Through gene therapy this is a very real possibility. In the future it could be just as easy to change your physical or mental health as it is to get flu shot now. But the affects of gene therapy are long lasting and could affect your future offspring as well as your own health. During the 1980's the term gene therapy came about and propelled research further. When one of those genes has a mutation or flaw in the DNA structure it can lead to disease.
Some diseases related to genetic inheritance are diabetes, sickle cell anemia, and some cancers.
With gene therapy we can eliminate these diseases before they even show their fist symptom. There are two types of gene therapy treatments. They differ in the consequences they have for the patients. The first is somatic cell gene therapy. In this process faulty genes are replaced by the correct sequence of genes.
