Hello Mandy,and welcome to BCNA online network.On the 2nd ofSeptember,I was diagnosed with invasive ductal carcinoma also.Mine was 17mm,and thankfully hadn't spread.It was classified as a grade 2 tumour.I was absolutely petrified,and turned to the ladies on here for support.I had never been sick a day in my life until this.On the 17th of Sep I had a mastectomy,which was nowhere near as bad as you would think,and then 4 weeks after my surgery I started my chemo. I am about halfway through,and I am going ok:)The best advice I can give you is to try and stay busy,and look to the ladies on here who have been there and done it before!The positive is that your tumour is under 2mm,and that the ultrasound suggests it is localised.Mine was the same.When I have finished my chemo,I will be going on to have Hormonal therapy for 5 years,as my cancer is estrogen and progesterone positive.It is normal to be scared,but over the next few days,and after you have met with your surgeon,you will have a plan put together,and then you will see that you will start to feel more in control and less terrified.Keep blogging on here Mandy,and there will be lots of other ladies that will come on and support you also.You will get through this.xoxoxSending you hugs.Robyn:)
