Scientists Warn of Skin Cancer Risk From Airport Body Scanners

image Airport body scanners have a potentially greater risk of cancer than previously thought, a scientist has warned. The devices emit radiation up to 20 times more powerful than it was believed. Dr David Brenner, head of the centre for radiological research at Columbia University in New York, said that the concentration of the radiation on skin could pose a greater risk of cancer than expected. The risk is due to inability of a body to repair X-ray damage to its c...

Saliva Test can Help Detect Various Cancers

image Japanese and US universities have jointly developed a medical technique that can quickly detect various cancers using a simple saliva test, researchers said on Tuesday. Japan's Keio University and University of California, Los Angeles, have developed the technology with which they detected high probabilities of pancreatic cancer, breast cancer and oral cancer. The researchers analysed saliva samples of 215 people, including cancer patients, and identified 54 substances wh...

Number of Cancer Survivors Who Live With Their Minor Children, are More Than a Million

image More than a million cancer survivors live with their minor children, according to a first-ever estimate of cancer-survivors conducted by a team led by a Wake Forest University Baptist Medical Center researcher. Published early online today in ICancer/I, a peer-reviewed journal of the American Cancer Society, the study's results may help address the unmet needs of this unique group of patients and their families. "These families may undergo significant struggles and ha...

Bubbles may be Deployed to Destroy Cancer

image A research team from Leeds University has developed a method to destroy cancer by injecting gas bubbles into the bloodstream. The researchers used microbubbles to carry chemotherapy drugs to the site of the tumor. Such targeted therapy helps in better treatment of cancer. "By targeting the bubbles to the cancerous tissue, it means we can deliver far higher concentrations of drug to the tumour than is normally possible in chemotherapy," lead researcher Stephen Evans told The Te...

Study Says Fewer Than Half of Breast Cancer Patients Adhere to Hormonal Therapy Regimen

image Fewer than half of nearly 8,000 women with early-stage breast cancer completed their full regimen of hormone therapy according to the prescribed schedule, a new study has found. Investigators found that younger women were particularly likely to discontinue treatment. The findings underscore the need to both better understand the reasons behind such treatment non-compliance and also develop interventions to reduce it. "We were surprised to see that so many young women stop...

Path Breaking Method to Analyze Prostrate Cancer Developed

image The most comprehensive genomic analysis of prostate cancer has been developed by scientists who hope this will help to develop patient subgroups and in making individual treatment decisions. "One of the holy grails of prostate cancer is to identify which tumors need to be aggressively treated and which don't. Ultimately, what we have learned could lead to the creation of a genetic-based test to determine which prostate cancers might become more virulent and req...

Colon Cancer Screenings Increased by Automated Telephone Reminders

image A Kaiser Permanente Center for Health Research study funded by the National Cancer Institute that appears in the July print edition of IMedical Care/I, says that simple, automated telephone reminders can increase colon cancer screening rates by 30 percent. The study - which is the first to examine whether automated calls can increase screening for colon cancer - involved nearly 6,000 Kaiser Permanente members in Oregon and Washington who were overdue for screening. Half received...

Digital Camera can Spot Cancer Cells

image A rather inexpensive digital camera can help doctors easily distinguish cancerous cells from healthy cells by viewing the LCD montior on the back of the device. Rice University biomedical engineers and researchers from the University of Texas M.D. Anderson Cancer Center created the device. "Consumer-grade cameras can serve as powerful platforms for diagnostic imaging," Rice's Rebecca Richards-Kortum, the study's lead author, said. "Based on portability, perfo...

Novel Diagnostic Tool to Check for Bladder Cancer

image A new diagnostic tool for bladder cancer has been developed by researchers from the Danish Cancer Society and the Herlev University Hospital of Copenhagen. The related report by Serizawa et al, "Custom-designed MLPA using multiple short synthetic probes: application to methylation analysis of five promoter CpG islands in tumor and urine specimens from patients with bladder cancer," appears in the July 2010 issue of The IJournal of Molecular Diagnostics/I. Bladder cance...

Natural Substances Could Form the Basis of Cancer-preventing Medicines

image Scientists are working on medicines based on natural substances which may help prevent cancer. A new research has described how scientists, sifting through natural products from fruits and vegetables, have narrowed down the list to certain products such as resveratrol, a substance found in red wine. Other possible choices include abyssinone, a substance found in a plant from traditional Chinese medicine. Scientists are also studying potential cancer-preventin...
