- Had grown into the surrounding healthy tissue (invasive breast cancer)
- Has been removed with surgery
And you are in one of the following situations:
- 1 to 9 lymph nodes under your arm have cancer in them. If your cancer has spread to only 1 to 3 lymph nodes, at least in 1 node the spread is greater than 2mm across
- Your cancer measured more than 20mm, it has spread to 1 to 3 lymph nodes and is less than 2mm across in each node
- Your cancer measured 30mm or more but had not spread to the lymph nodes
And all of the following apply:
- Your cancer is oestrogen receptor positive
- Your cancer is HER 2 negative
- You are able to have chemotherapy after your surgery
