<s>[INST] Hi, my mum was first diagnosed with mutiple myloma then they later changed their statement that she was suffering from lymphoma and now they are saying its leukemia is there any similarities between this three? is their treatment similar? and lastly what are the symptoms for each one [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Multiple myeloma, leukemia and lymphoma, all are blood malignancies. Lymphoma involves lymph nodes and lymphatic system. Multiple myeloma involves myeloid cells of bone marrow. Leukemia involves white blood cells like leukocyte. So all are blood cancer involving different blood cells. Treatment protocols are also different. They do share some common symptoms like low grade fever, weakness, weight loss, anorexia etc. Bleeding through gums, joints and skin is common with leukemia. Bone pain and fractures are common with multiple myeloma. Cervical swelling due to enlarged lymph nodes is common in lymphoma. Hope I have solved your query. Wishing good health to your mother. Thanks. </s>
