A new paper in PNAS is the third published recently by a group at the Australian National University (ANU). The group has collaborated with scientists from around the globe to uncover potential ammunition in the fight against malaria. Over 200 million people contract malaria each year, and the parasite that causes the disease has become resistant to most of the drugs currently available…
Computed Tomography (CT) screening can identify lung tumors while they are still treatable, and the US National Lung Screening Trial (NLST) found that annual screening of high-risk smokers can reduce lung cancer mortality by 20%. The best way to identify those at high risk remains an important question. …
The research was led by Dr Alex J Mitchell, consultant psychiatrist in the Department of Cancer Studies, University of Leicester. Studies have previously shown there is a higher mortality rate due to cancer in people with mental illness, perhaps because of high rates of risk factors such as smoking…
Breasts are considered dense if they have a lot of fibrous or glandular tissue but not much fatty tissue. Research has shown that dense breasts are more likely to develop cancer, a problem compounded by the fact that cancer in dense breasts can be difficult to detect on mammograms. Other imaging modalities like ultrasound and MRI are often used to help find cancers that can’t be seen on mammograms, but both modalities have higher rates of false-positive findings, which are suspicious findings that turn out not to be cancer. This higher false-positive rate often results in more tests and unnecessary biopsies, making MRI and ultrasound expensive to implement in high-volume screening programs, according to study lead author Per Skaane, M.D., Ph.D., from the Department of Radiology at Oslo University Hospital in Oslo, Norway. …
“Screening recommendations for this age group continue to be debated,” said Bonnie N. Joe, M.D., Ph.D., associate professor in residence and chief of women’s imaging at University of California, San Francisco (UCSF)…
Reflux can be a common side effect of chemotherapy or radiation treatment for head and neck cancer. Doctors at the University of Michigan frequently prescribe two types of antacids – proton pump inhibitors or histamine 2 blockers – to help treat this side effect. The researchers looked at 596 patients who were treated for head and neck cancer…
Gorlin syndrome causes an increased risk of developing cancers of the skin and, rarely, in the brain. …

More than half (53 per cent) of 1,700 people who completed a health questionnaire said they had experienced at least one red-flag cancer ‘alarm’ symptom during the previous three months. But only two per cent of them thought that cancer was a possible cause…
