About Blood cancer
What are blood cancers?
Most blood cancers,
also called hematologic 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.
Types of blood cancers
The three main types
of blood cancer are leukemia, lymphoma and myeloma:
Leukemia is a blood cancer that originates in the blood
and bone marrow.
It occurs when the
body creates too many abnormal white blood cells and interferes with the bone
marrow’s ability to make red blood cells and platelets.
Non-Hodgkin
lymphoma is a blood
cancer that develops in the lymphatic system from cells called lymphocytes, a
type of white blood cell that helps the body fight infections.
Hodgkin lymphoma is a blood cancer that develops in the
lymphatic system from cells called lymphocytes. Hodgkin lymphoma is
characterized by the presence of an abnormal lymphocyte called the
Reed-Sternberg cell.
Multiple myeloma is a blood cancer that begins in the
blood’s plasma cells, a type of white blood cell made in the bone marrow.
Blood cancer symptoms
Some common blood
cancer symptoms include:
- Fever, chills
- Persistent fatigue, weakness
- Loss of appetite, nausea
- Unexplained weight loss
- Night sweats
- Bone/joint pain
- Abdominal discomfort
- Headaches
- Shortness of breath
- Frequent infections
- Itchy skin or skin rash
- Swollen lymph nodes in the
neck, underarms or groin
Blood cancer treatment and therapy options
Treatment for blood
cancer depends on the type of cancer, your age, how fast the cancer is
progressing, where the cancer has spread and other factors. Some common blood
cancer treatments include:
Stem cell
transplantation: A stem cell transplant infuses healthy blood-forming stem cells
into the body. Stem cells may be collected from the bone marrow, circulating
blood and umbilical cord blood.
Chemotherapy: Chemotherapy uses anticancer drugs to
interfere with and stop the growth of cancer cells in the body. Chemotherapy
for blood cancer sometimes involves giving several drugs together in a set
regimen. This treatment may also be given before a stem cell transplant.
Radiation
therapy: Radiation
therapy may be used to destroy cancer cells or to relieve pain or discomfort.
It may also be given before a stem cell transplant.
