BiRads 5

Hello everyone. I am new here and am looking for some guidance and support. I had a mammogram yesterday where they found a lump in my right breast. After the mammogram, they did an ultrasound confirming what they had found. The report states that I am BiRads 5. Everything that I am reading online is telling me that I very likely have cancer. The odds of not having it are very slim right? My biopsy isn't until Tuesday of next week so I have a little while to wait while the results come back. If there are any positive stories out there of BiRads 5 that you think would be helpful, please share!
