Can cancer cells ever truly die?!


Question: Can cancer cells ever truly die?
Besides from the host being dead of course

Answers:

Universal Trigger,
Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Apoptosis, or programmed cell death, is a normal component of the development and health of multicellular organisms. Cells die in response to a variety of stimuli and during apoptosis they do so in a controlled, regulated fashion. This makes apoptosis distinct from another form of cell death called necrosis in which uncontrolled cell death leads to lysis of cells, inflammatory responses and, potentially, to serious health problems. Apoptosis, by contrast, is a process in which cells play an active role in their own death (which is why apoptosis is often referred to as cell suicide). Some viruses associated with cancers use tricks to prevent apoptosis of the cells they have transformed. Even cancer cells produced without the participation of viruses may have tricks to avoid apoptosis. Some B-cell leukemias and lymphomas express high levels of Bcl-2, thus blocking apoptotic signals they may receive. The high levels result from a translocation of the BCL-2 gene into an enhancer region for antibody production. [Discussion]. Melanoma (the most dangerous type of skin cancer) cells avoid apoptosis by inhibiting the expression of the gene encoding Apaf-1. Some cancer cells, especially lung and colon cancer cells, secrete elevated levels of a soluble "decoy" molecule that binds to FasL, plugging it up so it cannot bind Fas. Thus, cytotoxic T cells (CTL) cannot kill the cancer cells by the mechanism shown above. Other cancer cells express high levels of FasL, and can kill any cytotoxic T cells (CTL) that try to kill them because CTL also express Fas (but are protected from their own FasL).



Yeah, all cells are vulnerable while they are multiplying. Cancer cells multiply much faster than ordinary cells, which ironically makes them much easier to kill than normal cells. This is how a lot of cancer treatments work. The problem is that it is hard to kill ALL the cells, if some are left, it can come back.



All people are born with cancer cells, they just become "cancerous" for some people.

All cells have a "life cycle"
So yes, they do die.



i think so.
