Staging lung cancer is based on whether the cancer is local or has spread from the lungs to the lymph nodes or other organs. Because the lungs are large, tumors can grow in them for a long time before they are found. Even when symptoms—such as coughing and fatigue—do occur, people think they are due to other causes.
Read now Staging The staging of cancer indicates how far it has spread through the body and its severity. This classification helps clinicians support and direct treatment for the best results. Each stage determines whether cancer has or has not spread or has spread to nearby lymph nodes.
It may also take into account the number and size of the tumors. The lymph nodes are part of the lymphatic system, which connects to the rest of the body. If cancer reaches these, it can metastasize, or spread further, becoming more dangerous.
Staging for lung cancer is extremely complex and extensive with several sub-groups within each stage. Initially, clinicians divide it into small cell and non-small cell classifications. Staging definitions may vary, but doctors typically stage non-small cell lung cancer using the tumor size and the spread to guide them in the following way: Cancer does not show on imaging scans, but cancerous cells might appear in the phlegm or mucus and may have reached other parts of the body.
The doctor finds abnormal cells only in the top layers of cells lining the airways. A tumor has developed in the lung, but is under 5 centimeters cm and has not spread to other parts of the body. The tumor is smaller than 5 cm and might have spread to the lymph nodes in the area of the lung, or smaller than 7 cm and spread to nearby tissues but not lymph nodes.
Cancer has spread to the lymph nodes and reached other parts of the lung and surrounding area. Cancer has spread to distant body parts, such as the bones or brain.
Small cell lung cancer has its own categories, limited and extensive, referring to whether cancer has spread within or outside the lungs.
Treatment Treatments for lung cancer depend on its location and stage, as well as the overall health of the individual. Surgery and radiation are the most common approaches to treating lung cancer, but other treatments are available. For example, doctors often treat small cell lung cancer with chemotherapy.
A doctor may operate to remove cancerous lung tissue and tissue in the surrounding areas where cancer may have spread. This sometimes involves removing a lobe or large segment of the lung in a procedure called a lobectomy.
In severe cases, the surgeon may remove a lung in its entirety. A person can live without a lung, but being in good health prior to surgery helps to improve outcomes after lung removal.
This treatment uses drugs to shrink or eradicate cancer cells. These medications target rapidly dividing cells, which makes them ideal for treating cancer. Chemotherapy treatment has a more significant impact on cancers that have spread to different parts of the body and require a body-wide attack.Learn More About Cancer Types.
There are more than types of cancer. Types of cancer are usually named for the organs or tissues where the cancers form, but they also may be described by the type of cell that formed . Types and Staging of Lung Cancer. There are two major types of lung cancer, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).Staging lung cancer is based on whether the cancer is local or has .
Lung cancer can be broadly classified into two main types based on the cancer's appearance under a microscope: non-small cell lung cancer and small cell lung cancer.
There are two main types of primary lung cancer. They behave in different ways and respond to treatment differently. They are: non-small cell lung cancer (NSCLC), the most common type small cell lung cancer (SCLC), which makes up about 10% of lung cancers (1 in 10). Adenocarcinoma is the most common. Types and Staging of Lung Cancer. There are two major types of lung cancer, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).Staging lung cancer is based on whether the cancer is local or has . Types. Find out about the different types of lung cancer. The most common type is non small cell lung cancer. The type of lung cancer you have tells you the type of cell that the cancer started in. Knowing this helps your doctor decide which treatment you need.
In this example, cancer begins in breast tissue, not lung tissue, and would be referred to as breast cancer metastatic to the lungs, rather than lung cancer.
There are many types of cancer that can metastasize to the lungs, with the most common being breast cancer, . Non-small cell lung cancer is the most common type of lung cancer. About 85% of lung cancers are non-small cell lung cancers. Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma are all subtypes of non-small cell lung cancer.
People's experiences of these rarer types of lung cancer will generally be similar to those of people with more common forms of the condition. However, there are some differences in treatment and outlook.
