There are many types of cancer. One of the best treatments for cancers is the bone marrow transplantation. This procedure can be extremely painful but can also give great results. This treatment is also called stem cell transplantation. The full array of cancers can be affected by the process. Such are malignant myeloma, leukemia, aplastic anemia, non Hodgkins lymphoma and many other. The recovery from this procedure can sometimes be very long and tiring. So we will try to explain what awaits the patients after the bone marrow procedure. The process of bone marrow starts with the elimination of the complete bone marrow from the patient\'s body. This is done by radiation and chemotherapy. After this, the harvested stem cells are returned back to the patient. This part of the process is named autologous transplantation. Nowadays, doctors try to use as less as chemotherapy and radiation as possible, since they can cause serious discomfort to the patients. But this is only done with patients which are in stronger condition, because some side effects are possible. They do not destroy all the bone marrow and leave just a small portion of it. The chemotherapy has many side effects and one of the most serious is the weakening of the immune system. The immune system is even nonexistent in the first 2-4 weeks after the cell transplant. Because of this, it is important to be in sterile conditions until the stem cells recover. Until this happens, patients are located in rooms with filtered air, cannot be visited by friends and family and will have very limited diet. Patients will have long recovery. Even when they are dismissed from the hospital, they must remain in their homes for the next several months. They cannot return to work before six months and in some cases even a year. There is a possibility of the development of a condition called graft versus host disease. The symptoms will not develop before three months after the surgery. This disease is lethal in every fifth or tenth case, and causes skin rash, nausea, kidney and lung problems, vomiting, dry eyes and jaundice. But the consolation for the people with this condition can be found in the fact that they remain cancer free usually longer than the patients which never develop the disease. The patients who take donor cells usually develop the condition, while the one\'s who use a mix of donor and patient\'s cells always do. Process with the patient\'s cells never produces the graft versus host disease. There is also the possibility of developing the acute disease which can last for 18 months. Although the treatment is long, painful and dangerous, the results may be worth the effort. Know that there are many support groups and doctors which will help you recover from the bone marrow transplantation.
