Myeloma is a type of cancer. It occurs when the plasma cells (type of white blood cells) become malignant or cancerous. Plasma cells are also called B Lymphocytes and they are responsible for producing antibodies.
Like all blood cells, plasma cells are produced in the bone marrow and myeloma occurs mainly in the bone marrow of large bones. Eventually the myeloma cells break out and invade the bone causing 'osteomyeloma' - osteo=bone.
Myeloma cells also spread to other organs and parts of the body leading to 'multiple myeloma'

What is Grangers disease which is a form of osteomyeloma?
Granger's disease, also known as osteomyelitis, is a type of bone infection that can lead to inflammation and destruction of bone tissue. It is often caused by bacteria entering the bone through an open fracture, surgery, or bloodstream. Symptoms may include pain, swelling, fever, and redness in the affected area. Treatment typically involves antibiotics and, in some cases, surgery to remove infected tissue or drain abscesses.
How does cancer spread through the body?
cells can either travel in the blood stream, settle somewhere else, multiply and form a tumor, or an existing tumor can grow "roots" if you will, and a tumor can grow off of a root, or on the end of it. These new sites to which the cancer has spread are known as metastatic sites, and the cancer that spread through the process of metastasis (or disseminating, spreading) is referred to as "secondary cancer". For example, cancer that originates in the bone as a malignant osteoma can spread to the bone marrow and become secondary bone marrow cancer (or osteomyeloma; "oste/o-" means bone, "myelo-" means marrow, and "-oma" means a tumorous growth, indicating cancer.
