Will there be long-term side-effects from my chemotherapy treatment?

Some of the long-term side effects chemotherapy tend to be directed against the bone marrow, which makes the blood. It's not unusual for somebody to have an abnormal complete blood count after finishing chemotherapy, perhaps even for years. The worst thing that could happen would even be to develop a leukemia, secondary from chemotherapy, although that's pretty rare. In large studies of breast cancer patients, that happens less than one half of one percent of the time.
