What are the symptoms of lung cancer?

Introduction

Lung cancer is a leading cause of cancer-related deaths worldwide. Understanding the symptoms associated with lung cancer is crucial for early diagnosis and effective management. This synthesis presents key insights from multiple research papers on the symptoms of lung cancer.

Key Insights

Common Symptoms:
- Pain, dyspnea (difficulty breathing), and anorexia are among the most common and severe symptoms experienced by lung cancer patients.
- Fatigue, cough, and dyspnea form a persistent symptom cluster that can last up to five years after diagnosis.
- Haemoptysis (coughing up blood) is a significant initial symptom associated with lung cancer, although it occurs in only about 21.6% of cases.
Symptom Clusters:
- A cluster of symptoms including fatigue, weakness, weight loss, appetite loss, nausea, vomiting, and altered taste is present at the time of lung cancer diagnosis and remains consistent over time.
- The symptom cluster of fatigue, cough, and dyspnea is stable among lung cancer survivors, particularly in the first two years after diagnosis.
Symptom Predictors and Variability:
- The stage of cancer at diagnosis is the most predictive factor for the number and severity of symptoms reported later in the disease.
- Males aged 64 and under report higher incidences of easy fatigue, taste changes, and sleep problems, while men over 64 report higher incidences of cough and significant weight loss.
Impact of Symptoms on Diagnosis and Prognosis:
- Chest/shoulder pain is associated with a shorter diagnostic interval for cancer compared to non-cancer diagnoses.
- The presence and severity of symptom clusters can predict the likelihood of death within 6 to 19 months after diagnosis.

Conclusion

Lung cancer is characterized by a range of symptoms, with pain, dyspnea, and anorexia being the most common. Symptom clusters such as fatigue, cough, and dyspnea persist over time and can significantly impact prognosis. Early identification of symptoms like haemoptysis and chest pain can aid in quicker diagnosis. The stage of cancer at diagnosis remains a critical predictor of symptom severity and patient outcomes. Understanding these symptom patterns is essential for improving patient care and management strategies.

Symptoms of lung cancer

Lung cancer patients experience a wide range of symptoms, with pain, dyspnea, and anorexia being the most common and severe, and palliative care being crucial due to limited effective treatments.

Fatigue, dyspnea, and cough comprise a persistent symptom cluster up to five years after diagnosis with lung cancer.

A single symptom cluster of fatigue, dyspnea, and cough persists in lung cancer survivors up to five years after diagnosis, initially increasing the risk of death but becoming more stable after Year 2.

Symptoms and other factors associated with time to diagnosis and stage of lung cancer: a prospective cohort study

Haemoptysis is the strongest symptom predictor of lung cancer, but occurs in only a fifth of patients.

A Cluster of Symptoms Over Time in Patients With Lung Cancer

The symptom cluster of fatigue, weakness, weight loss, appetite loss, nausea, vomiting, and altered taste remains over time in lung cancer patients, and is an independent predictor of death.

[Constrictive pericarditis as the first sign of lung cancer].

Constrictive pericarditis can be the first sign of lung cancer, leading to dyspnea, chest pain, and lower limb edema, and often fatal death within a few days.

Lung cancer

Lung cancer is most often caused by long-term tobacco smoking, but it can occur in people who have never smoked.
