To Know More About The Causes Of Lungs Cancer
Lung cancer produces irregularities to the tissue of the lung organ
. When there is a irregularity in the bodys internal system, the cancer leads to an uncontrolled growth in the cells that eventually forms a build up of tissue called a tumor. The lungs is responsible for taking in the air we breathe and transport it to other parts of the body. During this process, the lungs aids the body to eliminate carbon dioxide from the blood stream and promotes fresh oxygen to circulate throughout the body. There are two category of tumors; malignant and benign, Malignant tumors develop more rapidly, while benign tumors usually take a longer time to developed and can be removed without it expanding to other sections of the body.
Lung cancer is considered as a malignant tumor due to the fact that it starts to grow outward very early on in its development. When cancer growth continues to a certain degree then it becomes capable of metastasizing to other sections of the body to cause further damage. The sites which are more likely to be infected by a lung cancer are the liver, adrenal glands, brain and bone. Metastasizing also more likely to occur easier in the lungs, that are related to other types of cancers that develop in other parts of the body. Lung cancer is recorded as the most common cause of death throughout the world caused by cancer for both sexes. It predominantly affects older persons, the majority of the persons diagnosed with lung cancer are 65 years of age and older, about 3% of lung cancers take place in individuals under the age of 45.
The most popular cause of cancer is cigarettes or tobacco smoking whether first or second hand. Second hand smokers are persons who inhale smoke blown out from other persons who smoke in their environment. Smoking is estimated to be connected to about 90% of all lung cancer cases. The longer a person practices smoking; there is an increased risk of getting lung cancer and even other cancer diseases. Persons who experience second hand smoking or what is called passive smoking are faced with a 24% increase in developing lung cancer when compared to a person who does not live with smokers. There are reportedly about 3,000 lung cancer casualties that occur each year in the United States.Tobacco smoke contains over 4,000 chemical compounds that are cancer related, the main carcinogen in tobacco are nitrosamines and polycyclic aromatic hydrocarbons.
Exposure to a substance known as asbestos is also a leading cause of lung cancer. Asbestos fibers are silicate fibers which when exposed to can follow persons for a lifetime in the lung tissue. Asbestos is either banned or scarcely used in a many countries. Exposure to asbestos paired with smoking also increases the risk of developing an asbestos-related lung cancer over 50 90 times versus a person who doesnt smoke. Other causes of lung cancer are related to exposure to environmental factors like air pollution due to vehicle exhaust, power plants, and extracts of chemicals like radon gas which is a emitted from uranium. Persons with a hereditary record of lung cancer cases are also more likely to develop the disease. Patients who have previously been cured of lung cancer maintain an additive risk of 1 2% per year for developing a second lung cancer.
Lung cancer is normally diagnosed by doing a chest radiograph, a bronchoscopy and/ or a Computed tomography. If irregularities are seen then doctors may continue with screening exams and then determine what course of action should be taken next. Lung Cancer is one of the more difficult cancers to treat. Treatment may decided on based on the state of which the cancer is in at the time of detection. At earlier stages doctors will more likely use chemotherapy or radiation therapy, in other cases infected persons may have to undergo surgery.
