Lung cancer is one of the most common and serious types of cancer. Around 47,000 people are diagnosed with the condition every year in the UK. There are usually no signs or symptoms in the early stages of lung cancer, but many people with the condition eventually develop symptoms including: You should see a GP if you have these symptoms. Cancer that begins in the lungs is called primary lung cancer. Cancer that spreads to the lungs from another place
in the body is known as secondary lung cancer. This page is about primary lung cancer. There are two main forms of primary lung cancer. These are classified by the type of cells in which the cancer starts growing. They are: The type of lung cancer you have determines which treatments are recommended. Lung cancer mainly affects older people. It's rare in people younger than 40. More than 4 out of 10 people diagnosed with lung cancer in
the UK are aged 75 and older. Although people who have never smoked can develop lung cancer, smoking is the most common cause (accounting for about 72% of cases). This is because smoking involves regularly inhaling a number of different toxic substances. Treatment depends on the type of mutation the cancer has, how far it's spread and how good your general health is. If the condition is diagnosed early and the cancerous cells are confined to a small area, surgery to remove the affected area of lung may be recommended. If surgery is unsuitable due to your general health, radiotherapy to destroy the cancerous cells may be recommended instead. If the cancer has spread too far for surgery or radiotherapy to be effective, chemotherapy is usually used. There are also a number of medicines known as targeted therapies. They target a specific change in or around the cancer cells that is helping them to grow. Targeted therapies cannot cure lung cancer but they can slow its spread. OutlookLung cancer does not usually cause noticeable symptoms until it's spread through the lungs or into other parts of the body. This means the outlook for the condition is not as good as many other types of cancer. About 1 in 3 people with the condition live for at least 1 year after they're diagnosed and about 1 in 20 people live at least 10 years. However, survival rates vary widely, depending on how far the cancer has spread at the time of diagnosis. Early diagnosis can make a big difference. Page last reviewed: 15 August 2019 Stage 4 lung cancer means that your cancer has spread from your lung to other parts of your body. Once the cancer spreads it’s hard to cure. Chemotherapy and other treatments can slow your disease and help you live longer, but they probably won’t cure you. You might have months or years to live after a stage 4 lung cancer diagnosis. Or, you could have only weeks. Your doctor will tell you what to expect based on the results of your tests. At some point, your doctor might tell you that you’ve reached the final stages of lung cancer. Treatment will no longer help you at this point. The goal at this stage is to ease your pain and other symptoms to help keep you comfortable. You’ll also need emotional support. It can be challenging to learn you have stage 4 lung cancer, but your healthcare team and other medical professionals can help you and your family members cope. Whether it’s you or a loved one who is facing the final stages of lung cancer, knowing what to expect can help you navigate the process and get the support you need. Each person’s experience at the end of life is unique. The process may be very slow and gradual, or quick. These symptoms are common in people who have reached the final stages of lung cancer:
Having one or more of these symptoms doesn’t mean that you or your loved one is close to death, but they can be signs. Your doctor or hospice staff can offer you treatments to relieve these symptoms and make you more comfortable. Not all symptoms in the final stages of lung cancer are physical. It’s also normal to feel anxious or depressed at this stage. Ask for support from a therapist or other mental health provider. If you’re spiritual, you may also want guidance from a member of your religious organization. Cancer happens when cells multiply much faster than normal. Those extra cells form tumors and may spread to other parts of the body, which can damage organs or prevent them from working. Cancer can damage your lungs to the point where they can’t send out enough oxygen to meet your body’s needs. Or a large tumor can block your lungs and make it hard for you to breathe. Sometimes the bacteria that cause infections like pneumonia grow when there is a blockage in your lungs. Your body may be too weak from the cancer to fight off the infection. A tumor can also block a blood vessel. This blockage can slow or stop the flow of blood to your lungs and other parts of your body. Lung cancer also spreads to vital organs like the liver. Damage to the liver can prevent it from doing its job of removing toxins from your blood, helping your body store energy, and producing cholesterol and proteins. Cancer that spreads to your brain is also life threatening. Your brain controls all of your vital functions, including breathing. According to the American Cancer Society, people with stage 4 lung cancer are about 6 percent as likely to live for 5 years as someone who doesn’t have this cancer. However, lung cancer takes a different course in each person. People can live for weeks, months, or sometimes even years after they’re diagnosed. How long you might live depends on factors like your age, your overall health, and where the cancer is in your body. Lung cancer treatments such as chemotherapy and immunotherapy can extend the lives of people with stage 4 lung cancer. Yet not everyone is able to receive treatment or wants treatment. How long you’ll live without treatment is hard to predict. Research finds that people with non-small cell lung cancer live for an average of 7 months if they don’t receive treatment. However, some people live longer or shorter than 7 months. Your doctor can give you an idea of your prognosis with stage 4 lung cancer. Looking at your symptoms and how far your cancer has spread will help predict how long you might live. Once you’re in the final stages of lung cancer and treatment is no longer effective, you can qualify for hospice care. Hospice focuses on relieving your symptoms and supporting you through the rest of your cancer journey. You can receive hospice in your home or at a hospice center. Whether it’s you or a loved one who is facing the final stages of lung cancer, it can be a very emotional time. Make sure you have all the support you need from your friends and family, doctors, and other members of your healthcare team. How fast does lung cancer spread without treatment?A 2018 study found that the median doubling time varies by type of NSCLC: Adenocarcinomas had a median doubling time of 261 days. Squamous cell carcinomas had a median doubling time of 70 days. Other lung cancers, which included large cell carcinomas and SCLC, also had a median doubling time of 70 days.
What are the signs of end stage lung cancer?What are the signs of end-of-life lung cancer?. Persistent cough and shortness of breath.. Fluid build-up around lungs.. Severe fatigue.. Loss of appetite and nausea.. What is life expectancy for inoperable lung cancer?Life Expectancy for Inoperable Lung Cancer
This 5-year survival rate is 24% overall for non-small-cell lung cancer and 6% overall for small-cell lung cancer. Five-year survival rates for people who have NSCLC are: 61% if the cancer hasn't spread outside the lung. 35% if it's spread to nearby areas.
How long can you live with untreated Stage 4 lung cancer?Summary. Stage 4 NSCLC is an advanced form of lung cancer in which cancer has spread from the lungs to distant organs or areas of the body. The median survival time for stage 4 lung cancer is about four months.
