A second group of genes implicated in cancer are the "tumor suppressor genes." Tumor suppressor genes are normal genes whose ABSENCE can lead to cancer.
They resemble proto-oncogenes in that they code for the production of proteins involved in growth control. However, oncogenes code for an altered version (or excessive quantities) of these growth-control proteins, thereby disrupting a cell's growth-signaling pathway.
Lung Cancer - National Cancer Institute Lung Cancer - National Cancer Institute The lungs are a pair of cone-shaped breathing organs inside the chest. The lungs bring oxygen into the body when breathing in and send carbon dioxide out of the body when breathing out.
This knowledge has improved our understanding of the biology of cancer and led to new methods of diagnosing and treating the disease. Over the past decade, large-scale research projects have begun to survey and catalog the genomic changes associated with a number of types of cancer.
