Cancer is a class of diseases characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue (invasion) or by implantation into distant sites (metastasis)
How does cancer affect the rate of mitosis and the normal cell life cycle? please i need help its for biology……
Cancer results from cells that, for whatever reason, have a greater proliferation and/or longer lifespan than a regular cell! They do not follow the normal rules of cell proliferation and death! Cancer cells affect the cells around them by releasing signals and chemicals (cytokines) that can affect their growth or kill them! Different types of cancers affect different types of cells in a variety of ways! For instance, cancers that cause inflammation can lead to tissue fibrosis (scarring) or apoptosis of nearby cells! Cancers can cut of blood supply to cells(sarcomas) or create to many blood vessels(angiomas)! Cancers that spread are cancerous cells that have migrated either by moving/ proliferation or traveled through the blood stream to incorporate themselves to a tissue they dont belong in! Once there they either impede in normal organ or tissue function or cut off blood and nutrient supplies!
How can cancer affect normal cell functioning? Cancer makes cells divide in an uncontrollable way which can group into tumors. Cancer cells how they differ
