therapeutic mammoplasty for 'replacement' nipple?

I was diagnosed on Monday… invasive ductal stage 2, 25mm…
I am meeting the surgeon and his team (including plastic surgeon) on Friday - and hope to discuss surgery.
I am scheduled for a therapeutic mammoplasty (due to having large breasts (38E)) - so consider myself very lucky.
He has explained that I will loose 1/3rd of my left breast and the nipple as the tumor is under my nipple.
I have opted for immediate ‘reconstruction’ on my right to make it same size / shape.
What I dont understand is the options for the nipple, they did mention reconstruction, tattoo and something else I think…
Any advise would be greatly appreciated for the nipple and generally on therapeutic mammoplasty.
Many thanks
