An external radiation therapy session lasts 30 minutes to an hour. Most of that time is spent getting you into the correct position for treatment. The actual treatment takes five minutes or less.
How long does it take to recover from radiation treatment?
The general effects of radiation therapy like fatigue, nausea, and headaches resolve fairly quickly after treatment. Your body just needs time to process the radiation but can recover within a few weeks. Delayed side effects of radiation therapy, on the other hand, may require further treatment to alleviate.

What is the average length of time for radiation treatment?
Each radiation therapy treatment takes about 10 minutes. Radiation therapy to try and cure cancer is usually delivered daily, Monday through Friday, for about five to eight weeks. Weekend breaks allow normal cells to recover. Shorter durations of radiation therapy may be used to relieve symptoms.
How many hours does radiation therapy take?
Your entire visit may last from 30 minutes to an hour. Most of that time is spent placing you in the correct position. Certain types of radiation may take longer. Your visit may also take longer if your treatment team needs to take and review x-rays.
How many sessions of radiation therapy is needed?
Most people have 5 treatments each week (1 treatment a day from Monday to Friday, with a break at the weekend). But sometimes treatment may be given more than once a day or over the weekend.
How long is radiation therapy for cancer?
Treatments are usually given five days a week for six to seven weeks. If the goal of treatment is palliative (to control symptoms) treatment will last 2-3 weeks in length. Using many small doses (fractions) for daily radiation, rather than a few large doses, helps to protect the healthy cells in the treatment area.
What can I expect after my first radiation treatment?
The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area. Late side effects can take months or even years to develop.
How long does it take for radiation to shrink tumors?
At the same time, if a cell doesn't divide, it also cannot grow and spread. For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).

“When patients are treated with modern external-beam radiation therapy, the overall cure rate was 93.3% with a metastasis-free survival rate at 5 years of 96.9%.
How many radiation treatments can you have in a lifetime?
Most guidelines are given as annual radiation limits, usually at 20 millisieverts (mSv/y). Some authors have suggested, however, that a lifetime maximum radiation limit of 400 mSv also is appropriate. Guidelines do not specify how much radiation patients may receive from medical procedures.
Is radiation worse than chemo?
The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

How to eradicate tumors in radiation therapy?
In order to eradicate a tumor in radiation therapy while staying within the desired therapeutic index, several factors play an important role including dose of radiation, time of dose delivery, and fractionation of dose. As described in a previous chapter, dose is a physical quantity of radiation. Dose refers to the amount of energy absorbed from a beam of radiation at a given point in a medium. The two SI units of dose are in gray (Gy) or centigray (cGy). 1 Gy = 1 J/kg (joule/kilogram) and 1 cGy = 0.01 J/kg, so 1 Gy = 100 cGy.
Why do radiation doses have to be fractionated?
Fractionation of radiation doses spares slowly responding normal tissues as they have a greater capacity for tissue repair than rapidly responding tumor tissue. Tissue repair and the sparing of slowly responding normal tissues is the reason that most radiation therapy is delivered in multiple small fractions.
What is TDF in radiotherapy?
In 1973, Orton and Ellis developed the concept of time dose factor (TDF) which takes into account time, fractions, and interval between fractions. The NSD concept in radiotherapy has thus become simplified by the introduction of time, dose, and fractionation factors, which are proportional to partial tolerance, but not dependent upon any specific NSD value. Partial tolerance is related to NSD by a factor which is a function of overall time, the dose per fraction, and the fraction pattern. This factor is called the time, dose, and fractionation (TDF) factor. The TDF is related to the NSD as follows:
What is fractionation of radiation?
Time, dose, and fractionation refer to the schedule of the radiation treatments to be administered. The probability of tumor control obviously increases with a higher total dose, but so does the issues of early and late complications. To mitigate this problem, multiple fractions of dose with specific intervals are delivered. The different intervals and doses per fraction should be specifically based upon the area and size treated. When dose is administered in fractions and not all at once, it is referred to as dose fractionation. Fractionation of dose in radiotherapy is largely concerned with improving tissue tolerance. Much larger cumulative doses can be administered with less long-term adverse effects if the total dose is divided into fractions or increments and spread over a period of days or weeks.
Why fractionate doses in radiotherapy?
Fractionation of dose in radiotherapy is largely concerned with improving tissue tolerance. Much larger cumulative doses can be administered with less long-term adverse effects if the total dose is divided into fractions or increments and spread over a period of days or weeks.
How many rads in a day?
Strandquist’s results indicated that 2,000 rad in 1 day was equivalent to 3,000 rad in 4 days, 4,000 rad in 11 days, 5,000 rad in 25 days, and 6,000 rad in 45 days. The take-home point from Strandquist’s efforts was that total dose is most meaningful when the overall treatment time is known. Strandquist plot.
What is the nominal standard dose?
This led Ellis and colleagues in 1967 to develop the nominal standard dose (NSD) system which takes into account both time and number of fractions. where T is the overall time in days and N is the number of fractions.
When were multifractions used in radiation therapy?
The multifraction regimens commonly used in conventional radiation therapy are a consequence largely of radiobiologic experiments performed in France in the 1920s and in the 1930s.
Why prolong treatment?
The advantages of prolongation of treatment are to spare early reactions and to allow adequate reoxygenation in tumors. Excessive prolongation, however, allows surviving tumor cells to proliferate during treatment.
Why does dividing a dose into several fractions increase damage to the tumor?
At the same time, dividing a dose into several fractions increases damage to the tumor because of reoxygenation and reassortment of cells into radiosensitive phases of the cycle between dose fractions. FIGURE 23.1 Conventional multifraction radiotherapy was based on experiments performed in Paris in the 1920s and in the 1930s.
What is the difference between early and late response?
Clinical and laboratory data suggest that there is a consistent difference between early- and late-responding tissues in their responses to changing fractionation patterns. If fewer and larger dose fractions are given, late reactions are more severe, even though early reactions are matched by an appropriate adjustment in total dose. This dissociation can be interpreted as differences in repair capacity or shoulder shape of the underlying dose-response curves. The dose-response relationship for late-responding tissues is more curved than that for early-responding tissues. In terms of the linear-quadratic relationship between effect and dose, this translates into a larger α/β ratio for early effects than for late effects. The difference in the shapes of the dose-response relationships is illustrated in Figure 23.6. The α/β ratio is the dose at which cell killing by the linear (α) and the quadratic (β) components are equal. (See Fig. 23.12)
Can radiotherapy be combined with chemotherapy?
It might be anticipated, however, that similar considerations would apply to chemotherapy or to a combination of radiotherapy and chemotherapy. There is evidence in some human malignancies that radiotherapy produces poorer results if preceded by a course of chemotherapy.
Is fractionation of radiation dose better than single large dose?
The reasoning may be flawed, but the conclusion proved to be valid: Fractionation of the radiation dose produces, in most cases, better tumor control for a given level of normal tissue toxicity than a single large dose.
