Many cancer patients are advised to take chemotherapy to control the spread of cancer cells. However, they also cause certain damages to other normal cells in the body. Knowing about the advantages and disadvantages of the therapy will prepare the patient to mentally accept the disadvantages and to recover from the side effects faster.
The chemical agents used for the therapy will kill the cancer cells and reduce the spread of cancer to other parts of the body. The patient will be able to live normally after the chemo treatment. The chemotherapy drugs are available in the form of intravenous injections or as pills. These drugs, when used in combinations, are highly effective in controlling cancer. The patient can be completely cured of cancer with the right type of chemotherapy. Even the smallest cancer cells, which are difficult to detect by tests will be destroyed by chemo drugs. In the case of large tumors, chemotherapy will help to reduce the size of the tumors and this will make surgery less invasive and less time taking. The new chemo drugs are very specific in action and are more effective.
As there are different types of drugs used for chemotherapy the side effects experienced by the patients may vary from person to person. There will be emotional and physical changes during or after chemotherapy. Your body will be more prone to infections. The symptoms of side effects will start within 24- 48 hours after the exposure to the chemo drugs. The disadvantage of this treatment is that the chemo drugs can damage sensitive cells like cells inside the mouth and digestive system, the bone marrow cells and hair follicles, as a result, the person will experience nausea, weight loss, memory loss, hair loss, etc. The exposure to these drugs can also cause fertility problems in men and women.
Most of the damaged cells will return to normalcy after the chemotherapy. There are medications available to reduce the side effects.
