Acute lymphoblastic leukaemia (ALL)
Acute lymphoblastic leukaemia (ALL) is a fast-growing type of leukaemia (blood cancer), which affects lymphocyte white blood cells.
ALL is not a common cancer. Fewer than 50 people are diagnosed with ALL in Ireland every year. It is most common in adolescents and young people between the ages of 15 and 25.
What is acute lymphoblastic leukaemia (ALL)?
Acute lymphoblastic leukaemia (ALL) is a fast-growing type of leukaemia (cancer of the blood) which affects lymphocyte white blood cells.
The cancer means you may not have enough healthy cells in your blood. This can cause problems with fighting infection, carrying oxygen and bleeding.
