What does the treatment of cancer mean?
When a cancer patient reaches their "Nadira", it means that the patient's blood number is the lowest as they will be during treatment. The low blood number causes a number of symptoms, including lethargy, but also leave the patient highly sensitive to infection. For this reason, cancer treatment is carefully timed so that doctors know when to expect Nadir, and cancer patients are usually warned in advance of the risks of the Nadir. After Nadira, the patient's blood begins to rise and reduces the risk of danger, and hopefully it announces the return of good health. In order to understand Nadir, it can help know what the "blood number" is. The blood number is performed by a pattern of blood and its use to determine the levels of different blood components in the body, including white blood cells and red blood cells. Chemotherapy reduces the number of blood by disrupting the production of new blood cells in the bone marrow, causing the causing image to decrease because no other cells are produced.
white blood cells are a special concern during chemotherapy because they have the shortest life in the blood and are the first line of body defense against infection. When the blood count begins to reduce, white blood cells usually lead the way and the patient is left defenseless. As the body processes chemotherapy, stem cells in the bone marrow begin to divide again and produce new blood cells and the blood number begins to rise.
The timing of chemotherapy is important. If treatment is administered when stem cells actively produce new white blood cells, this can lead to long -term problems for the patient, including bone loss. Therefore, blood is tested before treatment to determine where the stem cells are in their production cycle, which lasts about 28 days. If more than one treatment is planned in a cycle of chemotherapy, the other treatment is given before the stem cells are fully recovered, ensuring that they are not in active production.
timing of the period of Nadiro varies depending on the drug involved, but the range is the OBVykle seven to 14 days. During the Nadir, patients must avoid any potential sources of infection, as even normal colds can be very serious for a patient with low blood. People also usually feel particularly bad during the Nadira period, which is something friends and family want to keep in mind.
