Lymphoma Risk Higher if Father Was Older

DUARTE, Calif., May 27 (UPI) — Children born to older men have a higher risk of non-Hodgkin’s lymphoma, U.S. researchers found.

City of Hope National Medical Center research fellow Yani Lu used data from the California Teachers study, which tracks the health, lifestyle and demographic information of some 133,500 female teachers and administrators in the public schools’ retirement system in California.


Lu and colleagues focused on 110,999 women — 819 diagnosed with a hematological malignancy, or a blood cancer.

The study, published online ahead of print of the June 15 issue of the American Journal of Epidemiology, found study participants born to fathers age 40 and older had a 59 percent greater risk of non-Hodgkin’s lymphoma compared with similar women born to fathers age 25 and younger.

Children of older fathers have a greater chance of prostate and breast cancers in adulthood as well as some blood cancers during childhood.

“A man may think, ‘I can have a baby at 50 or 60 and live long enough to see him go through college,’” Lu said in a statement. “But there may be other risks for your child down the line, and you may want to be conscious of those risks.”
