Overall Survival Rates By Type
There are two basic types of lung cancer: small cell , the most aggressive type of lung cancer, and non-small cell , the most common type .
- Small cell lung cancer: The overall 5-year survival rate for small cell lung cancer is about 6.7%.
- Non-small cell lung cancer: The overall 5-year survival rate for NSCLC is approximately 26.3%.
- Bronchioloalveolar carcinoma : A type of NSCLC, BAC is actually an older term and is now considered a subtype of lung adenocarcinoma. The survival rate with BAC is significantly better than with other forms of NSCLC, especially when it is caught early and only one tumor is present. According to research, there is a five-year overall survival rate of 98% after surgery for those with minimally invasive adenocarcinoma . The five-year survival rate for people with more advanced stages of the disease varies considerably.
Early Symptoms Of Lung Cancer
Back pain can occur when tumors cause pressure in your lungs or when they spread to your spinal cord and ribs.
Other early signs of lung cancer may include:
- a lingering or worsening cough
- coughing up phlegm or blood
- chest pain that worsens when you breathe deeply, laugh, or cough
- some petroleum products
Research shows that inherited genetic mutations may make you more likely to develop lung cancer, especially if you smoke or are exposed to other carcinogens. Sometimes, theres no obvious cause for lung cancer.
Stage 3c Lung Cancer: Spread Throughout Chest
Stage 3C lung cancer has spread to all or part of the chest wall or its inner lining, the phrenic nerve, or the membranes of the sac that surrounds the heart.
Cancer has also reached stage 3C when two or more separate tumor nodules in the same lobe of a lung have spread to nearby lymph nodes. In stage 3C, the lung cancer has not spread to distant parts of the body.
Like stage 3A, stages 3B and 3C cancer may have spread to other chest structures. Part or all of the lung may become inflamed or collapse.

Talk To Your Doctor To See If Screening Is For You
You should be screened at an accredited facility.
Conversations between physicians and patients about lung cancer screening should include a discussion of the risks of abnormal findings and of subsequent courses of action, such as the potential adverse events associated with surgical intervention or other invasive diagnostic procedures.

Small Cell Lung Cancer Is A More Aggressive Type Of Lung Cancer And It Has A Poorer Prognosis:
- Localized spread has a five-year survival rate of 27%
- Regional spread has a five-year survival rate of 16%
- Distant spread has a five-year survival rate of 3%
Even non-small cell has cell subtypes with different prognoses. For example, adenocarcinoma is a type of non-small cell, and it tends to have a slightly better prognosis than other forms.
A 2011 study reported that adenocarcinoma patients lived a median of 8.4 months while all other non-small cell lung cancer patients lived a median of 8.1 months. While the difference is small, researchers have found similar results in other studies and believe the lung cancer statistics are significant.

Stages Of Lung Cancer Survival Rate And Prognosis
Lung cancer has progressed from an obscure disease to one of the most common cancer in the world. Lung cancer is divided into various stages
- Localized disease
- Regional disease, and
- Advanced disease.
Early cancer is a stage 1 and 2 lung cancer regional cancer is stage 3 lung cancer and advanced cancer is stage 4 cancer. Patients with stage 1 and 2 lung cancer will have a good prognosis. Stage 3 lung cancer is intermediate, and the lymph nodes are involved. Stage 4 lung cancers are advanced cancer.
Once the patient is diagnosed with lung cancer, the next step will be staging. Staging helps doctors in predicting the prognosis of the patient and helps in deciding the treatment plan, which is a very important step.
Types of lung cancer:
Lung cancer is divided into types small cell lung cancer and non-small cell lung cancer. These two types of cancer comprise about 95% of all lung cancers, the remaining 5% are very rare tumors.
- Small Cell Lung Cancer : mainly occur in the central part of the lung and these are aggressive tumors that spread very fast. Small cell lung cancers are mainly staged in two types. i) Limited stage SCLC and ii)extensive SCLC. SCLC comprises only 10% of all lung cancer and apart from this 80 to 90% of lung cancers are non-small cell lung cancer.
- Non-Small Cell Lung Cancer : They are staged by Tumor lymph Node Metastasis staging, in which cancer has spread to other parts of the body.

