The human body is made up of nearly 100 trillion cells. These cells work day and night to keep the body working properly. If a cell becomes ill, the cell automatically begins to repair itself. But when cancer enters the body the cell no longer has the ability to heal itself so it stops working and begins to affect other cells in the human body. As the cancer spreads, it replaces healthy cells with cancerous cells. If nothing is done to stop the cancerous cells, the body stops functioning, it begins to shut down and eventually dies. To help the body fight cancerous cells, radiation is introduced into the body via radiation therapy.
Radiation therapy is essentially a burst of radioactive beams designed to target only the cancerous cells. The radioactive beams are given to the patient in small doses over a period of weeks. This allows the good cells to rejuvenate as the bad cells die off. With any luck, the cancer will completely die off and the patient will be allowed to return home where he (or she) can begin to recover.
As a radiation therapist, your job will be to make sure the correct burst of radiation is given to the patient. You will also need to make sure the radiation targets the cancerous cells while minimizing its effect on the healthy cells.
