New blood test that detects cancer developed in Israel
In first trial, researchers able to detect cancer in some 90% of patients. Professor: We're optimistic
Beersheba's Soroka Medical Center and Ben Gurion University are developing a unique method to detect various types of cancer through a simple blood test.
Researchers say that in a first trial conducted recently, they succeeded in detecting cancer in almost 90% of cancer patients tested.

"This is still a research in the early stages of clinical trials," clarifies Prof. Joseph Kapelushnik, head of the Pediatric Hemato-Oncology department at the hospital.
"But the purpose is to develop an efficient, cheap and simple method to detect as many types of cancers as possible."
Doctors say it is imperative to increase early detection of cancer in patients, before it gets to advanced stages that must be treated with a long and difficult treatment.
Scientists around the world are working to find new methods to detect cancer; artificial noses that can identify a certain substance in cancer; techniques for discovering cancer antibodies; mammography to detect breast cancer; colonoscopy and fecal occult blood testing to detect colorectal cancer, for example.
Prof. Kapelushnik and his research partners have developed a method that detects cancer with blood tests, using infrared light beams. The researchers take a small amount of blood and insert it into a device they developed. Using this device, a spectrum of infrared light is beamed through the blood, enabling the researchers to estimate whether the patient has cancer or not.
At this stage, the researchers are concentrating their efforts on the detection of common cancer types, such as lung cancer and ovarial cancer. Nevertheless, they also succeeded in detecting other cancers.
In the latest clinical trial, about 200 patients with various types of cancer were examined along with a control group.
"We succeeded to tell them apart with 90% accuracy," says Prof. Kapelushnik. "This is still a small number patients and we need thousands of people before we can say the new method actually works. In the meantime, though, we are optimistic about the results."
