8/14/2018What does it mean an ill-defined centrally located tumor measuring 1.8x1.5x.09 cm. Is 1.8 the actual size of the tumor and does ill-defined mean what it says - ie a description vs the actual state of the tumor.

- IDC and DCIS present. DCIS positive for EIC- what does this mean? Also, had the oncotype DX test done. Node negative and score of 3- is this normal?

_Will make a donation to the foundation to support the great work you all do- thanks a million for your prompt response. Do I get a receipt for tax purposes?

8/14/20181.8 cm is the largest of the 3 dimensions of this lesion. Ill-defined means that the edges of the tumor did not have defined borders. Extensive intraductal component (EIC) in breast imaging evaluation is the pathological description where an invasive ductal carcinoma has a prominent intraductal component within it or if there is intraductal carcinoma, DCIS is present within sections of normal adjacent tissue. An Oncotype score of 3 is very low, meaning there is a low risk for recurrence.
