Hello Steemians!
In the Medicine series today we will discuss about the one of the deadliest disease of the past and present, THE CANCER!!!

One Man out of every two Men and
One Woman out of every three Women will have cancer in their lifetime
That's how common the cancer is in our world!

You may have seen by yourself or may have heard from your friends or from news about the cancer patients. Only the person Daignosed with it will know how hard the life becomes living with the cancer. You cant even imagine what will you do when a doctor says sorry, You have a cancer!
have you ever wondered what exactly is a cancer ?? is it that bad as the people say?? Do not worry we will figure it out.

So what is this cancer thing???

To know about the cancer you first should know how our normal body works. our body is made up of organs like heart,lung brain, kidney muscles and so on. and those organs are not more than bunch of cells, but these cells are so organized that they know what their function is! You may say i'm lying but mind that there are about 37.2 Trillion cells are there in A Human body!
Each cell is made of central nucleus surrounded by cytoplasm and the other organelles!
The nucleus contains a genetic material known as chromosome which in turn is made up of nucleic acid known as DNA. And DNA is the the thing which controls all the activity of the cell. The nucleotide sequence of DNA determines how a cell will work.how much can it divide , how big it can become, where in the body it can go, what function it will , and what organ it will make. so organ is a bunch of similar cells doing similar function! Thats how brain does the thinking, heart does the pumping and lung does the breathing!

So upto Now, you know that all the cells of the body are in a strict rule and regulation thanks to the DNA! but what happens in cancer?
THe basic basic pathology lies in the DNA . Due to many factors like Radiation, smoking, some carcinogenic chemicals, and Hereditary There is alteration in Structure of DNA and this in turn will alter the function. DNA no longer can control the cell. you can correlate it with a simple example

" consider LAW of a nation as the DNA and the People of it as the Individual CELL and THE NATION as the Human body.just think what happens when there is no law in a country, when people dont follow law and do whatever they like there will be chaos in the country . There will be nothing like peace, harmony in the people. and at last the most affected thing is the nation"

This is the same case with cancer! Due to the DNA damage there will be abnormal and uncontrolled proliferationof the cell which contains the damaged DNA . This will produce abnormal group of cells , which themselves will not do any function but also alter the function of other normal cells of the organ . this abnormal group of cells is the cancer. a cells requires food for proper functioning , there will be so much proliferation of the Cancerous cells that they will use the whole food supply of the organ and the normal cells which do not get the food will eventually die. Thus the organ, which is now the group of dying cell , will die!
This cancer not only affects one organ but it can also go to other organs through blood and lymph or by direct invasion. and they will do the same thing wherever they go. ultimately All the organs fail to work and person dies!

what makes the cancer so deadly?? is it curable???

How fatal a disease is depends upon two things

1. The effect of disease itself on the body
2. Impact of treatment on the disease

The cancer , disease itself causes mass destruction of normal tissues but it depends on the stage of cancer.In early stage there is not much harm to the body but when cancer spreads to other organs as well it will damage those tissues too thats why it can be fatal.

The treatment available for cancer are of three types

• surgery- cut and remove cancer tissues
• chemotherapy-drugs used for killing cancer cells
• radiotherapy-radiation kills cancer cells
  In early stages ,it can be cut and removed or can be reduced by other means.But when it spreads to the other tissues , it cannot be removed by any means and fatality is the final outcome!

But all cancers are not Uncurable

The cancers which are confined to certain body tissues , which do not spread , and the cancers of early stage are the ones which can be easily cured.
cancers of these are curable

• thyroid
• testis
• prostate
• breast

How can i prevent and control it???
