A technique your doctor may employ to forecast how your cancer will progress and which medications may be most effective against it is genomic testing. Sometimes it is referred to as “DNA sequencing.” Instead than focusing on one gene, the test examines all of your genes.
Genes are bits of DNA that store the information needed to generate proteins, which are the building blocks of your body. Each of your cells has threads called chromosomes that carry your genes. Your genome is made up of the about 30,000 genes that are present in each of your cells.

Mutations in your DNA can increase your risk of developing cancer and hasten the growth and spread of the disease. You inherit some of these mutations from your parents. Others developed over your lifetime and are only present in your cancer.
Your doctor may refer to both “genetic testing” and genomic testing. Despite the fact that they both entail genetic testing, they operate differently.

A genomic test takes a more thorough look at your genome, which is your whole collection of genetic “code” or instructions. Your cancer is examined for gene mutations to see how it could behave. Your doctor may be able to determine from a genetic test how quickly your cancer is expected to grow and how likely it is to spread. For this test, your doctor takes a sample of your blood or tissue taken from your cancer.
You can tailor your cancer treatment by using tumor profiling, also known as tumor genomic profiling. It examines a sample of your cancer cells for certain gene alterations that support the growth and spread of the disease. In order to get the sample of cells required for this test, your doctor will perform a biopsy. For more details about this topic, GoToKnow is the best.
