Cancer: Lung, stomach, breast, and ovarian cancers, as well as lymphoma, can cause high platelet counts. Additional blood testing, imaging scans, or a biopsy can test for cancer. Anemia: People with iron deficiency or hemolytic anemia may have high platelets. Further blood testing can detect most forms of anemia.
A high platelet count can cause too much clotting in your blood vessels. Or it can cause too much bleeding if the platelets interfere with clotting. It could be a sign of: Immune system problems. Infections.

The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes. Primary malignant neoplasms overlapping site boundaries.
