Lung Cancer Research Paper

The body is composed of many types of cells. Mundanely, cells grow, divide and then die. Sometimes, cells mutate and commence to grow and divide more expeditiously than mundane cells. Rather than dying, these anomalous cells clump together to compose tumors. If these tumors are cancerous (withal called malignant tumors), they can invade and kill your body’s salubrious tissues. From these tumors, cancer cells can metastasize contrast, noncancerous tumors do not spread to other components of the body. One type of cancer, also the deadliest is Lung Cancer. Lung Cancer is the uncontrolled magnification of anomalous cells in one our both lungs. These aberrant cells do not carry out the functions of mundane lung cells and do not develop into salubrious lung tissues. As they grow, the anomalous cells can compose tumors and interfere with the functioning of the lungs, which provides oxygen to the body via blood. There are two main
types of cancer, small cell, and non-small-cell Lung cancer. The non-small cell grows slowly while in contrast the small cell Lung Cancer grows faster.

Lung Cancer is the most common type of cancer in the world, which also makes it the deadliest type of cancer in the world, taking more than 158,000 lives, and 200,000 new ones diagnosed every year. Lung Cancer is the cancer that starts in the lungs, the main cause of Lung cancer is because of cigarette smoking, the more and earlier you smoke, the higher your chances of getting cancer; Although smoking is one the main causes of cancer, nonsmokers can also be affected equally. Some causes of cancer, as stated by MedlinePlus are “exposure to asbestos, exposure to cancer-causing chemicals, exposure to radon gas, family history of cancer, high levels of pollution, and radiation therapy to the lungs” This means that even nonsmokers can still get Lung Cancer. Lung Cancer is usually found by an X-ray or a CT Scan, the procedure for cancer is as follows: The doctor will run a physical examination and ask about one's medical history, the doctor then will listen with a stethoscope and listen for fluids around the lungs. After the test has been concluded and a cancer is found then the doctor will assign treatments. Some treatments may include surgery to remove the tumor only if it has not spread far enough, Chemotherapy “spamming drugs to kill cancer cells and stop new ones from growing” (MedlinePlus) and Radiation therapy uses powerful rays to kill cancer cells.

The most common type of Lung Cancer is non-small cell lung cancer. It is also the slowest type of lung cancer. People who are most likely to get lung cancer are smokers or secondhand smokers, the three kinds of Non-Small Cell Lung cancer is Adenocarcinoma, Squamous cell carcinoma, and Large cell carcinoma. Adenocarcinoma usually starts in cells that make mucus or other substances, “often in outer parts of your lung” – WebMD. Squamous cell starts in inner airways of the lung, Large cell carcinoma grows and spreads the fastest, it is tougher to treat and accounts for 10-15% of lung cancer. NSCLC (Non-Small Cell Lung Cancer) is caused mostly because of smoking or people who is around smokers constantly, radon (a radioactive gas found naturally in soil and rocks as stated by Webmd), Asbestos, mineral and metal dust, air pollution, radiation treatment, and HIV or AIDS; It also may be passed down by the family. Symptoms of NSCLC may include coughing, chest pain, hoarseness of the voice, harsh raspy sound when breathing, wheezing, weight loss, coughing up blood or mucus, shortness of breath, feeling weak or tired, or long lasting lung problems such as bronchitis or pneumonia; if the cancer has spread to other parts of the body, symptoms such as bone pain, headache, dizziness, numbness, or yellow skin may occur. The treatment of NSCLC is like other type of cancers, Radiation kills cancer cell that remain after surgery; Chemotherapy is putting lots of different drugs into your body in hopes of killing cancer; Surgery is for earlier stage and is most recommend to get rid of the cancer, it removes the cancer but also may take organs with it such as the Lungs.

The other main type of Lung Cancer is small cell Lung Cancer.
Small cell lung cancer accounts for 10%-15% of all Lung cancer. Small cell is different than non-small cell because they grow more rapidly, spread quicker, and “responds well to chemotherapy” as stated by WebMD. Symptoms of Small-Cell Lung Cancer may include coughing (blood or other substances), shortness of breaths, chest pains; If the cancer spreads to other parts of the body, symptoms may be hoarse voice, shortness of breath, difficulty swallowing, or swelling of the face. Some tests and exams to determine if one has lung cancer may be a physical exam, CT scan of the chest (an X-ray machine), Thoracentesis (lung becomes enclosed in a sac), Bronchoscopy (a thin flexible lighted tube with a camera is inserted into the area of effect) a biopsy, or an Mediastinoscopy (tube inserted behind the breastbone through tiny cut at lowest part of the neck, samples are taken). Treatment of Lung cancer may include surgery, chemotherapy, radiation therapy, radiation and chemotherapy, or
surgery.

In conclusion Lung cancer is the most common and deadliest type of cancer in the world, it can be caused for many reasons; Some reasons may include smoking and secondhand smoking. The two types of cancer may include Non-small cell Lung cancer and Small cell lung cancer. Small cell lung cancer grows more fast and is less common, non-small cell lung cancer grows more slowly and is more common. They are treated both equally, most treatments may chemotherapy, radiation, and surgery; It may vary depending on the person and how they are diagnosed and when they are diagnosed.
