Firefighters face increased risk for certain cancers

...icular, prostate, skin, brain, rectum, stomach and colon cancer, non-Hodgkin's lymphoma, multiple myeloma and malignant melanoma--were associated with firefighting on varying levels of increased risk. "There's a critical and immediate need for additional protective equipment to help firefighters avoid i...

Light-based probe 'sees' early cancers in first tests on human tissue

...eath, but that cancer might have originated in the colon or other site of epithelial tissue," said Adam Wax, professor of biomedical engineering. "Being able to detect pre-cancer in epithelial tissues would therefore help prevent all types of cancer by catching it early, before it has a chance to develop f...

Magnetic system could be key to surgery without scars

...ch now inserts the instruments through the throat, colon or vagina. “The current state of the art for laparoscopic surgery requires four or five holes. The question behind this is, can we do the surgery through only one hole and can we hide the hole in a cosmetically advantageous or less painful locatio...

Scientists identify a gene that may suppress colorectal cancer

...utated gene, the incidence of small intestinal and colon polyps were reduced by about 90%. “This gene may ... region that often exhibits genetic alterations in colon tumors,?says Dr. Linda Siracusa, the other co-senior investigator on the project. “A better understa...

Antibody signal may redirect inflammation to fuel cancer

...w that inflammation accelerates skin, cervical and colon cancer, and most likely also lung and breast cancer," she said. "If we confirm that what we've discovered in the mice studies also occurs in human cancers, we may soon be in a good position to slow this cancer process using drugs already under study ...

New cell type identified in cancer development

...a, but they have also been found in breast, brain, colon and prostate cancers. Because they are rather unstable, they are notoriously tricky to isolate and describe. They are also resistant to virtually any kind of treatment, and some scientists believe they are the reason cancer recurs. Until now, no one...

Arsenic in chicken feed may pose health risks to humans, C&EN reports

...has been linked to bladder, lung, skin, kidney and colon cancer, while low-level exposures can lead to partial paralysis and diabetes, the article notes. Use of roxarsone has become a topic of increasing controversy. A growing number of food suppliers have stopped using the compound, including the nati...

Need oxygen? Cells know how to spend and save

...in hypoxia. In low oxygen, liver, uterus, lung and colon cells all made COX4-2. The researchers then exposed mice to hypoxia for a few weeks and found that they too showed increased levels of COX4-2. In 1992, Semenza's team had discovered a protein which they called HIF-1 (for hypoxia-inducible factor ...

Gut research yields new anti-cancer approach

... author of the paper. "Because cells that line the colon are similar to those in the liver, esophagus and skin, we see potential for a new way to treat those cancers as well." In the study that led to the discovery of the anti-cancer effect, researchers were looking for new ways to reduce inflammation s...

Dealing deadly cancers a knockout punch

... in April, 2007. In mice transplanted with a human colon cancer, Reolysin plus gemcitabine completely eradicated the tumors in four of five test animals. It is rare to see the virtual elimination of tumours as well as the long-lasting therapeutic effect that was observed in this study. "Combination the...

Targeting sugar on blood vessels may inhibit cancer growth

"If novel drugs can be developed to target tumor heparan sulfate, we might be able to make a leap in cancer-fighting therapies, because several molecules critical to tumor endothelial growth also bind to heparan sulfate," Fuster ...

U-M researchers discover gene switched off in cancer can be turned on

...ing cells from lung, esophageal, ovarian, bladder, colon and breast cancers. The researchers were able to use existing drugs, which showed some usefulness in turning on the BRM gene. But new drugs would need to be developed to be more effective in reactivating this gene in cancer cells. Still, researche...
