Hello @everything it sounds like you are having a time. Most of us have been there and understand the tons of questions without really knowing what to ask. Ductal carcinoma is the type of breast cancer that starts in the milk duct. You should get a stage based on size of tumor and the lymphovascular involvement. There will likely be, some more testing to help determine a treatment plan. Do you have someone who can go with you to see the oncologist, there will be a lot of information coming at you, and a second set of ears can be really helpful.
How are you holding up? Have you started working on a list of questions yet?
