Lungs cancer is one of cancer which occurs both in men and women worldwide. As per many cases, cigarette smoking is the main cause of Lung cancer, Another risk factor for the development of the Lung cancer is due to passive smoking which is passive exposure to tobacco smoke is also the main reason for the development of the lungs cancer. There are two types of lung cancers such as small cell lung cancers (SCLC) and non-small cell lung cancers (NSCLC). To know about the stages of the lung cancer in a patient, based on the extent which cancer has extended in the body.
The human body is made up of trillions of living cells. The normal human body cells grow, divide into new cells and die in a particular way. During the early days of any person’s body, the normal cells divide faster which helps to allow the person to grow. After that person becomes adult then mostly the cells divide only to replace the dying cells or it helps to repair the injuries. The main reason for cancer attacking in a human body, the time when the cells start to grow out of control. There are different types of cancers, but the main reason of causing cancer is because of out-of-control growth of all the abnormal cells. The Cancer cell growth in a human body is different from normal cell growth.
Types of Lung Cancer
Lung Cancer Stages are considered, based on the extent which cancer has extended in the body. Lung cancer treatment contains surgery, chemotherapy, targeted therapy, immunotherapy, and radiation therapy. Also by implementing newer experimental methods, treatments are providing to cure the lung cancer patients. Diagnosing the lung cancer in the early stage is very difficult, the doctor also tends not to find the tumor is developed an advanced stage. The five-year survival is around 54% for the early stage of lung cancer, the cessation of cigarette smoking is the development of the lung cancer which is localized to the lungs.
- Non-small cell lung cancer
- Small cell lung cancer
Lung tumor tends to expand and spread very quickly after it forms, Lung cancer can easily spread to any organ in the patient’s body, There are various locations or organs which cancer can easily spread such organs are mainly adrenal glands, liver, brain, and bones. The process of spread has another term which is a metastasis. The lung tumor is common cancer for metastasis from malignant tumors in various organs of the patient. As the original or primary tumor, the tumor metastasis is developed under the similar types of cells.
The basic functioning of the lungs is to exchange gases between the air we breathe and the blood. Here, oxygen enters the bloodstream of our body and carbon dioxide is removed through our lungs. We have two lungs, the right one has 3 lobes and the left lung classifieds into two lobes, the small structure is called as lingula which is equal to the right of the middle lobe. Through a thin layer tissue, lungs and chest wall are covered, the thin layer of tissue is also called as pleura.
Lung Cancer Stages
Lungs cancer can be developed in any part of the lung organ, As per many studies, 95% of the cancer cases of the lung are proved that Lungs cancer is formed from the epithelial cells, the cells which are lining both small and large airways which are bronchi and bronchioles. This is the main reason, lung cancer is also referred as bronchogenic cancers or bronchogenic carcinomas. Cancer has another term which is carcinomas, tumors can also be developed from the mesotheliomas which are also referred as pleura.
Lung Cancer Causes
Lung cancer is very difficult to diagnose the in its early stage. Below are the common causes of lung cancer. cigarette smoking is the main cause of Lung cancer, Another risk factor for the development of the Lung cancer is due to passive smoking which is passive exposure to tobacco smoke is also the main reason for the development of the lung cancer.
What causes lung cancer
Cigarette Smoking – Tobacco:
The lung cancer is strongly caused by the smoking, nearly 90% of lung cancer cases are arises due to the result of tobacco usage. Lung cancer increases with the number of smoked cigarettes, Per day, among those who smoke more than two packs of cigarettes. Pipe and cigar smoking also arises the lung cancer. If you have a smoking habit, quit it and go with nicotine gum, nicotine sprays, or nicotine inhalers, which are very helpful to individuals trying to quit smoking.
Exposure to Asbestos fibers:
Asbestos fibers are silicate fibers which can persist in a tissue of lung, In many countries, asbestos is banned in many countries. Smoking is one of the habits which can highly arise the chance of an asbestos which relates lung tumor in workers who are exposed more to asbestos. The Asbestos workers those who don’t smoke have a fivefold greater risk of arising lung cancer than non-smokers.
Exposure to Radon Gas:
Radon gas is the natural gas radioactive which is a natural decay product of the uranium which emits the radiation ionization. This gas is odorless and also invisible, Radon gas is also drastically arising the lung cancer, as per survey 20% of lung cancer patients deaths are caused due to this Radon gas in united states. In U.S, After smoking, Radon gas is the second leading cause of lung cancer.
By Considering many studies, the lung cancer is more likely to occur in both smokers and nonsmokers. Due to Cigarette smoking, smokers occurs lung cancer and Non-smoking relatives of those who have had lung cancer, due to individual genetic susceptibility, may play a role in the causation of lungs cancer. Due to inheritance certain genes which is DNA repair also plays a major role for arises of lung cancer.
The pollution which arises from vehicles, industry and also power plants can raise the lungs cancer in every exposed person. 1%-2% of lung cancers are causing due to air pollution. As per the cancer experts words, they believe that individuals, those who exposed more to highly polluted air they can have more chances to occur a lungs cancer.
Exposure to diesel exhaust
Under the studies of workers, the exposed to diesel exhaust is also arises the lung cancer in the human body, diesel engines are made up of gases. Many individuals those who comes under truck drivers, toll booth workers, forklift and other heavy machinery operators, railroad and dock workers, miners, garage workers and mechanics, and some farm workers are more exposed to diesel exhaust, which is very dangerous to health and also have more risk factor of arising the lung cancer.
Lung Cancer Symptoms
It is very difficult to diagnose the lung cancer in its early stage. Below are the common signs of the lung cancer in a person. it is very difficult to diagnose the lung cancer in early stage. Following are the common signs and symptoms of lung cancer. If you have any of these symptoms and don’t neglect to consult a doctor.
- A cough which is very new persistent or a chronic cough which is worse
- Blood in the sputum,
- persistent bronchitis or repeated respiratory infections,
- chest pain,
- Drastic weight loss and/or fatigue,
- Facing difficulty while breathing
- shortness of breath or wheezing.
Lung Cancer Treatment
For lung cancer, doctors give various treatments which include surgery, radiation therapy, and chemotherapy. For some types of lung cancer, they provide targeted therapy which uses the material that attacks the cancer cells which are affected without affecting the normal cells. To prevent lungs cancer, avoid smoking and eliminating exposure to tobacco smoke is the most important. If you have a smoking habit, quit it and go with nicotine gum, nicotine sprays, or nicotine inhalers, which are very helpful to individuals trying to quit smoking. Avoid tobacco and be healthy and happy.
