Answer 1

Answer:

Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cells in your body.Chemotherapy is most often used to treat cancer, since cancer cells grow and multiply much more quickly than most cells in the body.

Answer 2

Answer:

Chemotherapy, or "chemical treatment," has been around since the days of the ancient Greeks. However, chemotherapy for the treatment of cancer began in the 1940s with the use of nitrogen mustard. Since then, in the attempt to discover what is effective in chemotherapy, many new drugs have been developed and tried.

Sometimes referred to simply as "chemo", chemotherapy is used most often to describe drugs that kill cancer cells directly. These are sometimes referred to as "anti-cancer" drugs or "antineoplastics." Other chemo drugs such as biologic response modifiers, hormone therapy, and monoclonal antibodies, which work in different ways to treat cancer, are included in this web-site. Today's therapy uses more than 100 drugs to treat cancer. There are even more chemo drugs still under development and investigation.

Explanation:

Since cancer is a word used to describe many different diseases, there is no one type of treatment that is used universally. Chemotherapy is used for a variety of purposes:  

To cure a specific cancer;

To control tumor growth when cure is not possible;

To shrink tumors before surgery or radiation therapy;

To relieve symptoms (such as pain); and

To destroy microscopic cancer cells that may be present after the known tumor is removed by surgery (called adjuvant therapy). Adjuvant therapy is given to prevent a possible cancer reoccurrence.
