Breast cancer occurs in men and, although it occurs less frequently than in women, deserves special mention as a health condition, important from the perspective of awareness and early detection. The condition is usually associated with women because it arises from breast tissue. However, men have smaller breast tissue where cancer can develop; thus, it may be less common in men, but it still remains a significant health risk. 0.9% of breast cancer cases are due to men's breasts, but it has a meaningful impact on the affected person and their family.
A few ducts and a small pile of glandular tissue form the male breast. They lack the broad lobules found in female breasts. These ducts and glandular tissue are vulnerable to malignant changes that can lead to cancer. In men, breast cancer begins primarily with mutations in the DNA of cells within the breast. Such mutations cause the cells to grow uncontrollably, forming a tumor. These abnormal cells may, over time, spread to different parts of the body, resulting in metastatic disease; such a condition complicates treatment and worsens the prognosis.
The presence of specific genetic mutations in men is the major risk factor for male breast cancer. Men who have a family history of breast cancer have a higher risk of developing the disease. Such a family history can be direct, as in the case of mothers, sisters, or daughters. It is believed that most cases are related to inherited mutations in the BRCA1 and BRCA2 genes, as these mutations also significantly increase the risk of breast cancer in women. Men who have such mutations have a higher risk of developing breast cancer than men who do not. In addition to BRCA mutations, certain other genetic conditions, such as Klinefelter syndrome, are also possibly associated with a greater risk of male breast cancer. That genetic condition causes men to be born with an extra X chromosome and results in increased levels of estrogen, a hormone that promotes breast cancer cell growth.
Hormonal imbalances also contribute to male breast cancer. Small amounts of estrogen in men contribute to the development of breast cancer. Normal levels of estrogen in women in relation to testosterone may not prove to be good for human health as they may increase the risk of breast cancer. Conditions such as obesity, liver disease, or hormone treatment that increases estrogen levels may also increase the risk. For postmenopausal women suffering from prostate cancer and men who are under hormone replacement therapy or are being treated for prostate cancer using methods that alter their testosterone levels, these individuals may be at risk. Chronic liver diseases are responsible for high estrogen levels in men as they impair the liver's function by breaking down estrogen hormones.
Another major contributor to the development of male breast cancer is age. Although the disease can sometimes occur in infants, most male breast cancers are diagnosed in men over the age of 60. This has a clear relationship with the phenomenon of aging, which significantly increases the likelihood of errors in cellular mutations and hormonal imbalances. In addition, exposure to ionizing radiation is constantly increasing the likelihood of developing male breast cancer. Men who took radiation during treatment for Hodgkin's lymphoma will be more likely to develop breast cancer sometime later in life. Radiation damages the DNA of cells in the breast tissue, leading to cancerous changes.
In addition, the exact cause of breast cancer in men has not been fully identified. Similar to the female version, male breast carcinoma is multifactorial; therefore, several causative genetic, environmental and lifestyle factors will be involved in its development. Research on male breast cancer is constantly being conducted. Increased knowledge about breast cancer will help future generations identify the threat and therefore intervene more timely.
The symptoms that men experience due to breast cancer are similar to those seen in women, but sadly, they are rarely diagnosed until the severity of the disease has increased. Painless lumps in the breast tissue usually point to breast cancer in men. These lumps can be very hard and irregularly shaped, although some lumps can be tender or painful. Men are likely to notice changes in the skin over the breast, such as dimpling, redness, or puckering. In another situation, nipple inversion or discharge may occur as a clear warning sign that something is wrong with the breast and perhaps a sign of an underlying malignancy. The above symptoms may be common with other benign conditions such as gynecomastia (non-cancerous growth in the genital breast tissue). This condition is usually ignored or misdiagnosed as early symptoms of male breast cancer. As a result, this leads to a delay in diagnosis and treatment. Thus, awareness and vigilance is essential with regard to any abnormal breast changes or developments, regardless of gender.
This would be a physical examination for normal men when the diagnosis is of male breast cancer. For example, one would feel a lump or mass or some abnormality in the breast tissue. Then, if a lump or mass is felt, imaging tests, such as mammography or ultrasound, can be used to determine the size, shape, and characteristics of the abnormal area. Breast cancer can be detected in both men and women using mammography, which is considered the standard imaging method. However, since there is less breast tissue, it is not as easily applied to men. Also, ultrasound is usually used to obtain additional information regarding the lump. If the above-mentioned imaging tests suspect the presence of cancer, a biopsy is performed which involves taking a tissue sample from the lump for further analysis. Thus, the biopsy allows to interpret whether the cells are malignant or non-malignant and also determines the type of breast cancer, if present.
After the diagnosis of male breast cancer is confirmed, the closest stage of male breast cancer stage that is needed to stage the cancer is the distance to which the male cancer has spread further within the breast and may have also spread to other parts of the body. This is done along with other imaging tests such as CT scans, MRIs, and bone scans, to evaluate whether the cancer has metastasized to the lymph nodes, bones, liver, or elsewhere within the body. The stage of cancer is important in determining the treatment and prognosis for the patient.
These treatments for "male breast cancer" are actually the same as those for women, although depending on the characteristics of the individual case, some treatment changes may be introduced. The surgical treatment option for breast cancer in men is the most commonly used, especially in the early stages. The most common surgical procedure is mastectomy, which refers to the complete removal of breast tissue. Sometimes, it may be a lumpectomy that only cuts out a small portion of the tumor and surrounding tissue. Factors considered in a surgical operation include the size and location of the cancer, the stage of the cancer, and the overall health of the patient.
Radiotherapy given before or after surgery to remove the tumor from any cells that may remain. It is mostly used when the cancer has spread to the lymph nodes or there is a high risk of recurrence. Chemotherapy is also usually explored in the latest stages of breast cancer. Chemotherapy uses vigorous drugs, with adequate doses, to kill or reduce cancer if the cancer has spread. Another option available for treatment is hormone therapy, especially for those cancers that are hormone receptor positive in nature. Hormone therapy involves blocking the effects on cancer cells through estrogen, either reducing their estrogen levels or depriving estrogen of the ability to bind with cancer cells. Others are targeted therapy and immunotherapy, which are also discussed leading treatment modalities targeting specific proteins or genes that are possibly involved in the growth of cancer cells.
So, yes, the prognosis of male breast cancer depends on how advanced the cancer is at the time of diagnosis, the type of breast cancer, as well as the effectiveness of the treatment. Like its female counterpart, early diagnosis and treatment ensures better outcomes. In general, men have lower survival rates than women due to underdiagnosis and late diagnosis of breast cancer. However, early diagnosis and proper treatment can improve the prognosis for many men with breast cancer.
It has severe emotional and psychological effects on men, especially because it is often considered as a women's disease. However, a man may face a lot of confusion, isolation and stigma. Body image is severely one aspect he must sort out as it may involve surgery and a change in appearance. They act as avenues of support, he seeks them mostly from health professionals, family or support groups.
On a final note, although it is rare, male breast cancer presents a critical medical condition that can affect the lives of those suffering from it as its awareness, early detection and treatment are crucial to improving outcomes for men suffering from breast cancer. However, one must understand the risk factors, recognize the symptoms at the appropriate time and visit the necessary medical facilities to ensure the needs of affected men are met and receive proper care and support in their suffering. Although rare, male breast cancer still presents facts to remind us that breast cancer is not just a women's concern and all genders must be vigilant towards their breast health.
