So why go to a cancer center for your treatment? Why is it so important? Do you want someone to treat you who treats one case pf breast cancer a month or someone who treats dozens of cases each month?
There can be little bitty differences in tests, biopsies, side effects and a lot of other things that may not be significant to a doctor who sees them as being in the normal range but to a specialist as a group they may provide an indicator of something else.
This video actually does a really good job of explaining the importance of going to a specialist and a cancer center.
It is also true of going to specialists for a lot of different medical issues. It might even justify all the specialists I see - medical oncologist, radiation oncologist, breast surgeon, endocrinologist, rhematologist - that I see regularly in addition to my primary care and my therapists.
