Recovery time after mastectomy depends on the type of breast reconstruction you undergo, and can vary by the patient depending on the overall status of your health and whether you've undergone a bilateral or unilateral mastectomy. For patients who have had a tissue expander placed or who have done a direct-to-implant reconstruction following mastectomy, I typically recommend 4 weeks off work. If your job is very physically demanding, then 6 weeks may be more appropriate. For patients who have undergone a living tissue reconstruction, such as a DIEP flap reconstruction, I also recommend 4 weeks off work. For older patients, those with higher BMIs, or those with a poor overall health status, 6 weeks is definitely more appropriate. For those with physically demanding jobs, such as nurses, childcare workers, gym instructors, or policewomen, up to 8 weeks off work may be appropriate.
