    Study Notes

    Internal Radiation Therapy

    • Internal radiation therapy involves implanting or introducing a radioactive substance into the body to kill cancer cells and prevent or slow the spread of the disease.
    • There are different types of internal radiation therapy.

    Effectiveness of Treatment

    • Estimated to take effect about 4 weeks after the initiation of treatment.
    • In order to keep pace with the rapid growth of tumor cells, a more rapid delivery of treatment may be needed.

    Continuous Low Dose Irradiation

    • Tends to synchronize the cell cycle and allows sublethal damage repair.

    Disadvantages of Bracytherapy

    • Inhomogeneity.

    Radiation Therapy

    • Can cause anxiety and concern in some people.
    • Has various uses in treating cancer and can help achieve complete remission in some cases.
    • Can be costly.
