So
far, we have discussed a number of cancer treatment methods, conventional and
novel methods. Each method has its own
advantages and disadvantages. Although
significant progresses have been made in some of them in recent years, it seems
like there is no perfect way to treat cancer at the present time. Why?
Remember that most cancer cells are mutated and transformed
from normal/stem cells through problematic mutations; the problematic mutations
could be only one out of many thousands of mutations. Thus cancer cells are just like
brothers/sisters of normal cells and similar in many ways. This is what makes it so difficult to treat
cancer. In addition, any treatment that contravenes the growth of cancer cells might also affect normal cells, thus resulting
in side effects. Fortunately, modern
technologies in surgery, chemotherapy, and radiotherapy have made significant
progresses in reducing the side effects (i.e., injuries of normal cells).
If there is a perfect way and it’s easy to deal with,
we wouldn’t have many thousands of scientists in the world working day and
night on finding better answers. The way
the world is created by nature, we are going to have a difficult time to find a
perfect way to treat cancer. However,
researchers are making progress inch by inch; newer and better methods have
been developed in the last 50 years or so and there will be more and more
improvements discovered in the coming years to fight against cancer.
In my opinion, stem cell related therapies have the
best chance to be among the best methods for treating cancer. Among them, two strategies are most appealing
to me; they are (1) potential treatment by exosomes, and (2) reversing cancer
cells back to normal cells. However, a
lot of technical hurdles must be overcome before either can become
practical. In any case, I believe this
is an exciting period of time for the research and development of cancer
treatment. We are also putting some of our efforts in this general area and
hope to make some contributions.
