12 cm tumor with no lymph node involvment

Dr said this is an odd case. To have a tumor that is an ulcerated and fungating invasive DC that is 13.5 x 10 x 6.4 cm, and no lymph node involvement, and also no vascular invasion is unheard of. Is this something that i should have retested by another Dr.? I am also triple neg. Here is my pathology report. Just think it is quite odd to have such an aggressive Large cancer no invading nodes or vessels.

13.5x10x6.4 cm idc ulcerated and fungating invasive ductal carcinoma. With invasion into the deep skeletal muscle focally extending to the deep inked margin of resection. 12 lymph nodes negative for metastatic carcinoma.

the mass grossly appears to invade the aforementioned skeletal mucsle and come within less than 1mm of the margin of resection. the mass is contiguous with the aforementioned area of exophytic tumor extention of the anterior skin surface and comews within 0.5 cm of the margin. the mass grossly appears to involve all 4 quadrants of the breast. residual fibrofatty breast parenchyma is present predominantly along the superior aspect of the specimen with a scant amount along the medial and lateral aspects.
