I was diagnosed with mixed ductal and lobular breast cancer in Oct 24 stage 1 grade 2…. I have had 4 operations in total to get clear margins due to DCIS, one tumor was 18mm and the other 6mm…. I was informed via NHS that I would just need radiotherapy and tamoxifen as my cancer was ER positive, HER2 negative. I couldn’t get clear margins on the NHS so I had a reduction in both breast privately…. The oncologist I was referred to private reviewed my original histology report and noted KI-67 was at 50% which they deemed high so they requested an oncotype DX test that came back at 17 which is in the low risk bracket with a 5% reduction of cancer returning should I have chemo…. I am 46 and perimenopausal…… they have offered me chemo and I am unsure if to do it, the side effects don’t seem favourable with a 5% gain… what is everyone else’s thoughts or has anyone been in this situation
Hi Amanda79. Have you had a sentinel node biopsy and were any lymph nodes affected? I am asking as lobular breast cancer has a higher rate of reoccurrence than DCIS. You have a hard choice to make. I had lobular breast cancer aged 47 and one lymph node affected I had chemo, radiotherapy etc was not given a choice. I wish you well in your choice. I am here if you wish to chat.

Hi Amanda79 I found the chemo tough. I hated losing my hair, it was very long before cancer. It has grown back now though. Chemo is hard but it is doable. Cancer is so very unpredictable you never know what it is going to do or if it will come back. My Mom had breast cancer and said it is like living with a time bomb and I sort of know what she meant now. I really do wish you well in your very difficult decision.

Hi
I'm currently having chemotherapy for breast cancer, I have a different type of breast cancer to you and I decided that because it can reduce my personal risk of my cancer coming back by 70% - 80% i should do it, as statistically it's a no brainer.
However, I personally would not put myself through chemotherapy for a 5% gain, knowing how bad chemotherapy is.
Speak to your consultant to find out all your options, there could be other alternatives to explore for you.
Hope this helps
Hi Amanda
I've got similar to you, my percentage was 5.6% and there was no choice whether to chemo or not chemo. I'm staring mine next week, all the preparation in place now.
It's a horrible horrible thing to go through, but you have to think of future. You are still young and that's why they would recommend you do it, because you will tolerate the chemo better than someone older, let's say.
By offering chemo to you, they are trying to make sure all cancer is killed off and less likely to come back and then you have to go through it all again.
The scans can only detect cancer over 6mm big, anything smaller than that, scans will not pick up. They could be anywhere in your body. If they found any cancer in your lymph nodes then it would definitely be worth the the pain to go through it. Chemo will make sure all these micro cells are killed off .
Did they tell you how long course if chemo you would be taking? Maybe it will be a short course and it'll be over in a jiffy. I originally thought I'll be getting radiotherapy and hormone therapy but the reoccurrence % then decided I need chemo too. Mine is 20 weeks, and not looking forward to it at all!!!! But im thinking of my kids and the future.
Hope this helps to make your mind up and wish you good luck! ️
Thank you is really does… they mentioned hormone therapy as another option
