There are things, apart from platelet cancer, that could cause increased number however do not necessarily result in blood clot that could kill you. The bleeding may be releasing chemicals to stimulate production and other inflammatory process may do the same. The important thing is that you are going to see a Heamatologist that could evaluate and explain to you better why you have high platelets.
