Question: Familial CLL?

 bhasaji - Sun Sep 06, 2009 4:39 am

My father had CLL at 46 years age, and he passed at 57 years in 2005. Recently, I discovered that his aunt ( real sister of his mother) also has CLL and she is 72 years.

Is is a familial CLL? Could it be? Is there any way I can find if I am predisposed to developing CLL? I am 37 years male.

Sister of my father has also developed Ca Breast recently.

ANy response is highly appreciated

User avatar Hello,
First degree relatives of CLL patients have been found in some studies to have a higher risk of CLL as well as other tumors a phenomenon referred to as familial aggregation. Although this disease is not hereditary and there is no evidence of genetic transmission. It may be that certain genes that run in a family make it more likely for family members to develop these tumors.

Although, there aren't any formal guidelines for special screening of family members of CLL patients, it would be a good idea to let your family doctor / Aunt's doctor know of your concern.

I am throwing in a few references for convenience.
