chemotherapy help

Normally the cells of human body grow and die in a controlled way. Some times cells grow uncontrollably and form tumor inside the patients body which can cause death of the patient, the uncontrolled growth of the cells is known as cancer. Chemotherapy is the way of dealing cancer with the help of some chemicals by killing cancerous cells. The drugs used are also known as antineoplastic drugs. These drugs are also used in combination. The first modern chemotherapeutic agent was discovered by Paul Ehrlich's in 1909 that was arsphenamine, an arsenic compound. It provides systematic treatment since the drug entering through the blood stream travels throughout the body and kills cancer cells.Chemotherapeutic drugs are chemically designed to target cells that are dividing and growing rapidly. Once they reach the cancer cells, they act to retard their growth, eventually resulting in their destruction.
