My Mom (age 68) was diagnosed with TNBC in Dec 2018 at forits under Dr. Boman. Went 4 weekly cycle of paclitaxel and 2 ZA. Due to severe side-effects, had to stop chemo. In April docs at TMC said this is CUPS (cancer of unknown primary) and denied the TNBC. My Questions are:
1. How come TNBC can convert to CUPS in 4 months?
2. What are the best treatments options for CUPS? My mom has metastasis in bones and pain especially in pelvis region. Also got 5 radiations in ribs 5 and 7 at TMC. Now pain in ribs are gone. but pain in the pelvis region continues.
