What Is Cancer? - NCI - National Cancer Institute
2021年10月11日 · Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes.
Cell Biology of Cancer - SEER Training
A cancer cell is a cell that grows out of control. Unlike normal cells, cancer cells ignore signals to stop dividing, to specialize, or to die and be shed. Growing in an uncontrollable manner and unable to recognize its own natural boundary, the cancer cells may spread to areas of the body where they do not belong.
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.
