Some : Some cases of breast cancer genetic mutations brca i and ii , her 2 some breast cancer run in families. In leukemias not enough proof of genetic mutations as in breast cancer ( I do not know ) how ever leukemias run in family members, especially cll and AML , may not be genetic, could be environmental.

CLL (chronic lymphocytic leukemias) is unique among the common leukemias in having no known familial tendency, and being the effect simply of dumb luck. If there are any risk factors, they remain elusive to real science. The others tend to run with Down's, ataxia-telangiectasia carrier state, and a few obscure illnesses.

Sometimes: Most breast cancers and most leukemias are not hereditary but there are hereditary types of both. Families that have breast cancer, leukemia, and sarcomas may have a rare genetic abnormality called li fraumeni syndrome. If you are concerned seek out a genetic counselor or high risk breast specialist.

Are chronic leukemia and breast cancer related?

Somewhat: Patients with chronic leukemia are twice as likely as the general population to develop other malignancies, including breast cancer. This likely has to do with chronic leukemia patients having a genetic predisposition, compromised immune systems, or just generally being older.

Sometimes.: It is estimated that 10-15% of all breast cancer cases in the us occur due to hereditary factors. This risk may be identified by doing a simple blood test to check for brca mutations. We generally advise testing family members with known breast cancers first before checking unaffected family.
