The accessible anticancer drugs have discrete mechanisms of
action which may vary in their effects on various types of normal and cancer
cells. A single "cure" for cancer has proved elusive since there is
not a single type of cancer but as many as different types of cancer. In
addition, there are some demonstrable biochemical differences between cancerous
cells and Normal cells. The reason being the effectiveness of several anticancer drugs is limited by their toxicity to normal rapidly growing
cells in the intestinal and bone marrow areas.
A last problem is that
cancerous cells which are initially suppressed by a specific drug may build up
a resistance to that medication. This
is the reason why cancer chemotherapy may consist
of using various types of drugs in combination for varying lengths of time.
Chemotherapy is among the anticancer drugs. These drugs are sometimes feared because of a patient's
issue about toxic effects. Their role is to sedate and hopefully cease the
growth and lay out of a cancer.
Regrettably,
bulks of drugs currently on the market are not specific, which leads to the
diverse ordinary side effects associated with cancer chemotherapy. Because the
typical approach of all chemotherapy is to lessen the growth rate of the cancer cells, the side effects are seen in physical
structures that naturally have a rapid turnover of cells including skin, digestive, hair and bone marrow. These
strong, healthy and normal cells also end up damaged by the
chemotherapy program.
