It’s far more important to know what person the disease has than what disease the
person has. – Hippocrates
Human beings are born heterogeneous in genomic level with no two persons having
identical DNAs. Even identical twins do not have the same DNA. No two human are
alike and thus “one-size-fits-all” approach to medicine is not acceptable.
Moreover, the DNA that we inherit in our birth changes over time depending on
the food we eat, the surrounding environment and our lifestyle. Accordingly, we
respond differently to the diseases we get and also to the treatment regimens.
Thus it is reasonable to say that every disease should be treated differently in
different individual and should be tailored according to their genetic makeup
for best outcome.
Our body that is constructed with cells, muscles, nerves and organs is coded in
the genes. Genes possess genetic blueprints for each and every part of our body
and also shows the diseases liable to attack us. In the past several years,
several scientific advances have come into focus and the revolution in human
genetics is the results of one of such advances. The revolution in human
genetics led to improvement in all specialties of medicine. One of them is the
recognition that the genetic composition of an individual can be used
effectively while treating a patient. The second one is the availability of the
human genome sequence and the improvement in technologies. The third impact of
scientific advances is the ability to utilize the human genome practically while
treating the patients at a very low cost.
The personalized medicine presents the most effective medical treatment that is
much ahead of the regular treatments offered by the physicians by “the use of
genomic, epigenomic exposure and other data to define individual patterns of
disease, potentially leading to better individual treatment.”
In the long run, personalized medicine will eventually reduce disease burden and
the treatment can be done more effectively. It will also reduce healthcare costs
as medical diagnostics and therapeutics can be selectively tuned to meet the
needs of individual patient.
