Key points
- 1
A mastectomy is surgery to remove all of the breast tissue, most commonly performed as part of breast cancer treatment, though it can also be done as a preventive measure for people at very high genetic risk. Depending on individual circumstances, breast reconstruction can be performed at the same time as the mastectomy or at a later date, or some people choose not to have reconstruction.

01 · Know
What is Mastectomy?
A mastectomy is surgery to remove all of the breast tissue, most commonly performed as part of breast cancer treatment, though it can also be done as a preventive measure for people at very high genetic risk. Depending on individual circumstances, breast reconstruction can be performed at the same time as the mastectomy or at a later date, or some people choose not to have reconstruction.
Recovery involves physical healing over several weeks, alongside what can be a significant emotional adjustment. Support is available for both the physical and emotional aspects of this experience, and there's no single "right" choice about reconstruction — this is a personal decision.
02 · Understand
Clinical context
Reconstruction decisions can often be made over time, not all at once
While some people choose immediate reconstruction during the same surgery, delayed reconstruction is also an option, allowing more time to consider the choice without added pressure during an already significant time.

Practical steps
There's No Single Right Choice About Reconstruction
Whether to have reconstruction, and when, is a deeply personal decision — there's no universally "right" answer, and taking the time you need to decide, without pressure, is entirely reasonable.
- 1Follow post-surgical wound care instructions closely.This supports proper healing in the weeks after surgery.
- 2Attend physiotherapy if recommended.This can help with shoulder and arm movement, particularly if lymph nodes were also removed.
- 3Take time to consider reconstruction options.This can be discussed before surgery or afterward, whenever feels right for you.
- 4Seek support for the emotional impact.Counselling and support groups can help process the emotional aspects of mastectomy alongside physical recovery.
- 5Attend all follow-up appointments.These monitor your recovery and ongoing cancer care.
