Breast Cancer and Prostate May Cluster In Families

A new study has confirmed that women who have close male relatives that tend to have prostate cancer are at a higher risk of being diagnosed with breast cancer.

The recent findings from the study conducted goes to confirm the results which were found in a study that was conducted back in 1994 in the Journal of the National Cancer Institute.

According to Jennifer L. Beebe-Dimmer, a cancer specialist at a Karmanos Cancer Institute which is located in Detroit, the recent studies is not something new.

“This is not the first study to examine this relationship, but it is one of the larger to date, if not the largest study,” she said.

She went on further to state that cancer is generally a DNA disease and as a result the presence of clustering in families usually indicate that prostrate and breast cancer may actually have common genes.
The study, which was led by Beebe-Dimmer, saw data of more than 78,000 women who are 50 years and above and are in Women’s Health Initiative being used. In addition to that all women who participated in the study were cancer free when the study began.
The study which began in 1993 saw most of the women opting to continue taking part in the study and by 2009, 3,506 cases of breast cancer was discovered among the original group.

The findings of the study revealed that 20% of the women who tested and found out that they have breast cancer had a sister, mother or daughter (first degree relative) who had breast cancer. There was also a similar case when it comes to prostate cancer as 11% of the women who reported to have cancer had a first-degree relative with prostate cancer.
