Why a Duct? Because it's Duct Carcinoma in Situ

Well, that title does not make sense, unless you've seen Marx Brothers films. So, the vast majority of the Earth's population, will now say Huh?
Anyway, I have cancer Number 2. in another breast. (Would I have infinite amount of cancers for infinite amounts of breasts? What if I were a pig or dog? That's a lot of cancers).
Cancer number 2 is duct cancer in situ, stage 0, bordering on 1. In situ, latin for in place, means, it's in a milk duct and not moving or spreading. Just sitting. Small and hard, calcified, 2 centimeters of cancer.
Kind of creepy to have some tiny malignancy, just sitting in a alleyway of one's breast.
The thought is to have radiation and have no cancer by Summer.
That's the plan.
