What is the difference between small cell carcinoma and non small cell carcinoma?

What is the most aggressive lung cancer?

SCLC is the most aggressive form of lung cancer. It usually starts in the breathing tubes (bronchi) in the center of the chest. Although the cancer cells are small, they grow very quickly and create large tumors.

Which type of lung cancer has the best prognosis?

It is increasing in frequency and is more common in women. People with this type of lung cancer tend to have a better prognosis than those with other types of lung cancer. Squamous cell carcinomas were formerly more common than adenocarcinomas; today, they account for about 25% to 30% of all lung cancer cases.

What is the survival rate of non-small cell carcinoma?

The 5-year survival rate for NSCLC is 25%, compared to 7% for small cell lung cancer. However, it is important to note that survival rates depend on several factors, including the subtype of lung cancer, and the stage of disease.

What is the life expectancy of someone with stage 4 lung cancer?

Stage 4 lung cancer is the most advanced stage of lung cancer. In stage 4, the cancer has spread (metastasized) to both lungs, the area around the lungs, or distant organs.

What are the survival rates for stage 4 lung cancer?

Stage 5-year survival rate
All stages combined for non-small cell lung cancer 25 percent

How long can you live with stage 4 non-small cell lung cancer?

Stage 4 lung cancer usually has a poor prognosis. One study found that depending on the stage of the metastases (spread) the average survival time following diagnosis of stage 4 lung cancer ranged from 6.3 months to 11.4 months.

What is the main cause of small cell lung cancer?

Tobacco smoking1 is by far the leading cause of small cell lung cancer (SCLC). Most small cell lung cancer deaths are caused by smoking or exposure to secondhand smoke. Smoking is clearly the strongest risk factor for lung cancer, but it often interacts with other factors.

Can you have lung cancer for years and not know it?

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. For example, it takes around eight years for a type of lung cancer known as squamous cell carcinoma to reach a size of 30 mm when it is most commonly diagnosed.

Which type of lung cancer is most likely to metastasis?

Stage 4 is the most advanced form of lung cancer and is metastatic—meaning the cancer has spread from the lung, where it originated, into other parts of the body. Metastasis occurs when cancer cells separate from the original tumor and move through the body via the blood or lymph system.

What happens after 5 year survival rate?

Beyond recurrence for the original cancer, other common post-five-year survival issues include anxiety and depression, second cancers (for example, leukemia as a result of radiation) and a variety of other possible late effects from therapy.

How long can you live with Stage 4 squamous cell carcinoma?

For a patient with stage IV cancer, age must also be considered to prognose survival. For a patient who is 67 years or older, the expected median survival is a little more than 1 year. If this patient were younger than 67 years, then the expected median survival would be about 2 years.

Is non-small cell carcinoma fatal?

Non-small cell lung carcinoma is a type of lung cancer, also commonly referred to as non-small cell lung cancer (NSCLC). NSCLC can cause breathing difficulties and ultimately cause health complications. If diagnosed late or left untreated, it can be life threatening.
