Potential link between breast cancer genes, salivary gland cancer

Potential link between breast cancer genes, salivary gland cancer

The risk of developing cancer in a salivary gland might be higher in people with mutations in either of two genes associated with breast and ovarian cancer, according to a new study by researchers at The Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC — James) Continue reading

Survival molecule helps cancer cells hide from the immune system

Survival molecule helps cancer cells hide from the immune system

A molecule that helps cancer cells evade programmed self-destruction, an internal source of death, might also help malignant cells hide from the immune system, an external source of death. A new study by researchers at The Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J Continue reading

New at-risk group identified for gastrointestinal stromal tumors

New at-risk group identified for gastrointestinal stromal tumors

Researchers at the University of California, San Diego School of Medicine have, for the first time, clearly defined the epidemiology of gastrointestinal stromal tumors (GIST), which occur primarily in the lining of the stomach and small intestine. One key finding: Patients of Asian descent, who have not previously been identified as an at-risk population, are 1.5 times more likely than other patient groups to be diagnosed with this type of tumor. Results of the study were published this week in Cancer Epidemiology, Biomarkers & Prevention , a journal of the American Association for Cancer Research. Continue reading

New ‘lab-on-a-chip’ could revolutionize early diagnosis of cancer

New ‘lab-on-a-chip’ could revolutionize early diagnosis of cancer

Scientists have been laboring to detect cancer and a host of other diseases in people using promising new biomarkers called “exosomes.” Indeed, Popular Science magazine named exosome-based cancer diagnostics one of the 20 breakthroughs that will shape the world this year. Exosomes could lead to less invasive, earlier detection of cancer, and sharply boost patients’ odds of survival Continue reading

‘Cyberwar’ against cancer gets a boost from intelligent nanocarriers

‘Cyberwar’ against cancer gets a boost from intelligent nanocarriers

Two years ago, Prof. Eshel Ben-Jacob of Tel Aviv University’s School of Physics and Astronomy and Rice University’s Center for Theoretical Biological Physics made the startling discovery that cancer, like an enemy hacker in cyberspace, targets the body’s communication network to inflict widespread damage on the entire system.

A diet for the cell: Keeping DNA fit with fewer calories

A diet for the cell: Keeping DNA fit with fewer calories

Cells are generally able to repair spontaneous damage that arises in their genetic material. Unfortunately, the DNA repair process is not perfect and sometimes, damaged DNA gets passed on to newly made cells Continue reading

One in three people with cancer has anxiety or other mental health challenges

One in three people with cancer has anxiety or other mental health challenges

Researchers in Germany report that nearly a third of more than 2,100 patients with cancer interviewed at inpatient and outpatient care centers experienced a clinically meaningful level of mental or emotional distress that meets the strict diagnostic criteria for mental disorders including anxiety, depressive and adjustment disorders during the prior four weeks.

Cancer medicine: New, improved, expensive and exploited?

Cancer medicine: New, improved, expensive and exploited?

Two studies published in the October 2014 issue of Health Affairs by a University of Chicago health economist examine spending on oral anti-cancer drugs as well as a federal program designed to help the poor, which researchers say instead helps hospitals boost profits. The first study, by Rena M. Continue reading

Cell migration: How it works, how new discovery may inform cancer research

Cell migration: How it works, how new discovery may inform cancer research

During cancer metastasis, immune response cells are moving in a controlled manner through the body. Researchers from the Department of Biomedicine at the University of Basel discovered novel mechanisms of cell migration by observing cells moving on lines of connective tissue. Their results, published in the journal Developmental Cell, could lead to new approaches in combatting cancer metastasis and inflammation Continue reading

Tumors might grow faster at night

Tumors might grow faster at night

They emerge at night, while we sleep unaware, growing and spreading out as quickly as they can. And they are deadly. Continue reading
