We all look forward to the day when a simple medical test can find cancer while it is still small. Researchers around the world are working on such a test. Most of their work deals with the examination of the blood.

　　Researchers in Boston have found something in the blood of cancer patients that does not appear in healthy persons. The test showed which persons had cancer and which did not. It was correct more than 90 percent of the time.

　　The researchers believe the test may be able to show cancer very clearly in its development. Cancers discovered early usually can be treated successfully.

　　The test examines very small bits of fat in the blood called lipids (脂质). Cancers seem to change lipids although doctors do not know why. The test showed differences between the lipids of the persons with cancer and the lipids of those without cancer.

　　The researchers say the new test could be a step to develop a simple way to check patients for cancer before the disease shows on an X-ray.
