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.
The White Part
The major cause of lung cancer is strongly correlated with smoking cigarettes. Pipe and cigar also causes cancer. An increased risk of developing lung cancer is passive smoking, the inhalation of tobacco smoke from other smokers. Exposure to asbestos fibers is linked to lung cancer. Air pollution can increase the likelihood of developing lung cancer. And genetics also plays a part.
The most damaging part of cigarette smoke is what we usually call tar, but which technically consists of polycyclic aromatic hydrocarbons.
lung and liver. it causes cancer. also kidney. heart. But mostly Lungs.
Tobacco tar is the sticky, black component of cigarette smoke. It is part of what causes lung problems from smoking. The nicotine is what is addictive, but the tar and other chemicals in the smoke are what cause most of the health risks.
no, it means colapsing of of part of the lung.
A lobectomy is the removal of one lobe of the lung. If the cancer is limited to one part of the lung, the surgeon will perform a lobectomy.
the smoke because it gets into your lungs and it starts to infect it with all different kids of chemicals.
I think its the tar in the cigarette that causes irritation in the bronchioles and therefore cause bronchitis...
This procedure involves removing a small part of the lung.
If it gets into your blood, theoretically any part.
tar causes of perhaps all diseases in the lungs
You are part of the society! It can affect people by many things. For example, your friend has lung cancer, doesn't that affect you if your friend dies? It should! And, if people smoke you can get lung cancer, and if you are in the same room, you are second hand smoking!
the answer to that question depends on what part of the cancer victims lob? its alot because my grandmother just went threw it and i estimated $12,000 - $100,000 for a lung cancer surgery
Cervical cancer is cancer that starts in the cervix, the lower part of the uterus (womb). Eventually it affects your whole body including your lung.
A part of his left lung
theres100 different chemicals in your cigarettes,out of 100 which is 52 chemicals which causes cancer tar you can imagine the rest ******** The honest answer is that they have no idea, just as they have no idea which chemicals in the food we eat, the 'fresh air' we breathe, the water we drink or the radiation from the sun, mobile phones, etc. cause not only lung cancer but all types of cancer. They can make an guess from results of epidemiological studies and tests on mice, rats, dogs (try Googling "Beagles Lung Cancer" to see the barbaric cruelty they inflicted to attempt to prove the link between smoking and lung cancer), monkeys, pigs, etc. A list of carginogens is maintained by IARC (part of the WHO). It includes solar radiation (sunshine), Talcum powder, Vitamin K, caffeine and mobile phones!
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.
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.

it can affect it in loads of different ways such as pain in body part
lung cancer can start from any part of the lungs and may affect any part of the respiratory system... it can cause breathing and heart problems such as 1] pleural efflusion, which is the build up of flud between the outer lining of the lungs and the chest wall.. this is the common condition with lung cancer. 2] coughing up large amounts of bloody sputum 3]collapse of lung [pneumothorax] 4]blockage of the air way [bronchial obstuction] 5]recurrent nfection such as pneumonia 6]precardial effusion which is the buildup of the fluid in the space between the heart and the pericardium[i.e. the sac present around the heart]... this condition is not too common in lung cancer... as lung cancer grows it may spread to other parts of the body.... lung cancer is classified in stages, which describes how far the cancer has grown and spread... the long term outcome of lung cancer depends onhow much the cancer has grown or spread..
because a PART of our body gets rotten then it causes us cancer.
While it's hard to determine exactly what's in tar, it's clear that it causes most of the bad health effects of tobacco: Cancer.
