However, radiation is generally used after surgery when a patient is deemed to be at
high risk for tumor recurrence in the surgical bed.

This form of treatment is also called radiation therapy. It is One of three primary means
of treating cancer - Answer-Radiation Oncology

A physician who specializes in the treatment of malignant disease with radiation. -
Answer-Radiation Oncologist

Cancer treatment plans consists of: - Answer-Diagnostic: diagnostic radiographs using
xrays, ct, MRI, PET, and sonograms are obtained to acquire info about the location and
anatomic extent of the tumor.

Biopsy: a tissue specimen is removed surgically

Pathology: A pathologist examines the tissue to determine whether the lesion is
cancerous. If cancer is diagnosed, treatment plan is determined by oncologists.

Patient and Oncologist discuss options and choose a course of treatment

Typical course of treatment: - Answer-- Most often delivered on a daily basis (M-F) for
2-8 weeks
- Length and dose are variable, dependent on if it is for cure or palliation treatment.
- Dose can range from 2000 cGy to 7600 cGy
- Delivered by small doses at a time (fractionation)

Fractionation can help minimize the acute toxic effect a patient experiences during
treatment and possible long-term effects of treatment. True or false - Answer-True

, What is consisted of the Radiation Oncology Team? - Answer-- Radiation Oncologist:
prescribes the quantity of radiation & determines the anatomic regions to be treated.

1934 - Joliot & Joliot-Curie: Production of artificial
radioactivity
1939 - Lawrence & Stone: Treatment of cancer PT
with neutron beam from cyclotron
1940 - Kerst: Construction of betatron

teletherapy units
