The removal of telomeres from cancer cells

Since telomeres are the ends of the DNA strands, and the less there are, the shorter that strand. Is there any way that cancer cells are able to be shortened by removing the function of their telomerase?

    If you remove the telomerase the DNA can only replicate until the telomeres degrade. Then the cell looses function and initiates a process of apoptosis or an immune system removal of the dysfunctional cell.

    So, theoretically the DNA can only replicate so many times and then has to die. So in theory it might work.

    But we know that certain cell types reproduce in only days and other cell types take years to replicate. So you would still get several generations of replications before the DNA becomes dysfunctional. If the growth inhibition is not addressed, a solid tumor would continue to reproduce and possibly have areas of necrosis within it.

    But maybe if you targeted both the DNA polymerase and the telomerase you could address DNA replication. The trouble would be how to target ONLY the cancerous cells and not affect the normal DNA replication from adjacent normal cells.

    Interesting idea...
