Breast-conserving surgery and a mastectomy work equally well in treating early breast cancer. This means your surgeon and specialist nurse may ask you to decide which type of surgery you feel is right for you.
Your surgeon and specialist nurse can explain what is involved and any possible side effects of each treatment. They will help you decide on the treatment that is best for you.
It is helpful to think about the possible advantages and disadvantages of each type of surgery before making a decision.
- It aims to keep most of your breast tissue and a good breast shape.
- You may recover faster than with a mastectomy and have a lower risk of complications.
- It may be less likely to affect your sex life and relationships.
- You may not need radiotherapy after a mastectomy. But some women will need it. Ask your cancer doctor about this.
- You may feel less worried after the operation because the breast tissue has been removed.
- You lose your breast permanently.
- It may take longer to recover after a mastectomy, and there is a slightly higher risk of complications.
- It changes your appearance, which may affect your confidence, sex life and relationships.
- If you want breast reconstruction, you need a longer operation and possibly more surgery. But reconstruction may help to reduce some of the other disadvantages.
Your surgeon and specialist nurse can answer any questions you may have and tell you what to expect. They may be able to show you photographs of other women who have had surgery.
Talking to other people who have already had surgery can also help. Your specialist nurse may know whether there is a local cancer support group, where you can talk to someone who has had a similar operation.
Or you can visit our Online Community to talk to people who have been affected by breast cancer, share your experience, and ask an expert your questions.
