Can inflammatory breast cancer get worse and better?

Depends on stage: It is an aggressive disease. There is no stages 1 or 2. It is either stage 3 or 4 at diagnosis. For stage 3, chemotherapy is usually given first, follwed by surgery, then radiation therapy. Hormonal therapy if er+. Yes, patients may be cured with proper treatment, but many do have recurrence. For stage 4, patients may do well on chemo initially but in all the cancer will progress eventually.
