Intake of alcohol during pregnancy has been associated with childhood leukemia. A review published by the National Cancer Institute placed maternal alcohol consumption during pregnancy in the category of "suggestive" but concluded that the risk was not important.

Acute Lymphocytic Leukemia (ALL)

For ALL in children, maternal alcohol consumption during pregnancy is "unlikely to be an important risk factor for ALL"

Acute myeloid leukemia (AML)

A study concluded, "In conclusion, even though our study did not show a clear association between alcohol intake and leukemia risk, some of the patterns of the risk estimates (a possible J-shaped dose-response curve between alcohol intake and ALL, AML, and CLL risks, and the positive association between alcohol and CML), may be suggestive."

Childhood AML

"Three studies have reported an increased risk (approximately 1.5-2 fold) in mothers who drank alcoholic beverages during pregnancy. These associations have been particularly apparent in children diagnosed younger than three years of age.". "Maternal alcohol consumption during pregnancy increases the risk of infant leukemia, especially AML."

Acute non-lymphocytic leukemia (ANLL)

A study found that intrauterine exposure to alcohol doubled the risk for childhood ANLL.

Chronic Lymphocytic Leukemia (CLL)

Chronic Lymphocytic Leukemia

A study concluded, "In conclusion, even though our study did not show a clear association between alcohol intake and leukemia risk, some of the patterns of the risk estimates (a possible J-shaped dose-response curve between alcohol intake and ALL, AML, and CLL risks, and the positive association between alcohol and CML), may be suggestive."

Chronic myeloid leukemia (CML)

A population-based case-control study in Italy found a non-significant positive association between drinking and CML.

Hairy cell leukemia

A study concluded, "There was no association found for cigarette smoking, alcohol or coffee consumption and hairy cell leukemia."
