Myelofibrosis patients can eat lettuce. Myelofibrosis is a malignant disease of the blood system due to the proliferation of collagenous tissue in the bone marrow and the increase of fibrotic tissue leading to the reduction of hematopoietic tissue, which causes the bone marrow hematopoietic function to weaken or even fail, and the specific pathogenesis of the disease is not yet very clear. Lettuce will not affect the bone marrow hematopoietic ability of myelofibrosis patients. Myelofibrosis patients can eat lettuce. The diagnosis of myelofibrosis depends on bone marrow aspiration cytology, MPN gene test and bone marrow biopsy, etc. After the diagnosis is clear, it is necessary to promote bone marrow hematopoiesis and other treatments to raise the blood cell count. The disease is accompanied by an enlarged spleen, which can be minimized by targeted therapy with drugs such as rucotinib. Transplantation is also indicated. It is recommended that the patient should go to the hematology department in time, and the specialist should carefully evaluate the condition and formulate an individualized treatment plan, as well as formulate reasonable dietary recipes under the guidance of the specialist and dietitian.
