Using many small doses (fractions) for daily radiation, rather than a few large doses, helps to protect the healthy cells in the treatment area. The break from treatment on weekends allows the normal cells to recover. It is very important to finish all sessions of radiation therapy.
Why do I have to take a break in treatment?

What happens during radiation therapy treatment?
What happens during your radiation therapy treatment depends on the kind of radiation therapy you receive. External-beam radiation therapy delivers radiation from a machine outside the body. It is the most common radiation therapy treatment for cancer. Each session is quick, lasting about 15 minutes.
How does radiation kill cancer cells?
But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die. Nearby normal cells can also be affected by radiation, but most recover and go back to working the way they should.
Does interruption of radiation therapy increase the risk of cancer recurrence?
Interruption of radiation therapy risks cancer recurrence. This is attributed to tumor repopulation, which can accelerate after treatment initiation. "We previously conducted a study that demonstrated a statistically significant relationship between lower socioeconomic status and non-compliance," said Nitin Ohri, M.D., attending physician,...
Can you take a break during radiation?
It's best to continue your treatment without interruption. But an occasional short-term break of a day or two off from treatment is unlikely to reduce the effectiveness of radiation therapy. So if you need to take a short break, let your doctor know and get back on schedule as soon as possible.
What happens if radiation treatment is interrupted?
Missed Radiation Therapy Sessions Increase Risk of Cancer Recurrence. Patients who miss radiation therapy sessions during cancer treatment have an increased risk of their disease returning, even if they eventually complete their course of radiation treatment, according to a new study.
How long after radiation do you start to feel better?
Most side effects go away within 1–2 months after you have finished radiation therapy.
Why is radiation treatment so tiring?
During treatment, some patients may feel particularly tired after receiving radiation therapy. Fatigue can result when the immune system responds to an injury or wound. This occurs because the immune system uses energy to fight infection and sends out substances that make the body want to rest so it can heal.
Can you pause radiotherapy?
Good clinical practice dictates that radical courses of radiotherapy treatment should not be interrupted; however, where interruptions are unavoidable, compensatory treatment is required.
Is it OK to miss one 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 should you not do during radiation?
Avoid raw vegetables and fruits, and other hard, dry foods such as chips or pretzels. It's also best to avoid salty, spicy or acidic foods if you are experiencing these symptoms. Your care team can recommend nutrient-based oral care solutions if you are experiencing mucositis or mouth sores caused by cancer treatment.
Do tumors grow back after radiation?
Normal cells close to the cancer can also become damaged by radiation, but most recover and go back to working normally. If radiotherapy doesn't kill all of the cancer cells, they will regrow at some point in the future.

When radiation is combined with surgery, it can be given: 1 Before surgery, to shrink the size of the cancer so it can be removed by surgery and be less likely to return. 2 During surgery, so that it goes straight to the cancer without passing through the skin. 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.

How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.
What is the treatment for cancer that has returned?
To treat cancer that has returned (recurred) If a person's cancer has returned (recurred), radiation might be used to treat the cancer or to treat symptoms caused by advanced cancer. Whether radiation will be used after recurrence depends on many factors.
How does cancer spread?
Cancer can spread from where it started to other body parts. Doctors often assume that a few cancer cells might already have spread even when they can’t be seen on imaging scans like CT scans or MRIs. In some cases, the area where the cancer most often spreads to may be treated with radiation to kill any cancer cells before they grow into tumors. For instance, people with certain kinds of lung cancer may get radiation to the head, even when there is no cancer known to be there, because their type of lung cancer often spreads to the brain. This is done to help prevent cancer from spreading to the head even before it can. Sometimes, radiation to prevent future cancer can be given at the same time that radiation is given to treat existing cancer, especially if the area the cancer might spread to is close to the tumor itself.
How many people with cancer get radiation?

How long does it take for radiation to cause side effects?
Late side effects can take months or even years to develop. They can occur in any normal tissue in the body that has received radiation.

How are radiation beams absorbed?
The beams pass quickly through the body and are absorbed by special shields positioned around the patient. Some cancers are treated with internal radiation therapy, in which radioactive material, sealed in a container, is implanted next to or inside a tumor.
Does radiation damage DNA?
Because cancer cells divide rapidly, they’re more likely to succumb to DNA damage, but radiation can damage DNA in normal cells as well. The damage that radiation therapy does to normal cells may lead to a variety of side effects, which generally improve over time.
Do implants have radioactive material?
As with patients receiving temporary implants, the body fluids and personal items of patients with permanent implants are not radioactive. Because it is low-level, the radiation usually doesn’t travel much beyond the area being treated, so there’s little chance of exposing others to radiation.
