A Clear Understanding About Cancer
I believe that all of us are drivers
of our own vehicles. We are all on a very special and challenging trip called
“life.” As we take our own journeys, we may meet different forms of hardships
and obstacles on the road. Some of these natural phenomenon like stormy weather
that makes the road slippery, or it maybe big and huge rocks on the road that
hinders us in continuing our trip.
Problem
really comes on our way. In fact nobody is exempted. All of are experiencing
it. It only varies in forms and shape, but I believe that all have sixes and
dimensions. And one of the biggest problems that we consider is when we are in
a crucial situation like a matter of death and life. Having a disease or
illness that is almost incurable is a good example. And one these diseases is
the big “C”… or the cancer.
One of
the public health problems worldwide is cancer, which is a deadly disease that
afflicts of all ages and races. It varies greatly in cause, symptoms, responses
to treatment and possibility of cure. But do you know what cancer really is?
Cancer is
a kind of disease characterized by uncontrolled division of cells and the
ability of these cells to invade other tissues, either by direct growth into its
neighbor tissue or by implantation into distant sites by metastasis.
A process
called staging helps in assessing the prognosis and in determining the most
appropriate treatment to the unrestrained growth of cancer cells. It is used by
physicians to describe the extent of spread of a cancer. In this system, cancer
is being classified into four stages. The early stage of cancer is stage I
where in there’s no involvement of lymph nodes and no spread of the cancer from
metastases or its original site. Stage IV is the advance cancer, with
both distant metastases and lymph node involvement.
Cancer,
which is the unrestrained growth and spread of cells, has the ability to affect
almost any tissue of the body. The five most common cancers in the world
include the stomach, lung and colorectal cancer. Among men, lung and
stomach cancer are the most common cancer worldwide while cervical cancer and
breast cancer are the most common types of cancer for women.
The first
year of life is the age of peak incidence of cancer in children. The most
common infant malignancy is leukemia, followed by neuroblastoma, and the central
nervous system cancers. Other common types of cancer in children include
lymphomas, Wilm’s tumor, retinoblastoma, rhabdomyosarcoma, osteosarcoma and
Ewing’s sarcoma. There’s a rising incidence of pediatric cancers like
leukemia.
Every
year, more than 11 million people are diagnosed with cancer and about 77% of all
cases were diagnosed at ages 55 and above. About 25% of all deaths in the USA
and other developed countries are caused by cancer. Annually, 0.5% of the
population is diagnosed with cancer. There’s an estimation that 16 million new
cases of cancer will be diagnosed every year by 2020.
Exposure
to environment factors such as tobacco, smoke, radiation, alcohol and certain
viruses can cause cancer. Some of these can be avoided but the sad fact that
there is no known way to entirely avoid the disease.
Cancer is
just one of the monsters of life. We can minimize the chance of meeting this
monster and deadly disease if we clearly understand it.
