By NBC News
Scientists are getting closer to a blood test to detect as many as eight different types of cancer. The test from Johns Hopkins researchers is called "cancer-seek." Scientists say the blood test has the potential to screen for a variety of cancers. Early research indicates the test may be able to pick up on tumors long before patients show symptoms. Scientists say the blood test could cost less than $500.
