Lung Presentation

  2. 2. Information on Cancer Cancer of the lung results from an abnormality in the body’s basic unit of life, the cell. The body maintains a system of checks and balances on cell growth so that cells divide to produce new cells only when needed. If the system of checks and balances is interrupted, the cell growth results in an uncontrolled division of cells that eventually forms a mass known as a tumor. Lung cancer tends to spread very early in its course, causing it to be a very life threatening cancer and one of the most difficult cancers to care for and treat. Lung cancer can spread to any organ in the body, in particular, the adrenal glands, liver, brain, and bone. Lung cancer mostly occurs in the lungs of elderly people. Lung cancer was not common prior to the 1930s but increased dramatically over the following decades as tobacco smoking increased. In many developing countries, the incidence of lung cancer is beginning to fall following public education about the dangers of cigarette smoking and effective smoking-cessation programs. Nevertheless, lung cancer remains among the most common types of cancers in both men and women worldwide.
  3. 3. STATISTICS Lung cancer usually occurs in the lungs of the elderly; almost 70% of people diagnosed with the condition are over 65 years of age, while less than 3% of cases occur in people under age 45. 7

  5. 5. Symptoms of Lung Cancer Symptoms of lung cancer are varied dependent upon the exact location of the tumor and the extent of its spread. A person with lung cancer may have the following kinds of symptoms: No symptoms - Up to 25% of people who get lung cancer do not have any symptoms when the cancer is found. Symptoms related to the cancer - The growth of the cancer and invasion of lung tissues and surroundings may interfere with breathing, leading to symptoms such as cough, shortness of breath, wheezing, chest pain, and coughing up blood. If the cancer has invaded nerves, for example, it may cause shoulder pain that travels down the outside of the arm or paralysis of the vocal cords leading to hoarseness. Invasion of the esophagus may lead to difficulty swallowing. Lung cancer can spread to the bones and cause pain. It can also spread to the brain causing headaches, blurred visions, seizures, or symptoms of stroke. Lastly, there are symptoms such as weight loss and weakness.
  6. 6. Treatments for Lung Cancer A cancer specialist looks at a number of factors that help them plan the treatment. They look at the type of lung cancer you have, where the cancer is within the lung, ones general health, whether the cancer has spread, and results of blood tests and scans. Different people get different treatments depending on certain factors. Small cell lung cancer is mostly treated with chemotherapy. Surgery is only suitable if there is no sign that the cancer has spread to the nearby lymph glands and this is rare with small cell lung cancer. It has usually spread at the time of diagnosis. So chemotherapy is usually the main treatment. Non small cell lung cancer can be treated with surgery, chemotherapy, radiotherapy or a combination of these, depending on the stage when the cancer is diagnosed. If a person is on stage one of the lung cancer, the most common treatment is surgery. If they are on stage two, the most common treatment is surgery, chemotherapy, or radiation. If one is on stage three A, then the most common treatment is combined chemotherapy and radiation, and sometimes surgery based on results of treatment . On stage three B, it is chemotherapy, and sometimes radiation. For stage four, the most common and recommended surgery are either chemotherapy, targeted drug therapy, clinical trials, or 10 supportive care.
  7. 7. Lung Cancer Discovered Scientists at MIT's Center for Cancer Research have discovered stem cells -- cells that do not yet have a specific function -- in the lung. Not only is this the first time anyone has found stem cells in the lung, but the team claims that these cells could be the precursor for lung cancer, the cancer that causes the greatest 11 number of deaths in the U.S. each year.
  8. 8. My Point of Interest I was mainly interested in learning about the treatments of lung cancer. I was not aware that different treatments were common for different stages of the lung cancer. For example, stage one was common for getting treated by surgery, however, stage 4 was mainly treated by chemotherapy. I learned that there are different factors of the lung cancer that determine the different treatments one receives, and this greatly interested me.
