Does DCIS come back after mastectomy?
A mastectomy will almost certainly cure ductal carcinoma in situ (DCIS). DCIS is when the cancer cells are completely contained within the inner lining of the breast ducts. In this situation, when doctors remove the breast they are very likely to remove all the cancer cells. But in rare cases, DCIS or cancer can come back after mastectomy because it is not possible to remove all of the breast tissue.
If a mastectomy is needed you can have breast reconstruction at the same time or some time afterwards to create a new breast.
Often though, a mastectomy is not necessary for DCIS. For some women, it can be just as effective to remove the area of DCIS with a border of healthy tissue around it. The surgery is often followed by radiotherapy or hormone therapy or both.
The type of surgery most appropriate for you will depend on the size of the area of DCIS, and whether there is more than one area. Your surgeon will be able to tell you what your treatment options are.
Trials are being carried out to find the best treatments for DCIS, taking into account the size and grade of the DCIS cells.
