So I was looking at my path report again and saw this "Ductal carcinoma in situ (DCIS): present <5%." I'm sure this means low amount but at what point do you put it down as something found---or is this so small it doesn't matter? I guess I"m not sure what this is. Anyone know? Tia

    Frequently DCIS will be found in conjunction with other sorts of BC. Generally, while it should be removed, treatments are dictated by the other BC types.

    So (at this point) it's almost a "due diligence" comment by the pathologist (showing that they're telling you everything they saw/identified in the pathology samples they examined).

    You never know, however, what future research into BC types may indicate. Maybe at some point in the future it will be important to know that you had a small DCIS component too? Who knows...

    HTH,

    Artista, LisaAlissa is correct. It is very common for some DCIS to be present with a later stage cancer diagnosis (by later, I mean later than Stage 0 which is what DCIS is) because often the tumor started out in the duct as DCIS and grew outward to become an IDC so the original has not all broken out of the duct and remains DCIS. It is thought that around 80-90% of all IDC starts out as DCIS but was not picked up prior to it morphing that extra step that makes it invasive into the breast. So, with that said, quite a common occurrence.

    Your treatment is always based on the more serious of your breast cancer which in your case was your IDC. All your treatment should have taken care of your tiny DCIS that was identified in pathology. Hope this helps.
