What is cancer?
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. Stage I - there’s no
involvement of lymph nodes and no spread of the cancer from metastases or its
original site. Stage IV - the advance cancer, with both distant metastases and
lymph node involvement.
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 and may stop us
in continuing our trip. Problem really comes on our way and nobody is exempted.
It only varies in forms and shapes, but all have sizes and dimensions. One of
the biggest problems that we consider is when a crucial situation burdens us - a
matter of life and death. Acquiring the disease or illness which is almost
incurable is a good example. And one this dreadful disease is the big “C”…
Where cancer starts?
All of us carry an approximated 10,000 malignant cells. The immune system defense mechanism will kick this out of the system. The isolation of these malignant cells will turned out into a self motivated cell – cancel cell.
One of the public health problems worldwide is cancer, which is a deadly disease that afflicts people of all ages and races. It varies greatly in cause, symptoms, responses to treatment and possibility of cure.
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.
When cancer starts?
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 estimation that 16 million new cases of cancer will be diagnosed every
year by 2020.
What causes cancer?
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.
