Lung cancer is one of the most dangerous types of cancer. This disease not only affects the respiratory system but can also lead to various serious complications that impact the patient's quality of life. Understanding these potential complications is crucial for early detection and appropriate treatment.
Respiratory Complications
Shortness of breath, also known as dyspnea, is one of the most common symptoms experienced by lung cancer patients. It can occur when cancer cells block the airways in the lungs. Around 15% of lung cancer patients also suffer from pleural effusion, which is the buildup of fluid between the chest wall and the lungs. This fluid makes it difficult for the lungs to expand properly, resulting in labored breathing.
Coughing up blood is another complication to watch for, as it may occur when there is bleeding in the airways. Additionally, about 20–40% of lung cancer patients experience chest pain, which happens when a tumor presses on nerves or tissues, causing tension in the chest.
Long-Term Effects of Treatment
After treatment, some patients may experience long-lasting side effects. Cancer-related fatigue is the most common long-term side effect. Unlike normal tiredness, this fatigue does not improve even with adequate rest.
Moreover, certain treatments—such as chemotherapy, targeted therapy, immunotherapy, and radiation to the chest area—can cause heart damage (cardiotoxicity). These effects may only become apparent years after treatment has ended.
Paraneoplastic Syndrome
Around 10% of lung cancer cases can lead to paraneoplastic syndrome, a condition where the tumor produces hormones or other signaling molecules that affect parts of the body outside the lungs. Symptoms can vary widely, including nerve or muscle disorders and hormonal imbalances. Sometimes, these symptoms appear before the cancer itself is detected. In about 60% of lung cancer cases, this syndrome can serve as an early warning sign before a formal diagnosis is made.
Early Detection: The Key to Reducing Complications
Detecting complications early is crucial to enable faster and more targeted treatment. With advanced technology and support from experienced medical professionals, KALGen Innolab offers comprehensive lung cancer screening services. Regular check-ups can help prevent further complications and increase the chances of successful treatment.
