What do radiation oncologists do before performing radiation procedures?
Before performing radiation procedures, radiation oncologists use software to carefully map out where they will deliver radiation to their patients. They also decide which type of radiation therapy to use. The two main types are external beam radiation t herapy and internal radiation therapy.
How does radiation therapy work against cancer?
How Radiation Therapy Works Against Cancer. At high doses, radiation therapy kills cancer cells or slows their growth by damaging their DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and removed by the body. Radiation therapy does not kill cancer cells right away.

Radiotherapy may be used in the early stages of cancer or after it has started to spread. It can be used to: try to cure the cancer completely (curative radiotherapy) make other treatments more effective – for example, it can be combined with chemotherapy or used before surgery (neo-adjuvant radiotherapy)
Can you skip a day of radiation?
Answer: Missing one day or even two days in a row over the course of a six-to-eight-week course of radiation really doesn't matter. But we do know from studies that have been done in the past that if radiation is given with a significant stop in the middle -- a week or two weeks -- it actually is less efficient.
What happens if radiation does not work?
If radiotherapy doesn't kill all of the cancer cells, they will regrow at some point in the future. We have more information about radiotherapy treatment.

Radiation therapy used this way is called intraoperative radiation. With this technique, doctors can more easily protect nearby normal tissues from radiation. 3 After surgery to kill any cancer cells that remain.

What is the hemoglobin level in radiation?
Based on data from Beth Israel Medical Center on the prevalence of anemia, hemoglobin levels within the range of 10 to 12 g/dL are common in the radiation oncology setting. Ongoing research efforts seek to characterize the relationship between the extent and rate of hemoglobin decline and the development of fatigue, as well as the influence of anemia on other quality of life measures, in the cancer population. Strategies such as hypoxic-cell sensitizers (mitomycin) and anemia-directed therapies (erythropoietin, blood transfusion) are reasonable interventions in patients planning to undergo radiation therapy. Managing mild-to-moderate anemia may potentially influence both tumor response and patient quality of life.
What are the symptoms of cancer?
Anemia, the most frequent hematologic abnormality in the cancer population (including patients presenting for or undergoing radiation therapy) is associated with symptoms (eg, fatigue, dizziness, shortness of breath) that may greatly impair quality of life. At the time of cancer diagnosis, this condition is typically categorized as "anemia of chronic disease"; it may be aggravated over time by underlying disease progression, surgical blood loss, or subsequent chemotherapy and/or radiation therapy.
Can radiation oncologists cause anemia?
Radiation oncologists often "inherit" anemia that has developed from surgical blood loss, myelotoxic chemotherapy, and/or advanced disease. The prevalence of anemia among patients presenting for radiation therapy is not well documented, but it is generally believed that a substantial proportion of these patients do become anemic. A recent literature review revealed a relatively high incidence of mild-to-moderate anemia in patients receiving single-agent or combination chemotherapy for nonmyeloid malignancies. [15] A similar assessment in the radiation oncology setting is not available.
Can anemia improve energy levels?
However, this perception is changing among medical oncologists. Recent studies indicate that correcting mild-to-moderate anemia in cancer patients can improve energy levels, [1,2] which may have a profound effect on functional capacity, sense of well-being, and ultimately, the desire to continue chemotherapy.
