@mattymatilda and @amyboylan1, CHIP stands for clonal hematopoiesis of indeterminate potential (CHIP). In plain language, clonal hematopoiesis is age related. In some people, the blood (hematopoietic) stem cells start making cells with a genetic mutation (error) that make them divide more rapidly than normal. Most people don't have symptoms and never even know they have this mutation. CHIP can lead to blood cancers, especially myelodysplastic syndrome and acute myeloid leukemia. This is rare, however, and most people with CH never get blood cancer. Read more https://www.mskcc.org/cancer-care/types/leukemias/risk-factors/clonal-hematopoiesis-ch
