What is Stage 3B Lung Cancer

What is Stage 3B Lung Cancer

Stage 3b lung cancer - may not yet know "what is stage 3b lung cancer" and can stage 3b lung cancer go into remission. Therefore, we will discuss the matter with survival rate and prognosis of lung cancer that we know, as well as a life expectancy that is quite clear that we gave some time ago. The lungs are the organs occupying the majority of the chest, one on the left and one on the right, the right lung is divided into three upper lobes, the middle lobe, the lower lobe, the left lung is divided into the upper lobe and the lower lobe. In the lungs, the bronchi spread like a branch of a tree, and there is an alveolus at the end. 

In the middle of the chest between the right lung and the left lung is a space called the mediastinum (heart), there are multiple organs such as the heart, large blood vessels, trachea, esophagus and so on. Organs in the lungs and mediastinum are covered with a membrane called the pleura (visceral pleura). Likewise, the inner wall of the thorax surrounded by ribs (thoracic cavity) is also covered with the pleura (parietal pleura). 

The lungs take on oxygen into the body and play an important role in releasing carbon dioxide. what is stage 3b lung cancer - Oxygen is sent to the alveoli by respiration and is taken into the blood. In addition, carbon dioxide in the blood is discharged to the alveoli and is expired by breathing.

Lung cancer is a cancerous bronchial or alveolar cell that has been caused by some cause. As it progresses, cancer cells proliferate while destroying surrounding tissues and spread the flow of blood and lymph fluids. Places that are easy to metastasize are lymph nodes, brain, liver, adrenal glands, and bones.

Symptom: Lung cancer is almost asymptomatic at an early stage. Respiratory symptoms such as a cough, sputum, bloody sputum, fever, dyspnea, chest pain, etc. will appear as the disease progresses. However, because these are not necessarily unique to lung cancer, they may be indistinguishable from other respiratory diseases. If multiple symptoms are seen or prolonged and you are concerned, it is important to consult a medical institution earlier. 

In addition, there are symptoms caused by the tumor producing special substances or by the influence of the immune reaction. what is stage 3b lung cancer - They are called "tumor associated syndrome", and it develops relatively more in lung cancer than other cancers. Symptoms include obesity, moon face (face is rounded like a full moon), anorexia, neurologic symptoms, disturbance of consciousness and so on. 

In addition, there are cases where symptoms are rarely seen irrespective of the degree of progression, and it may be found by chest X-ray examination such as examination or CT examination. Because smoking is very related to lung cancer, people with a history of smoking who are 40 years of age or older need to pay special attention even if they do not have symptoms.

The number of newly diagnosed lung cancer is 88.7 per 100,000 people a year. The prevalence rate by age starts to increase from the late 40s and becomes higher as older. In terms of male and female prevalence rates, males are more than twice as likely as women.

Stage 3B Lung Cancer Prognosis

We will classify lung cancer progression by stage. The stage is a measure to evaluate uniformly how much cancer is spreading. It is important to have uniform standards to evaluate the progress of the disease. Treatment regimens for cancer are determined based on the stage.

The stage is divided into Stage I to Stage IV. For lung cancer, I will divide it more like IA, IB. Internationally it is usual to write in Roman numerals (III, etc.), but there are also places listed on this site by Arabic numerals (3 etc.). There is no need to remember the classification criteria to receive treatment. However, stage classification is very important in determining the treatment method. Also, it is easier to understand how your cancer is progressing and how you cannot receive surgery by fitting your situation to stage classification. What is stage 3b lung cancer - Next, I will explain why stage classification is important.

At this stage, tumors have a width greater than 3 cm and have spread into the lymph nodes in the center of the thorax or in other structures outside the lung. In stage III lung cancer, the affected lymph nodes are restrained on the same side of the body as the tumor. Stage III of lung cancer is classified either as stage IIIA or IIIB, depending on the size and location of the tumor and how far it has spread.

Approximately 30% of patients determined to have lung growth are at organize III at the season of determination. The five-year survival rate for stage IIIA lung cancer varies greatly and is approximately 23% on average. For lung cancer in the IIIB stage, the survival rate is approximately 10%.

For many types of stage IIIA cancer and almost all cancers of the stage IIIB, the tumor can be difficult and sometimes impossible to remove. For example, the tumor may spread out of the lung to the located lymph nodes in the center of the chest. Or cancer can spread into structures near the lung. In both cases, the thoracic surgeon may not be able to remove all cancer cells and recommend chemotherapy combined with radiation treatments before considering surgery.

What is distant metastasis? Cancers, as well as lung cancer, cause distant metastasis. Distant metastasis refers to the transfer of cancer cells to distant organs as the name implies. Since all organs receive nutrition from the blood flow, when cancer cells invade into the blood, cancer cells arrive in all the organs theoretically. However, it does not mean that metastasis always occurs, even if the cancer cells reach the organs. What is it?  

As cancer cells reach all organs, including lymph nodes, immune cells come up and work to eliminate cancer cells. However, if the balance between the momentum of the cancer such as the amount of cancer cells and the degree of malignancy and the force of the immune cell tilt towards the momentum of cancer, cancer cells will settle in the organs and cause metastasis.

Actually, the balance between cancer cells and immune cells is a very complicated story. We carve cancer cells so that they are not attacked by human immunity. Drugs (nivolumab, pembrolizumab, etc.) that keeps it from occurring have been drawing attention recently. What is stage 3b lung cancer - Most anticancer drugs to date kill direct cancer cells, but normal and others are medicines to support immune cells that eliminate cancer.

What is the stage of 6 cm lung cancer? For example, suppose that there is a tumor of lung cancer 6 cm. What is the stage of this lung cancer? This answer will be over stage IIB. If lung cancer size is 6 cm and it does not influence anywhere including the pleura, it becomes T3. However, in order to decide the stage of cancer, it is necessary to evaluate the status of metastasis to lymph nodes and distant metastasis, not just the size of the cancer. For example, if the size of the cancer is distant metastasis even at 6 cm T 3, the stage will be IV. In other words, in order to judge the degree of cancer progression, it is necessary to comprehensively judge not only the size of cancer but also the transition status to lymph and organs.

Depending on the stage of lung cancer, you can see the average life expectancy to some extent. What is stage 3b lung cancer - Nonetheless, I do not know if the average number applies to me, and the numbers will change according to the treatment, so I can not say a certain thing. There are many data on life expectancy in the treatment of lung cancer, but some numbers are fluctuating according to the report. The number will naturally change depending on the contents of treatment and physical strength of the patient, so it is better to think that the average life expectancy is approximate.
