Cancer treatments are possible by chemo drugs,their role is to slow and hopefully
decrease the growth and expansion of a cancer. There are three goals associated
with the use of the mostly used anticancer agents for example,destroy the DNA
of the affected cancer cells,Inhibit the synthesis of fresh DNA strands to
cease the cell from replicating, because this is what allows the tumor to
expand and the actual breaking apart of the original cell into further fresh
cells.
Stopping mitosis ceases cell splitting of the cancer and may
ultimately slow down the procedure of the cancer. Unfortunately, most of the chemo
drugs currently available are not specific,
which leads to common side effects associated with chemotherapy. Because the
common approach of chemotherapy is to lessen the growth rate of the cells, the
side effects are seen in bodily systems that naturally have a quick turnover of
cells including skin, hair etc. Thesecells also get damaged by the chemotherapy
program.
Chemotherapy agents can be grouped into three
categories based on their function for example, Stop the synthesis of pre DNA molecule building blocks;these
agents toil in many different ways,directly
harm the DNA in the nucleus of the cell; these agents chemically ruin
DNA and RNA and they disrupt replication of the DNA and either totally terminate
replication, breakdown of the mitotic
spindles;these drugs disrupt the production of these spindles and
therefore interrupt cell division.
