Lung malignancies

What are lung malignancies?
Lung malignancies, commonly referred to as lung cancer, initiate in the lungs themselves. This form of cancer is categorised into two primary types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

While smoking remains a significant causative factor, lung cancer can also manifest in individuals who do not smoke, attributed to environmental exposures like second-hand smoke, radon, asbestos, or air pollution.

 

WHAT ARE THE SIGNS?

Signs and symptoms of lung malignancies may vary depending on the type and stage of cancer, but common signs may include:

  • Persistent cough
  • Chest pain
  • Shortness of breath
  • Wheezing
  • Coughing up blood
  • Fatigue
  • Unintentional weight loss
  • Hoarseness

HOW ARE LUNG MALIGNANCIES DIAGNOSED?

Diagnosing lung malignancies typically involves utilising a combination of imaging modalities, such as chest X-rays, CT scans, and PET scans, alongside biopsy techniques to collect tissue samples for microscopic scrutiny. Common diagnostic approaches include:

  • Bronchoscopy: This procedure entails the insertion of a thin, flexible tube that has a camera through the nose or mouth to the lungs to examine the airways and collect tissue samples.
  • Needle biopsy: Utilising a needle, a small segment of lung tissue is extracted either through the chest wall or with imaging guidance for subsequent analysis.
  • Thoracentesis: This procedure involves the insertion of a needle into the pleural space that is located between the lungs and chest wall to extract excess fluid for examination.

After confirming the diagnosis, additional tests may be conducted to determine the stage and extent of the cancer.

HOW DO YOU TREAT LUNG MALIGNANCIES?

The approach to treating lung malignancies varies based on numerous factors, such as the cancer type and stage, alongside the patient's overall health and personal preferences. Treatment possibilities encompass:

  • Surgery: In cases of early-stage lung cancer, surgical excision of the tumour and adjacent tissue may be viable.
  • Radiation Therapy: High-energy radiation is employed to eradicate cancer cells or reduce tumour size.
  • Chemotherapy: Potent medications are utilised to destroy cancer cells or impede their proliferation.
  • Targeted therapy: Drugs that target specific abnormalities in cancer cells are used to block their growth and spread.
  • Immunotherapy: Drugs that help the body's immune system recognise and attack cancer cells are used to treat some types of lung cancer.

FAQ

1Can lung malignancies be prevented?
While some risk factors for lung malignancies, such as smoking and environmental exposure to carcinogens, can be mitigated by lifestyle changes and avoidance of toxins, not all cases of lung cancer are preventable. However, early detection through screening programs for high-risk individuals can improve outcomes by enabling timely intervention.
2What is the prognosis for lung malignancies?
The prognosis for lung malignancies depends on various factors, including the type and stage of cancer, the effectiveness of treatment, and the patient's overall health. Early detection and treatment can significantly improve prognosis, while advanced-stage cancers may have a poorer outlook. Regular follow-up care and adherence to treatment plans are essential for managing lung malignancies effectively.
3What are the risk factors for developing lung malignancies?
Smoking, whether actively or through exposure to second-hand smoke, stands out as the leading risk factor for lung cancer. Additionally, other contributing factors comprise exposure to environmental pollutants like radon, asbestos, and air pollution, a family history of lung cancer, and specific genetic predispositions.
