  Although breast cancer is typically synonymous as a disease that commonly occurs in women, it does occur in men as well. This is because although minimal in quantity, men do have breast tissue that has the potential to become malignant similarly to women, albeit much less commonly. While male breast cancer (MBC) is rare, only occurring in 1% of all breast cancers, it does occur, and it is important to be cognizant of its reality and potential. This activity examines when this condition should be considered in the differential diagnosis and how to evaluate it properly. This activity highlights the role of the interprofessional team in caring for patients with this condition. […] In the United States (US), there are about 2800 cases of male breast cancer annually. Unfortunately, men with breast cancer are often diagnosed late and have high mortality. However, stage for stage, the survival between men and women is similar.

  If there is a chance you have breast cancer, your doctor will want to get a complete personal and family medical history. This may give some clues about the cause of any symptoms you are having and if you might be at increased risk for breast cancer. […] A complete breast exam will be done to find any lumps or suspicious areas and to feel their texture, size, and relationship to the skin and muscle. […] If you have signs or symptoms that could mean breast cancer or another breast disease, your doctor might recommend one or more or the following imaging tests. […] A mammogram is a low dose x-ray exam of the breast that allows doctors called radiologists to look for changes in breast tissue. […] It is called a diagnostic mammogram when it is done because problems are present. […] The results of this test might suggest that a biopsy is needed to tell if the abnormal area is cancer.

  Men may not realize that, for them too, any changes in their breasts, including lumps in the chest or underarm area or changes to the nipple could be a sign of breast cancer and should be checked out by a doctor. […] Since men are usually less familiar with its signs and symptoms and because many are unaware that they can be affected by it, their breast cancer is often not diagnosed until it’s in a later, more advanced stage. […] Your doctor will begin to make a diagnosis by asking about your symptoms, whether you have taken or are currently taking certain medications associated with breast cancer, and whether you have any other known risk factors. A breast exam is also an important part of diagnosis. Your doctor will visually examine and feel your chest/breasts for signs of breast cancer.

  ABOUT 1 IN 550 MEN ARE DIAGNOSED […] Breast cancer in men […] In Australia, about one in 550 men will be diagnosed with breast cancer in their lifetime. […] It is important that men speak with their doctor as soon as possible if they notice any new or unusual breast changes. […] Cancer Australia recommends that men who detect any new or unusual breast changes see their doctor without delay. If the changes are caused by cancer, finding breast cancer early improves the chances that it can be treated successfully. […] Diagnosis of breast cancer in men […] Your doctor will investigate any new or unusual breast changes using a variety of diagnostic tests. These tests are the same as the ones used to study breast changes in women. They may include: Clinical breast examination, and taking a complete personal medical history. Mammogram – a low level x-ray of the breast. Though mammograms are not recommended for male breast cancer screening in Australia, they can be used to help diagnose breast cancer in men. Ultrasound – an imaging technique that uses sound waves to look at breast changes. It may help to determine whether a lump found in the breast is a fluid-filled cyst (which is unlikely to be cancer) or solid (which may require further testing to ensure it is not cancer). Biopsy – your doctor may recommend a biopsy if an abnormality is found during clinical examination and/or imaging tests. A biopsy involves removing a small sample of tissue and a specialist examining the sample under microscope. […] If you are diagnosed with breast cancer, your doctor may send you for further tests to help determine the extent of cancer spread in the body. Additional tests will be done to determine the molecular characteristics of the tumour, such the cancer’s hormone receptor status. These tests will help you and your doctors decide on the best treatment options.

  Additional tests are required for diagnosis. Your doctor may order imaging tests such as a mammogram, ultrasound, or a magnetic resonance imaging (MRI) study of the affected breast. But to make a definitive diagnosis, a biopsy of the breast tissue is necessary. In this procedure, a small piece of breast tissue is removed, usually with a needle (though sometimes a surgical biopsy is required). A pathologist will analyze the tissue sample to check for the presence of cancer cells, and, if they are present, their hormone receptor and HER2 status. […] If the biopsy confirms a diagnosis of breast cancer, your doctor will order more tests to see whether the cancer has spread beyond the breast. This is known as staging. It may involve additional imaging tests such as a chest X-ray, positron emission tomography (PET), or a bone scan. In some cases, a sentinel lymph node biopsy is necessary.

  A biopsy is done if the results of either a physical examination or imaging tests, such as a mammogram or ultrasound, show a concerning change in the breast. During a breast biopsy, a sample of tissue is taken from the breast. A pathologist a doctor who is trained to diagnose disease then examines the cells or tissue under a microscope to determine whether or not they are cancerous. […] There are different types of biopsy methods. These include: […] A core needle biopsy may be used if the pathologist needs a larger tissue sample than what can be obtained with a fine needle aspiration. It can also be used if the tissue removed during a fine needle aspiration did not yield a definitive diagnosis. […] A surgical biopsy may be done if other biopsy procedures do not provide a definitive diagnosis. A surgical biopsy is also performed if the suspicious area is too deep or too shallow for a core needle biopsy.

  Similar to breast cancer in women, the diagnosis of MBC is made by a triple assessment, which includes clinical assessment, mammography, ultrasonography, and core biopsy. Mammography is an effective diagnostic method with a sensitivity of 92% and a specificity of 90%; although due to size and volume differences in male breasts, this modality may be limited at times. Given this, ultrasound-guided core biopsy gives the most definitive diagnosis of MBC and is preferred over fine-needle aspiration.

