All you need to know about Lung Adenocarcinoma

Lung Adenocarcinoma – An Overview

Lung adenocarcinoma mostly begins in tissues that are near the outer parts of the lungs. It may be present for a long time before causing noticeable symptoms and getting properly diagnosed. Adenocarcinoma is the most prevalent form of lung cancer found in women, and is more often found in non-smokers. It is also the most common type of lung cancer in people under the age of 45 and the most common type of lung cancer among Asians.

Overall, lung adenocarcinoma accounts for an increased number of lung cancer cases in recent years, whereas another form of non-small cell lung cancer, squamous cell carcinoma, has been decreasing.

Signs and Symptoms of Lung Adenocarcinoma

As lung adenocarcinoma often begin in the outer parts of the lungs, commonly seen symptoms of lung cancer such as a chronic cough and coughing up blood may be comparatively less common until later in the disease’s stage. Early symptoms of lung adenocarcinoma that may be ignored may include fatigue, mild shortness of breath, or achiness in your back, shoulder, or chest.

Diagnosing Lung Adenocarcinoma

The diagnosis of lung adenocarcinoma usually entails an initial x-ray imaging test to see for abnormalities in the lungs. The doctor may also chose to do advanced diagnostic tests such as a chest computerized tomography (CT) scan, a bronchoscopy, and positron emission tomography (PET) scan or sputum cytology for detailed diagnosis as well as staging the lung adenocarcinoma. The doctor might also perform a biopsy to collect a tissue sample of the abnormal mass in the lungs for detailed analysis in the laboratory.

Staging Lung Adenocarcinoma

The lung adenocarcinoma is categorized into four stages depending mainly on the area it has affected. The lung adenocarcinoma is divided into –Stage I – cancer that is restricted to the lungs only, Stage II – cancer that has spread to the lymph nodes or the lining of the lungs, Stage III – cancer has spread to the tissue around the lungs and Stage IV – cancer has spread to other parts of the body.

Causes of Lung Adenocarcinoma

The cause for Lung adenocarcinoma is mainly smoking tobacco. However, there are many cases where non-smokers have been affected by lung adenocarcinoma. The other common cause for development of lung adenocarcinoma is a person is exposure to radon at home. There are several other multiple factors that combine together to give rise to lung adenocarcinoma.

Lung Adenocarcinoma treatment procedures

The treatment for lung adenocarcinoma can be performed using various methods and techniques. The type of treatment will mainly depend on the stage of the cancer. The most common form of treatment for lung adenocarcinoma are:


The surgical treatment for lung adenocarcinoma is mostly affective and curative when the cancer is detected in its earlier stages. The doctor will consider several factors before advising surgical treatment for lung adenocarcinoma such as the type of lung cancer, the stage of the lung cancer, the location of the lung tumor as well as the general overall health of the patient.

The surgical treatment for lung adenocarcinoma can be performed using any one of the three methods:

  • Wedge resection (segmental resection) – This involves removing a portion of the lung affected by the cancer as well as some of the surrounding healthy tissue.
  • Lobectomy – This involves removing the affected lobe of the lung entirely to treat the present cancer as well as to avoid it from recurring in the healthy tissues later.
  • Pneumonectomy – This involves removing an entire lung, that is affected with the cancerous cells.


Chemotherapy uses medicinal drugs that are designed to destroy the cancerous cells in the body. It works by swiftly destroying the cancer cells and inhibiting their ability to divide. However, this treatment method is mostly performed in combination with surgery or radiation therapy for optimum results. It is useful in destroying widely-spread cancer cells, shrink a tumor for easier removal by other method, cure the cancer as well as to help relieve the symptoms seen in lung adenocarcinoma cases.

Targeted Therapy:

This cancer treatment technique requires using specialized medicinal drugs that are designed to specifically target the cancer cells only. This is comparatively more advanced and advantageous procedure than a traditional chemotherapy.

Radiation Therapy:

This cancer treatment technique involves using a beam of high-energy radiation to target the cancer cells and destroy them using the heat generated by the radiation beam. This is an effective treatment method for lung adenocarcinoma as well as being effective in controlling the symptoms that may result in the spread of the cancer to other parts of the body.
