LUNG CANCER SYMPTOMS IN WOMEN
Symptoms of lung cancer in women can differ from symptoms of lung cancer in men. One of the reasons that symptoms can lung cancer symptoms in women differ between the sexes is that most common types of lung cancer vary between sexes and also different types of lung cancer tend to have different symptoms. Swelling is one of commonest and the important sign in clinical diagnosis and it is associated with pain. Indeed, “Pain” is the most common symptom causing patients to seek attention.
What is a Cancer? Cancer is a cell that has lost its normal control mechanism and thus has unregulated growth. The first lung cancer symptoms and signs step in the process is initiation, in which a change in the cell’s genetic material triggers the cell to become cancerous. The lungs, the largest of the respiratory system, look like a large pink sponges that almost fill the chest. The left lung is a little smaller than the right lung because it shares space with the heart in the left side of the chest. Each lung is divided into sections (lobes): three in the right lung and two in the left. The primary functions of the respiratory system are to bring oxygen into the lungs, transfer oxygen to the blood and expel the waste products called carbon dioxide. The inhaled oxygen enters the lungs and reaches the alveoli. Of all people with lung cancer may have no symptoms when the cancer is diagnosed. The cancers are usually identified incidentally when an X-ray is performed on routine examination or another reason. Most lung cancers originate in the cells of the lungs; however cancer may also spread (metastasis) to the lung from other par of the body. Lung cancer is the most common in both men and women.
One of the reasons that symptoms can differ between the sexes is that most common types of lung cancer vary symptoms lung cancer between sexes and that different types of lung cancer tend to have different symptoms. Another cogent reason is that more non-smoking women than men develop lung cancer. What’s more? The most common types of lung cancer found in non-smokers are also often different than the most common types found in people who smoke. There are three types of non-small cell lung cancers namely, Adenoma-carcinoma, Squamous Cell Carcinoma and Large Cell Carcinoma. The most common type of lung cancer in women is adenocarcionoma which tend to grow in the outer regions of the lungs and the tumors grow quite large and spread before they can cause any symptoms. The initial symptoms in women include shortness of breath, back, shoulder pain, and fatigue. The symptoms of lung cancer depend of its type, its location and the way it spreads. Usually the main symptoms are a persistent cough. People with chronic cough who develop lung cancer often notice that their coughing becomes worse. Their sputum may be streaked with blood. If the cancer grows into the underlying blood vessels it may cause severe bleeding. Symptoms of primary lung cancers include cough, coughing up blood, chest pain and shortness of breath. A cough in a smoker or a former smoker should raise concern for lung cancer. Also, a persisting cough that does not go away or gets worse over time should be evaluated by a health-care-provider. Importantly, coughing up blood occurs in a significant number of people who have lung cancer. Thus, any amount of coughed-up-blood is a cause for concern. Chest pain is symptom in about one-fourth of people with lung canacer.The pain is dull, aching and persistent. Shortness of breath usually results from a blockage to the flow of air in part of the lung, collected around the lung, or the spread of tumor through out the lungs. More than 90% of lung cancers start in the bronchi, the large airways that supply the lungs. This type of cancer is called bronchogenic carcinoma. There are also squamous cell carcinomas typically originated in the lungs large breathing tubes (bronchi); small cell carcinoma, or oat cell cancer because of its oat-grain-like shape when viewed under the microscope. This is the presentation of lung cancer symptoms in women.
