Radiation
Large doses of Sr-90 emission from nuclear reactor accidents, nicknamed bone seeker increases the risk of bone cancer and leukemia in animals and is presumed to do so in people. Genetic conditions
Some people have a genetic predisposition towards developing leukemia. This predisposition is demonstrated by family histories and twin studies. The affected people may have a single gene or multiple genes in common. In some cases, families tend to develop the same kinds of leukemia as other members; in other families, affected people may develop different forms of leukemia or related blood cancers.In addition to these genetic issues, people with chromosomal abnormalities or certain other genetic conditions have a greater risk of leukemia. For example, people with Down syndrome have a significantly increased risk of developing forms of acute leukemia (especially acute myeloid leukemia), and Fanconi anemia is a risk factor for developing acute myeloid leukemia. Mutation in SPRED1 gene has been associated with a predisposition to childhood leukemia.Chronic myelogenous leukemia is associated with a genetic abnormality called the Philadelphia translocation; 95% of people with CML carry the Philadelphia mutation, although this is not exclusive to CML and can be observed in people with other types of leukemia. Non-ionizing radiation
Whether or not non-ionizing radiation causes leukemia has been studied for several decades. The International Agency for Research on Cancer expert working group undertook a detailed review of all data on static and extremely low frequency electromagnetic energy, which occurs naturally and in association with the generation, transmission, and use of electrical power.
Ethinylestradiol/norethisterone acetate (EE/NETA), or ethinylestradiol/norethindrone acetate, is a combination of ethinylestradiol (EE) and norethisterone acetate (NETA) which is used as birth control and menopausal hormone therapy. EE is an estrogen, while norethisterone acetate (NETA) is a progestin. It is taken by mouth. Some preparations of EE/NETA used in birth control additionally contain an iron supplement in the form of ferrous fumarate.In 2019, it was the 42nd most commonly prescribed medication in the United States, with more than 16 million prescriptions.
