I just had my first three months scan, after 3 cycles of ibrance and letrozole. The scan report says that there are numerous new and enlarging pulmonary nodes throughout the lungs. Newly enlarged right and left hilar lymph nodes. Also some concern for possible metastasis on The L4 vertebrae. It appears that things are progressing fast. I am so scared. If the ibrance and letrozole don't work what's next, chemo?
