The Male Breast Cancer Study
Research area: Prevention and early diagnosis
The Male Breast Cancer Study was established in 2007 to pinpoint the precise genetic, environmental and lifestyle causes of breast cancer in men.
About the Male Breast Cancer Study
Many people don’t know that men can get breast cancer because they don’t think of men as having breasts. But anyone can get breast cancer.
The Male Breast Cancer Study is one of the largest studies into male breast cancer. The study will help identify people who are at risk of getting the disease and understand what can be done to lower the chances of develop it. It also aims to identify similarities and differences between breast cancer in men and women.
Key facts
-
400 men
Each year, around 400 men are diagnosed with breast cancer in the UK. -

Our investment
To date, we have invested around £299 million in world-class breast cancer research.
The Breast Cancer Now Male Breast Cancer Study is the largest collection of DNA and tumour samples from men with breast cancer in the world. We hope that by analysing data generated from these samples we’ll be able to understand what causes male breast cancer, how it differs from female breast cancer and how best to treat it.

Our Male Breast Cancer Study achievements
Since it was established over 15 years ago, our scientists have been working hard to uncover how and why breast cancer develops in men. And we’re already seeing the impact.
Genetic changes
Scientists found genetic changes that significantly increase the risk of breast cancer in men.
Obesity increases risk
The study contributed to global research showing obesity increases the risk of male breast cancer.
The link with infertility
Researchers found that men with breast cancer were more likely to report fertility issues.
