Understand how lung cancer staging works

Lung cancer can be divided into two main types: small cell lung cancer and non-small cell lung cancer (NSCLC).As much as possible 85 percent Among the cases of lung cancer, it is NCSLC.

The five common stages of lung cancer are numbered from 0 to 4.

• Stage 0 Indicates a small tumor that has not spread to deeper lung tissue. Doctors also call this carcinoma in situ (CIS).
• Stage 1 Lung cancer is limited to the lungs and has not spread to the lymph nodes.
• Stage 2 Lung cancer may have spread to nearby lymph nodes.
• Stage 3 Lung cancer has spread further to the lymph nodes and in the center of the chest.
• Stage 4 The cancer has spread to both lungs, fluid around the lungs, or another part of the body.

Lung cancer can also be detected in a sample before it appears as a tumor. This is known as “potential” or “hidden” cancer.

At each general stage, numbers and letters (A or B) are also retrieved. Cancers with a small number or letter A are less widespread than cancers with a large number or letter B.

Doctors use a grouping system called TNM based on the following to stage lung cancer.

• tumor (T): The size of the major tumor in the lung and whether it has grown into nearby structures or organs.
• node (N): Whether the cancer has spread to nearby lymph nodes.
• Metastasis (M): Has the cancer spread (metastasis) to distant sites such as the liver or brain?

The numbers after each of these letters also indicate how far the cancer has spread. The higher the number, the greater the spread.

Together, stages and stage grouping tell your doctor where your cancer is in your body. People with the same stage and stage group usually receive the same treatment. This staging is commonly used for NSCLC.

Common lung cancer stages

Stage of small cell lung cancer

Small cell lung cancer is diagnosed as either localized or broad-stage. Your doctor may also use the TNM staging system.

Localized lung cancer has reached only part of the chest.

Lung cancer in a wide range of stages may have spread to the lymph nodes or other parts of the body.

Lung cancer can be cured if detected early. The cure rates for stage 0 and stage 1 lung cancer are as follows: 80 to 90 percent..People often receive diagnose When their lung cancer is late.

When the cancer spreads, it becomes difficult to cure. Treatment can be delayed, but it cannot be stopped.Immunotherapy Prolonging the survival of NSCLC patients More than people taking a standard course of chemotherapy.

New treatments are improving the outlook for lung cancer patients.You may be able to try one of these treatments by registering with Clinical trial..

Treatment of lung cancer depends on the stage of the disease.

Stage 0 lung cancer is usually cured by surgery to remove part of the leaf in one lung. This surgery is called wedge resection or partial resection.

Stage 1 lung cancer Surgery To remove part of the affected lung lobe (lobectomy) or the entire lobe. Chemotherapy or radiation therapy may be given after surgery to prevent the cancer from recurring.

Treatment of stage 2 lung cancer also includes surgery to remove the leaves or the entire lung. All lymph nodes that may contain cancer are also removed. Chemotherapy or radiation therapy may be given after surgery to remove the cancer cells that remain after surgery.

Stage 3 may include surgery if the doctor thinks the cancer can be removed. This is usually done with chemotherapy, radiation therapy, immunotherapy, or in combination with multiple of these treatments.

Stage 4 lung cancer is already widespread by the time it is diagnosed. Surgery to remove a spread tumor may be part of your treatment. You may also receive systemic treatments such as chemotherapy, immunotherapy, and targeted therapy.

The staging system shows the size of lung cancer and where it has spread in the body. Knowing the stage of your cancer can help your doctor find the right treatment and inform you of your outlook.

Talk to your doctor if you have any questions about what it means for your stage or prognosis. Late-stage cancer can cause fear and anxiety. If you are experiencing these feelings, seek help and support from your therapist or counselor.
