Smoking
I do not want to scare, persuade or save anybody. The following information is based on pure medical facts. These facts are not manipulated by no one’s belief, habit or permission. Smoking has an effect on the human body. I will list some of the consequences, that most of the smokers must face it.
Lung tumour
It is the causer of cancer and usually the tumour causes a large number of death. In 70% of women and in 90% of men the tumour is caused by smoking. These tumours usually appear in the respiratory tracts and in the bronchia.

Symptoms
The most obvious symptom of the tumour is long and endless coughing. If the tumour gets to the blood vessels, the coughing regularly comes with a scary ammount of blood and unfortunately the tumour can press the oseophagus if it is developping in the given area.
Sometimes it can turn into a pneumonia, which goes with high temperature and pains in the chest. Later the patient loses hunger, weakens and the labouring breath increases.
This lung tumour can spread over in the body and if it hits some nerve running to the brain, that can cause torpidity around the eyes and on the face. It can spread to the oseophagus, which makes swallowing more difficult and painful. If it reaches the heart, then it causes heart beat disorders or it can cause grown heart. The tumour can reach the liver, the brain and the bones through the blood circulation. This can happen in the beginning stage of the disease.

How to identify?
The suspicion of the tumour rises, when the patients cough of a lot and they condition worsen. Smoking makes the suspicion more determined. Shadows on the x-ray can be suspicious even if the patient is quite all right.
If there is a chance, that the shadow is caused by a tumour, then it must be examined. You can give a sample by cough up some phlegm, or with a short operation. It is important to make sure that there are no other affected parts and to do this you need some more examination and you have to give some tissue sample.
