Stages of Lung Cancer
Stages of Lung Cancer
The following stages are used for non-small cell lung cancer:
Occult (hidden) stage
In the occult (hidden) stage, cancer cells are found in sputum (mucus coughed
up from the lungs), but no tumor can be found in the lung by imaging or
bronchoscopy, or the primary tumor is too small to be assessed.
Stage 0 (carcinoma in situ)
In stage 0 (carcinoma in situ), cancer is limited to the lung and is found
only in a few layers of cells. It has not grown through the top lining of the
lung.
Stage I
In stage I, the cancer is in the lung only, with normal tissue around the
tumor. Stage I is divided into stages IA and IB, based on the size of the
tumor.
Stage II
In stage II, cancer has spread to nearby lymph nodes or to the chest wall
(the ribs and muscles that make up the area of the body between the neck and
the abdomen), the diaphragm (the thin muscle below the lungs and heart that
separates the chest from the abdomen), the mediastinal pleura (the thin
membrane that covers the outside of the lungs in the area near the heart), or
the parietal pericardium (the outer layer of tissue that surrounds the
heart). Stage II is divided into stage IIA and stage IIB, based on the size
of the tumor and whether it has spread to the lymph nodes.
Stage III
In stage III, cancer has either:
spread to the lymph nodes in the mediastinum (the middle area between the
lungs that contains the heart, major blood vessels, and other structures);
or
spread to the lymph nodes on the opposite side of the chest or in the lower
neck.
Stage III is divided into stage IIIA (which is sometimes treated with
surgery) and stage IIIB (which is rarely treated with surgery).
Stage IV
In stage IV, cancer has spread to other parts of the body or to another lobe
of the lungs.

Researchers Develop Blood Test To Detect Lung Cancer
2 Aug 2006 at 4:00pm
Lung cancer is the leading cause of cancer death for both men and women in the United States and around the world, mainly because lung cancers are found in late stages and the best treatment opportunities already have been missed. In Kentucky, the incidence of lung cancer is 49 percent higher than the national rate. [click link for full article]
Modeling Lung Cancer
15 Feb 2007 at 6:00am
In a new report in the February 15th issue of G&D, Dr. Martin McMahon (UCSF) and colleagues present a novel mouse model of non-small cell lung cancer, which will serve as a useful tool to test the efficacy of novel chemotherapeutic drug therapies in the early stages of lung tumorigenesis.

Early detection of lung cancer (press release)
6 May 2005 at 11:04pm
This study was aimed at the detection of lung cancer in its early stages amongst high-risk persons by means of Computerised Axial Tomography (CAT).
Currently, 85% of cases are diagnosed at a late stage, which considerably reduces the rate of cure.
Lung cancer is the most common carcinoma in western...
Breath Test Detects Lung Cancer In Early Stages
17 Feb 2007 at 1:00am
A new breath test has been reported to detect lung cancer in its early stage. Lung cancer is the leading cause of cancer death in the United States, and doctors believe that early detection could offer sufferers their best chance for early survival. Dr. [click link for full article]

A simple blood test may be able to detect lung cancer in its earliest stages with unprecedented accuracy, according to new research to be presented at American Thoracic Society's 2008 International Conference in Toronto on Tuesday, May 20.
Study Uses Gene Test to Detect Lung Cancer Posted By : Greg Edwards
4 Mar 2007 at 11:00pm
According to a study published in the Journal of Natural Medicine, United States scientists have developed a new method to detect lung cancer in its earliest stages by locating genetic changes in a smoker's airway.
Colour sensor breath test can detect lung cancer
24 Feb 2007 at 10:00pm
A breath test can successfully pick up lung cancer with "moderate accuracy" even in the early stages, reveals research published ahead of print in Thorax. It could revolutionise the way cancer is detected and potentially save lives, say the authors.

Radiation preferred over surgery for patients with some stages of lung cancer
19 Mar 2007 at 10:00pm
After an initial chemotherapy treatment, radiation may be a better choice than surgery for patients with stage IIIA non-small-cell lung cancer, according to a randomized controlled trial published in the March 21 Journal of the National Cancer Institute. The authors suggest that a combination of chemotherapy and radiation should be the preferred treatment option for these patients.
Two New Lungs Might Be Better Than One

Researchers in France and the US have concluded that for youngerpatients in the final stages of chronic obstructive pulmonary disease(COPD), survival is lengthened by transplanting both lungs compared toonly one lung.
