Lung cancer is the number one cause of cancer-related deaths, according to The Merck Manuals, an online medical encyclopedia. This type of cancer occurs when cancerous cells form within the delicate tissues of the lungs. Patients who develop advanced lung cancer symptoms should seek additional medical care immediately to prevent further medical complications.
No Advanced Symptoms
Approximately 25 percent of patients with the advanced form of lung cancer do not experience noticeable symptoms, report health officials at the Centers for Disease Control and Prevention. This lack of symptoms can make it difficult for a doctor to identify and treat lung cancer in affected patients. Certain risk factors, such as smoking, asbestos exposure or family history, can increase a patient's likelihood of developing this disease, explains MayoClinic.com. Patients who have questions or concerns regarding lung cancer should seek further evaluation and care from a medical professional.
Cough
Cancer cells that grow and replicate within the lung tissue can inflame and irritate this vital organ. As a result, patients can develop a persistent or chronic cough as an advanced lung cancer symptom, explains UpToDate, a peer-reviewed medical information website for patients. Cough symptoms are typically dry and hacking and do not resolve on their own. Patients who develop persistent or severe cough symptoms should speak with a doctor as soon as possible.
Bloody Mucus
Lung inflammation can cause patients to spit up small amounts of blood as an advanced symptom of lung cancer. Patients can expel blood-tinged mucus or sputum during episodes of persistent coughing. Affected patients should report these symptoms to a health care professional as soon as possible.
Breathing Difficulties
Excess cell growth within the lungs can make it difficult for air to normally pass through a patient's airway. Additionally, inflammation caused by cancer cell growth can narrow and tighten the airway passages. When this occurs, patients with advanced lung cancer can develop breathing difficulties, such as wheezing or shortness of breath, explain CDC health officials. Patients with sudden or severe breathing difficulties require medical attention as soon as possible to prevent additional complications.
Chest Pain
Chest pain or discomfort can occur as symptoms of advanced lung cancer in affected patients, according to MayoClinic.com. These symptoms typically accompany chronic coughing episodes in patients with lung cancer. Patients who develop sudden or severe chest pain should seek immediate medical care as this symptom can also be a sign of other health conditions, such as a heart attack.
Flulike Symptoms
Patients with advanced lung cancer can develop flu-like symptoms due to this disease. Flu-like symptoms can include fatigue, weakness, headache, bone pain, decreased appetite or weight loss, explains MayoClinic.com. Patients who develop these symptoms should consult a physician as flu-like symptoms can be signs of other medical conditions.
