Cancer Types
Cancer is a group of diseases, each with its own name, treatment and
chances for control or cure. Cancer occurs when
abnormal cells begin to multiply and grow
uncontrollably, crowding out the normal cells.
Although cancer research has made tremendous
advances in the last 50 years, scientists still do
not fully understand why normal cells mature and
cancerous cells do not.
The types of cancer
most common in children differ from those in adults.
Leukemias (cancers of the blood-producing tissues),
lymphomas (cancers
of the lymphatic system) and
brain tumours are
the most common types of childhood cancers. Solid
tumours, which affect other parts of the body such
as arms or legs, are less common in young people.
Bone tumours are a
type of solid tumour. |
