What you can expect

Undergoing an allogeneic stem cell transplant involves:

• Undergoing high doses of cancer treatment (conditioning). During the conditioning process, you'll receive high doses of chemotherapy or radiation therapy to kill your cancer cells. What treatment you undergo depends on your disease and your particular situation.

  The cancer treatments used during the conditioning process carry a risk of side effects. Talk with your doctor about what you can expect from your treatment.

• Receiving an infusion of stem cells. Stem cells from a donor will be infused into your bloodstream, where they will travel to your bone marrow and begin creating new blood cells.
• Remaining under close medical care. After your transplant your care team will want to monitor you carefully for signs of complications. You may spend a few weeks in the hospital or nearby. Expect to undergo frequent blood tests and appointments to monitor your body's response to the transplant.

It takes a few weeks for the donor cells to settle in your bone marrow and begin making new cells. You may receive blood transfusions until your bone marrow recovers.
