5 warning symptoms of lung cancer to not be dismissed

Lung cancer is the leading cause of cancer-related deaths worldwide, according to the World Health Organization (WHO). In 85% of all cases, smoking is the leading cause. As this cancer has the highest mortality rates, catching the disease early is crucial. Most lung cancers are only diagnosed in the advanced stages, where the treatment options are limited. Being aware of the symptoms can help with early diagnosis. Here are some of the warning symptoms of lung cancer you should not ignore. A cough that does not go away One of the warning symptoms of lung cancer is a persistent cough. A cough that lingers for weeks or worsens over time is a red flag. It is different from the common cold or seasonal allergy. The cough may sound deeper, hoarser, or produce blood-tinged sputum. If the cough persists for more than three weeks, when paired with a history of smoking or exposure to secondhand smoke, it is important to consult a doctor.Chest painAnother hallmark symptom of lung cancer is chest pain. If you experience chest pain often, it is a cause for concern. How do you know if the chest pain is due to lung cancer? According to the American Cancer Society, chest pain that gets worse with deep breathing, coughing, or laughing is a symptom. Some may experience a dull pain or ache, for others it could be sharp. Though chest discomfort can happen from heart or muscle issues, it is important to investigate the unexplained pain.Shortness of breath or wheezing Lung cancer can contribute to breathing difficulties. If you struggle to breathe, wheeze, or feel unusually breathless during daily activities, it could be a sign of a tumour obstructing the airways. The shortness of breath may be subtle in the beginning, and could occur during daily activities, such as walking or climbing the stairs, and could gradually worsen. Many conditions, such as asthma or bronchitis, could also lead to breathing difficulties. Either way, this symptom should not be dismissed. Coughing up bloodIf you notice blood in phlegm or spit, it should never be overlooked. The blood in phlegm can appear as rust in colour, and even if the amount is small, you should consult a doctor. This condition is called hemoptysis, which signals bleeding within the lungs. This could happen due to the tumours irritating blood vessels. While many other conditions could also lead to coughing blood, it is a crucial symptom of lung cancer, and it requires immediate medical attention. FatiguePersistent fatigue is another warning sign. Feeling tired even after a good night’s sleep is a red flag. The lack of energy even to do normal activities can signal a serious underlying condition, including lung cancer. If this symptom is accompanied by other signs, it is vital that you consult a doctor right away. Disclaimer: This article is for informational purposes only and should not be taken as medical advice.
