Understanding Breast cancer at the cellular level gives us greater opportunities for treatment development as well as a better insight to what is actually happening in the body when afflicted with breast cancer.
It all starts with an alteration to the genetic code of the DNA of the breast cell. This change in the original code is referred to as a mutation. Mutations may occur randomly or they may be caused by substances called mutagens. There are an assortment of different factors that may contribute to the occurrence of mutations other than the errors that happen spontaneously.
Environmental and chemical influences are two more common other factors. DNA interacts with the environment constantly, and at times these interactions can effect the DNA in a negative manner. For example, the ultraviolet light rays given off by the sun may react with a person’s DNA and cause mutations to occur in his or her skin cells that may subsequently lead to skin cancer. In the case of breast cancer, ionizing radiation such as cosmic rays, gamma rays,
