Timing of Reconstruction

- Always immediate

- Delayed only if:

- Locally advanced disease

- Concomitant diseasesA.Luini

SSM + immediate reconstruction with prosthesis or expander is nowadays the standard treatment, except for:- Inflammatory cancer- Locally advanced disease- Poor general conditions
