How Chemotherapy Helps in Controlling Cancer, the Threat To Mankind
Chemotherapy is a treatment used to prevent the growth of the cancer cells. Chemotherapy which is sometimes referred to as chemo' is a systemic therapy in which the whole body is affected as the medicine is going through the bloodstream. In this treatment medicines are used which weaken and destroy the growth of the cancerous cells. Chemotherapy destroys the cells at the actual cancer site and also the cancer cells which has spread to the other parts of the body. Chemotherapy treatment either destroys the cells or stops them from growing. In some cases of breast cancer, this treatment is used before surgery to shrink the cancer.
Cancer cells have a tendency to grow and divide very quickly in an uncontrolled manner and Chemotherapy treatment is used to put a check on this growth. As these cells are fast in growing, at times they break away from the actual tumor and move to the other parts of the body. The normal cells of the body grow and divide in a controlled and in orderly manner. Some normal cells of our body grow faster such as nails, bone marrow which makes the blood and the hair follicles. By using Chemotherapy, these cells might get harmed unintentionally and certain symptoms might be visible, which are the side effects of Chemotherapy.
Patients can undergo Chemotherapy treatment at home, in a clinic or in a hospital. Depending on the type or stage of the cancer, type of drug or the response of the body towards the Chemotherapy treatment, the frequency of the treatment is fixed. The dosage of the Chemotherapy drugs depends on the weight of the patient's body and the toxicity of the drugs used. The frequency of the Chemotherapy treatment could be daily, weekly or monthly.
