How fast do cancer cells divide (compared to normal cells)?

WebDoctors call this superficial cancer growth or carcinoma in situ (CIS). The cancer cells grow and divide to create more cells and will eventually form a tumour. A tumour may contain millions of cancer cells. All body tissues have a layer (a membrane) that keeps the cells of that tissue inside. This is the basement membrane. WebTelomerase is not usually active in most somatic cells (cells of the body), but it’s active in germ cells (the cells that make sperm and eggs) and some adult stem cells. These are cell types that need to undergo many divisions, or, in the case of germ cells, give rise to a new organism with its telomeric “clock” reset 5 ^5 5 start superscript, 5, end superscript .
