The condition and the treatment(s)
Multiple myeloma is a type of cancer that affects cells in the bone marrow. Symptoms can include bone pain, bone fractures, anaemia, loss of appetite, excessive bleeding after cuts or scrapes, and frequent infections.
When given with drugs called bortezomib and dexamethasone, panobinostat helps to stop normal cells changing into cancer cells.
