    Let's set the record straight:

    "Its prognosis, despite therapy, is generally poor," ; that may have been true 10 years ago but now MM is more treatable with a much more positive prognosis.

    MMRC: "While a myeloma diagnosis can be overwhelming, it is important to remember that there are several promising new therapies that are helping patients live longer, healthier lives

    MM is a blood cancer, cancer of the plasma cell, not a "cancerous tumor of muscles"


    Now to answer your questions:

    MM is cancer of the Plasma Cell and CLL is cancer of the T or B lymphocytes.

    There are a ton of other differences - MM progression and side effects are VERY different than CLL, so are the treatments.

    This is a very complicated question;

    The Leukemia & Lymphoma Society has good overviews of both cancers and the specific genetic changes that shows the differences.


    for specifics on MM:

    Multiple myeloma (also known as MM, myeloma, plasma cell myeloma, or as Kahler's disease after Otto Kahler) is a type of cancer of plasma cells, immune system cells in bone marrow that produce antibodies. Its prognosis, despite therapy, is generally poor, and treatment may involve chemotherapy and stem cell transplant. It is part of the broad group of diseases called hematological malignancies. Myeloma bone pain usually involves the spine and ribs, and worsens with activity. Persistent localized pain may indicate a pathological fracture. Involvement of the vertebrae may lead to spinal cord compression. Myeloma bone disease is due to proliferation of tumor cells and release of IL-1, also known as osteoclast activating factor (OAF), which stimulates osteoclasts to break down bone. These bone lesions are lytic in nature and are best seen in plain radiographs, which may show a "punched-out" resorptive lesions. The breakdown of bone also leads to release of calcium into the blood, leading to hypercalcemia and its associated symptoms.


    In chronic leukemias, the cancer starts in the blood cells made in the bone marrow. The cells mature and only a few remain as immature cells. However, even though the cells mature and appear normal, they do not function as normal cells. Depending on the type of white blood cell that is involved, chronic leukemia can be classified as chronic lymphocytic leukemia or chronic myelogenous leukemia. Chronic leukemias develop very gradually. The abnormal lymphocytes multiply slowly, but in a poorly regulated manner. They live much longer and thus their numbers build up in the body. The two types of chronic

    leukemias can be easily distinguished under the microscope. Chronic lymphocytic leukemia (CLL) involves the T or B lymphocytes. B cell abnormalities are more common than T cell abnormalities. T cells are affected in only 5% of the patients. The T and B lymphocytes can be differentiated from the other types of white blood cells based on their size and by the absence of granules inside them. In chronic myelogenous leukemia (CML), the cells that are affected are the granulocytes. Chronic lymphocytic leukemia (CLL) often shows no early symptoms and may remain undetected for a long time. Chronic myelogenous leukemia (CML), on the other hand, may progress to a more acute form.

    Multiple myeloma is cancerous tumor of muscles and chronic lymphocytic leukemia is the blood cancer caused by the abnormal proliferation of white blood cells -lymphocytes. Chronic means infection has taken place before long time.

      MM is not "cancerous tumor" of muscles!! It's cancer of plasma cells in the blood.
