Cancer cells from your body were examined to see how active certain genes are.

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

Somatic cells and therefore also cancer cells usually hold a complete blueprint of your body. This blueprint consists of genetic information. Individual sections of genetic information are called genes. Genes contain instructions according to which a cell produces certain proteins. These proteins control many processes in the cell, for example, growth. A gene can be active to varying degrees. The activity of a gene determines how much of a particular protein the cell produces. This investigation involved removing cancer cells and then examining them in a laboratory using special methods.
