The Nicotine and the Tar

Nicotine does not directly cause cancer, but is instead the addictive compound recognized by nicotinic receptors. While nicotine is not mutagenic, the addiction created by the bodies craving for results in the uptake of carninogens. Tar is a generalized term for any substance that coats. In this case Tar is a residue formed by the burning of tobacco. Tar coats the alveoli of lungs, thereby decreasing air exchange and contains several mutagens.

Benzo(a)pyrene [B(a)P] diolepoxide (BPDE) is the substance found in cigarette smoke which causes mutations in the P53 gene. P53 is one of the "gatekeepers" of the genome and if mutations occur that affect its function, the cell can lose proofreading ability during replication thereby allowing cancerous cells to form. BPDE is formed by the burning of tobacco (heat activated), and is also found when wood is burned, or steaks are overcooked.

Understanding Lung Cancer Tumors?

Malignant lung tumors can grow quickly and spread to other organs of the body. Lung cancer has the highest chance of being successfully treated when a patient is diagnosed in the early stages. Individuals with risk factors should understand the symptoms of lung cancer tumors.Causes of Lung CancerMajority of lung cancer cases result from individuals who smoke tobacco for a long period of time. The more cigarettes and the longer a person smokes increase the risk of developing lung cancer. Smoking cigars and pipes can also contribute to the development of lung cancer, although the risk is not as high as with cigarettes. The chemicals in tobacco lead to the mutation of cells within the lungs. As the cells reproduce, a person develops lung cancer. Non-smoking individuals who live around second-hand smoke are also at risk of developing lung cancer.Symptoms of Lung CancerApproximately one-fourth of individuals with lung cancer do not experience any symptoms. In many cases, lung cancer is discovered during a routine X-ray of the chest. A patients that does not experience symptoms usually has a small, solitary lung tumor. As lung cancer grows, tumors can start to invade the lungs and cause symptoms. Lung cancer tumors may cause shortness of breath, chest pain, vocal cord paralysis, and coughing up blood. In some patients, lung cancer can spread to the bone and cause extreme pain. Cancer can also spread to the brain and affect an individual's vision and cause headaches and seizures.Staging and TreatmentsStaging refers to how much lung cancer cells have spread to other parts of the body. The stage of an individual's lung cancer determines how the doctor will treat the cancer. Lung cancer stages range from stage I to stage IV. Stage I lung cancer, which means the tumor is only located in the lung, may be treated with surgery to remove the tumor. Radiation therapy is used to kill cancer cells and prevent them from dividing, and to shrink tumors so that surgery can be performed. Individuals with advanced lung cancer typically undergo chemotherapy, which is used to kill rapidly dividing cancer cells. The unfortunate part of chemotherapy is that it also kills normal cells. Chemotherapy can compromise a person's immune system.

How is lung cancer caught?

Lung cancer or any cancer among humans is not "caught". With the exception of three varieties (Devil facial tumour disease (DFTD) is an aggressive non-viral transmissible parasitic cancer - which likely originated in Schwann cells - that affects Tasmanian Devils and other types found in dogs and Syrian hamsters) cancer is not contagious and there are an incredible array of causes for just lung cancer let alone all cancer. However, some risk factors for lung cancer is smoking, asbestos exposure, genetics,.... many many more. The best things you can do to lower your risk for lung cancer is to never smoke, avoid dusts like asbestos, don't be a fireman (smoke exposure) and take similar precautions. However your risk for any cancer for any part of the body can never be zero.
