A Step Closer to a Simple Blood Test That Can Detect Cancer

 blood test

Blood test will be able to detect one cancer cell among a billion healthy cells.

A blood test so sensitive it can spot a single cancer cell lurking among a billion healthy ones is moving a step closer to being available at your doctor’s office, with potentially revolutionary medical implications.

 

Implantable Cancer Vaccine First To Eliminate Tumors In Mice

implantbased

A polymer implant, 8.5 mm in diameter, is embedded with chemical signals that encourage immune cells to attack tumors.

A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week in the journal Science Translational Medicine.

Research Shows How Cancer Spreads To Brain

Research Shows How Cancer Spreads To Brain

Breast cancer cells (in green) grow only on blood vessels (red) in the brain of a mouse. 

Research has shown for the first time how cancers that spread to the brain establish themselves and begin to grow.

The Oxford University study, published in the journal PLoS One, has identified the mechanism that metastatic cancer cells use to anchor themselves to blood vessels in the brain. This could allow new drugs to be developed to stop cancers from spreading and growing in the brain.

FDA Approves First Canine Cancer Drug

FDA Approves First Canine Cancer Drug

FDA approves first drug for canine cancer

The Food and Drug Administration approved today the nation’s first drug developed specifically for the treatment of canine cancer.

Manufactured by Pfizer Animal Health Inc., based in New York City, the drug marketed as Palladia, or chemically known as toceranib phosphate, will hit the markets in early 2010.

Why Are A Majority Of People Resistant To Cancer?

Why Are A Majority Of People Resistant To Cancer? 

 Dividing cancer cells

Every year, millions of people are diagnosed with cancer – a remarkably high number. But what about the flipside of those statistics? That is, two out of three people never get cancer, and more than half of heavy smokers don’t get cancer, either. A recent study points out this overlooked fact, and suggests that researchers might discover something by asking why so many people are resistant to the often deadly disease.

Surgical Imaging System Turns Cancer Cells Neon

Surgical Imaging System Turns Cancer Cells Neon 

A real-time surgical imaging system (top) displays live video.  Image produced by the new system (bottom) shows a pig’s hind leg after injection of a contrast agent.  

Many cancer patients leave surgery still harboring dangerous tumor cells, while others suffer painful aftereffects because a surgeon has removed too much healthy tissue or nicked a nerve. A new imaging system that highlights cancerous tissue in lurid colors should help surgeons remove every last trace of cancer without harming the surrounding tissue. The system, currently in early clinical trials, uses a new class of contrast agents that emit near-infrared light and can attach to virtually any kind of tissue, cancerous or a healthy–showing surgeons just where to cut.

Extreme Surgery

Dr Tomoaki Kato had to remove a lot more than a cancerous tumor during an unprecedented operation on a 63-year-old Florida woman earlier this month.

To get to the tumor, which was buried deep in Brooke Zepp’s abdomen and threatened to kill her within months, the organ transplant specialist said he first had to remove her stomach, pancreas, spleen, liver and small and large intestines.
