Can you survive small cell lung cancer?
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 do lung cancer cells become cancer cells?
A normal lung cell becomes a cancer cell after a series of mutations in genes that control cell growth (often both oncogenes and tumor suppressor genes) results in a cell that behaves very differently than a normal cell. These mutations do not usually all happen at once, but accumulate over a significant period of time, sometimes decades. On average, a typical cancer cell must divide roughly 30 times before a tumor is 1 centimeter in diameter (roughly half an inch). At this point, the cell has multiplied to become 10 billion to 100 billion cells, and is just barely detectable (if at all) on a chest X-ray.

Can doubling times be used to predict tumor growth?
Looking at doubling times of tumors is helpful only if estimated doubling times can be used to predict the growth of a person's tumor. One study looked at predicted survival times of people who had inoperable lung cancers (before recent advances in targeted therapies and immunotherapy) and found that there was a close correlation between survival predicted from doubling time and actual survival. 5
How many times do cancer cells divide?
On average, a typical cancer cell must divide roughly 30 times before a tumor is 1 centimeter in diameter (roughly half an inch).
Does lung cancer spread quickly?
The answer is that it may depend, and how quickly a lung cancer spreads may be tied closely with the type of lung cancer. While there are differences, it's important to note that any lung cancer (other than stage 0 lung cancer or carcinoma in situ) has the potential to spread.
How do tumors change?
As a cancer grows, the cells develop further mutations that can change the behavior of a tumor. Many people are familiar with this phenomenon as it is often the new mutations in a tumor that make it resistant to a treatment that had previously worked. Some of the added mutations in a tumor may result in the cancer cells growing and dividing more rapidly than when it first developed.
Can lung cancer spread to the brain?
Any stage or size lung cancer has the potential to spread. Overall, small cell lung cancer has the potential to spread very early. Even very tiny small cell lung cancers may spread, for example, to the brain, and symptoms related to brain metastases are not uncommonly the first symptoms of the disease.

Can a person prevent SCLC?
Understanding the risk factors for SCLC may help some people prevent the condition or minimize its growth.
Can a person slow the spread of SCLC?
The NCI states that most cases of SCLC are not curable. However, it may sometimes be possible to slow the growth of SCLC.
Outlook
The outlook for people with SCLC is generally less positive#N#Trusted Source#N#than it is for those with other types of lung cancer. The reason for this is that when the majority of people with SCLC begin to show symptoms of the disease, the cancer will already have metastasized.

Where does lung cancer spread?
While it’s possible for lung cancer to spread virtually anywhere, it most commonly metastasizes in the liver, brain, bones or adrenal glands.
Can lung cancer be treated with radiation?
When lung cancer spreads locally, to nearby tissues such as the lining of the lung or lymph nodes, surgery could be an effective option, whereas radiation therapy or chemotherapy might be more likely to be recommended for lung cancer that has spread to distant parts of the body.
Why does cancer happen?
Cancer occurs when there are more abnormal cells than the immune system can handle. Instead of dying, abnormal cells continue to grow and divide, piling up in the form of tumors.
What is it called when cancer spreads to another body?
The spread of cancer from where it started to another place is called metastasis. No matter where else in the body it spreads, a cancer is still named for the place it originated. For instance, prostate cancer that has spread to the liver is still prostate cancer, not liver cancer, and treatment will reflect that.
How many types of cancer are there?
There are more than 100 types of cancer named for the tissues or organs where they originate. All have the ability to spread, but some are more aggressive than others. Continue reading to learn how cancer spreads, how it’s staged, and how various treatments work.
Is leukemia a solid tumor?
While solid tumors are a feature of many types of cancer, that’s not always the case. For example, leukemias are cancers of the blood that doctors refer to as “liquid tumors.”. Exactly where cancer cells will spread next is dependent on their location in the body, but it’s likely to spread nearby first.
Why is chemotherapy used for cancer?
Chemotherapy is used to kill cancer, slow its growth, and reduce the chance that new tumors will form. It’s useful when cancer has spread beyond the primary tumor or if you have a type of cancer for which there are no targeted therapies.
What is the grade of a tumor?
Based on how abnormal they appear under a microscope, tumors are graded as follows: GX: undetermined. G1: well-differentiated or low-grade.
How does cancer spread?
Cancer can spread through: Tissue. A growing tumor can push through surrounding tissues or into organs. Cancer cells from the primary tumor can break away and form new tumors nearby. The lymph system. Cancer cells from the tumor can enter nearby lymph nodes.
What is the life expectancy of lung cancer?

Prognosis
Treatment
- There are four goals of any medical treatment: preventative, curative, management and palliative. Perhaps you are past the curative stage, but palliative, meaning relieving pain, might be a consideration for you. A doctor will help you navigate through the different treatment options that fit your needs and that can give you the best quality of life. Unfortunately, many people do not re…
Quotes
- \"They told me that the survival rate for my cancer was only 5 percent and I said wonderful! That means that there are five out of 100 people who make it with this disease, and I'm going to be one of those five!\"A 10-year survivor of advanced-stage lung cancer
Diagnosis
- Understanding cancer can be difficult. Sometimes there is miscommunication. A doctor may help clear up something about lung cancer, survival rates, or treatment plans.
Controversies
- Some people may choose to pass on treatment due to religious beliefs that forbid cancer treatment. This is a very personal issue for those with cancer to weigh based on their convictions.
Causes
- Some people pass on treatment because of the stigma of lung cancer. Smoker's guilt may get the best of you and you might think that you deserve it. Nobody deserves cancer. Not only does lung cancer occur in smokers and non-smokers alike, but it does not matter because everyone deserves compassion, care, and the best medical treatments available.
