- Preimplantation Genetic Diagnosis -
Preimplantantion Genetic Diagnosis can also be offered
for prevention of cancer in families with a history of a determined
The exact cause of Cancer is unknown. Men or women with familial history
of a determined Cancer are at an increased risk, lending support to a
belief that Cancer may be hereditary in some cases. Some cases of Cancer
have been traced to genetic abnormalities. For example, we can look at
breast cancer. Those without the genetic background and genetic line
have a risk of 2% to 10% of developing breast cancer depending on age.
On the other hand, those with a definite genetic line face a higher
danger, up to 70%, of developing cancer of the breast.
In cancers that are more prevalent in one gender than the other, for
example as in the case of Prostate Cancer, where it exclusively occurs
among males, P.G.D will reduce the chances of having an affected child.
The Preimplantation Genetic Diagnosis can find the gender of the embryo
prior to implantation inside the uterus. Using P.G.D to implant only
female embryos will ensure the couple with a strong family history of
this disease that their child will not be affected with Prostate Cancer.
Couples should consult with a genetic counselor about their actions.
P.G.D can currently test for a variety of diseases, inclusive of
X-linked diseases, and those that primarily affect a specific gender.
P.G.D is continuously being improved so we may be able to test for more
and more genetic disorders in the near future.
