Early Symptoms of Lung Cancer
As with most cancers, the earlier you detect lung cancer the better your chances of survival. In fact, when it’s caught in the first stages, there’s an almost 50% survival rate after five years. This is a remarkable number considering the fact that overall, lung cancer has only a 15% survival rate.
Lung cancers are mainly of two types: small-cell-lung-cancer – also known as oat cell cancer, since it resembles oat grains and non-small-cell-lung-cancer. The aggressiveness of the disease and treatment option, depend on the type of cancer diagnosed. Many types of lung cancer grow & spread very quickly and since the lungs are vital organs, hence it is critically important to detect & treat the same – usually by surgery for removal of tumor.
In medical terminology, the malevolent transformation and expansion of lung tissues causes cancer in lungs, in simple words, the rapid growth of abnormal cells in the lungs leads to cancer which may start anywhere in the lungs and cause respiratory issues, healthy tissues are destroyed and invaded and the whole body is affected.
The moment cancer cells becomes malignant, it is termed as lung cancer in the primary stage. If a person gets lung cancer and he or she is not a smoker nor is exposed long-term to chemicals and lung irritants, it is deemed that the cancer may have come some place else from the body.
Lung cancer is caused by the presence of cancer cells. These abnormal cells continue to divide on their own without following a particular order or pattern. Because of this nature in the cells, they have the potential to destroy the neighboring tissues of the body.
Tumour stimulates the trachea, will often lead to irritating cough. This cough has nothing to do with the season, time or medication. This is the most common symptoms of lung cancer, and about 2/3 of the patients have this symptom. People must be prudent when there is a cough of unknown causes.
During the exam your doctor may use a thin tube called an endoscope to look radiant tumor in the internal body cavity. Endoscopic procedures are used depending on the organ or body cavity inspection. In gastric endoscopy, the doctor feeds a specialized endoscope into the throat to examine the layers of the esophagus, stomach and first part of the small intestine.
When cancerous cells spread throughout the lung tissue and threaten to metastasize to other organs, a new host of symptoms may manifest. Common sites of lung cancer metastasis include the brain, liver, and bones. If the disease spreads to your brain, you may experience vision problems, seizures, and persistent headaches.
What if you don’t smoke and you have a persistent cough for more than 3 weeks. You may have been around people who smoke constantly or exposed to an area where there was constant smoke.
Another symptom of lung cancer is blood or brown tinged colored sputum. Sputum is mucus that you cough up when you have a cold. If you do not have a cold and you cough this up in the morning or during the day pay attention to the color.
