Researchers at the John Hopkins University in Baltimore have announced that they are close to (DEVELOP) a new blood test that could detect common cancer forms.

The new test, called CancerSEEK , would cost about $500 and be able to identify early forms of cancer cells in the body. According to the (SCIENCE) working on the project, the test concentrates on the most frequent types of cancers including lung, breast, colon, and stomach cancer.

After examining about 1000 people diagnosed with these cancer forms, the new blood test found signs of cancer in 70% of them. Tumours release tiny amounts of altered DNA into the bloodstream. The test looks for (MUTATE) in 16 genes that (FREQUENT) appear in cancer.

Although the first tests have had (PROMISE) results there are problems that have to be dealt with. There is still a high rate of false alarms, where cancer is shown in patients who are not diagnosed with any disease. Another problem is that the test sometimes shows signs of cancer but cannot find its exact (LOCATE).

Doctors state that the new blood test could be a major breakthrough for cancer patients and can extend their lives. The (EARLY) a cancer is found and located the better the chances are for it to be (TREAT).

The ultimate goal is to find cancer at early stages of the (ILL) , at a time when patients can be treated (SUCCESS). In some forms of cancer, for example, pancreatic cancer, symptoms show up in the late stages of the disease. As a result, four out of five patients die (SHORT) after it has been diagnosed.
