Breast cancer explanation

Hi, I'm after some help please concerning a letter that my mum has received. She has been diagnosed with breast cancer. She is due to have a scan next week but the latest correspondence states she has ' grade 2 invasive carcinoma mixed with lobular features plus DCIS and LCIS ER8 PR7 Ki-67 10 HER negative'. I have no idea what all this means. Is there anyone who could explain? I understand that grade 2 relates to the cells but what do all the other letters and numbers mean?

Thank you for reading!

    Hi I’m sorry to hear about your mum.

    have a look at Breast Cancer Now website

    DCIS ductal carcinoma in situ 

    LCIS lobular carcinoma in situ

    ER is oestrogen and PR is progesterone , both positive 80% of breast cancers are oestrogen positive .

    HER is the extra oestrogen receptor test , that’s negative . 

    KI67 is the marker that tells you how quickly the cells are dividing . I think that’s 10% ?

    I have lobular breast cancer which is ER\PR + HER -. I find have my ki score yet but it’s grade 2.

    can your mum speak to her breast cancer nurse ?
