Medical sciences has been improved greatly, many of the life threatening diseases which were incurable in the past are now curable. Diseases such as cancer were considered the most lethal one that cannot cured no matter what. But now with new developments that are made in medical sciences cancer is no more incurable. Chemotherapy, radiation and surgery have made it possible to treat cancer. This treatment is not absolute but the results are much satisfying than when there was no treatment at all.
Stem cell transplantation
Stem cell transplantation has been carried out since 1979. In this medical treatment the stem cells is transplanted in the human to cure types of cancer which is mostly related to blood such as leukemia and myeloma. Stem cells can be said as the blood cells at their initial or dormant state. Stem cells and blood cells are produced by the bone marrow. Stem cells remain stored in the bone marrow until it is necessary to replace other cells and the cycle or replacement goes on for other stem cell to replace the previous.
Immune disorders which are inherited by the patient from their parents and grand-parents are possible to treat now by stem cell transplantation. Doctors are utilizing stem cells to help the human body fight against the cancerous cells.
As the treatment for cancer proceeds patient’s body faces problems as chemotherapy and radiation is done to kill the cancerous cell. This treatment process not just kills the cancer cells but along with it healthy body cells are also destroyed. Death of the bone marrow cells is the result of chemotherapy and radiation, stem cell transplantation plays an important part in the regeneration of bone marrow cell. It is possible that the cells implanted are from the patient himself that is stem cells can be collected and implanted back after the treatment.
Most of the time the cells are received from a donor whose cells are compatible with the recipient’s cells so that they can be transplanted in the patient, it is possible that the recipients body may reject the cells or donor cell’s immune system may attack the patient’s cells. So care is taken to determine the donor.
