Male Breast Cancer   

 

Men have breasts but much smaller than those of women. Although breast cancer in men is rare, it is important for men to know that they are not immune to the tumor, and they can be affected by the disease as well as women. In particular, it is vital for each man to learn to recognize the male breast cancer symptoms and does not neglect to report them to their health care providers.

A type of breast cancer called
ductal carcinoma in situ(DCIS) is the most common type of non-invasive breast cancer,and tends to start in the lining of a milk duct. A man has substantially less risk of suffering from breast cancer than a woman because the cells of his breast ducts are less developed. In the other hand, women have much higher levels risk than men of developing malignant breast tumor the fact men breast cells are not constantly exposed to estrogen, a female hormone recognized as a risk factor for breast cancer development.

Male breast Cancer Incidence 

 

The number of male breast cancer is less than one percent (1%) comparing to women cases. For instance, In the USA and United Kingdom (UK) combined, the number of men diagnosed with breast cancer is estimated at about 2,140 per year, which leads to between 440 to 455 deaths annually.

Genetic Predisposition - Approximately 15% of male breast cancer cases are associated with inherited mutations in the BRCA2 gene.

Radiation Exposure prolonged or regular exposure to radiation, especially the chest, increases the risk of men breast cancer in men.

Certain Diseases: certain medical conditions such as liver cirrhosis and Klinefelter syndrome, which can increases estrogen levels and lower levels of androgens, can be associated with an increased risk of male breast cancer.
