What is Chemotherapy
Ways to Treat Cancer using Chemotherapy, How it Works, Internal Damage
In treating physical diseases, probably the most common form of therapy is chemotherapy, or drug therapy. Some physical conditions, where chemotherapy is not the best option, can be corrected through surgery while others may be effectively treated by radiotherapy. Chemotherapy is frequently used in the treatment of cancer, often in combination with surgical treatment and radiotherapy. Chemotherapy uses powerful anticancer drugs that travel through the bloodstream, making it potentially useful for cancers that have spread. There about 50 different chemotherapeutic drugs that combat cancer, generally administering more than one drug at a time because the drugs are more powerful when combined. The drugs can be taken orally or injected into the bloodstream. They interfere with cancer designed research studies that test promising new cancer treatments. Patients who take part in research may be the first to benefit from improved treatment methods. These patients also can make an important contribution to medical care because the results of the studies may help many people and help scientists learn more about chemotherapy and its possibilities. Cons of Chemo As stated, one of the most common treatments for cancer is chemotherapy, and since it kills some normal cells at when this happens there could quite possibly be no drugs effective against this tumor. Some side effects go away fairly rapidly, others take months or years to disappear completely. Sometimes the side effects can last a lifetime, as when chemotherapy causes permanent damage to the heart, lungs, kidneys, or reproductive organs. Certain types of chemotherapy occasionally may cause delayed effects, such as a second cancer, that show up many years later the same time that it can kill cancerous ones, it has the ability to cause many side effects. These side effects are often very serious. Some side effects of chemotherapy are: Your immune system could weaken immensely, which would cause you to be very susceptible to infection and other diseases Internal bleeding Diarrhea Nausea Vomiting Mouth sores Hair loss Insufficient oxygen in the blood (anemia) Sometimes tumors develop a resistance to certain drugs after exposure to it just once.
