Prevention Paying Off As Cancer Rate Drops

Iria — Tue, 25 Nov 2008 20:49:10 -0600

For the first time, an annual report by the American Cancer Society has shown that the rate at which Americans are getting cancer has declined for the first time.

Medical isotope supplies and nuclear medicine services

A global shortage of medical isotopes* used in over 80% of routine diagnostic nuclear imaging procedures such as heart imaging, bone scans and some cancer detection procedures, will cause delays and cancellations to diagnostic examinations across the UK and Europe in the next few weeks, predict experts on bmj.com today.

Developing New Tool to Detect Cancer

Early cancer detection can significantly improve survival rates. Current diagnostic tests often fail to detect cancer in the earliest stages and at the same time expose a patient to the harmful effects of radiation.

New biomarker for early cancer detection

Scientists at Fred Hutchinson Cancer Research Center have discovered that microRNAs – molecular workhorses that regulate gene expression – are released by cancer cells and circulate in the blood, which gives them the potential to become a new class of biomarkers to detect cancer at its earliest stages.

Medical check-ups for intestinal cancer are hardly used

Only 20% of persons aged over 55 use colonoscopies for early detection of cancer, even though the statutory health insurance funds have covered the costs since 2002. This was shown by an analysis of the Bavarian Colonoscopy Database published in the current edition of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2008; 105(24): 434-40).

Brown chemists create cancer-detecting nanoparticles

A team led by a Brown University chemist has created the smallest iron oxide nanoparticles to date for cancer detection by magnetic resonance imaging (MRI). The magnetic nanoparticles operate like tiny guided missiles, seeking and attaching themselves to malignant tumor cells. Once they bind, the particles emit stronger signals that MRI scans can detect.

OHSU discovery may lead to early cancer detection

OHSU pancreatic cancer expert Brett Sheppard, M.D., and colleagues in the OHSU Oregon Stem Cell Center, have developed antibodies that recognize pancreatic cancer; Sheppard is presenting these findings this week during Digestive Disease Week in San Diego

Cancer detected earlier, faster, with new medical imaging

Doctors may one day be able to detect early stages of colon cancer without a biopsy, using a new technique developed by researchers at the Stanford University School of Medicine.

Using laser light to detect potential diseases via breath samples

harminka — Tue, 19 Feb 2008 03:22:25 -0600

By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer.

Yale test detects early stage ovarian cancer with 99 percent accuracy

Researchers at Yale School of Medicine have developed a blood test with enough sensitivity and specificity to detect early stage ovarian cancer with 99 percent accuracy.

Gold nanoparticle probes may allow earlier cancer detection

harminka — Mon, 24 Dec 2007 01:54:10 -0600

Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasively

PET/CT imaging proves golden for detecting cancer in children

harminka — Thu, 13 Dec 2007 08:06:40 -0600

PET/CT imaging exhibits significantly higher sensitivity, specificity and accuracy than conventional imaging when it comes to detecting malignant tumors in children, according to research published in the December issue of the Journal of Nuclear Medicine.
