In February 2018 I was diagnosed with Stage 4 Breast cancer that has metastasized to my bones. They found the cancer in the bone after 1 1/2 years of appointments and misdiagnosis. After the biopsy in my hip they then had to go search my breast for the original cancer. It was not detected on a mammogram. Started Ibrance and Letrozole. It knocked my neutrophils to 0.3 and I had to wait 3 weeks to start my second month. This is all new and frightening to me.
