Hi @Halza, I'm not sure why your surgeon would necessarily suggest 2yrs before you can have reconstruction, unless, as the others have suggested, it is due to the waiting list if you are in the public system.
I did have a delayed DIEP (where they use stomach fat to make a breast) reconstruction, and as it turned out it was a 2yr break between my mastectomy and reconstruction, but that was my choice. The reason I waited was that I wanted to get through all the treatments (chemo, Herceptin and radiation), feel confident that things were stable in relation to the cancer and to fully heal before undergoing reconstruction as the chemo and radiation were pretty hard going. I could, however, have chosen to proceed with the reconstruction a bit earlier as I went through the private health system. I did have my name on the public hospital waiting list (at Prince of Wales in Sydney) but it was at least a 2-3yr wait and I couldn't be sure that I would have the surgeon of my choice.
There are some options to talk to your surgeon about, including the possibility as @primek suggested, of an "immediate delayed" reconstruction where the breast surgeon places a tissue expander at the same time as your mastectomy. The tissue expander can help prepare the area for later reconstruction (including DIEP).
DIEP is usually the reconstruction option many surgeons recommend if you are having radiation as there is a higher possibility of complications and failures with implants after radiation, although it does largely depend on how well your skin and the underlying areas are affected. You might find this page useful on the Reclaim Your Curves website which talks about immediate vs delayed reconstruction:
https://www.reclaimyourcurves.org.au/timing-of-breast-reconstruction.html. There is further information on that website about most of the reconstruction options available in Australia and hopefully you will join us in the Choosing Breast Reconstruction group on this site as there are a wealth of photo stories and wonderful members who are able to share their experiences around reconstruction with you.
Hope this helps. Jane xx