What Causes Small Cell Lung Cancer
The exact cause of lung cancer isnt known. However, its believed that precancerous changes in the lungs can lead to cancer. These changes affect the DNA of cells inside the lungs, causing lung cells to grow faster.
Too many changes can cause the cells to become cancerous. Blood vessels feed the cancer cells, allowing them to grow into tumors.
Over time, cancer cells may break away from the primary tumor and spread to other parts of the body.
Stage 3a Versus 3b Non
Stage 3 non-small cell lung cancer is subdivided into 3A and 3B. Stage 3A refers to cancer that has spread to the lymph nodes in the chest, but only on the same side as the affected lung. Stage 3B refers to cancer that has spread to the neck or lymph nodes on the other side of the chest, or to other organs. Although stage 3A cancer has spread, it has a better prognosis than 3B because it has not spread as far.
Life expectancy with cancer is broken down into overall survival after a set number of years. A large study of over 81,000 patients with lung cancer found 19% to 24% of patients with stage 3A and 7% to 9% of patients with stage 3B were alive five years after they were diagnosed. And according to the American Lung Association, the five-year survival rate for lung cancer overall is 55% if it is diagnosed when it is still confined to the lungs. However, once it has reached stage 3 and has begun to spread, the five-year survival rate ranges between 4% and 16%, depending on how much it has spread.

Characteristics Of Stage 2 Lung Cancers
Lung cancer staging is a process used to classify the severity of the disease. The staging of non-small cell lung cancer utilizes the TNM system, which determines the cancer stage based on the tumor’s size and extent , whether nearby lymph nodes have cancer cells in them , and if there is evidence of the spread of cancer, also known as metastasis .
The cancer stage helps directs the appropriate course of treatment as well as predict the likely outcome .
Stage 2 NSCLC is broken down into two substages:
- Stage 2a lung cancer indicates a tumor size of between 4 and 5 centimeters . The tumor may also have grown into an airway or tissues surrounding the lungs. However, no lymph nodes will be affected, and there will be no evidence of metastasis.
- Stage 2b lung cancer indicates that the tumor is either less than 3 centimeters in diameter and has spread to nearby lymph nodes, or that the tumor is between 3 and 5 centimeters or may have spread into the airways or surrounding tissues as well as nearby lymph nodes. There will also be no evidence of metastasis.
Additional Lung Cancer Prognostic Predictors
More and more factors emerged as independent lung cancer survival predictors in the recent decade. The importance of pathologic markers such as tumor size, cell type, lymphatic and blood vessel invasion, rate of proliferation and ploidy, and extent of tumor necrosis is apparent but inconsistent. Following is a highlight on the current knowledge of selected survival predictors beyond disease stage, treatment, and patient gender.17
Tumor Cell Differentiation
In a study of 5,018 hospital-based patients and 712 population-based patients, tumor grade was found to be significantly associated with survival after adjusting for the effects of age, gender, smoking history, tumor stage, histological cell type, and treatment modality. Patients with poorly/undifferentiated carcinoma had a 70% elevated risk of death compared to those with well differentiated carcinoma. A 40% elevated risk was observed for patients with moderately differentiated carcinoma.18
In a study of 5,229 patients with NSCLC and SCLC, the median survival time among never, former, and current smokers with NSCLC was 1.4 years, 1.3 years, and 1.1 years, respectively . Female NSCLC patients had a significantly lower risk of mortality with a longer duration of smoking abstinence. Specifically, the relative risk per 10 years of smoking abstinence is 0.85, supporting a direct biologic effect of smoking on survival.19

Small Cell Lung Cancer
10 to 15 percent of people with lung cancer, according to the ACS.
SCLC is more aggressive than NSCLC and can spread quickly. Its also sometimes called oat cell cancer based on the way cells look under a microscope.
Doctors assign stages to SCLC using two different methods.
The most formal way of assigning stages is the TNM staging system described in the NSCLC section above.
More commonly, SCLC is staged by classifying the cancer as:
- Limited. The cancer is only on one side of the chest and in a limited, defined area.
- Extensive. The cancer has spread throughout the lung, to the other lung, to lymph nodes on the other side of the chest, or to other parts of the body.
As in staging NSCLC, your doctor will do a physical exam and order various tests to determine the stage of your SCLC.
Because the systems for staging lung cancer are complex, its best to ask your doctor to explain your stage and what it means for you.
Early detection is the best way to improve your outlook, especially as treatments improve.
likely to receive a diagnosis of lung cancer than men in the United States, but men are more likely to die from it.
The ACS estimates that 117,910 men and 118,830 women will receive a lung cancer diagnosis in the United States in 2022. To put these numbers into perspective, the chance that a man will develop lung cancer in his lifetime is 1 in 15. For women, that chance is 1 in 17.
The number of predicted deaths in 2022 is lower than it was in 2021.
Risk Factors For Lung Cancer
There are multiple known risk factors for lung cancer. These include:
- Smoking: Smoking is the single biggest risk factor for lung cancer. This includes cigarettes, cigars, and pipes. Tobacco products contain thousands of toxic substances. According to the
9 out of 10 lung cancers. Plus, you dont have to be a smoker to be affected. Secondhand smoke also increases your risk of lung cancer.
In addition to cigarettes, cigar and pipe smoking are also linked to lung cancer. The more you smoke and the longer you smoke, the greater your chance of developing lung cancer.
Former smokers are still at risk of developing lung cancer, but quitting can lower that risk considerably. Within 10 years of quitting smoking, the risk of dying from lung cancer drops by half.

