Transcript of Lung Cancer
There are two types of small cell lung cancer:
Small cell carcinoma (oat cell cancer)
Combined small cell carcinoma Description: Non-Small Cell is the most common type of lung cancer and grows much slower compare to small cell lung cancer.
There are 3 types of non-small cell lung cancer:
Adenocarcinomas are often found in the outer area of the lung.
Squamous cell carcinomas are usually found in the center of the lung next to an air tube (bronchus).
Large cell carcinomas occur in many different area of the lung. They grow and spread faster compare to the other two types of lung cancer. By Betty Wu Lung cancer is a type of cancer that starts from the "wind pipe" which is the bronchi. It's caused by the mutation of cells within the bronchi and they began to develop tumors. Then the tumors become malignant and turn into cancer and transfer to other body parts. Symptoms Diagnose Infection Treatment Prognosis Prevention Facts of Interest Reference: Early Stage Late Stage Early Stage: Chest pain
Cough that doesn't
Coughing up blood
loss of appetite
Wheezing Late Stage: Bone pain
Swallowing difficulty The End X-Ray CT Scan PET Scan Some Diagnose method include:
Chest CT Scan
MRI of the chest
Open lung biopsy Smoking Second hand smoking Minor Causes for Lung Cancer: Main Cause For Lung Cancer Research has shown that the number of cigarette you smoke every day and the amount of time you have smoked directly affect the risk of lung cancer. The more you smoke and the longer you smoke, the more likely you're going to get lung cancer. Second hand smoking increase the risk for lung cancer and according to American Cancer Society, an estimated of 3,000 adults die each year from second hand smoking caused lung cancer. Asbestos
Exposure to cancer-causing chemicals
Family history of lung cancer
High levels of air pollution
High levels of arsenic
Radon gas Treatments for lung cancer include: Surgery removal - surgically remove part of the lung that contains cancerous tumor
Chemo therapy- using drug to kill cancer cells and stop new cells from growing.
Radiation Therapy - using powerful x-rays or other forms of radiation to kill cancer cells
Laser therapy - a small beam of light burns and kills cancer cells
Photodynamic therapy - uses a light to activate a drug in the body, which kills cancer cell. However..... Lung cancer can only be cured during its early stages mostly by surgical removal when it hadn't transferred yet. At a late stage, treatment can only act as a pain killer but cannot cure the disease. If detect at a early stage, the treatment can only kill the cancerous cells temporarily and slow their expanding rate. Another important aspect to consider is the treatment that involves strong radiation can risk the danger of corrupting the body by killing too much normal functioning cells.

IV 2% Small cell lung cancer is rather deathly compare to non-small cell lung cancer for it spread and grow much quicker. Ways to prevent lung cancer: Lung Cancer Don't smoke or quit of you already started
Avoid second hand smoking
Watch out for obesity
Live in low pollution area
Long term use of vitamins
Avoid abusing alcohol
Moderate exercise Facts about lung cancer... Lung cancer kills more people each year than breast cancer, prostate cancer and colorectal cancer combined.
Non-smoking women are more likely to develop lung cancer than non-smoking men.
Smoker who quit at the age of 30 have double the risk of dying from lung cancer compare to non-smoker. Early Late Respiratory System: Lungs are the main organs of respiratory system. The purpose of this system is to supply oxygen and remove carbon dioxide from the body. Early stage of lung cancer blocks the airway and put part of the lung "out of function." Late stage lung cancer causes mucus affection and traps fluids that prevents oxygen from entering into the air sacs. Affect specialized cells: Lung cancer usually starts within the lining cells of the bronchi and causes them to be physically crowded.
Tumors can cause damage to the blood cells by blocking their passage in the lung.
After the cancer transferred to other parts of the body, all of the other cells will risk the potential of developing cancer. Facts about X-Ray X-ray produces a two dimensional image of the eternal organs in the body.
cheaper than similar medical procedures
easy to use
Don't give detailed image of the body
Causes radiation exposure and potential DNA damage Facts about CT Scan: Facts about CT Scan: CT Scan uses a combination of x ray and sophisticated computers to produce a highly accurate image of the body.
Takes less time to perform the test
Less restrictions for the patient
May cause cell damage due to the powerful x ray
Can damage fetus's growth Facts about PET Scan: PET Scan uses radiation to produce a three dimensional, colored image of the functional process of the body.
Can detect early symptoms for abnormal growth
Provide detailed image of the cells that are functioning in the body
Uses dangerous radiation for fetus or infant
Very new and expensive technique for diagnose Lung cancer may come back after the treatment. In some cases, the cancerous cells already spread to other parts of the body yet it's just too small to be detected. In other cases, cancerous cells escaped from the surgery and continue to grow. Daily life interruption: A research done by the U.S. Cancer Pain Relief showed that dyspnea and fatigue interfered with at least 1 daily activities. Pain interfered mostly with physical activities such as walking and working. Summary Lung cancer is a deathly disease with very little survival rate. It's especially dangerous for smokers or secondhand smokers. Due to the difficult early detection, patients often discover themselves in a late stage lung cancer. Although treatments can still be applied but they act nothing more than a painkiller. Lung cancer
rarely has any survivors and those people are
fortunate enough todetect cancer at a early stage.
