Male infertility may increase the risk of breast cancer in men


  • Breast cancer is said to be aggressive when cancer cells outgrow the initial tumor.
  • According to the National Cancer Institute, when it affects men, it is usually infiltrative ductal carcinoma.
  • The course and management of the disease are similar in men and women.

It is a rare cancer, with a lesser known, uncertain cause: male breast cancer. According to the National Cancer Institute, it represents less than 1% of all breast cancers diagnosed each year in France. In a research published in breast cancer research, a British team investigated the causes of disease in humans. According to their findings, it may be linked to infertility.

about 2,000 attendees

In all, scientists from the London Cancer Research Institute interviewed 1,998 men living in Wales or England, all with breast cancer. Participants answered a variety of questions, including those about their fertility and that of their partner. A total of 5.6% of them reported suffering from infertility and 19.2% had no children.

Their data was then compared with those of the 1597 men who formed the control group. The study authors then observed that men who had breast cancer were more likely to report fertility problems, and that they had more childless men than the control group. So they concluded that infertile men have twice the risk of developing invasive breast cancer compared to men without fertility problems.

Other possible causes were also examined by the authors of this study. Alcohol consumption, smoking, family history of breast cancer and liver disease were taken into account, but the researchers found “There is no strong evidence that these factors influenced the results”,

Some cases, difficult to analyze

,The causes of breast cancer in men are largely unknown, partly because it is rare and also because previous studies were small.”Michael Jones, the lead author of the study, says. in an interview science and the future, he explains that it took him twelve years to find enough patients to do this research. But it is important for them to keep working on this theme. ,The evidence presented in our study suggests that the relationship between infertility and breast cancer needs to be confirmed by further research and that future investigations into potential underlying factors such as hormonal imbalances are needed.”
