What to know about leukemia

 Leukemia is a cancer of the blood or bone marrow. Bone marrow produces blood cells. Leukemia can develop due to a problem with blood cell production. It usually affects the leukocytes, or white blood cells.

Leukemia is most likely to affect people over the age of 55 years, but it is also the most common cancer in those aged under 15 years.

The National Cancer Institute estimates that 61,780 people will receive a diagnosis of leukemia in 2019. They also predict that leukemia will cause 22,840 deaths in the same year.

Acute leukemia develops quickly and worsens rapidly, but chronic leukemia gets worse over time. There are several different types of leukemia, and the best course of treatment and a person’s chance of survival depends on which type they have.

In this article, we provide an overview of leukemia, causes, treatment, type, and symptoms.

Causes

Leukemia develops when the DNA of developing blood cells, mainly white cells, incurs damage. This causes the blood cells to grow and divide uncontrollably.

Healthy blood cells die, and new cells replace them. These develop in the bone marrow.

The abnormal blood cells do not die at a natural point in their life cycle. Instead, they build up and occupy more space.

As the bone marrow produces more cancer cells, they begin to overcrowd the blood, preventing the healthy white blood cells from growing and functioning normally.

Eventually, the cancerous cells outnumber healthy cells in the blood.
