Chemotherapy :
Chemotherapy is a type of treatment that employs anticancer drugs to target cancer cells and eventually lead them to death. It uses the administration of highly potent drugs that would either kill the cancer cells directly or inhibit them from dividing and multiplying. Chemotherapy is usually applied for all cancers including breast, lung, colorectal, among others and alone in use or in combination with surgery and radiation therapy. An injection will be administered to the patient through an oral and intravenous mode, depending on the type of cancer and the treatment plan. This is, however, its principal aim of shrinking the sizes of tumors and preventing the spread of cancerous cells hence squashing all the remaining cancerous cells after surgery. Since chemotherapy does not differentiate and affects nearly all the dividing cells, including hair follicles and bone marrow side effects result in a vast number of symptoms including nausea, fatigue, hair loss, and risk for infections. Chemotherapy is given in cycles allowing the body to rest and recover for a period. Chemo sometimes is also prescribed according to an individual's type of cancer and stage of cancer, which further enhances the chances of survival and reduces the chances of recurrence.
