Breast cancer is caused by cellular changes that are affected by two theories. The first theory is related to stem cells. The cells, which are created from birth and placed in the breast, under the effects of environmental factors, turn to cancerous cells in a period that can range from young to old. In this theory, one can imagine that if all the women of the world live forever, they eventually infected with this cancer. The second theory is the theory of gene mutation that is in fact the natural cells of every organ, such as the breast, are affected by the environmental factors and turn to cancerous cells. However, each of these two theories of breast cancer is known to be a gene-related disease that is caused by disorders that occur in the cell's gene, while this cancer is not at all genetic-related, and just up to 7% of breast cancer cases are considered as the genetic diseases. It means that parents have a specific gene for cancer and transmit it. Breast cancer is one of the most commonly diagnosed diseases in women, and knowing the basic information in this regard for any woman, although not infectious, is necessary because of the prevalence and importance of the disease.
