Stage 2B Patient
This is truly a question for your oncologist. However, it ALWAYS depends on your type of cancer how treatment is done. Please ask if you can have the oncotype dx text done, it is very expensive, but most insurances cover a good deal, and if you made less than $125,000 income, you might be getting the testing done for free. Visit the oncotype dx website and you can learn more about it.
But again, ask your team. Good luck.
