Yes, I just did a quick search and oncotype is used on DCIS. You might have to ask for it.
I am sorry that some folks get blindsided by these tests, and they certainly should have been better prepared, but the ultimate decisions on treatment are still a cost vs. benefit decision between each of us and our doctors.
A test does not make all the decisions for you, but a great doctor who saved my life once said to me “the only good decision is an informed decision”. I wish this test were available when I was first diagnosed. Then at least I could have understood more about MY cancer. I feel more in control of the decision making process when I have more information.
Are you considering having this test?
