How Cigarette Smoke Causes Cancer


Published on

Guns kill, bombs kill, Smoking kill. It causes many types of cancers, including lung cancers, stomach cancers, larynx cancers, esophagus, mouth cancers, throat cancers and bladder cancers. But not all cancers end in death. It can mean debilitation which is a high price to pay for smoking.

How Cigarette Smoke Causes Cancer

  2. 2. It is well known that people who smoke are ten times more likely to die from: larynx cancers Pharynx cancers stomach cancers mouth cancers lung cancers and chronic obstructive lung disease, including emphysema and esophagus. These risks are higher when smoking is combined with alcohol or long-term exposure to certain types of toxic substances like asbestos.
  3. 3. Lung cancer • Suffering from this kind of cancer begins with a cough. It can be persistent or bloody. A smoker experiences shortness of breath, pain and discomfort. Mouth cancer • • Cigarette smoking is one of the leading causes of mouth cancer. It begins with a change of DNA structure known as mutation, this alters the instructions that controls the growth of cells. It then spreads out of the mouth and into the nearby tissues. At first it appears as a painless lesion but it becomes painful when the tumor grows. Swallowing may be difficult, and foods may taste different.
  4. 4. Larynx and Pharynx Cancers • The larynx and pharynx are close to each other in the neck. Larynx and pharynx cancers (throat cancer) begins by hoarseness, earache, and difficulty swallowing. • The cells used for breathing, speaking, and swallowing begins to divide rapidly and abnormally. It also affects parts of the tongue, tonsils and trachea.
  5. 5. Esophageal Cancer • This is a cancer of the oesophagus. The esophagus is used to carry food from the mouth to the stomach. It is a serious type of cancer that affects the oesophagus and most people do not live 12 months after symptoms first appear. Symptoms are; swallowing difficulties, loss of appetite or weight loss. In most cases the cancer is not recognized until it is too late. Bladder Cancer • • • Smoking can also cause bladder cancer. The bladder which stores urine. This is an uncontrolled growth of cells that make up the lining of the bladder. It involves painful urination, frequent and bloody urination.
  6. 6. How Cigarette Smoke Causes Cancer • Before smoke causes cancer, there are other multiple smoking effects you must experience including coughing, Stained teeth, Yellow fingers, Shortness of breath, blood circulation problems, Grey complexion, Lack of energy, Dry mouth, Dizzy spells, poor taste, tobacco smelling etc.
  7. 7. What is in cigarette smoke anyway? • Cigarette smoke contains thousands of ingredients that causes cancers, they include – – – – – – – – – – – – – – – – – Ammonia, (a poisonous gas), Levulinic acid (used in cleaning solvents) Urea (a compound found in urine) Diammonium phosphate (a compound used to make fertilizer) Formaldehyde (a chemical used in building materials household products) Chocolate, that is used to make cigarettes taste bitter. Tar (a mixture of dangerous chemicals) Arsenic (used in wood preservatives0 Benzene (an industrial solvent, refined from crude oil) Cadmium (used in batteries) Formaldehyde (used in mortuaries and paint manufacturing) Polonium (a highly radioactive element) Chromium (used to manufacture dye, paints and alloys) 1,3-Butadiene (used in manufacturing rubber) Polycyclic aromatic hydrocarbons (a group of dangerous DNA-damaging chemicals) Nitrosamines (another group of DNA-damaging chemicals) Acrolein (formerly used as a chemical weapon) Just to mention a few.
  8. 8. • Although it may look harmless enough – tobacco releases dangerous mixtures of about 4,000 chemicals when burned: – More than 70 of these chemicals causes cancer. – There are hundreds of different other poisons. – Nicotine itself is a highly addictive drug, and many additives are designed to keep smokers hooked.
  9. 9. What exactly causes cancer in cigarette smoking • Once Nicotine enters in the body, a smoker becomes addicted to it. Then the other cigarette ingredients are what causes cancer. The cancer causing ingredients contains thousands of chemicals and around 70 of those chemicals are cancerous. All which are deadly.
  10. 10. Tar • Tar is a mixture of dangerous chemicals. It is obtained from • numerous organic materials such as coal, wood, petroleum, peat etc It is the main agent that causes cancer in cigarette smoke. Some of the chemicals found in tar are: • • • causes your lungs to be dirty and unable to expand and contract as you breath making them useless. Tar is a substance that causes tumors in the tiny sacs of your lungs. These tumors can grow over time, expand and take over your system. Emphysema is when your lungs are unable to bring oxygen to your blood and your body ultimately dies, as your heart, brain and entire body needs oxygen to live, but all of your sacs are dirty and long time dead. It
  11. 11. Benzene • Benzene can cause cancer, particularly leukaemia. The link between benzene and cancer has largely focused on leukemia and cancers of other blood cells and Many leukemia deaths are caused by smoking. Cadmium • Studies have found that the amounts of cadmium present in tobacco smoke are capable of affecting our health. It is a known cause of cancer, and can also damage the kidneys and the linings of the arteries.
  12. 12. Formaldehyde • A smelly chemical used to kill bacteria and preserve dead bodies as well as manufacturing other chemicals, is one of the substances in tobacco smoke most likely to cause cancer and other diseases in our lungs. Polonium – 210 • • This is a radioactive element that strongly emits a very damaging type of radiation called alpha-radiation that can usually be blocked by thin layers of skin. But tobacco smoke contains traces of this polonium, which become deposited inside their airways and deliver radiation directly to surrounding cells, causing cancer.
  13. 13. Nitrosamines • Nitrosamines are very strong cancercausing chemicals found in tobacco products that damages DNA. Even though they are found in relatively small amounts in cigarettes, they are extremely strong chemicals that causes cancers.
  14. 14. Acrolein • Acrolein can also damage the DNA that is similar to the damage seen in lung cancer patients. – Smoke contains up to 1,000 times more acrolein than other DNAdamaging chemicals, this makes it a major cause of lung cancer. Carbon monoxide • Carbon monoxide does not cause cancer directly but it makes it easier for other chemicals to do so. – It hinders the lung’s ability to clear away toxins and sticks to red blood cells in the place of oxygen.
  15. 15. Conclusion Don’t smoke. Or if you do, be ready for any cancer death. It is found out that smoking currently causes 87 percent of lung cancer deaths. Even those who do not smoke directly, but inhale secondhand smoke, are affected by lung cancer. Apart from tobacco ingestion, smoking has other toxic poisons that leads to cancer. Cigarette smoke exposes the tissue cells of the lungs to the host of cancer causing substances contained in the smoke called “Carcinogens”. This also affects DNA, making the lung cells to be cancerous.
