What Is Cancer? - NCI - National Cancer Institute
2021年10月11日 · Explanations about what cancer is, how cancer cells differ from normal cells, and genetic changes that cause cancer to grow and spread.
Understanding Cancer - NCI
At its most basic, cancer is a disease of the genes in the cells of our body. Genes control the way our cells work. But, changes to these genes can cause cells to malfunction, causing them to grow and divide when they should not—or preventing them from dying when they should.
Research Areas: Cancer Biology - NCI - National Cancer Institute
2024年8月14日 · Research on the biology of cancer starts with the simplest of questions: What is—and isn’t—normal? To understand how cancer develops and progresses, researchers first need to investigate the biological differences between normal cells and cancer cells.
Mechanisms of Cancer | Center for Cancer Research
Understanding the fundamentals of how cancer cells form and proliferate has been crucial to cancer treatment and prevention. New areas of basic research will lead to better outcomes for patients.
The Genetics of Cancer - NCI - National Cancer Institute
2024年8月8日 · Two cancer cells in the same tumor can have different DNA changes. In addition, every person with cancer has a unique combination of DNA changes in their cancer. For more information on the biological changes that make cells cancerous, see What is Cancer?
Cell Metabolism and Cancer | Center for Cancer Research
The metabolism of cancer cells differs markedly from that of healthy cells, and it is now becoming clear that these differences may be a driving force of cancer cells. This insight will lead to new approaches to disrupt cancer cells’ metabolic pathways.
Signals released from dying cancer cells accelerate metastatic …
2023年3月27日 · The team has identified the molecular pathway that cancer cells use to detect and respond to the signals released by dying cells. They say it may be possible to block those signals to prevent cells that die during cancer therapy from provoking the growth of any cancer cells that remain.
Metastatic Cancer: When Cancer Spreads - NCI - National Cancer …
2020年11月10日 · Cancer that spreads from where it started to a distant part of the body is called metastatic cancer. For many types of cancer, it is also called stage IV (4) cancer. The process by which cancer cells spread to other parts of the body is called metastasis.
Cryosurgery to Treat Cancer - NCI - National Cancer Institute
2021年6月21日 · Cryosurgery is a local treatment that uses extreme cold produced by liquid nitrogen or argon gas to destroy cancer cells and abnormal tissue. Learn how cryosurgery works, about the types of cancer and precancers it is used to …
Chemotherapy to Treat Cancer - NCI - National Cancer Institute
Chemotherapy is a type of cancer treatment that uses drugs to kill cancer cells. Learn how chemotherapy works against cancer, why it causes side effects, and how it is used with other cancer treatments.
