Sir my fiance have a blood cancer at third stage what should we do to finish it. with chemothrapy or other one process what will better for her . ?

Blood cancer: I can give you a more detailed input but you need to share the details about what type of blood cancer she has, what tests have been done. What treatment has been recommended?

More info needed: 1. "blood cancer" could include myelome, lymphoma, leukemia, and other processes. 2. "third stage" -- if it means stage 3 -- isn't the only or necessarily the most important factor in determining treatment. Knowing when and how to treat a specific person is usually not amenable to a generic answer in 400 characters.