Interpreting Lung Cancer Survival Rates
Lung cancer is a very serious type of cancer and is often fatal. But thats slowly changing as research advances.
People who receive a diagnosis of early-stage lung cancer are surviving in growing numbers. According to the American Lung Association, about 541,000 people who received a lung cancer diagnosis at some point are still alive today.
If you receive a lung cancer diagnosis, your doctor may talk with you about probable survival rates. This number is a statistic based on large numbers of people with the same type and stage of cancer.
Your experience may be different. Your healthcare team can give you the best idea of what to expect based on your individual circumstances.
Lung Cancer Life Expectancy And Survival Rates
Since life expectancy is based on the individual patient, the survival rate is best mentioned as an average. If youre diagnosed with lung cancer, youll get a specific prognosis on life expectancy from your oncologist. Research from the American Lung Association suggests that for lung cancer, the average five-year survival rate is approximately 18.6 percent. This means that about 18.6 percent of patients diagnosed with lung cancer survive five years after their diagnosis. This specific rate percentage averages all stages and types of cancer together. When the demographics and other specifics are broken down, the survival rate changes. For instance, if you only averaged stage one and stage two together, the survival average will be higher, since lung cancer treatments have more favorable outcomes on earlier stage lung cancer than in later stages.
Non-Small Cell Lung Cancer
This is the most common type of lung cancer. Approximately 80 percent of people with the disease have NSCLC. The five-year survival rate for this subtype when tumors have metastasized to other parts of the body is approximately seven percent. If tumors have only reached nearby tissue, then the rate jumps up to 35 percent. When tumors are localized, meaning they havent spread at all, the five-year survival rate is approximately 63 percent.

Survival Statistics For Small Cell Lung Cancer
Survival statistics for small cell lung cancer are very general estimates and must be interpreted very carefully. Because these statistics are based on the experience of groups of people, they cannot be used to predict a particular person’s chances of survival.
There are many different ways to measure and report cancer survival statistics. Your doctor can explain the statistics for small cell lung cancer and what they mean to you.
Lung Cancer Life Expectancy With Treatment
Treatment typically enhances the life expectancy of lung cancer patients. Stage 4 is considered advanced, meaning it is often not curable, and treatment can do very little to help. Nevertheless, patients may choose to undergo surgery to remove the tumors, chemotherapy, radiation, or another form of therapy. Individual responses to treatment influence the life expectancy of lung cancer patients.
Medical professionals often urge stage 4 lung cancer patients to transition to palliative care instead of typical treatment. Advanced lung cancer can become painful, so palliative care is a type of treatment that focuses on relieving lung cancer symptoms. Examples of palliative care include:
- Pain management or suppression medicine
- Counseling and emotional support

Prognosis And Survival For Lung Cancer
If you have lung cancer, you may have questions about your prognosis. A prognosis is the doctor’s best estimate of how cancer will affect someone and how it will respond to treatment. Prognosis and survival depend on many factors. Only a doctor familiar with your medical history, the type and stage and other features of the cancer, the treatments chosen and the response to treatment can put all of this information together with survival statistics to arrive at a prognosis.
A prognostic factor is an aspect of the cancer or a characteristic of the person that the doctor will consider when making a prognosis. A predictive factor influences how a cancer will respond to a certain treatment. Prognostic and predictive factors are often discussed together. They both play a part in deciding on a treatment plan and a prognosis.
The following are prognostic and predictive factors for lung cancer.
What Affects Survival
Your outcome depends on the type of lung cancer that you have and also the stage of the cancer when it was diagnosed. This means how big it is and whether it has spread.
Your general health and fitness might also affect survival. Doctors call this your performance status. A score of 0 means you are completely able to look after yourself. A score of 1 means you can do most things for yourself but need some help. The scores continue to go up, depending on how much help you need. People with a higher score may have a poorer outlook.
