Will people who have had breast cancer likely to get myelodysplastic syndrome?

Side effect: This is a side effect of some chemotherapy agents. This side effect does not happen to everyone. It is important to follow up with your medical oncologist after treatment is complete so they can keep track of your blood cell counts. If have concerns that you may have developed this, speak to your doctor.

Low risk: Depending on the chemo used, the risk is less than 1-2%. I agree that routine blood tests after chemo is complete is important. Hope this helps.

Not very common: While it is true that the risk to develop mds .After treatment for breast cancer ( surgery plus radiation/chemo) is higher than the risk of mds in general population, but the real incidence is not very high , it is thought that perhaps combination of radiation and certain chemotherapy are related to this risk follow up with your oncologist for your history of breast ca and other related problem.

Possibly: If the breast cancer patient has undergone treatment with radiation and/or chemotherapy, these types of therapy may increase the risk for various secondary malignancies (cancers) including myelodysplastic syndrome which is a form of bone marrow cancer.
