Carcinoma left breast
The breast tumor showed necrotic tissue and open biopsy had to be performed to confirm an IDC. The node aspirate was positive for metastatic adenocarcinoma.
Fortunately cases like this are scarce these days.
Ultimately, all factors being equal, the outcome of breast cancer is related to the size of the tumor at the time of diagnosis. And currently the best way to screen is still mammography.
