Lung cancer is a formidable adversary. It is the third most common type of cancer diagnosed in the country. However, its symptoms do not appear in the early stages. Rather, they can appear at advanced stages when treatment options become limited. Hence, recognizing the warning signs of lung cancer is crucial for early detection and improved prognosis. While symptoms can vary among individuals, here are common warning signs that should never be ignored.

Persistent cough
A persistent cough that lingers for over two to three weeks is one of the most common early warning signs of lung cancer. While coughing is a normal bodily function designed to clear the airways, a chronic and unrelenting cough can be indicative of an underlying health issue. Lung cancer often irritates the air passages, leading to a nagging cough that might produce blood-tinged mucus, also known as hemoptysis.

Shortness of breath
Another concerning symptom associated with lung cancer is shortness of breath or dyspnea. This symptom may manifest as increased difficulties in breathing, especially during physical activity or at rest. Further, lung tumors can obstruct the airways or invade lung tissue, reducing the lung’s capacity to function effectively.

Chest pain
Chest pain is a warning sign of lung cancer that often goes unnoticed or is attributed to less severe causes. Lung cancer-related chest pain can vary in intensity and location. It may be sharp, dull, persistent, or intermittent. Moreover, the pain can originate from the chest, back, or shoulder areas and result from tumor growth or nerve compression. Although not all chest pain is indicative of lung cancer, anyone experiencing persistent or unexplained chest discomfort should seek medical attention for a thorough evaluation.

Change in voice
A noticeable change in voice can also be a warning sign of lung cancer. While this symptom may not be as commonly associated with lung cancer as others, it can still provide important clues. For instance, the cancer may press against or invade the nerves that control the larynx (voice box), leading to hoarseness or a raspy voice. However, it’s important to note that voice changes can result from various causes, and ruling out potentially serious conditions like lung cancer is essential for early detection and treatment.

Fatigue and weakness
Although these are nonspecific symptoms associated with various medical conditions, they can also indicate lung cancer. But, in cancer patients, fatigue is often described as overwhelming and persistent, even after rest or sleep. This means it can interfere with daily activities and quality of life. While fatigue can have multiple causes, it should not be disregarded, especially when accompanied by other concerning lung cancer-related symptoms. Here, a healthcare provider can help determine the underlying cause of fatigue and recommend appropriate diagnostic tests.

In conclusion, early detection of lung cancer is vital for improving the chances of successful treatment and survival. While the above-mentioned five warning signs are common indicators of lung cancer, it’s essential to remember that not everyone with lung cancer will experience the same symptoms, and some individuals may have no symptoms at all in the early stages. So, if one is experiencing any of these symptoms or has other concerns about lung health, one must seek medical attention promptly.
