Hi everyone, I'm new here I've never posted before. I noticed that my right breast was a weird shape at the arc on the bottom just before Christmas but kind of ignored it and then just before new year I thought I should do a proper check on myself and I then noticed a dimple on the bottom and then a lump above it. I sent an online request for a same day doctors appointment on the Tuesday immediately after the New Year bank holiday. They text me an appointment time and saw me that morning. I was then referred on the 14 day system and was seen at the breast clinic on Thursday last week 12th Jan. 
Everything happened very quickly at the clinic the lead nurse saw me and she told me straight away she wasn't too happy and sent me down for the tests. I had an MRI type mammogram, an ultrasound and 2 core biopsies. I asked the radiographer if I had cancer and she said it was suspicious and to go back upstairs to have another chat with the first nurse that I saw. 
I went back up and the first thing I said is have I got cancer. She said in her opinion and that the imaging suggests that I do. She said that they had already checked my lymph nodes on the scan and it hasn't spread and that it is 2.1cm. She also said she thinks it is probably caught early and localised. She said that when the biopsy comes back they will know what it is and what stage and that my treatment plan will be in place when I go back in hopefully less than two weeks. I asked her if there was any chance that the biopsy might show that it's not and she said I should prepare myself that it is. Even though I had a sense myself hearing all this was a shock and I'm still trying to process it. I've already spoken to my closest friends and family as I'm single with a wonderful 17 year old son and we need to have that support.

I've got a couple of questions, has anyone else experienced this, is there any chance the biopsy could come back not cancer? 
We have a lot of cancer in the family and four years ago discovered we have the Lynch Syndrome genetic mutation on gene MLH1. I was tested for MLH1 four years ago and the test was negative. My mum was tested a few months after me and she was also negative. The nurse wants me to bring the paperwork in for this when I go back as she wants to know what was done. I'm now reading that there are five genetic mutations for Lynch. Is it possible to have more than one mutation in a family?

I have to say that all the medical staff were absolutely amazing and although i'm still reeling i'm glad that I already have this information so I am prepared for the results. Also just to say i'm 49. My cousin who has Lynch was diagnosed with cancer at 47, my aunt at my age and a cousin of my mum's also same age. My cousin (male) has Lynch but we don't know about my aunt and my mum's cousin as they both died before tumour testing for genetics. None of them had breast cancer. However my grandmother did and my grandfather had lung cancer. Also, I have been on HRT for two years, my GP took me off it two weeks ago at that first doctors appointment. I'm now really worried that the cancer is going to be oestrogen or progesterone fed and that I made a really bad decision. 

Thank you for reading any information would be very gratefully received X
