My sister was diagnosed with high grade ductal carcinoma in-situ, and invasive carcinoma stage 2 in January 2014 shortly after her mammogram showed something suspicious and she had a biopsy. She had a previous mammogram in August 2012 which was normal. However, the January 2014 mammogram said a particular area of micro-calcifications grew from what was seen in the August 2012 film when compared. Can DCIS turn into invasive cancer that quickly? It was a year and five months between the mammograms.
Hi, DCI doesn't usually appear as a breast lump or breast change. In some cases, however, low or intermediate grades of DCI can develop into invasive breast cancer. While the size and grade of DCI can help doctors predict whether the cancer is likely to become invasive, there are no certain answers. Hope I have answered your query. Let me know if I can assist you further.
