Chemotherapy Cancer Treatment

Cancer occurs when cells begins dividing rapidly and uncontrollably, according to the National Cancer Institute. To treat this disease, drugs may be administered to kill or control the growth of cancerous cells. This treatment, known as chemotherapy, can be used alone or combined with forms of treatment.

Function

Chemotherapy uses a variety of chemicals to kill cancerous cells and slow the spread of cancer in the patient. The drugs are allowed to infiltrate the entire body to treat cancerous cells that may have spread to other areas.

Types

More than 100 drugs are used in chemotherapy, according to the American Cancer Society. These drugs may be used alone or in a variety of combinations, depending on the type of cancer being treated.

Time Frame

The time frame for chemotherapy depends on the type and stage of cancer the patient has. Chemotherapy drugs may be administered daily, weekly or monthly, and are given in cycles to allow your body to recuperate.

Side Effects

Since the chemicals target any cell that reproduces quickly, chemotherapy may affect healthy cells. This can lead to hair loss, nausea, vomiting, fatigue and loss of appetite.

Benefits

Since chemotherapy drugs are administered to the entire body, they can kill undetected cancer cells that have traveled to other parts of the body. Chemotherapy may also relieve cancer-related symptoms such as pain.
