Hi there
Everyone is different so it’s hard to say if what one person had is what you will be recommended.
Did you mean stage 3 rather than grade 3?
Stage 3 means it’s in the lymph nodes and it does seem to be that most ladies who are stage 3 are recommended chemo.
Grade 3 is the aggressiveness of the cancer , again this grade would more likely than not mean chemo.
I see you are in Newcastle so you should have access to a very good medical team there so as hard as it is you will probably just have to wait like they say.
You may want to get your hair cut short for summer anyway and then you will be ready if needed.
I didn’t have chemo so can’t comment on the cold cap but many ladies have successfully saved their hair using it although it doesn’t always work.
Do you have a breast care nurse - they are great for questions like this.
Take care🌺
