Lung cancer is one of the common cancers in India. Smoking, chewing tobacco, increasing environmental pollution and other harmful carcinogenic compounds
such as asbestos, arsenic, are a few things that triggerÃÂ lung cancer.
Tests to diagnose lung cancer
If there's reason to think that you may have lung cancer, your doctor can order a number of tests to look for cancerous cells and to rule out
other conditions. In order to diagnose lung cancer, your doctor may recommend:
Chest X Ray
An X-ray image of your lungs may reveal an abnormal mass or nodule. To know more Click Here
Computed tomography (CT) scan
A CT scan can reveal small lesions in your lungs that might not be detected on an X-ray. A CT scan can
also provide precise information about the size, shape, and position of any lung tumours and can help
find enlarged lymph nodes that might contain cancer that has spread from the lung. To know more Click Here
For this test, a sample of sputum (mucus you cough up from the lungs) is looked at under a microscope
to see if it contains cancer cells. The best way to do this is to get early morning samples from you 3
days in a row. To know more Click Here
Tissue sample (biopsy)
Your doctor can perform a biopsy in a number of ways including, Bronchoscopy,Mediastinoscopy,Needle
biopsy. To know more Click Here
Detailed genetic testing can be done on your tumor to help you and your doctor decide on the right treatment option for you.
These tests may involve:
- looking for changes (mutations) in the DNA make-up of the tumor
- looking at levels of specific proteins present in the tumor
These characteristics are usually present in your tumor only, not in other tissues in your body. Knowing your tumour characteristics is important
for doctor to plan personalised or targeted therapies which specifically attack cancer cells without harming normal tissues and have minimal
Epidermal Growth Factor Receptor (EGFR) mutation testing
EGFR mutation testing is the analysis of tumour DNA to detect mutations in the EGFR gene.
In normal cell growth, small chemicals called growth factors are produced by one cell and attach to proteins called receptors on that same or
nearby cells. By attaching to these receptors, the growth factors start a chemical reaction inside the cell, which causes the cell to grow and
multiply. In cancer, there may be too many growth factors present, or the receptor may be mutated so that it Ã¢ÂÂthinksÃ¢ÂÂ the growth factor is
attached when it really isnÃ¢ÂÂt. One such receptor that can be mutated in lung cancer is the Epidermal Growth Factor Receptor (EGFR). To know more
KRAS mutation testing
KRAS Mutation testing is the analysis of tumour DNA to detect mutations in the KRAS gene. KRAS is homologous to the oncogene from the
Kirsten rat sarcoma virus. RAS proteins act as a switch that controls cell proliferation. Oncogenic mutation makes RAS insensitive so it is
continually switched Ã¢ÂÂon.Ã¢ÂÂ The message is delivered continuously, giving the cell unchecked permission to proliferate.To know more Click Here
Anaplastic Lymphoma Kinase (ALK) mutation testing
ALK Mutation testing is the analysis of tumour DNA to detect mutations in the ALK gene.
ALK is another growth factor receptor that can be present
in cancer cells. ALK appears to be essential during fetal development, and is normally present in adults only in brain tissue. However, in some cancer
cells type of mutation called a gene rearrangement occurs that fuses another gene to ALK and Ã¢ÂÂturns it on,Ã¢ÂÂ telling cancer cells to multiply.
