Mucinous adenocarcinoma is a type of lung cancer and one of the main subtypes of non-small cell lung cancer. This tumour gets its name because the cancer cells produce large amounts of a sticky fluid called mucin. Mucinous adenocarcinoma typically develops in the outer parts of the lungs, and it can sometimes affect multiple areas …

Pneumocytes are specialized cells found in the lungs. They line tiny air sacs called alveoli. Alveoli are important because they help transfer oxygen from the air you breathe into your blood. They also help remove carbon dioxide from your blood so you can breathe it out. Types of pneumocytes There are two types of pneumocytes, …

SMARCA4-deficient undifferentiated tumour of the lung is a rare and aggressive type of lung cancer. The term “undifferentiated” means that the cancer cells do not look like normal lung cells. The tumour is called “SMARCA4-deficient” because it lacks a functional SMARCA4 gene, which normally helps regulate how cells grow and develop. What are the symptoms …

A carcinoid tumourlet is a small, non-cancerous growth found in the lungs. It is made up of special cells called neuroendocrine cells. Neuroendocrine cells are normally found throughout the lungs, especially in the airways. When these cells group together and grow slightly more than normal, they can form tiny structures called tumourlets. To be called …

Minimally invasive adenocarcinoma (MIA) is an early type of lung cancer. It is called “minimally invasive” because the tumour cells have just started to spread into the lung tissue around the small air spaces, called alveoli. To be classified as minimally invasive, the tumour must be smaller than 3.0 centimeters, and the area where the …

Adenocarcinoma in situ (AIS) is a type of early-stage, non-invasive lung cancer. The term non-invasive refers to the fact that the cancer cells have not spread beyond the inner lining of the small air sacs (alveoli) within the lungs. To be classified as adenocarcinoma in situ, the tumour must be no larger than 3.0 centimeters …

An atypical carcinoid tumour is a type of lung cancer. It develops from special cells in the lungs called neuroendocrine cells. These cells normally produce hormones that help regulate breathing and airflow in the lungs. Atypical carcinoid tumours usually grow in the central area of the lung near the airways. When the tumour grows large …

What is a typical carcinoid tumour of the lung? A typical carcinoid tumour is a slow-growing type of lung cancer made up of neuroendocrine cells. In the lung, this tumour starts from the neuroendocrine cells normally found in the walls of the airways and is often located in the central part of the lung near …

What is usual interstitial pneumonia? Interstitial pneumonia is a group of diseases where inflammation and fibrosis damage small air-filled spaces inside the lungs called alveoli. Over time, the damage leads to scarring which prevents the lungs from working properly. Although the word pneumonia is used, this does not mean there is an infection in the …

Squamous cell carcinoma (SCC) is a type of non-small cell lung cancer. The tumour starts from specialized squamous cells that are normally found on the inside of the airways of the lungs. These cells form a barrier called the epithelium which helps protect the airways from damage. SCC of the lungs can be keratinizing (KSCC), …
