Hi @candicemitchell320 and welcome to Mayo Clinic Connect. This is a wonderful forum where people help each other through shared experiences. As you can see there are a number of other members who also have high platelets for one reason or another. However we are not medical professionals so we can’t diagnose conditions.

How high is your platelet count? Have you had this condition long or has it developed recently?

You had a bone marrow biopsy which also showed high platelets. The main goal of the BMBX is to determine what is causing the high platelet count by going to the source of blood production...the bone marrow.

Did your oncologist/hematologist review the results with you and give a diagnosis? If not, you need some clarification and answers. So call the doctor’s office and speak to the nurse practitioner or set up a consultation. After going through all of that you have a right to know for some peace of mind and a plan of action.

I’m sure there will be other members on this forum who can provide you with some personal insights...in the meantime I’ve posted some information from the Mayo Clinic website on high platelets.

And hello here from another Volunteer Mentor. Lori has given you some excellent information and direction. All I can add is reading in your past that your oncologist ordered a bone marrow biopsy in response to the high platelet count, so he/she is already addressing it. Just follow up as Lori suggested and keep asking questions and getting the answers you want and need. We are all about self advocacy and you are already on that path. Welcome to Connect. I hope that you come back and let us know how you are doing. Peace, Nancy.
