Breast cancer doesn't only affect women: men can develop it too. How common is male breast cancer? What are its causes and symptoms? Raising awareness is key to early detection and effective treatment.
Statistics on Male Breast Cancer
Male breast cancer accounts for approximately 0.5% to 1% of all breast cancer cases. According to the American Cancer Society, an estimated 2,800 men in the United States will be diagnosed with breast cancer in 2025, and around 500 men are expected to die from the disease.
Causes of Breast Cancer in Men
Breast cancer in men develops in a similar way as in women. Although rare, it occurs when cells in the breast tissue grow uncontrollably. All individuals, regardless of gender, are born with a small amount of breast tissue, which can become cancerous under certain conditions. In cancer cells, the DNA contains faulty instructions that cause them to multiply rapidly and avoid normal cell death. These abnormal cells can form a mass known as a tumor. Over time, the tumor can invade and destroy healthy tissue, and in some cases, spread to other parts of the body, resulting in metastatic cancer. There are different types of male breast cancer, with ductal carcinoma, which begins in the milk ducts, being the most common.
Risk factors for male breast cancer include older age, particularly over 60, a family history of breast cancer, and elevated estrogen levels, which can result from conditions such as obesity or chronic liver disease.
Symptoms of Male Breast Cancer
Male breast cancer can present with a variety of symptoms. It's important to be aware of the following warning signs:
- A painless lump or swelling in the chest or armpit
- Nipple discharge, which may contain blood
- Changes in the size or shape of one side of the chest
- Sores or ulcers on the chest
- Changes to the nipple, such as inversion or a persistent rash
When breast cancer spreads beyond the breast, it can affect other parts of the body such as the bones, liver, lungs or brain. This is known as metastatic breast cancer. General symptoms of advanced disease may include:
- Persistent fatigue or lack of energy
- Loss of appetite or unexplained weight loss
- Nausea or feeling unwell without a clear cause
- Difficulty sleeping
Regular self-examination is important, as it helps men become familiar with what is normal for their chest. If you notice any of these symptoms or have any concerns, consult your general practitioner (GP) promptly. While these signs can be caused by other, non-cancerous conditions, it is essential to have them evaluated to rule out breast cancer.
How to Perform a Self-Exam for Male Breast Cancer
A self-exam for male breast cancer is similar to the method used for women. Begin by visually inspecting your chest for any changes in shape, size or skin texture. Next, with your fingers flat, gently press down in a circular motion, starting from the outer edge of the breast and moving inward. Feel for any unusual lumps, thickening or bumps. Check each breast one at a time, using your left hand to examine the right breast, and vice versa. Don’t forget to gently squeeze the nipples to check for any discharge.
Regular self-exams help you become familiar with your body and make it easier to notice any changes that should be brought to a doctor’s attention.
Male Breast Cancer Is Rare, But Early Detection Saves Lives
Because breast cancer is often perceived as a women’s disease, men may be more likely to ignore early symptoms, leading to later-stage diagnoses and potentially worse outcomes. This is why regular self-examination is crucial for both women and men. Early detection can significantly improve the chances of successful treatment.
While male breast cancer is rare, increasing research is helping to improve understanding and treatment of the disease. Continued efforts are essential to further develop tailored therapies and support strategies that address the unique aspects of breast cancer in men.
