Breast cancer in men is rare, but it can grow and spread like any other cancer if left untreated. We offer precise diagnostic testing for men at the Abramson Cancer Center. Our specialists pinpoint the characteristics of male breast cancer and provide personalized, effective treatment.
What Is Male Breast Cancer?
Just like women, men have breast tissue that can develop cancer. It begins in either milk ducts (ductal cancer) or glands (lobular cancer), even though these breast parts are not functional in men.
The risk factors for male breast cancer are similar to other types of breast cancer. Male breast cancer can occur at any age, but typically develops in men between the ages of 60 and 70. Additional conditions that increase risk factors for men include:
- Undescended testicle
- Testicular swelling, due to adult-onset mumps
- Removal of one or more testicles
- Estrogen treatment, given as hormone therapy for men with prostate cancer
Male Breast Cancer Symptoms & Diagnosis
Men are not screened for breast cancer, so any changes to your breast should be checked by a doctor. While some men may have no symptoms, the first sign of male breast cancer is usually a lump that feels like a hard knot. Others may exhibit the more common symptoms of breast cancer.
If breast cancer is suspected, we use breast cancer imaging and biopsy to diagnose male breast cancer. Your care team will check your lymph nodes to determine the stage of breast cancer.
Types of Breast Cancer in Men
Identifying the type of breast cancer helps us determine the most effective treatment. Men can be diagnosed with several different types of breast cancer, including:
A pathologist studies breast cancer tissue to identify hormone receptors and human epidermal growth factor receptor 2 (HER2). These proteins found on some breast cancer cells fuel the cancer’s growth. About 90 percent of male breast cancers are hormone receptor-positive and treatable with hormone therapy. If cancer is HER2-positive, we treat it with targeted therapy. If a tumor does not have any receptors, it is called triple negative breast cancer.
