Cancer can be considered as a group of diseases
caused by the abnormal growth of cells which eventually spreads to other parts
of the body. All tumors are not caused as a result of cancerous cells. There are
benign tumors also. Abnormal lumps in body, prolonged cough, unexplained
weight loss, abnormal bleeding, and variations in bowel movements etc can be considered as symptoms of cancer. It is believed that there are about 100
types of cancers that affects different organs and systems of human body.
Irregular growth of blood cells is the cause of
blood cancer. There are red blood cells, platelets and white blood cells. These
three types of blood cells are formed by maturing the bone marrow where blood
is produced from the stem cells. Abnormal cell growth which results in
cancerous cells, prevent the blood in performing its functions like preventing
bleeding and fighting infections. Blood cancer can be grouped into three major
categories. They are leukemia, lymphoma and myeloma.
Leukemia: Abnormal production of while cells is the cause for
leukemia. This abnormal white blood cells impair human body’s ability to fight infection.
They also impair the ability of bone marrow to produce red blood cells as well
as platelets.
Lymphoma: Lymphoma is
the cancer that affects the lymphatic system of the human body resulting in the
removal of excess fluids and the production of immune cells. The unusual
lymphocytes changes to lymphoma cells multiplying themselves at faster rates
and accumulating in the lymph nodes and nearby tissues. As time passes these cancerous cells destroy
the human immune system.
Myeloma: Plasma cells in the blood are responsible for the
production of white blood cells that produce immunoglobulin. In myeloma plasma cells are transformed to
harmful myeloma cells and it interferes in the production of blood cells. It is
believed that the functional immunoglobulin produced by healthy plasma
degenerates quickly in multiple myeloma patients.