  Most male breast cancers (~80%) are hormone receptor positive, 15% overexpress human epidermal growth factor receptor 2 (HER2), and 4% are triple negative (estrogen receptor, progesterone receptor, and HER2 negative). […] The US Food and Drug Administration (FDA) has issued a draft guidance encouraging the inclusion of male patients in breast cancer clinical trials, noting that many treatments are approved for women only and further data may be necessary to support approval for use in men. […] Recommendations for use of systemic therapy in male breast cancer are generally the same as in female breast cancer, because the rarity of male breast cancer has precluded the performance of clinical studies. […] ASCO guidelines recommend that men with advanced or metastatic, hormone receptor positive, HER2-negative breast cancer should be offered endocrine therapy as first-line therapy, except in cases of visceral crisis or rapidly progressive disease.

  Most breast cancers in men are estrogen receptor (ER)positive invasive ductal carcinoma. […] Even when a man sees his primary care physician with unusual chest symptoms, neither the doctor nor the patient expects breast cancerand so it often goes undiagnosed until it is more advanced. […] Unfortunately, there has been little research in male breast cancer, especially in how best to treat it, in part because of the diseases rarity and lack of surveillance. […] Men are often excluded fromor at least not actively recruited tobreast cancer clinical trials. […] As a result, treatment in men is much the same as treatment in women, with anti-hormone drugs such as tamoxifen and chemotherapy. […] Pioneering work by Dr. Fatima Cardoso and the BCRF-supported International Male Breast Cancer Program suggests that men are frequently undertreated for breast cancer.

  All newly-diagnosed breast cancers should be tested for HER2 because the outlook for people with HER2-positive cancers is improved if drugs that target the HER2 protein, such as trastuzumab (Herceptin) and lapatinib (Tykerb) are used as part of treatment. […] Doctors often divide invasive breast cancers into groups based on the presence of hormone receptors (ER and PR) and whether or not the cancer has too much HER2. […] Breast cancers in men that are hormone receptor-positive can be treated with hormone therapy drugs that lower estrogen levels, block estrogen receptors, or affect androgen (male hormone) levels. […] If the breast cancer cells don’t have either estrogen or progesterone receptors, they are said to be hormone receptor-negative (or just hormone-negative). Treatment with hormone therapy drugs is not helpful for these cancers.

  Breast cancer is classified in different ways, based on the results of lab tests after biopsy or surgery. Breast cancer is given a type, based on the type of cells it started from; a grade, based on how the cells look and how quickly they grow; and other classifications based on the results of tests for different hormone receptors or genes or proteins in the cancer cells. […] The biopsy is also used to determine the cancer’s type, such as invasive ductal carcinoma or invasive lobular carcinoma. […] Cancer cells are given a grade when they are removed from the breast and checked in the lab. The grade is based on how much the cancer cells look like normal breast cells. […] The grade is used to help predict your outcome (prognosis) and help figure out what treatments might work best. […] Knowing the hormone receptor status is important in deciding treatment options.

  Men tend to be diagnosed with breast cancers that are hormone receptor-positive and HER2-negative. […] The spread of cancer from breast to lymph nodes and other parts of the body in men appears to be similar to what women experience. […] The stage of breast cancer is determined by your care team based on: The size and location of the cancer, Whether it has spread to nearby lymph nodes or other parts of the body, The grade of the tumoror how likely it is to grow and spread, Whether certain biomarkershormone receptors or other proteinsare present. […] Tests to help with determining the stage of the cancer are: A biopsy of the sentinel lymph nodes, which are removed during surgery, A chest X-ray or CT scan, A bone scan, in which radioactive material is injected into a vein and then can be detected by a scanner, A PET scan, which scans the body after glucose is injected in a vein (malignant cells are brighter in the picture).

  Men with breast cancer experience unique physical and emotional challenges. […] Evidence suggests that MBC is mostly diagnosed late (49%) when the disease is more advanced compared to women (33%) leading to relatively worse prognosis. […] Consequently, MBCs are mainly diagnosed with more severe clinical manifestations with relatively complex tumour characteristics (i.e., larger sizes and extensive lymph node involvement), associated with higher proportions of positive hormone receptors, which mostly results in prolonged treatment delay, and metastasis of the disease at diagnosis compared to female breast cancer. […] Treatment for MBC has mainly been informed by available evidence for female breast cancer, and no randomised data exists for optimal management strategies for men including surgery, systemic therapy, and radiation.

  The authors determined that nearly 64.2% of patients felt moderate (or higher) embarrassment during the presentation of symptoms, and 67.8% of patients experienced this at the breast clinic. Oftentimes, patients attributed these feelings to being isolated in the clinic and treatment centers, as there were a greater number of FBC patients present. This suggests that men feel especially excluded during chemotherapy and radiation therapy while being treated in a clinic filled with female patients, and designed for FBC. […] This review has identified the main roots of MBC stigmatization to be the lack of awareness among healthcare professionals and the patients own feelings of embarrassment. As such, this stigmatization leads to the creation of barriers for MBC patients when accessing health care. The study by Co et al. interviewed 56 MBC patients and determined that the time between onset of symptoms to diagnosis ranged from 1 to 10 years among participants. The authors also suggested that this is mainly due to feelings of embarrassment experienced by patients during hospitalization, as well as lack of awareness amongst the public.

The incidence of breast cancer in men is rare compared to the incidence in women, with less than 1% of all breast cancers occurring in men. Breast cancer in men is typically identified at a more advanced stage. […] Late-stage diagnosis is due to several issues: Lack of awareness about male breast cancer, Patient procrastination in seeking medical care, Male embarrassment about physical changes in the breast or chest areas. When men present with breast cancer, its typically advanced by the time they feel a painless lump under their areola (pigmented area around the nipple) or a lump in their armpit. Yet, men tend to ignore their symptoms, which is due, in part, to a lack of awareness.
