Unchecked cell division in the lungs is the condition that leads to lung cancer. Small cell and non-small cell lung cancer are the two primary types of the disease. The earliest symptoms of lung cancer can vary among individuals. Cancer staging is based on the size of initial tumor, how far or deep into the surrounding tissue it goes, and whether it’s spread to lymph nodes or other organs. Early detection can significantly improve treatment outcomes for lung cancer.
Which lung cancer symptoms appear first?
The earliest symptoms of lung cancer can vary among individuals and may not always be noticeable. In many cases, lung cancer may not show any symptoms until it has progressed to an advanced stage. However, some common early symptoms of lung cancer may include:
Persistent cough that doesn’t go away or worsens over time is a common symptom. It may produce bloody or rust-colored sputum. Constant chest pain that worsens with deep breathing, coughing, or laughing can be a symptom. Breathlessness or shortness of breath that persists even after rest or without exertion. A persistent hoarse voice or changes in voice quality. Significant and unexplained weight loss, despite a normal appetite, can be a symptom of various cancers, including lung cancer. fatigue or weakness that doesn’t go away with rest. Frequent respiratory infections such as bronchitis or pneumonia may be a sign of an underlying issue, including lung cancer.
It is noteworthy to mention that these symptoms can be caused by many other conditions as well, and having one or more of these symptoms doesn’t necessarily mean it is lung cancer.
However, early detection can significantly improve treatment outcomes for lung cancer.
Does lung cancer take time to develop?
According to cancer-related mortality rates for both sexes, lung cancer is the second most frequent type of cancer. It can progress at different rates. Early lung cancer does not alert obvious symptoms. Furthermore, lung cancer patients may go years without exhibiting any symptoms or indicators of the disease. Lung cancer staging is crucial step for prognosis or therapy recommendation.
Do these early symptoms help determine the stage of lung cancer?
Early lung cancer symptoms may provide hints, but they cannot determine the stage of the cancer. It takes several diagnostic tests and imaging examinations to evaluate the disease’s spread and pinpoint the exact stage. Lung cancer staging is important for healthcare professionals to identify.
The process of staging lung cancer includes determining the size of the tumour, the location of the lung cancer cells, and whether or not the cancer has spread. Lung cancer is generally staged as follows:
- Stage 0 (in-situ): The bronchus or upper lining of the lung has cancer. It hasn’t moved outside of the lung or to other areas of the lung.
- Stage I: Second-earliest stage of the disease. No distant portion of the body, including other organs, or lymph nodes have been invaded by cancerous cells. The main (original) tumour is at most 4 centimetres (cm) in size.
- Stage II: Cancer is larger than Stage I. There are many tumours in the same lung lobe, the cancer has migrated to internal lymph nodes.
- Stage III: Cancer is larger than Stage II, has expanded to adjacent organs or lymph nodes, or several tumours exist in separate lung lobes.
- Stage IV: Cancer has progressed to distant organs, the fluid surrounding the heart, the other lung, and the lung.
