One of the most prevalent and dangerous kinds of cancer in the world is lung cancer. Patients and their families can make better decisions about evaluation and treatment if they understand its stages. This article will talk about the different stages of lung cancer and how it can be found with tools like a lung scan. You will also learn about the different ways it can be treated at each step. We will also talk about the part that PSA levels play in the care and tracking of cancer.

Stages of Lung Cancer

Lung cancer is divided into stages depending on how far it has spread. These stages help doctors to figure out the best way to treat the patient.

• Stage 0: Carcinoma in situ

Cancer cells are present at this early stage, but they haven't yet spread to other parts of the body or into lower lung regions. Since symptoms are rare, it is important to get regular screenings like lung scans to find the disease early.

• Stage 1: Localized Cancer

There is no lymph node involvement in stage I lung cancer because it is only in the lungs. Usually, surgery is used to remove the tumor, and if that doesn't work, radiation or chemotherapy is then used.

• Stage II: Regional Spread 

At this point, the lung cancer has spread to nearby lymph nodes or tissues, but it is still inside the chest. Chemotherapy or radiation is often used along with surgery to kill any cancer cells that are still alive.

• Stage III: Locally Advanced

Lymph nodes or nearby structures have been affected by stage III lung cancer. It gets harder to treat, and it usually takes more than one type of medicine, like tailored treatments and immunotherapy.

• Stage IV: Metastatic Cancer 

Once the cancer has spread to other parts of the body, like the brain, bones, or liver, it is in the fourth stage. It is less likely that there will be a fix, but medicines like chemotherapy, immunotherapy, and hospice care can make life better and increase the time people can live.

Treatment Options for Lung Cancer

Treatment depends on the stage and type of lung cancer, as well as the patient’s overall health.

• Surgery:

Most of the time, surgery is the best way to treat early-stage lung cancer because the tumor can be taken out completely.

• Radiation Therapy:

High-energy rays are used in radiation to kill cancer cells. It's often used along with surgery or for people who can't have surgery.

• Chemotherapy:

Drugs are used in chemotherapy to kill cancer cells. It works especially well for cancers that are in their later stages or are very irritable.

• Immunotherapy:

Immunotherapy trains the immune system to find cancer cells and fight them. It has been very successful in recent years and is often used for lung cancer treatment.
