Modifications or mutations in DNA can lead to the cancer of healthy breast cells. Different DNA modifications are (inherited) passed by ancestors and can be considered accomplished to increase your risk for breast cancer.
Additional risk factors related to lifestyle. Just as much as you eat and exercise, your chances of breast cancer can increase.
Nonetheless, it still does not understand how certain risk factors could lead to cancer in healthy cells. In many forms of breast cancer, hormones appear to play a part, but it is not fully understood why they occur.
Inherited versus acquired DNA mutations
Because of changes (mutations) in DNA, healthy breast cells become Cancerous. The chemical composition of our genes in our cells is DNA. Genes have instructions on how our cells work. Certain DNA changes in your parents are inherited or passed on to you. This means that when you are born, mutations are present in your cells, and some changes can increase the risk of certain cancers significantly. They cause many diseases in certain families and often cancer in younger people
Proto-oncogenes are genes that help cells usually grow. When a proto-oncogene
There are too many copies (changes) or mutates. It turns into a “bad” gene, that can remain on or on if not activated. When this occurs, the cell grows out of control and produces more cells out of control. The result may be cancer. This wrong gene is known as an oncogene.
Consider a cell like a car. If the car is to operate properly, it must be controlled as quickly as possible. Typically, a proto-oncogene is similar to a gas pedal. It helps to control the growth and division of cells. An oncogene is like a stuck gas pedal that causes the battery to disintegrate.
Tumor suppression genes
The tumor suppressor genes are common genes that are called apoptosis or programmed cell death, slow down the cell divide (cell growth), repair DNA error, and tell cells when to die. If tumor-suppressor genes are not working properly, cells can grow out of control, produce more cells out of control, and die when needed, leading to cancer.
