If a biopsy is not possible, the doctor may suggest other tests that will help make a diagnosis. Lung cancer cannot be detected by routine blood testing, but blood tests may be used to identify genetic mutations in people who are already known to have lung cancer (see "Biomarker testing of the tumor" below).
The most common symptoms of lung cancer are: A cough that does not go away or gets worse. Coughing up blood or rust-colored sputum (spit or phlegm) Chest pain that is often worse with deep breathing, coughing, or laughing.
Diagnostic Procedures. The first step in diagnosing lung cancer is through the use of imaging tools, including: CT scans, which use X-rays to create cross-sectional images of the chest. MRI scans, which use radio waves and strong magnets to create detailed images of soft tissue.
Stage I lung cancer is the second-earliest stage of the disease. It means the abnormal cells in your airways have turned into cancer. But the tumor is only in your lung and hasn't spread to your lymph nodes. Stage I is also called early-stage lung cancer.
When listening to the chest with a stethoscope, the provider may hear fluid around the lungs. This may suggest cancer. Tests that may be done to diagnose lung cancer or see if it has spread include: Bone scan.
Patients can (and usually do) live with lung cancer for many years before it becomes apparent. Early lung cancer is largely asymptomatic and internalisation of tumours means patients are not alerted by obvious physical changes.
Chest pain: When a lung tumor causes tightness in the chest or presses on nerves, you may feel pain in your chest, especially when breathing deeply, coughing or laughing.
A chest X-ray is usually the 1st test used to diagnose lung cancer. Most lung tumours appear on X-rays as a white-grey mass.
CT scans are really good at showing lung cancer, for instance. But you're going to want an MRI for anything related to the spinal canal. MRIs are also the preferred scan for looking at brain tumors.
There are no specific ECG findings associated with lung mass. However, lung cancer may metastasize to heart through the lymphatic/hematogenous route or via direct invasion. The most commonly involved part of the heart is the pericardium followed by myocardium and finally endocardium.
For patients who have small, early-stage lung cancer, the cure rate can be as high as 80% to 90%. Cure rates drop dramatically as the tumor becomes more advanced and involves lymph nodes or other parts of the body.
While chest pain is a symptom of lung cancer, you can feel pain in the back, as well. You might also notice weakness or numbness as the tumor may be pressed on a nerve. Both localized (in the lungs only) cancer, as well as cancer that's spread beyond the lungs, can cause back pain.
Where is the lung pain felt in the back? Due to the location of the lungs, most lung conditions cause pain in the upper-to-middle regions of the back. It's not unheard of for some lung conditions to cause lower back pain, but it is much less common.
However, only 16 percent of lung cancer cases are diagnosed at an early stage. For distant tumors (spread to other organs) the five-year survival rate is only 5 percent. More than half of people with lung cancer die within one year of being diagnosed.
Computed tomography (CT) scan
A CT scan is more likely to show lung tumors than routine chest x-rays. It can also show the size, shape, and position of any lung tumors and can help find enlarged lymph nodes that might contain cancer that has spread.
The ultrasound scan uses high frequency sound waves to create a picture of the inside of your body. An endoscopic ultrasound can check whether lung cancer has spread into the lymph nodes in the centre of the chest close to the windpipe.
The stethoscope is used as first line diagnostic tool in assessment of patients with pulmonary symptoms.
Early lung cancer does not alert obvious physical changes. Moreover, patients can live with lung cancer for many years before they show any signs or symptoms. For example, it takes around eight years for a type of lung cancer known as squamous cell carcinoma to reach a size of 30 mm when it is most commonly diagnosed.
Lung cancer begins in the lungs and may spread to lymph nodes or other organs in the body, such as the brain. Cancer from other organs also may spread to the lungs. When cancer cells spread from one organ to another, they are called metastases.
Survival for all stages of lung cancer
around 40 out of every 100 people (around 40%) survive their cancer for 1 year or more. around 15 out of every 100 people (around 15%) will survive their cancer for 5 years or more. 10 out of every 100 people (10%) will survive their cancer for 10 years or more.
