Cancer and The Role Of Your Genetics
In the battle against breast cancer researchers
have looked into two main areas in search of an answer as to
what is causing this disease. One factor they believe can play
an important role is that of genetics. The other is related
to our environment and the increasing levels of toxins that
play a major role in our modern age.
In helping women to keep aware of their personal risk factors,
organizations have listed an individual at a higher risk if
they have a close relative that has had breast cancer. This
could mean a mother, sister, aunt or cousin that is a part
of a family blood line.
There are presently two
genetic markers that indicate a vulnerability
to this illness. They are listed as BRCA1 and BRCA2. These
are clearly designated Breast Cancer Gene 1 and Breast Cancer
Gene 2. As a rule most people have two copies of these genes
in their cells.
Their normal function is to maintain the health of the breast
cells - to keep them developing and to ward against the possibility
of cancer. They do this by producing a protein that, in effect,
controls normal cell growth. However, if these genes have abnormalities
or mutations a vulnerability is created that could open the
door to breast cancer - to allow an abnormal 'growth' to go
unchecked.
The possibility of inheriting an abnormality can come about
even if only one of the parents has it. It is important to
keep in mind however, that for most breast cancers this particular
issue is not the established cause. In fact, it is estimated
that it may only account for ten percent of them.
Without taking a specific test to verify any genetic abnormality
it is possible to assess the probability of its existence if
a person has close blood relatives on either side of the family
that have had breast cancer before the age of fifty, if the
cancer was in both breasts, if there is an instance of one
person having both ovarian and breast cancer, or if a male
member of the family has also suffered from breast cancer.
It is good to note however, that if the genetic disposition
exists, it is possible that the risk of one's children inheriting
it will diminish over time if family members marry with others
who do not carry the abnormal genes.
Again, it is important to bear in mind that even if there
is a genetic vulnerability, it does not necessarily indicate
that a person will get breast cancer. There are many other
factors that will weigh in as well, such as the lifestyle one
leads, the toxicity of the environment and as well the fact
that there are other genes that continue to work to protect
the health of the body.
Whether one decides to pursue genetic testing or not, the
research indicates that most women who get breast cancer do
not come from a family history of it. The knowledge that it
is not a conclusive factor and that there are a number of other
issues involved can give hope that, whatever our personal circumstances
may indicate, there is much we can pursue in the way of preventative
measures.
