C
ancer is a disease that will most likely affect each and every
one of us throughout our lives. There are approximately 560,000
people that die from cancer each year. To put it in perspective,
between 1/4 and 1/3 of all Americans will die from this deadly
disease. These statistics could be greatly reduced if people
would stop smoking. Approximately 35% of all cancer cases are
direct results of tobacco use.
Many people do not fully understand what cancer really is. Cancer
is simply a mutation in the cells which causes them to replicate
continuously without bond. Many people relate cancer
with tumors, and
rightly so. A tumor is basically just a lump of mutated cells
which eventually grows so big that it blocks the functions of the
organs around it (a benign tumor) or begins to invade tissues
surrounding it (a malignant tumor).
Although there has been extensive research concerning cancer,
nothing has been found that can cure cancer 100%. The reason for
this is because a cancer tumor carries many different cancer
cells. Every cancer cell reacts differently to each method of
treatment, so while chemotherapy may kill some cancer cells in
a tumor, other "subpopulations" of cells in the same tumor may
not be affected at all. Another problem with cancer is
that the cancer cells are able to travel throughout the body,
an event known as metastasis.
This means that cancer cells in the breast or lung are able to
travel to the heart. This means that the cancer can spread
throughout the body very easily, making treatment very difficult.
While we have no true cures for cancer, there have been a few
methods of treatment that have been somewhat successful. One such
treatment is the drug cyclophosphamide (which is actually
converted to 4-hydroperoxycyclophosphamide, or 4-HC,
in vivo by the liver).
The use of this drug has been shown to be up to
33% effective in the treatment of cancer, making it one of the
most valuable weapons that we have. Cancer research will
inevitably continue as long as there is a need for treatment.
Hopefully someday we will find a cure.
We found the following cancer links very informative:
http://www.arc.com/cancernet/cancernet.html
- provides further information on cancer including links to
clinical information, support and pevention, and a cancer fact
sheet
http://www.nci.nih.gov
- this is the link to the national cancer institute, a division of
the national health institute, a government funded health
project. It contains information about current cancer research
and general information for public awareness.
