In December of 2019, I was diagnosed with IDC i.e.invasive Ductal Carcinoma. 80% of breast cancers are this kind. I have not heard about anything called tubular unless you are saying that you will have a drainage tube; that comes with the surgery anyway (and there are other surgeries that have this, not just breast surgery). In thinking of all this, it is very overwhelming at first. Take one step at a time...Read about it so nothing comes as a shock. For me, I decided to see the big picture first...What is the safest way to go...i.e. Do you want to live? I felt that the best way to insure that the cancer could not spread (even though it was below Stage 1) was to have a complete mastectomy on my right breast plus the testing of the lymph nodes and I did. Yes, be careful to see that you have enough drainage going on...I was not a good candidate for reconstruction, per surgeon, due to other medical conditions and so I put that to rest. My mother also had a "radical" mastectomy as it was called in those days -(70's) done 53 years ago and she lived to be 90. I pray for you, find peace with it...
