Understanding the Condition
The lungs are essential organs responsible for bringing oxygen into the body and removing carbon dioxide from the bloodstream. Because the lungs are constantly exposed to the environment, they can develop a variety of abnormalities, including benign nodules and malignant tumor.
At Nordic Focal Therapies, we specialise in the image-guided diagnosis and management of selected lung tumor and pulmonary lesions. Using advanced CT imaging and minimally invasive techniques, our specialists help patients receive accurate diagnoses and explore personalised treatment options.
Modern imaging has significantly improved the detection of lung abnormalities. Many lung nodules are now discovered at an early stage, allowing specialists to carefully evaluate their nature and determine the most appropriate approach.
What Are Lung Tumor?
A lung tumour is an abnormal growth of cells within the lung tissue. Lung tumor can be either benign or malignant.
Some lung abnormalities are small and harmless, while others may represent early-stage lung cancer or metastatic disease that has spread from another part of the body.
A key challenge in lung medicine is determining whether a detected nodule is:
Benign and suitable for monitoring
Suspicious and requiring further investigation
Malignant and requiring treatment
Accurate imaging and, when necessary, tissue diagnosis play an essential role in making this distinction.
Types of Lung Tumor and Pulmonary Lesions
Primary Lung Cancer
Primary lung cancer begins in the cells of the lung itself.
The two main categories are:
Non-small cell lung cancer (NSCLC)
This is the most common type of lung cancer and includes:
Adenocarcinoma
Squamous cell carcinoma
Large cell carcinoma
Small cell lung cancer (SCLC)
This is a less common but faster-growing form of lung cancer.
Treatment decisions depend on many factors, including tumour type, stage, location, overall health, and other medical conditions.
For selected patients with limited lung tumor, minimally invasive image-guided treatments may be considered as part of a multidisciplinary treatment plan.
Pulmonary Nodules
A pulmonary nodule is a small abnormal area in the lung that appears as a rounded spot on imaging.
Pulmonary nodules are common findings, especially with the increasing use of CT scans.
Many nodules are benign and may be related to:
Previous infections
Inflammation
Scar tissue
Non-cancerous growths
However, some nodules require closer evaluation to determine whether they represent early lung cancer.
Assessment depends on factors such as:
Size
Shape
Growth over time
Appearance on CT imaging
Patient risk factors
Lung Metastases
Lung metastases occur when cancer from another part of the body spreads to the lungs.
Common primary cancers that may spread to the lungs include:
Colorectal cancer
Kidney cancer
Breast cancer
Melanoma
Sarcomas
Other solid tumor
The management of lung metastases depends on the original cancer type, number and location of lesions, and the overall treatment strategy.
Symptoms of Lung Tumor
Many lung tumor do not cause symptoms in their early stages. Some are discovered incidentally during CT examinations performed for other reasons.
When symptoms occur, they may include:
Persistent cough
Coughing up blood
Shortness of breath
Chest discomfort or pain
Unexplained weight loss
Fatigue
Recurrent respiratory infections
Changes in a long-standing cough
These symptoms can have many causes, which is why accurate imaging and specialist assessment are important.
How Lung Tumor Are Diagnosed
The diagnosis of lung tumor is based on a combination of imaging findings, clinical information, and sometimes tissue analysis.
CT Imaging
Computed tomography (CT) is one of the most important tools for evaluating lung abnormalities.
CT imaging provides detailed information about:
The size and location of lung nodules
The shape and characteristics of lesions
Changes over time
Relationship to nearby structures
CT also plays an important role in planning image-guided procedures.
PET-CT
In selected patients, PET-CT may provide additional information about the activity of a lung lesion.
It can help specialists evaluate:
Metabolic activity of suspicious lesions
Possible spread of disease
Overall cancer staging
Ultrasound and Other Imaging
Depending on the location of the lesion and the clinical situation, additional imaging methods may support diagnosis and treatment planning.
Image-Guided Lung Biopsy
When imaging cannot determine the nature of a lung lesion, a biopsy may be recommended.
During an image-guided lung biopsy, specialists use CT guidance to precisely position a thin needle into the lung lesion and obtain a small tissue sample.
The sample can then be analysed to determine:
Whether the lesion is cancerous
The exact tumour type
Molecular characteristics that may influence treatment decisions
Image-guided biopsy provides important diagnostic information while using a minimally invasive approach.
How Lung Tumor Are Evaluated
Every lung lesion requires an individual assessment.
Specialists consider factors including:
Size and appearance of the lesion
Location within the lung
Growth pattern on previous imaging
Type of tumour suspected
Presence of other disease
Overall health
Previous cancer treatments
Patient preferences and goals
The aim is to determine whether monitoring, further investigation, or treatment is the most appropriate approach.
The Role of Image-Guided Medicine
Advances in interventional radiology have created new possibilities for selected patients with lung tumor.
Image-guided techniques allow specialists to:
Accurately target lung lesions
Obtain tissue samples with precision
Plan minimally invasive treatments
Reduce unnecessary impact on surrounding healthy lung tissue
For carefully selected patients, local image-guided therapies may provide an alternative treatment approach when surgery is not suitable or when targeted local control is needed.
When Should You Seek Specialist Assessment?
A specialist review may be appropriate if you:
Have been diagnosed with a lung tumour
Have a suspicious pulmonary nodule on CT imaging
Need a tissue diagnosis
Have lung metastases from another cancer
Want an expert review of your imaging findings
Are exploring minimally invasive treatment options
Early assessment can help clarify the diagnosis and guide the next steps in care.

Frequently Asked Questions
Are all lung nodules cancerous?
No. Many pulmonary nodules are benign and do not represent cancer. Their significance depends on factors such as size, appearance, growth, and individual risk factors.
How are lung tumor detected?
Many lung tumor and nodules are discovered during CT imaging performed for symptoms, screening, or unrelated medical reasons.
Is a lung biopsy painful?
CT-guided lung biopsy is performed using local anaesthesia. Most patients experience limited discomfort, although temporary symptoms such as mild chest discomfort can occur.
Can lung tumor be treated without surgery?
For selected patients, minimally invasive image-guided treatments may provide an alternative or complementary option to surgery. Suitability depends on tumour characteristics and overall health.
What happens after a lung nodule is found?
The next step depends on the appearance and size of the nodule. Some require follow-up imaging, while others may need biopsy or treatment.
Will I need follow-up imaging?
Yes. Follow-up CT imaging is often an important part of monitoring lung nodules and evaluating treatment response.
