Lung cancer biomarkers are pieces of DNA, proteins, or hormones that cancer cells secrete or your body secretes in response to cancer. In the I Wear Black for Melanoma Cancer Awareness Shirt for Women Men Teen Kids Tee limited Shirt past, everyone with lung cancer were treated equally. Currently, there are targeted therapies based on biomarkers. More than 1 in 4 people with adenocarcinoma, a type of non-small cell lung cancer (NSCLC), has biomarkers with targeted treatment.

Your doctor may also use biomarkers to diagnose your cancer and find out how fast it could grow. Biomarkers help to predict which treatments are likely to work best for your cancer. Biologic markers can also show how well your treatments are working. It leads to the production of a protein that causes cancer cells to overgrow. Between 10 and 15 percent of lung cancer cases test positive for EGFR.

This gene encodes the I Wear Black for Melanoma Cancer Awareness Shirt for Women Men Teen Kids Tee limited Shirt MET protein, which sends a signal to grow to cancer. A mistake called skipping exon 14 prevents the MET protein from being broken down, resulting in your body has more protein. About 5% of people with lung cancer with MET 14 ignore it. This gene mutation sends signals to promote cancer growth. Similar gene mutations have been linked to breast and ovarian cancers. Approximately 3% of lung cancers test positive for HER2.

The biomarker test finds the DNA and protein changes that are specific to your tumor. Your doctor will get a report showing which biomarkers are in your cancer or blood. Biological imprints can help show your doctor the most likely effective targeted treatments or immunotherapy for your cancer. Biomarker research was carried out in the early 2000s with the approval of the first drugs to target EGFR-positive lung cancer. Since then, researchers have discovered more than 20 different driver mutations that contribute to lung cancer development.

The I Wear Black for Melanoma Cancer Awareness Shirt for Women Men Teen Kids Tee limited Shirt search is underway to look for more biomarkers, which will hopefully lead to new targeted lung cancer treatments. The FDA has approved more than 20 targeted therapies for people with specific lung cancer biomarkers. Biomarkers have improved lung cancer diagnosis and treatment. These genetic changes have resulted in new and more precise treatments. If you are diagnosed with lung cancer, ask your doctor if you should have a biomarker or molecular test.
