Frequent question: What kind of cancer is small cell carcinoma?

Can you survive small cell carcinoma?

The general 5-year survival rate for people with SCLC is 7%. It is important to note that survival rates depend on several factors, including the stage of disease. For people with localized SCLC, which means the cancer has not spread outside of the lung, the overall 5-year survival rate is 27%.

How fast does SCLC spread?

Research has shown that SCLC has a doubling time in the range of 25–217 days. The National Cancer Institute (NCI) defines the doubling time as “the amount of time it takes for one cell to divide or for a group of cells, such as a tumor, to double in size.”

What is the leading cause of small cell carcinoma?

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.

Is small cell carcinoma hereditary?

In SCLC, genetic changes can affect oncogenes or tumor suppressor genes. These gene changes are acquired during life; they are not inherited. They are acquired because of exposure to environmental factors like smoking or they occur randomly for no known reason (spontaneously).

What is the prognosis for stage 4 small cell carcinoma?

In stage 4, the cancer has spread (metastasized) to both lungs, the area around the lungs, or distant organs. The most common type of lung cancer is non-small cell lung cancer.

What are the survival rates for stage 4 lung cancer?

Stage 5-year survival rate
Distant (stage 4) small cell lung cancer 3 percent

Can small cell carcinoma be cured?

Although small cell lung cancer is an aggressive disease, it responds well to initial chemotherapy and radiation. The goal of treatment for people with limited-stage small cell lung cancer is cure, which is achieved in 20 to 25 percent of patients.

Why is it called small cell carcinoma?

Small-cell carcinoma of the lung is also known as small-cell lung cancer (SCLC) or oat-cell cancer because the cancer cells may appear to look like oats under a microscope. Small-cell carcinoma is a type of cancer that can appear in various parts of the body, but most often occurs in the lung.

What is the difference between small cell cancer and regular cancer?

Non-small cell lung cancers include adenocarcinoma, squamous cell, and large cell carcinoma. Small cell cancers vary , depending on the expression of specific genes. Some types are more aggressive than others, but generally, small cell cancer is more aggressive than non-small cell lung cancer.

Is small cell cancer bad?

Metastasis, or cancer spread, is a top concern for people who have small cell lung cancer. Small cell lung cancer can grow quickly and affect the brain, bones and liver and adrenal glands . Small cell lung cancer that spreads is treatable but generally isn’t curable.
