Lung cancer refers to the uncontrolled growth of abnormal cells in one or both lungs. Lung cancer begins primarily in the windpipe, which manages the inflow and outflow of air to the lungs. How cancer occurs in the lung is classified by examining it under a microscope.
What are the types of lung cancer?
Lung cancer is mainly examined in 2 groups:
1. Non-small cell lung cancer (NSCLC),
2. Small cell lung cancer (SCLC),
1. Non-small cell lung cancer (NSCLC)
Non-small cell lung cancers, which make up 75% of lung cancers, generally develop and spread more slowly.
This type of lung cancer;
– Adenocancer,
– Squamous (squamous) cell cancer,
– Large cell cancer
– Mixed
Although the treatments for these types of lung cancer are similar, there are some differences, especially in terms of their targeted genomic features.
2. Small cell lung cancer (SCLC)
Small cell lung cancer, sometimes called oat cell cancer, represents 15-20% of all lung cancers. This type of lung cancer develops faster and spreads more in the body.
What are the symptoms of lung cancer?
Lung cancer begins primarily in the windpipe, which manages the inflow and outflow of air to the lungs. Although there are dozens of different types of lung cancer, more than 90% are classified into two groups as non-small cell and small cell lung cancers. Non-small cell lung cancers are classified into four groups as adeno cancer, squamous cell cancer, large cell cancer and mixed type and they constitute 75% of lung cancers. Small cell lung cancer represents 20-25% of all lung cancers.
The following findings may be caused by lung cancer or other milder diseases. For this reason, it would be a good decision to consult a doctor without wasting time and get an expert opinion.
– A persistent cough that gets worse over time
– Persistent chest pain
– Spitting blood
– Shortness of breath
– Wheezing
