Lung Cancer
By:Brianna Rogers
One of the most prominent causes of death in today’s society is cancer. Focusing on one individually, Lung cancer. The most common cause of cancer-related death in men and the second most common in women. It is responsible for 1.3 million deaths worldwide annually. Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis, attack the nearby tissue and access beyond the lungs. The majority of main lung cancers are carcinomas of the lung, resulting from epithelial cells.
The leading cause of lung cancer is the use of Cigarettes (tobacco) contains carcinogens, which irritate and damage the cells in the lungs and airways. Over
time, these damaged cells may become cancerous. The likelihood that a smoker will develop lung cancer is affected by the age at which smoking began, how long the person has smoked, the number of cigarettes smoked per day, and how deeply the smoker inhales. Cigarettes are not the only cause of lung cancer, the quantity of lung cancer in non-smokers, who account for fewer than 10% of cases, appears to be due to a combination of genetic factors, radon gas, asbestos, and air pollution, including second-hand smoke.
Common symptoms of Lung cancer are; Coughing, shortness of breath, wheezing, chest pain, Hemoptysis (coughing up blood), loss of appetite, weight loss, and Pneumonia. These are universal symptoms of lung cancer. There are many minor symptoms including weakness, chills, difficulty swallowing, speech difficulties, and skin paleness or blush discoloration. Easy ways to identify lung cancer is chest x-ray and computed tomography (CT scan). The diagnosis is confirmed with a biopsy. This is usually performed via bronchoscopy or CT-guided biopsy. Treatment and prognosis depend upon the histological type of cancer, the stage (degree of spread), and the patient’s performance status.
Treatments can vary with the how malignant the cancer is, what stage it is at, and how much damage it has already caused. The main types of lung cancer are small cell lung carcinoma and non-small cell lung carcinoma. This distinction is important because the treatment varies; non-small cell lung carcinoma (NSCLC) is sometimes treated with surgery, while small cell lung carcinoma (SCLC) usually works better to chemotherapy
There are 4 stages to Lung cancer.
Stage 0: Cancer is almost unidentifiable and very rare that you will show symptoms, curable with surgery to remove a small part of the lung in an operation called a segmentectomy or wedge resection.
Stage1: Cancer is also uncommon. The most likely operation is a lobectomy.
Stage2: Cancer symptoms start, to cure it a lobectomy, like stage,. If the cancer is completely removed, your specialist may suggest chemotherapy to try to lower the risk of the cancer coming back. If you are unable to have surgery, you may be offered radiotherapy as a curative treatment
Stage3: Very visible from x-ray, and symptoms persist. You may need to have the whole lung removed, if you have cancer spread to the middle of the chest.
Stage4: At this point the non-small cell cancer is going to be impossible to cure, but using chemotherapy helps slow the spread and relive pain.
