Lung Cancer Causes Symptoms Treatment is a complex and challenging disease that poses a significant health threat globally. It is the leading cause of cancer-related deaths, responsible for more deaths than breast, prostate, and colorectal cancers combined. This comprehensive article delves into various aspects of lung cancer, including its types, causes, risk factors, symptoms, diagnosis, treatment options, and emerging research.

Lung Cancer Causes Symptoms Treatment It is estimated that more than 14,700 people were diagnosed with lung cancer in 2023. The average age at diagnosis is 72 years old. Lung cancer is the fifth most commonly diagnosed cancer in Australia, and it is estimated that one in 20 people will be diagnosed by the time they are 85.

Lung Cancer Causes Symptoms Treatment starts when abnormal cells grow and multiply in an uncontrolled way. Cancer that begins in the lungs is called primary lung cancer. If cancer begins in another part of the body and spreads to the lungs it is know as secondary or metastatic cancer in the lung. Lung cancer is the leading cause of cancer death and the fifth most common cancer diagnosed in Australia excluding non-melanoma cancers. It is responsible for almost one in five cancer deaths in Australia.

  • Types of Lung Cancer: Lung Cancer Causes Symptoms Treatment is broadly classified into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC accounts for approximately 85% of all lung cancer cases, while SCLC is a more aggressive type, often associated with a higher rate of metastasis.
  • Types of NSCLC: Adenocarcinoma: Lung Cancer Causes Symptoms This is the most common type of NSCLC and often occurs in the outer parts of the lung. It is more common in non-smokers and women.
  • Squamous cell carcinoma: Lung Cancer Causes Symptoms This type typically develops in the bronchi lining and is often linked to smoking.
  • Large cell carcinoma: This is a less common type and can appear in any part of the lung. It tends to grow and spread quickly.
  • Causes and Risk Factors:
  • Smoking: Lung Cancer Causes Symptoms Treatment The primary cause of lung cancer is smoking, and the risk increases with the number of cigarettes smoked and the duration of smoking.
  • Exposure to secondhand smoke: Lung Cancer Causes Symptoms Non-smokers exposed to secondhand smoke are also at an increased risk.
  • Occupational exposure: Certain occupations, such as those involving exposure to asbestos, radon, or other carcinogens, may increase the risk.
  • Symptoms: Lung Cancer Causes Symptoms may include persistent cough, chest pain, shortness of breath, wheezing, fatigue, weight loss, and recurrent respiratory infections.
  • Diagnosis: Diagnosis often involves imaging studies like CT scans and PET scans, as well as tissue biopsy to confirm the type of lung cancer.
  • Staging: NSCLC is staged based on the size of the tumor, whether it has spread to nearby lymph nodes, and whether it has spread to other organs.
  • Treatment: Surgery: Lung Cancer Causes Symptoms Surgical removal of the tumor is an option if the cancer is confined to the lungs and has not spread extensively.
  • Targeted therapy and immunotherapy: These are newer approaches that target specific molecules involved in cancer growth or stimulate the immune system to fight cancer.
  • Radiation therapy: High-dose radiation is used to target and kill cancer cells.
  • Prognosis: Prognosis depends on the stage at which the cancer is diagnosed. Early-stage NSCLC has a better prognosis than advanced-stage disease.
  • Prevention: The most effective way to prevent NSCLC is to avoid smoking and exposure to secondhand smoke. Occupational exposure to carcinogens should also be minimized.

What is Lung Cancer

Lung Cancer Causes Symptoms
Lung Cancer Causes Symptoms

Lung Cancer Causes Symptoms Treatment Small cell lung cancer usually starts in cells that line the bronchi in the centre of the lungs. The main types of small cell lung cancer are small cell carcinoma and combined small cell carcinoma (mixed tumour with squamous or glandular cells).

Lung Cancer Causes Symptoms Treatment Non–small cell lung cancer usually starts in glandular cells on the outer part of the lung. This type of cancer is called adenocarcinoma. Non–small cell lung cancer can also start in flat, thin cells called squamous cells. These cells line the bronchi, which are the large airways that branch off from the windpipe (trachea) into the lungs. This type of cancer is called squamous cell carcinoma of the lung. Large cell carcinoma is another type of non–small cell lung cancer, but it is less common. There are also several rare types of non–small cell lung cancer. These include sarcoma and sarcomatoid carcinoma.

