Myeloma

Myeloma begins when a plasma cell becomes abnormal. The abnormal cell divides to make copies of itself. The new cells divide again and again, making more and more abnormal cells. These abnormal plasma cells are called myeloma cells.

In time, myeloma cells collect in the bone marrow. They may damage the solid part of the bone. When myeloma cells collect in several of your bones, the disease is called "multiple myeloma." This disease may also harm other tissues and organs, such as the kidneys.

Myeloma cells make antibodies called M proteins and other proteins. These proteins can collect in the blood, urine, and organs

Common symptoms of multiple myeloma include:

• Bone pain, usually in the back and ribs
• Broken bones, usually in the spine
• Feeling weak and very tired
• Feeling very thirsty
• Frequent infections and fevers
• Weight loss
• Nausea or constipation
• Frequent urination

Most often, these symptoms are not due to cancer. Other health problems may also cause these symptoms. Only a doctor can tell for sure. Anyone with these symptoms should tell the doctor so that problems can be diagnosed and treated as early as possible
