Is Leukaemia genetic

Answer 1

In some cases Leukemia is genetic.

The ALL form of the disease most commonly occurs in younger children ages 2 to 8, with a peak incidence at age 4. But it can affect all age groups.

Kids have a 20% to 25% chance of developing ALL or AML if they have an identical twin who was diagnosed with the illness before age 6. In general, nonidentical twins and other siblings of children with leukemia have two to four times the average risk of developing this illness.

Children who have inherited certain genetic problems --- such as Li-Fraumeni syndrome, Down syndrome, Kleinfelter syndrome,neurofibromatosis, ataxia telangectasia, or Fanconi's anemia --- have a higher risk of developing leukemia, as do kids who are receiving medical drugs to suppress their immune systems after organ transplants.

Children who have received prior radiation or chemotherapy for other types of cancer also have a higher risk for leukemia, usually within the first 8 years after treatment.

In most cases, neither parents nor kids have control over the factors that trigger leukemia, although current studies are investigating the possibility that some environmental factors may increase the risk that a child will develop the disease. Most leukemias arise from noninherited mutations (changes) in the genes of growing blood cells. Because these errors occur randomly and unpredictably, there is currently no effective way to prevent most types of leukemia.

To limit the risk of prenatal radiation exposure as a trigger for leukemia (especially ALL), women who are pregnant or who suspect that they might be pregnant should always inform their doctors before undergoing tests or medical procedures that involve radiation (such as X-rays).

Regular checkups can spot early symptoms of leukemia in the relatively rare cases where this cancer is linked to an inherited genetic problem, to prior cancer treatment, or to use of immunosuppressive drugs for organ transplants.

Answer 2

Some forms of leukemia can have a genetic component, meaning that certain genetic mutations can increase a person's risk of developing the disease. However, most cases of leukemia are not directly inherited and are instead a result of acquired mutations over a person's lifetime.

Answer 3

Leukemia is a cancer of the bone marrow. If you mean if is hereditary, that is unknown at the moment. There have been signs, but very rare.
