"Prevention is better than cure". Researching and treating diseases is too costly. So it would be better to invest in preventive measure To what extent do you agree?

It is often said that taking precautionary measures in dealing with diseases is a better approach than getting
treatment
after contracting one.
Although
this
adage may be true, not all diseases can be prevented and
therefore
require
treatment
in order to be cured.
This
essay disagrees with
this
statement and will discuss why sometimes diseases cannot be prevented and
hence
research
is necessary to cure them. There are a number of diseases that cannot be prevented through precaution
such
as measles, polio, chicken pox etc.
Moreover
, there are diseases which are genetically linked and people who have defective genes will contract these illnesses at some point of time.
Therefore
, in
such
cases, one has to visit a hospital and get necessary
treatment
in order to get cured.
For instance
, Type 1 diabetes, Alzheimer’s, Parkinson’s disease and certain types of cancers are hereditary and they can only be treated through medication and therapy. Without
research
,
treatment
for non preventable diseases will not be possible.
In addition
to that, there will always be a new disease outbreaks due to the evolution of bacteria and viruses. Recently, many people suffered from Ebola fever that led to the death of patients in severe cases. The causative virus
also
affects the development of the fetus in pregnant women.
Therefore
, we need to actively conduct
research
and arm ourselves to tackle unknown as well as non preventable diseases. To conclude, prevention should be practiced as a precaution to avoid getting sick, but
this
will not help us avoid certain illnesses which require medical intervention.
Hence
,
research
is absolutely required to develop vaccines, medicines and medical procedures to deal with genetically linked diseases and non preventable diseases.
