Human papillomavirus, or HPV, which can cause cervical cancer in women, is also known to cause anal cancer in both women and men. Now, a study led by researchers at the UCLA School of Nursing has found that older HIV-positive men who have sex with men are at higher risk of becoming infected with the HPVs that most often cause anal cancer.
For the first time, researchers at Umea University have succeeded in showing how the DNA polymerase epsilon enzyme builds new genomes. The detailed image produced by these researchers shows how mutations that can contribute to the development of colorectal cancer and cervical cancer lead to changes in the structure of the protein.
Scientists and surgeons at Princess Margaret Cancer Centre have discovered a promising new approach to treating colorectal cancer by disarming the gene that drives self-renewal in stem cells that are the root cause of disease, resistance to treatment and relapse. Colorectal cancer is the third leading cause of cancer-related death in the Western world.
Researchers in Canada found that switching off a gene in the cancer stem cells that drive colon cancer stops them from being able to renew themselves. They say their study offers a starting point to treatments that could shut the cancer down.Cancer stem cells are cells that have the ability to differentiate into all the types of cell that exist in that type of tumor.
The protein in cells that most often drives the development of cancers has eluded scientists' efforts to block it for three decades - until now.Using a new strategy, UC San Francisco researchers have succeeded in making small molecules that irreversibly target a mutant form of this protein, called ras, without binding to the normal form.
Researchers at the University of California, San Diego School of Medicine say metastatic colorectal cancer patients of African-American descent are less likely to be seen by cancer specialists or receive cancer treatments. This difference in treatment explains a large part of the 15 percent higher mortality experienced by African-American patients than non-Hispanic white patients.
New results are in from the Women's Health Initiative (WHI) Calcium plus Vitamin D Supplementation Trial. These findings assess the effects on hip fracture and colorectal cancer incidence among 30,000 postmenopausal women nearly five years after the seven-year period of calcium plus vitamin D supplementation ended.
Chronic inflammation has long been known as a key risk factor for cancer - particularly colon cancer - but the exact mechanisms of how inflammation heightens the immune response, and ultimately influences the initiation and progression of cancer have remained elusive. It is well established that anti-inflammatory drugs, like aspirin, reduce the risk of colorectal cancer.
Patients Report High-Quality Care in Federally Supported Health CentersPatients seen in federally supported community health centers in the United States generally report high quality of care, according to data from a nationally representative survey of more than 4,500 patients.
VolitionRx Limited (OTC: VNRX), a life sciences company focused on developing blood-based diagnostic tests for different types of cancer, has announced the publication of preliminary data from an ongoing independent trial of one of its NuQ® assays. Priv.-Doz. Dr.
Researchers from Faculty of Health and Medical Sciences, University of Copenhagen, have characterized a genetic aberration on a group of colorectal cancer patients. The discovery gives hope for a new and efficient treatment of colorectal cancer, which is a frequent and often fatal disease. The research was recently published in Scandinavian Journal of Gastroenterology.
For patients who fail to respond to current first-line and second-line treatments for colorectal cancer liver metastases (also known as salvage patients), radioembolization with Y-90 microspheres could extend survival according to new research published in the November issue of The Journal of Nuclear Medicine.
Citizenship, particularly for non-U.S. natives, largely determines a woman's odds of having a mammogram and being screened for cervical and colorectal cancer, according to researchers at Penn State.
Transferring the gut microbes from a mouse with colon tumors to germ-free mice makes those mice prone to getting tumors as well, according to the results of a study published in mBio®, the online open-access journal of the American Society for Microbiology. The work has implications for human health because it indicates the risk of colorectal cancer may well have a microbial component.
Tumors become highly malignant when they acquire the ability to colonize other tissues and form metastases. LMU researchers have identified a factor that promotes metastasis of colon tumors - and presents a possible target for therapy.
Scientists have known for some time that inflammation influences the development of colorectal cancer, but now, a new study suggests that gut microbes may also play a role.
Diagnosing colorectal cancer (CRC) is complex; it relies on significant invasive tests and subjective evaluations. This process may soon become much easier thanks to a medical breakthrough by scientists at the Research Institute of the McGill University Health Centre (RI-MUHC).
Men who spend the most time engaged in sedentary behaviors are at greatest risk for recurrence of colorectal adenomas, benign tumors that are known precursors of colorectal cancers, according to results presented at the 12th Annual AACR International Conference on Frontiers in Cancer Prevention Research.
Lower cancer screening rates and increased risk of preventable disease affect South Asians in Peel, Canada
South Asian-Canadians living in Peel Region may be 15 per cent less likely than other Ontarians to be screened for breast, cervical or colorectal cancer, making them much more vulnerable to cancer deaths.The findings were published in a report by researchers at the Centre for Research on Inner City Health.Peel Region - a municipality comprised of Brampton, Caledon and Mississauga - has 1.
A University of Colorado Cancer Center study published in the journal PLOS ONE shows that when colorectal cancer is targeted by the drug bevacizumab (Avastin), tumors may switch dependence from VEGF-A, which is targeted by the drug, to related growth factors in including VEGF-C, VEGF-D and placental growth factor.
