It has been found that more men and women die of lung cancer each year than any other cancer. They are usually between the ages of 65 and 75. There are different types of lung cancer and the most common is the non-small cell lung cancer which roughly accounts for 80% of lung cancer. Each type grows at a different rate and responds differently to treatment. The symptoms that one experiences related to lung cancer vary depending on the type of lung cancer, how widespread it is and where the tumor is. There are many patients that experience a number of different symptoms or none at all.
Cancer related symptoms: Lung cancer grows in other parts of the body as well. The common lung cancer symptoms include coughing, chest pain, and shortness of breath, wheezing and coughing up blood. A person may experience difficulty swallowing due to an invasion of their Esophagus. Some faces a syndrome, called as ‘Pancoast’s Syndrome’. This involves cancer that has invaded nerves, causing shoulder pain that travels down the outside of person’s arm. Lung cancer can also grow into and block the veins that go from the upper part of the body to the heart. This causes the blood in the veins of face and upper chest to back up and veins get swollen. This syndrome is called as superior vena cava syndrome.
About one-fourth of total lung cancer patients do not experience any lung cancer symptoms. They may discover it through chest X-ray or CT scan. They do not report any symptoms at all when cancer is discovered.
How to Identifying Lung Cancer Symptoms
Lung cancer starts to begin when normal cells of the body undergo a permanent transformation when the cells become abnormal and begin to grow out of control. These changes can occur anywhere in the respiratory track and cause difficulty in breathing. The cells may grow in bronchus, alveoli or other surrounding areas. The most common symptom of lung cancer is a cough that does not go away. Other lung cancer symptoms include shortness of breath, wheezing, pain in the back, shoulders and chest. There are many factors that have long been associated with development of lung cancer among the people. Tobacco smoke is the leading cause of cancer and contributes to almost 90 percent of all cases. Other than cigarette smoking, reasons for lung cancer include environmental exposure to secondhand smoke, air pollution, and radon.
It has been reported that continuous exposure to industrial, cancer-causing agents like radiation, asbestos and arsenic also accounts for cause of lung cancer. The symptoms of lung cancer from which patients should be aware of and consult their doctor include coughing, unexplained weight loss, fatigue, wheezing, and many others. Lung cancer does not show any symptoms in the early stage and as the lung cancer advanced to a further stage, it starts showing more severe symptoms. Lung cancer is a horrible condition that deteriorates the functioning of lungs and it can also spread to other parts of body, if it is not discovered early. It is hard to detect lung cancer symptoms unless you experience certain re-occurring ones. Many patients discover their lung cancer when chest x-ray or CT scan is performed for some other disease.
When the lung cancer grows in the airway, it may also obstruct airflow. This can cause difficulties in breathing. In many cases, cancer has already spread beyond the original site by the time the symptoms are recognized. If you experience any of these symptoms, it is always advisable to consult your doctor and get proper tests performed. This article is written for informative purpose only.
Treatment of lung cancer:
The treatment process involves several forms of treatments such as chemotherapy, surgical removal of tumor, radiation therapy or a combination of these. The process of treatment depends on the location of the tumor, the extent of tumor and the overall health of patients. Treatment of lung cancer aims at either curing the cancer or reducing the person’s pain and sufferings. Surgery can only be done if the tumor is small and localized to one lung while the remaining lung is strong enough to work on its own.
