Hi @arbutus, while we’re waiting for other members to reply about their experiences with Mantle Cell Lymphoma, could you tell me what infusions your husband received?
There are several possible treatments so it might be helpful to know the name to see if others had the same medication.

It’s not unusual after chemo infusions for blood numbers to drop along with the cancer cells. Those treatments often target fast growing cells. Unfortunately they don’t differentiate and so blood cells, along with cancer cells involved. The effects are usually felt around 7-10 days after treatment with fatigue and weakness. Once the blood numbers start regenerating, especially the white blood cells, then he should feel a little perkier.

I hope he gets good news at the oncologist tomorrow! Will you let me know please?
