The Genes
that speed’s up cell divisions are called Oncogenes.
Proto-oncogenes are genes
that normally help cells grows well. When a Proto-oncogene mutates (changes) or
there are too many copies of it, it becomes a "bad" gene that can stay’s on, or activated when
it’s not supposed to be.
When this
happens, the cell grows out of control
and makes more cells that grow out of control. This can lead to
cancer. This bad gene is called an
oncogene.
For example,
Let us take a cell for a car. For a car to work perfectly; there must be a
perfect ways to control how fast it goes.
A Proto-oncogene
normally functions in a way much like that of the car gas pedal. It helps control how and when the cell grows and
divides. An oncogene is like a gas pedal
that’s stuck down, which causes the cell to divide out of control.

Most of the DNA changes linked to
breast cancer are acquired.
This means
that the change takes place in breast
cells during a woman's life rather than having been inherited.
Acquired DNA changes take’s place over time and are located only
in the breast cancer cells, not
in every cell in the body.
Mutated DNA can lead to mutated genes. Some new genes are
formed and take’s control when our cells grow, divides into new cells, and dies.
Changes in these genes are linked to cancer.

Normal breast cells become cancer
because of changes (mutations) in DNA.
DNA is the chemical in each of our cells
that makes up our genes.
Genes gives instructions for how our
cells function.
Some DNA mutations are inherited or passed
to you from your parents. This means that mutations are in every cell
in your body and certain mutations can greatly increase
the risk of certain cancer’s.
They cause
many of the cancers that run in
some families.

Changes
or mutations in DNA can cause normal breast cells to become cancer.
Certain
DNA changes are passed on from parents
(inherited) and can greatly increase the risk for breast cancer(s).
Other lifestyle-related risk
factors, such as what you eat
and how much you exercise and others;
can also increase your chance’s of developing breast cancer(s).
But it’s
not yet known exactly how some of these risk’s factors causes normal cells
to become cancer.
Hormones seem to play a major or vital role’s
in many cases of breast cancer, but how this happens is not fully
understood or known.

If cancer cells have spread to your lymph nodes, there is a higher chance
that the cells could have traveled through the lymph system and spread
(metastasized) to other parts of your body.
The more lymph
nodes with breast cancer cells, the more likely it is that the cancer may be
found in other organs as well. Because of this, finding cancer in one or
more lymph nodes often affects your treatment plan.
Usually, surgery seems to be the best option to
remove one or more lymph nodes that will be needed to know or test whether the
cancer has spread
Still, not all women with cancer cells in
their lymph nodes develop metastases, and some women have no cancer cells in
their lymph nodes, yet later develop metastases.
