The stem cell rescue treatment that I'll undergo is officially known as autologous stem cell transplant, autologous meaning that it is a transplant of my own cells. I explained it pretty thoroughly in the first post, but I'll go over it again. What they will do is bank a whole lot of my blood stem cells before I have any treatment. Then I get 2-4 rounds of normal dosages of chemotherapy. After I've had the normal chemotherapy I come in for a single session of high dose chemotherapy. The high dose chemotherapy is necessary because when a recurrence of cancer occurs it is stronger than the first time, so stronger medicine is needed to overcome it. The high doses of chemotherapy will eliminate the cancer but it will also eliminate all my bone marrow cells, so I will have almost no immune system function. That's where the stem cells that they collected before treatment come in. After the high dose chemotherapy, they put the blood stem cells that they collected back into my body and this allows my body to recover and start making more blood cells in a fraction of the time it would take without the stem cell transplant. A really good site with more and more thorough information is here.
After getting the stem cells back, I still have to stay in the hospital for a few weeks until I've created enough blood cells to have a healthy enough immune system to leave. One interesting side effect of the treatment is that it will completely kill off all of my immunizations, so about a year after treatment I will have to get all of the immunizations over again. Sadly, because my immune system will be compromised for a few months after the stem cell rescue, I won't be able to go to crowded places such as school for a few months. Given the timeframe of everything, that means I will most likely not be able to go to any more school this year. I'm pretty upset about that, it will make it a lot harder to keep up with work, and I won't be able to experience the everyday routine of going to school and seeing friends and teachers. I'll still be able to see people, but seeing people in school and participating in class is something I'll miss.
