The ACS website provides more information about how each of these factors contributes to increased breast cancer risk. Reducing risk Men who want to reduce their risk of developing breast cancer can maintain ideal body weight and restrict alcohol consumption. However, because the cause of most breast cancers is unknown, there is little men can do to prevent the disease. With that said, it is important for men to perform self-examinations and seek medical attention for any lumps as soon as possible. Many men tend to ignore early signs of lumps and will go to the doctor only after the lump has gotten bigger. As a result men are typically diagnosed with more advanced stages of cancer than women.
