There are many types of cancers, as well as many types of treatments. One of the most well-known types of treatments would be chemotherapy. Chemotherapy can be used for a wide range of different types of cancers and diseases, and each of the different types of cancers or diseases requires a different group, and sometimes a different order, of chemicals to properly treat the cancer or disease . These chemicals include: alkylating agents, antimetabolites, anthracyclines, topoisomerase inhibitors, mitotic inhibitors, corticosteroids, etc. Each of these medications listed above has its own type(s) of cancer or disease(s) that it can help treat. Some of these cancers include: leukemia, lymphoma, Hodgkin's disease, multiple myeloma, sarcoma, as well as types of lung, breast, intestinal tract, prostate, gastrointestinal, and ovarian cancers. . However, these chemicals and chemical mixtures can have their side effects. Although chemotherapy saves lives, like other medications, it has its side effects. The side effects of chemotherapy, however, are more extreme than what you would see on the back of a medicine bottle. The most common side effects of chemotherapy are nausea and vomiting, fatigue, hair loss, pain; such as headaches, muscle pain, stomach pain, and pain caused by nerve damage such as burning, numbness, and shooting pain, all of which are most commonly felt in the fingers and toes ; sores in the throat or mouth, diarrhea, constipation and blood disorders. There is a specific side effect that worries patients called chemobrain. Chemobrain may be noticed by patients before, after, or during chemotherapy. Chemobrain is what happens when a cancer patient develops a cloudy memory. Cancer survivors who have, or had, middle of paper... are only succeeding, and that cure is chemotherapy. Chemotherapy has its side effects, but for the most part, I believe the mental, emotional, and physical pain and suffering are worth it to survive and overcome such a tragedy. Unfortunately, the only cure we have for these diseases can cause things like chemo brain which affects the memory of cancer patients and survivors. Chemobrain can make simple things more difficult for cancer survivors. Although these cancers and diseases are very deadly, scientists, chemists and oncologists are working extremely hard to make them more survivable than they already are. There are ways to treat or prevent these diseases naturally by simply eating healthy. They are also attempting to advance mixtures and uses of chemicals to treat and prevent cancer and previously listed diseases..
