying clinical responses to medications depending on the specific makeup of their cancer. view more (2008-11-13)
Blood protein may hold key to stopping tumor growth in cancer patients
A recent discovery by researchers at Wake Forest University School of Medicine could clear the way for a new drug that inhibits tumor growth in cancer patients and could potentially help in the healing of wounds. view more (2009-04-01)
Penn researchers identify natural tumor suppressor
Researchers from the University of Pennsylvania School of Medicine have identified a key step in the formation - and suppression - of esophageal cancers and perhaps carcinomas of the breast, head, and neck. view more (2008-09-10)
Cedars-Sinai researchers discover treatment for deadly brain tumors and infections
In a study published in the March 15 issue of The Journal of Immunology, researchers at Board of Governors' Gene Therapeutics Research Institute at Cedars-Sinai Medical Center have developed a way to overcome immune privilege in the brain to eradicate potentially deadly brain tumors such as glioblastoma multiforme and other types of brain... view more...

Study finds endoscopic brain surgery pioneered in Pittsburgh effective in children with tumors
A first-of-its-kind study published in the February issue of the Journal of Neurosurgery: Pediatrics suggests endoscopic brain surgery, pioneered by surgeons at the University of Pittsburgh Medical Center, has the potential to be safer and often more effective than conventional surgery in children with life-threatening conditions. view more (2007-02-09)
Preclinical study shows chronic stress agitates ovarian cancer; reducing stress slows tumor growth
When mice with ovarian cancer are stressed, their tumors grow and spread more quickly, but that effect can be blocked using a medication commonly prescribed for heart disease. view more (2006-07-24)
Bone marrow stem cell co-transplantation prevents embryonic stem cell transplant-associated tumors
Transplanted embryonic stem cells are recognized as a potential treatment for patients suffering from the effects of spinal cord injury (SCI). view more (2009-05-12)
Research suggests that immune response protects against brain tumor development
In their quest to determine whether immune system surveillance guards against brain tumor development, researchers at The University of Texas M. D. Anderson Cancer Center have found that allergies and asthma that stimulate inflammation may be protective, but use of antihistamines to control the inflammation could eliminate that protection. view more (2006-04-03)
Pitt research indicates new virus is culprit, not bystander, in deadly skin cancer
University of Pittsburgh scientists are uncovering more evidence that a virus they recently discovered is the cause of Merkel cell carcinoma, an aggressive and deadly form of skin cancer. view more (2008-09-23)
Multicenter study nets new lung tumor-suppressor gene
Collaborating scientists in Boston and North Carolina have found that a particular gene can block key steps of the lung cancer process in mice. view more (2007-08-06)
Finding protection from tumor growth in unexpected places
Researchers have discovered that an enzyme commonly involved in regulating blood pressure also provides protection from tumor growth when strongly expressed in immune cells. view more (2007-06-06)
