Symptoms of Lung Cancer Stages
Symptoms of Lung Cancer Stages There are two main types of lung cancer: The small and the non-small cell. Everyone is staged differently. Knowing the stage will help your doctor choose the right treatments for you. It can also help her measure your chances of success with this treatment. One thing your lung cancer phase can’t tell you is how long you’ll live.
What is the TNM system?
Staging of lung cancer often uses the letters T, N, and M:
- T stands for the size of your tumor and where it is located in the lungs or body.
- N stands for node participation. That means whether or not your cancer has spread to the lymph nodes near the lungs.
- M stands for metastasis. That means whether your cancer has spread or not. Lung cancer can spread to the other lungs or liver, bones, brain, kidneys, adrenal glands or other parts of the body.
Your doctor can stage your tumor with these letters, and then be more specific with the numbers 0-4.
It measures the size of your tumour in centimetres to give it a number. The larger the number, the more the volume has grown or spread. She could also use X as a number. This means the tumour cannot be measured or is unclear how far it has spread.

Small cell lung cancer levels
If you have this type of cancer, your doctor can use the TNM system. Then she’ll put your cancer in one of those two main stages:
- Limited level. It is located in just one lung and possibly near lymph nodes. It hasn’t spread to both lungs or past the lungs.
- Extensive stage. Her tumor has spread to other areas of the lungs and chest. It may have spread to the fluid around the lungs (called the pleura) or other organs such as your brain.
Non-Small cell Lung Cancer Stages
Non-small cell lung cancer (NSCLC) is a more common type of lung cancer than small cells.
One way to describe NSCLC is through the clinical or pathological phase. Your doctor could use imaging scans to see what clinical stage it is at. You let them photograph the inside of your body. She could also do a biopsy where she takes a small piece of tissue from the tumour and looks at it under a microscope.
If you have cancer surgery, your doctor can look at your tumor and see the pathological stage of your cancer. That tells your doctor how far the cancer has grown or spread. The most common way to stage your NSCLC tumor is to use the TNM system with the numbers X, 0, 1, 2, 3 or 4 after each letter.
Number and letter combinations describe:
- The width of your tumour is measured in centimetres, or if it is too small to even be measured
- Where your tumor is in your lungs
- If there is more than one tumor in the same lung
- If your airways are partially blocked or clogged enough to cause a lung collapse or pneumonia
- If the tumor has spread to your lymph nodes or other organs
Doctors can also use general levels for NSCLC. You can use the TNM system and the numbers to organize your cancer in each of them:
- Exclusive phase: Cancer cells can be taken in the mucus you cough. Its volume is not observed in imaging assays or biopsy. It is also called hidden cancer.
- Stage 0: Your tumor is very small. Cancer cells have not spread to your deeper lung tissue or outside your lungs.
- Stage I: Cancer is in your lung tissue, but not in your lymph nodes.
- Stage II: The disease may have spread to the lymph nodes near the lungs.
- Stage III: It has spread further into the lymph nodes and into the middle of the chest.
- Stage IV: Cancer has spread far around the body. It may have spread to the brain, bone or liver.

Symptoms of Lung Cancer Stages
Lung cancers can often be mistaken for bronchitis or pneumonia. That’s one reason more than 70 percent of lung cancers are already in advanced stages when found.
The earlier lung cancer is detected, the better the chances that it will be successfully treated. The ACS says a doctor should be consulted if someone:
- Has a persistent cough, or cough blood or dark-colored phlegm
- Has a hoarse voice, chest pain, shortness of breath, or is blowing
- Often has respiratory infections
- Feels or weak, or has lost her appetite and loses weight
As lung cancer progresses, new symptoms may appear. Some of them:
- Headache, dizziness or seizures, due to the spread of cancer to the nervous system
- Jaundice, due to cancer spreading to the liver
- Lumps under the skin, due to the spread of cancer in the lymph nodes
- Back pain, hip pain or general bone pain
Even without these Symptoms of Lung Cancer Stages, a preventative lung cancer examination may be recommended. Although no significant benefit has been demonstrated for low-risk patients, there is strong evidence that screening in heavy smokers can significantly reduce mortality. A 2011 study in the New England Journal of Medicine found 20 percent fewer deaths in heavy smokers who underwent annual CT scans compared to a group of heavy smokers not tested.
