| Chemotherapy : is the use of chemical substances to treat disease Chemotherapy is the treatment of cancer with drugs that can destroy cancer cells. These drugs often are called "anticancer" drugs.
How Does Chemotherapy Work Normal cells grow and die in a controlled way. When cancer occurs, cells in the body that are not normal keep dividing and forming more cells without control. Anticancer drugs destroy cancer cells by stopping them from growing or multiplying. Healthy cells can also be harmed, especially those that divide quickly. Harm to healthy cells is what causes side effects. These cells usually repair themselves after chemotherapy Because some drugs work better together than alone, two or more drugs are often given at the same time. This is called combination chemotherapy What Can Chemotherapy Do 1- To control the cancer. This is done by keeping the cancer from spreading; slowing the cancer's growth; and killing cancer cells that may have spread to other parts of the body from the original tumor. 2- To relieve symptoms that the cancer may cause. Relieving symptoms such as pain can help patients live more comfortably.
Causes Side Effects The fast-growing, normal cells most likely to be affected are blood cells forming in the bone marrow and cells in the digestive tract (mouth, stomach, intestines, esophagus), How Long Do Side Effects Last Normal cells usually recover when chemotherapy is over, so most side effects gradually go away after treatment ends, and the healthy cells have a chance to grow normally. The time it takes to get over side effects depends on many things, including your overall health and the kind of chemotherapy you have been taking. Fatigue << Fatigue from cancer feels different from fatigue of everyday life Nausea and Vomiting < vomiting while receiving chemotherapy What can I do if I have nausea and vomiting Drink liquids at least an hour before or after mealtime . Drink frequently and drink small amounts . Eat and drink slowly . Eat small meals throughout the day . Chew your food well for easier digestion. If nausea is a problem in the morning, try eating dry foods before getting up . Drink cool, clear, unsweetened fruit juices, such as apple or grape juice . Breathe deeply and slowly when you feel nauseated Rest but do not lie flat for at least 2 hours after you finish a meal. Pain Chemotherapy drugs can cause some side effects that are painful. The drugs can damage nerves, leading to burning, numbness, or shooting pain, most often in the fingers or toes. Some drugs can also cause mouth sores, headaches, muscle pains, and stomach pains. Hair Loss Hair loss (alopecia) is a common side effect of chemotherapy, but not all drugs cause hair loss. Hair loss can occur on all parts of the body, including the head, face, arms and legs, underarms, and pubic area. The hair usually grows back after the treatments are over.
Anemia Chemotherapy can reduce the bone marrow's ability to make red blood cells, which carry oxygen to all parts of your body. When there are too few red blood cells, body tissues do not get enough oxygen to do their work. This condition is called anemia.
Infection Chemotherapy can make you more likely to get infections. This happens because most anticancer drugs affect the bone marrow, making it harder to make white blood cells (WBCs), Blood Clotting Problems Anticancer drugs can affect the bone marrow's ability to make platelets, the blood cells that help stop bleeding by making your blood clot. Mouth, Gum, and Throat Problems Good oral care is important during cancer treatment. Some anticancer drugs can cause sores in the mouth and throat, a condition called stomatitis or mucositis. Anticancer drugs also can make these tissues dry and irritated or cause them to bleed.