Lung Cancer Symptoms

Lung Cancer Causes Symptoms The symptoms of lung cancer can vary depending on the stage of the disease, the type of lung cancer, and other individual factors. Common symptoms include

  • Persistent Cough: A chronic cough that worsens over time is a common symptom of lung cancer. Coughing up blood may also occur.
  • Shortness of Breath: Lung Cancer Causes Symptoms Difficulty in breathing or shortness of breath may be a result of the tumor blocking or narrowing the airways.
  • Chest Pain: Pain in the chest, shoulders, or back can be a symptom of lung cancer. The pain may worsen during deep breathing or coughing.
  • Unintended Weight Loss: Lung Cancer Causes Symptoms Sudden and unexplained weight loss can be a sign of various cancers, including lung cancer.
  • Fatigue: General fatigue and weakness may occur due to the body’s response to the cancer or as a result of the cancer affecting the production of red blood cells.
  • Hoarseness: Lung Cancer Causes Symptoms Changes in the voice, such as hoarseness, may be a symptom if the cancer affects the nerves controlling the vocal cords.
  • Recurrent Respiratory Infections: Frequent infections like bronchitis or pneumonia may indicate an underlying issue with the lungs.
  • Persistent Cough: A chronic cough that worsens over time is a common symptom of lung cancer. Coughing up blood may also occur.
  • Shortness of Breath: Difficulty in breathing or shortness of breath may be a result of the tumor blocking or narrowing the airways.
  • Chest Pain: Pain in the chest, shoulders, or back can be a symptom of lung cancer. The pain may worsen during deep breathing or coughing.
  • Unintended Weight Loss: Sudden and unexplained weight loss can be a sign of various cancers, including lung cancer.
  • Fatigue: General fatigue and weakness may occur due to the body’s response to the cancer or as a result of the cancer affecting the production of red blood cells.
  • Hoarseness: Changes in the voice, such as hoarseness, may be a symptom if the cancer affects the nerves controlling the vocal cords.

Lung Cancer Diagnosis

The diagnosis of lung cancer typically involves a combination of medical history, physical examination, imaging tests, and laboratory tests. Common diagnostic procedures include

  • Imaging Tests: X-rays, computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET) scans can help identify the location, size, and extent of the tumor.
  • Biopsy: A biopsy involves taking a small sample of tissue from the tumor to examine it under a microscope. This is often the definitive method for confirming the presence of cancer and determining its type.
  • Sputum Cytology: Examining a sample of mucus coughed up from the lungs can help identify cancer cells.
  • Bronchoscopy: This procedure involves using a thin, flexible tube with a camera (bronchoscope) to examine the airways and collect tissue samples.
  • Thoracentesis: If there is fluid buildup around the lungs, a sample may be taken for analysis.

Lung Cancer Staging

Once lung cancer is diagnosed, staging is done to determine the extent of the disease and its spread. Staging helps guide treatment decisions and provides information about prognosis. Lung cancer is staged from I to IV, with higher stages indicating more advanced disease.

  • Stage I: Cancer is limited to the lung.
  • Stage II: Cancer may involve nearby lymph nodes.
  • Stage III: Cancer has spread to nearby structures or lymph nodes.
  • Stage IV: Cancer has spread to distant organs or tissues.

Lung Cancer Treatment

The treatment of lung cancer depends on several factors, including the type and stage of cancer, the patient’s overall health, and their preferences. Treatment options may include

  • Surgery: Surgical removal of the tumor is a common treatment for early-stage lung cancer. In some cases, a portion of the lung (lobectomy) or the entire lung (pneumonectomy) may be removed.
  • Radiation Therapy: High-dose radiation is used to kill cancer cells or shrink tumors. It can be used as a primary treatment or in combination with surgery or chemotherapy.
  • Chemotherapy: Drugs that kill cancer cells or inhibit their growth are administered through the bloodstream. Chemotherapy is often used in advanced stages or in combination with other treatments.
  • Targeted Therapy: Targeted drugs focus on specific molecules involved in cancer growth. They are designed to interfere with the cancer cells while minimizing damage to normal cells.
  • Immunotherapy: Immunotherapy boosts the body’s immune system to recognize and attack cancer cells. It has shown promising results in treating certain types of lung cancer.
  • Palliative Care: Palliative care focuses on improving the quality of life for individuals with serious illnesses, including lung cancer. It addresses symptoms and provides support for physical, emotional, and spiritual needs.

Lung Cancer Prognosis

The prognosis for lung cancer varies widely based on the stage at diagnosis, the type of cancer, and the overall health of the individual. Generally, lung cancer has a lower survival rate compared to some other cancers, primarily because it is often diagnosed at an advanced stage.

Early detection and advances in treatment options, however, have improved outcomes for some patients. Regular screenings for individuals at high risk, such as heavy smokers, can help detect lung cancer at an earlier, more treatable stage.

Lung Cancer Prevention

Lung Cancer Causes Symptoms Preventing lung cancer is closely linked to avoiding risk factors. Here are some preventive measures

  • Quit Smoking: The most effective way to prevent lung cancer is to quit smoking. It’s never too late to quit, and the risk decreases over time after quitting.
  • Avoid Secondhand Smoke: Limit exposure to secondhand smoke, as it can also increase the risk of lung cancer.
  • Test for Radon: Test homes for radon levels, and if elevated, take steps to reduce exposure.
  • Protect Against Workplace Hazards: If working in environments with known carcinogens, use protective measures to minimize exposure.
  • Healthy Lifestyle: Maintain a healthy lifestyle with a balanced diet, regular exercise, and limited alcohol consumption.
