Cancer After Neoadjuvant Chemotherapy: Is it Really Gone, Zip, Nada, Zilch?

[Inquiring Minds...]

With infiltrating ductal carcinoma, triple negative, does the agressiveness of the condition warrant an agressive treatment even if DR.'s state that the lesion (6.8 cm circumference) has totally dissapated and that the cancer is 'gone'? Pet/CT scans, MRI, and recent mamography all suggest that the cancerous lesion that I battled with this past Summer has now been resolved. My question, considering the agressiveness of the tumor, should I continue to be agressive in treatment, or as is an option, forgo a prophylactic intervention and immediate vs. delayed reconstruction in exchange for a breast-conserving surgery and a watchful eye every six months for possible recurrence?

Any thoughts?

I would like to assume that being
I take it that a cancerous lesion that large having 'disapeared' is a bit much for me to digest. It is much like the pouring of red wine into the fibers of an existing carpet: the stain can go as deep as the fibers, the padding and down to the floorboards themselves, thus the term 'infiltrating'... also with a cancer that large, radiation and further chemo treatments cannot be ruled out nor can possible SNB and/or axillary lymphnode dissection.
