Ovarian cancer is one of the leading causes of cancer death
in women. It has been fairly long known that the genes we inherit from our
parents affect the chances of somebody getting ovarian cancer, but new research
has shown that there are 12 new genetic variants that have been found
associated with the risk of this kind of cancer. The study included about
450,000 samples, and they were looking to identify the genetic background for
the most common cancers. A novel genotyping technique was used and allowed the
researchers to identify almost 500,000 single nucleotide polymorphisms. According to this study, a woman’s genes are responsible for 1/3 of her risk of developing ovarian cancer.
Reading this article hit home for me because ovarian cancer runs in my family. Knowing that my genetic makeup accounts for 1/3 of my risk of developing this cancer definitely makes me a little uneasy. Luckily, this research also showed that there are ways to reduce my chances (like being on an
oral contraceptive), so at least I know that there are things I can do to
decrease my risk. Now that this data has been published, I think it would be a
good idea for primary care physicians and OB/GYN’s to strongly encourage women
who come from a family history of ovarian cancer to be screened very early on,
and to be offered/suggested ways to decrease her chances of developing it.
It is amazing that our genes hold such a high chance for us to get cancer. It is a scary thought that even though you lived a very health conscious life and did everything you could to reduce your risk, but the gene could still be in us and there is nothing we can do to avoid it.
