5-Year survival rates for lung cancer
- About 17% overall.
- 54% for cases when the disease is limited to the lungs.
- 27% if the lung cancer has spread to nearby organs or lymph nodes.
- 4% if cancer has spread to distant organs, such as the liver.
|Lung cancer spread/status||Survival rate|
|Spread to both lungs||54%|
|Spread to nearby organs or lymph nodes||27%|
|Spread to distant organs such as the liver||4%|
The 5-year survival rate for lung cancer when the disease is localized to one lung is about 60%. However, getting diagnosed at an early stage is extremely rare. Most lung cancers are diagnosed at a more advanced stage, where the survival rate is about 20%. More than half of lung cancer patients die within one year of being diagnosed because the cancer is aggressive, lethal, and often only detected at the advanced stages.
Chances of survival after lung cancer diagnosis depend on the type of lung cancer, age, staging, and whether there is a history of smoking or other comorbidities (presence of other diseases). Therefore, survival rates are determined on a case-by-case basis.
- If lung cancer is diagnosed at an early stage, the disease may be curable with surgery, radiation, or chemotherapy.
- However, if diagnosed at an advanced stage, the disease is typically incurable, and chances of survival decrease if cancer has spread to other organs or lymph nodes.
What are the survival rates for each stage of lung cancer?
Non-small cell lung cancer (NSCLC)
NSCLC is the most common type of lung cancer, accounting for 80-90% of the cases. The 5-year survival rates for NSCLC are:
- Stage I
- Stage IA: 59-73%
- Stage IB: 43-58%
- Stage II
- Stage IIA: 36-46%
- Stage IIB: 25-36%
- Stage III
- Stage IIIA: 19-24%
- Stage IIIB: 7-9%
- Stage IV
- Survival rates of stage IV NSCLC are extremely low.
Small cell lung cancer (SCLC)
SCLC makes up about 20% of all lung cancer cases and typically occurs in people who smoke or who used to smoke. The cancer forms in the airway, usually in a central location. SCLC is aggressive, spreading quickly throughout the body using the blood and lymphatic (lymph node) systems. The 5-year survival rates for SCLC are:
- Stage I
- Stage IA: 40%
- Stage IB: 20%
- Stage II
- Stage IIA: 40%
- Stage IIB: 20%
- Stage III
- Stage IIIA: 15%
- Stage IIIB: 10%
- Stage IV
- Lung cancer tends to get diagnosed only in the late stages. At stage IV, the cancer has usually already metastasized to a great extent.
In general, people diagnosed with NSCLC tend to have a slightly better outlook than people with SCLC.
Most people who die of lung cancer are middle-aged or older, and the percentage of lung cancer deaths is the highest among people 65-74 years of age. Overall health can also make a difference. For example, staying physically active and avoiding tobacco smoke after lung cancer treatment can lower the risk of cancer recurrence, according to the Centers for Disease Control and Prevention (CDC).
Though lung cancer remains an extremely deadly type of cancer, there is great hope on the horizon to reduce the fatalities associated with this disease.

How Long Does Lung Cancer Take to Develop?The time taken for lung cancer to develop is variable. It takes several years for cancer to develop in the lungs. Early lung cancer does not alert obvious physical changes. Moreover, patients can live with lung cancer for many years before they show any signs or symptoms.
Lung CancerLung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due to tobacco smoke. Lung cancers are classified as either small-cell or non-small-cell lung cancers.

Small Cell Lung Cancer vs. Non-Small Cell Lung CancerNon-small cell lung cancers (NSCLC) consist of large cell carcinomas, adenocarcinomas, and squamous cell carcinomas. Small cell lung cancer (SCLC) usually starts in the bronchi and typically appears in those who smoke. SCLC and NSCLC are staged in different manners, and SCLC tends to metastasize more quickly than NSCLC. Signs and symptoms of NSCLC and SCLC include shortness of breath, coughing up blood, recurring lung infections, and chest pain. Treatment may involve radiation therapy, chemotherapy, and surgery.
Six Early Signs of Lung CancerLung cancer is the third most common cancer in the United States. It may not show its signs and symptoms in its early stages. Signs and symptoms typically appear in the advanced stage of the disease.
What Are the Four Types of Lung Cancer?The four types of lung cancer are classified by what kind of cells the cancer affects and what the tumor cells look like under a microscope. Lung cancers can be small-cell or non-small cell, further classified as squamous cell carcinoma or adenocarcinoma.
What Does Lung Cancer Feel Like When It Starts?Lung cancer refers to the uncontrolled growth of cells that starts in the lungs. Lung cancer occurs when any of the several cells in the lungs undergo an abnormal change in its genetic code. This change is called a mutation.
What Is the Survival Rate of Non-Small Cell Lung Cancer?There are two main types of lung cancers, namely, small cell lung cancer and non-small cell lung cancer (NSCLC). NSCLC accounts for 85% of all lung cancer cases in the United States. It must be noted that medical science is progressing with leaps and bounds, and treatment for lung cancer must be initiated and maintained despite the stage of diagnosis.
What Is Usually the First Sign of Lung Cancer?Most often, lung cancer does not show any signs and symptoms until it has advanced to higher stages when it becomes difficult to treat. The initial signs and symptoms vary among patients but may include cough that remains unrelieved and gets worse over time, hemoptysis (coughing up blood) or reddish spit, chest pain that worsens on breathing or laughing, hoarseness of voice, weight loss, persistent chest pain, and frequent lung infections.
Will a Chest X-Ray Show Lung Cancer?When diagnosing lung cancer, chest X-rays do not provide a definitive diagnosis of lung cancers at an early stage (when they are more treatable). Until the lung cancer shows up on a chest X-ray, the tumor is often too far advanced to be cured. Often, many things seen on a chest X-ray turn out to be treatable problems or artifacts.
