What causes cancer? How to prevent it...

 Do you know that in last year around 96 lakhs people worldwide and 8 lakh people in India died due to cancer. 

 According to WHO cancer stands in second position in terms of causes of death worldwide. One more thing, do you know that in all our body the cancer cell is already present. Then why we all do not suffer from cancer? As we hear a lot of things about cancer so many times around us naturally, we tent to have a lot of questions about cancer. like what disease is cancer?

 How it occursand how we can prevent ourselves from it? So if you also wanted to increase your knowledge about cancer, Okay, before knowing the cancer let us know something about our body our whole body is made up of different organs like- heart, liver, kidney and etc and all these organs are made up of small cells so these cells keep on increasing by dividing themselves and take the vacant space left out by the dead cells. So because of this continuous multiplication of these cells that we have grown up to become fit and healthy individual. 

The DNA present inside these cells,guide our cells about what to do and how to do? DNA is a kind of software of our cells which contains the whole bunch of information and when to have a division or no division of our cells, all these are determined by DNA but sometimes due to some mutation or error occurring in DNA a bad/rogue cell is created which we also call cancer cell. These cancer cells don'tdo their work properly and without any necessity they multiply.

 Many such errors happens daily in our body and these rogue cells are created and therefore we say that inside all of us these cancer cells are present. but these rogue cells doesn't get convert into cancer because our body recognises these error sand these errors are fixed in their initial phase. 

But when our body could not stop the growth of these rogue cells then these gather and becomes cancer. As these cancer cells do not do their work and keep growing unnecessarily. and the organs over which it starts to develop the activities of that organ get stalled due to the stop page of the activity of a single organ our whole body comes undertremendous pressure.

 In the initial phase these cancer cells form a cluster by gathering at one place. Which we also call Tumour. and cancer at this stage is called cancer of primary stage. but when these cancer cells spread in the whole body via the blood then this stage is called the cancer of secondary stage and it becomes more difficult to cure a patient at this stage. Cancer can happen in any part of our body. and in the globally the most cases of cancer are of Lung cancer and breast cancer. 

It is true that defect(Mutation) in DNA can come in anytime. But if we do not keep our body healthy then these defects can become more enhanced. Like we can take the example of typing whenever we type with a keyboard the chances of committing a mistake is always there but if we are tired or sleepy or ill then these mistakes become more frequent. Likewise, there are many factors becauseof which changes in our DNA can come and we can suffer from cancer. On the top, comes the use of tobacco and according to WHO,22% of the people dying of cancer, die due to the use of tobacco. 

By the way, if you want to know that what is there in a cigarette because of which we can get cancer. consumption of tobacco, alcohol, bad eating habits with low fruit and vegetable intake and lack of physical activity are counted as the four big causes of cancer. Along with that due to some infection caused by bacteria and viruses one may develop cancer. like HPV or Hepatitis B Virus. Some radiations can be so strongt hat can cause changes in the DNA of our cells. and because of which we can get cancer. One of its biggest example is UV rays. As we grow old the chances ofhaving cancer is also increased because it has been observed that as we grow old the ability to correct the problems inside us decreases. According to data, in the worldaround 30-50% cancer cases can be prevented by rectifying our habits. By the way more than half the diseases occurs because of our unhealthy lifestyle we need pour chemicals inside us,eat unhealthy food and not want to do any exercise but we don't want any disease. And we don't want cancer either. This can't be happening.
