Pls Doctor Help me!!! Very concerned!!!!

To: Dr. Kamal Saini

Hi! I am 26 Female, and I am concerned about my Platelet count!!! I went to the doctor just for a physical and he ran some blood work on me. The results came back that everything was normal except for my platelet count. The normal is 450, but my mine came back 455. A week later I went to the ER becauase I had a really bad gastritis attack, and they did a CBC there, and this time my platelets came back higher 460!! I am really concerned and I am not sure what is going on. I spoke to my doctor and he said that I need another blood test, but I am scared to go get one beacause I am afraid that they my platelets will keep increasing and that I will get diagnosed with cancer!!! My primary doctor and my ER doctor did not show much concern about my platelet count! and I am not sure why??? and niether one can really explain to me what is going on! I am very scared and concerned! I hope that someone can shed some light on this situation. I am terrified I am have some clotting disorder or I have some type of cancer!!!  Please help!!! I would really appreciate it!!
