World Lung Cancer Day, observed annually on August 1st, raises awareness about the prevalence, risks, and prevention of lung cancer, a disease that claims millions of lives worldwide. While well-known symptoms like persistent cough and shortness of breath are commonly associated with lung cancer, there are lesser-known signs that should not be overlooked. Early detection is crucial in improving outcomes and survival rates, making it essential to recognize these subtle indicators.
1. Persistent Chest or Back Pain
While chest pain can be a symptom of various conditions, persistent or worsening pain, especially if it radiates to the back or shoulder, could be a warning sign of lung cancer. This pain may not necessarily be related to coughing or breathing and can be mistaken for musculoskeletal issues.
2. Unexplained Weight Loss
Unintentional weight loss, without any apparent reason such as changes in diet or exercise, can be a symptom of various cancers, including lung cancer. This can occur due to the body's increased metabolic rate as it fights the disease or due to loss of appetite associated with cancer.
3. Hoarseness or Voice Changes
Changes in the voice, such as hoarseness or a raspy sound, can be an early sign of lung cancer. This occurs when a tumour presses on the nerves that control the vocal cords. Persistent voice changes, especially if they last for more than two weeks, should be evaluated by a healthcare professional.
4. Chronic Fatigue
Fatigue that is not relieved by rest and significantly affects daily activities can be an indicator of lung cancer. This fatigue is different from normal tiredness and can be a result of the cancer itself or due to anemia, which is common in cancer patients.
5. Frequent Infections
Lung cancer can lead to frequent respiratory infections such as bronchitis or pneumonia. If you find yourself repeatedly falling ill with these infections, it may be worth discussing with your doctor, especially if you have a history of smoking or other risk factors for lung cancer.
6. Swelling in the Face and Neck
Lung cancer, particularly small cell lung cancer, can cause swelling in the face, neck, arms, and upper chest. This occurs due to a condition known as superior vena cava syndrome, where a tumour blocks the superior vena cava, a large vein that carries blood from the upper body to the heart.
7. Clubbing of Fingers
Clubbing refers to the thickening of the fingertips, with nails curving around the fingertips. This can be a result of conditions like chronic lung disease, including lung cancer. It's a sign that requires medical evaluation.
8. Bone Pain
Lung cancer can spread to other parts of the body, including the bones. This metastasis can cause bone pain, which is often worse at night or with movement. Pain can be felt in the back, hips, or other bones.
9. Nerve Problems
Lung cancer can cause neurological symptoms if it spreads to the brain or if a tumour presses on a nerve. Symptoms can include headaches, dizziness, balance issues, or weakness in the limbs.
Awareness and Early Detection
It's important to note that these symptoms can be caused by conditions other than lung cancer. However, if you or someone you know is experiencing any of these symptoms, particularly if they persist or worsen, it's crucial to seek medical advice. Early detection of lung cancer can significantly improve the chances of successful treatment.
On this World Lung Cancer Day, let's spread awareness about these lesser-known symptoms and encourage regular check-ups, especially for those at higher risk. By being vigilant and informed, we can contribute to early detection and better outcomes for those affected by this disease.
