Lung cancer ranks among the top cancer-causing deaths worldwide and is usually discovered only at an advanced stage. Detection at an early stage will improve survival rates, but such signs are often overlooked. Many of these symptoms should be recognized, and people should seek immediate medical evaluation, including a CT scan where possible, to make a big difference in outcomes.
Is a Persistent Cough a Painless Sign of Lung Cancer?
A persistent cough that haunts you for more than eight weeks is indeed an early indicator of lung cancer. Occasional coughing is not unusual, but a persistent cough that gets worse over time coughs up blood, or turns phlegm-colored should not be ignored. In this study by Rivera et al. (2020), one of the most common symptoms reported by lung cancer patients is persistent coughing, thought to be an external infection or allergies that last. If a cough doesn’t respond to usual treatments, it is a good idea to have a CT scan or, more specifically, a lung scan to find out what is causing it.
Why Does Shortness of Breath Occur in Lung Cancer Patients?
Dyspnea occurs when lung tumors block airways or fill fluid in the lungs. Gradually, this symptom may develop, and it may become apparent during physical activity. However, as it progresses, even basic tasks such as climbing the stairs or taking short walks can be very difficult. According to Wang et al. (2021), shortness of breath is commonly linked to reduced lung function resulting from the growth of tumors and, thus, a symptom for early detection. Seeking medical attention and having a lung scan to diagnose lung conditions can help if breathing difficulties persist.
Is Unexplained Weight Loss Related to Lung Cancer?
Unexplained weight loss is a common symptom of several cancers, including lung cancer. The spread of such cells to other parts of the body, when they create a different metabolism in the body, can cause rapid weight loss with no diet change. In addition to unintended weight loss, patients may have poor appetite or are extremely fatigued. Rivera et al. (2020) note that more than 60% of lung cancer patients at the time of diagnosis suffer considerable weight loss. A CT scan ought to be done if anyone has unexplained significant weight loss (more than 10 percent of body weight) within 6 months.
What Role Does Chest Pain Play in Lung Cancer Diagnosis?
Other alarming symptoms include chest pain. Tumor growth in lung cancer patients can cause chest pain if it presses on the chest wall, nerves, or ribs. It can be a persistent pain, or it can be intermittent and gets more painful with deep breathing, coughing, or laughing. Wang et al. (2021) suggest that chest pain stemming from the removal of lung tumors near the pleura (the membrane that surrounds the lungs) is more common. A person’s doctor can seek a CT scan to rule out any problems if they have unexplained chest discomfort, together with other symptoms such as coughing or breathlessness.
