For the study, researchers analyzed data from nearly 15,000 breast cancer patients who participated in one of three earlier studies (two in Sweden and one in the United States). Of those patients, 1,772 had interval breast cancer.
Compared to those without interval breast cancer, patients with interval breast cancer who also had another type of cancer were three times more likely to have a family history of multiple cancers. This suggests that rare genetic mutations may play a role in their cancers, according to Felix Grassmann, of the Karolinska Institute in Stockholm, and colleagues.
Their report was published online Oct. 22 in the journal Nature Communications.
The findings may be useful in updating cancer prevention programs, the researchers suggested in a journal news release.
That could include providing additional screenings for certain people and increasing awareness among interval breast cancer survivors and their relatives.
The study authors also said that further research is needed to pinpoint rare genetic mutations that may be associated with interval breast cancer and other cancers.
