Non Small Cell Lung Cancer Genetic Testing

Deeper understanding of the pathobiology of non small cell lung cancer nsclc has led to the development of small molecules that target genetic mutations known to play critical roles in the progression to metastatic disease.

Non small cell lung cancer genetic testing.

Some people with lung cancer have chest pain frequent coughing blood in the mucus breathing problems trouble swallowing or speaking loss of appetite and weight loss fatigue or swelling in the face or neck. Genetic testing for lung cancer involves lab tests performed on a blood or tumor tissue sample to determine if the dna of the cancer cells it contains have gene mutations or other changes that initiate the development or growth of cancer. Pennell discusses the key genetic markers for treating patients with non small cell lung cancer with targeted therapies. About 10 of people with non small cell lung cancer nsclc have a mutation in the egfr gene and.

Gene tests can also help your doctor find the right treatment for you if you do get lung cancer. Lung cancer is a disease in which certain cells in the lungs become abnormal and multiply uncontrollably to form a tumor. For example tumors in approximately 60 percent of patients. While identifying new genetic targets and developing novel drugs is important for the future of non small cell lung cancer nsclc more emphasis should be put on improving patient access to existing targeted.
