Yes. It is called the Onco Type DX Test. The cost is $3,000 but insurance often covers it. The company checks with your insurance company and will discuss it with you before they do the test. If a family earns less than $70,000 a year, they give a big discount if insurance doesn't cover it. It is used for early stage breast cancer which is node negative. They send a sample of your tumor to a lab in California. They use the sample to check the how receptive it is to estrogen, progesterone, and Her2. They rate the chances of cancer returning in 10 years. The rating is either low, intermediate, or high. They specify that even a high rating does not mean it will definately return. They also say that if it returns it does not necessarily change the prognosis. Those who have a low rating will not benefit significantly from chemo and it is not generally used on them. Those like myself who are intermediate have a decision to make because there isn't a clear cut decision. In my case, the likelyhood or my cancer returning in 10 years is 15%. Chemo would reduce that by 3%. I decided not to have the chemo. I am 58 years old and at my age I was concerned that I would have more trouble than a younger woman would at recovering from chemo with not much return. I have made lifestyle changes which I hope will impove my results as much as chemo but who knows.
I strongly recommend this test if you are early Stage 1 or 2 and are node negative. My surgeon ordered it for me so I recommend you start there.
Good luck.
