This sounds very promising. According to an article on CBC Canada, researchers in Albert have developed a new and better way of detecting cancer:

A faster, cheaper cancer diagnosis technology called a "fish on a chip" has been developed in Alberta.

The diagnostic chip miniaturizes and automates testing for chromosome mutations from many types of cancer, shortening the wait for diagnosis.

The article goes on to explain:

The FISH technology, short for fluorescent in situ hybridization, attaches coloured dyes to detect mutations such as breaks and reattachments in chromosomes.

The test maps the DNA in a blood or bone marrow sample to tell doctors what type of cancer they're dealing with, and provides information on how to treat it.

Physorg.com has this to say:

FISH on a chip will allow widespread use of the tests because of its higher speed and lower costs. The rapid detection of chromosomal mutations will significantly increase a physician's ability to tailor treatment strategies to target individual cancers.
