Brief Answer: ITP does not turn to cancer Detailed Answer: Hi Thanks for your query. ITP is a disorder where the body's immunity kills its own platelets. Hence the treatment is some form of immune suppression, whereby this immune response is dampened so that the platelet count improves. Steroids like dexamethasone are for the same reason. However, sometimes when the dose of steroids is reduced, the platelet count falls. At this time other medicines are used. Rituximab is an anti B cell antibody which can also act in ITP by acting against the B lymphoid cells and thereby dampening the immune response. It is also used in B cell lymphomas. but ITP has nothing to do with B cell lymphomas or leukemia. Overall I feel that she is on the right track. You can take a second opinion but I think she should do just fine with this. Hope I have answered your query. I will be available to answer further followup queries, if any.
