Most blood cancers start in the bone marrow, which is where blood is produced. Blood cancers occur when abnormal blood cells start growing out of control, interrupting the function of normal blood cells, which fight off infection and produce new blood cells.
Diagnosis often starts with a physical examination to check your general health. Your doctor will review your health history, examine your body and lymph nodes, and look for any signs of infection or bruising.
Different types of tests and procedures may be used to diagnose blood cancer. What you need will depend on the type of blood cancer suspected.
We don't know what causes blood cancer. Unlike other cancers, it seems that people's lifestyle does not affect their likelihood of developing blood cancer. It is not passed on genetically but developed during a person's lifetime. There are some common risk factors
There are over a 100 different types of blood cancer that affect people at different life stages. Below we list the three most common blood cancers and share symptoms, risk factors and treatments.
