It refers to the treatment of human disease using chemical substances.
Human chemotherapy is a medical treatment method designed to combat and control the growth of cancerous cells within the human body. It involves the administration of powerful medications, known as chemotherapeutic agents or cytotoxic drugs, which target and destroy cancer cells. Chemotherapy can be used as the primary treatment to eliminate cancerous cells, as an adjuvant therapy following surgery to eradicate residual cells, or as a palliative treatment to reduce symptoms and manage the progression of advanced cancer.
Chemotherapeutic agents work by interfering with the cancer cells' ability to grow and divide, ultimately leading to their destruction. These drugs may be administered orally or intravenously, and they travel throughout the bloodstream to reach cancer cells wherever they may be in the body. While chemotherapy primarily targets rapidly dividing cells, such as cancer cells, it can also affect normal, healthy cells that naturally have a high rate of division, such as those in the bone marrow, gastrointestinal tract, and hair follicles. This may cause side effects such as weakened immune system function, hair loss, nausea, and fatigue.
Human chemotherapy is often used in conjunction with other cancer treatments, such as surgery, radiation therapy, or immunotherapy, to provide a comprehensive approach to cancer care. The specific combination and duration of chemotherapy treatment depend on the type and stage of cancer, as well as individual patient factors. The goal of human chemotherapy is to achieve remission or prolonged survival, improve quality of life, and potentially cure the cancer, if possible.
The word "chemotherapy" originated from the combination of two Greek words: "chemy" (meaning "chemical") and "therapeia" (meaning "treatment"). It was initially used in the late 19th century to describe the treatment of diseases using chemical substances. The addition of the word "human" simply specifies that the chemotherapy treatment being referred to is meant for humans as opposed to animals or other organisms.
