This treatment course of five days per week for several weeks is the most common scenario for radiation treatments, although there are several exceptions. For certain tumors, treatments may be less than five days per week and only last for a week or two. In other situations, such as for certain brain tumors, a single treatment may be recommended.
Can brain cancer be cured with radiation?
Whole-brain radiation is most often used to treat cancer that spreads to the brain from some other part of the body and forms multiple tumors in the brain. Traditionally, radiation therapy uses X-rays, but a newer form of this treatment uses proton beams. Proton beam therapy allows doctors to control the radiation more precisely.

Types of Radiation Therapy for Brain Tumors
There are 2 main types of therapy. You may get both types. They include:
External beam radiation therapy (EBRT)
There are several types of EBRT. The goal is to target the tumor and limit damage to nearby healthy brain cells. To limit the harm, your healthcare provider may use special types of EBRT such as:
Brachytherapy
For this treatment, the radiation is placed very close to or inside the tumor. This is done during surgery. The radiation the implants give off travels a very short distance. This helps limit the effect on nearby healthy tissue.
Brain Radiation Side Effects
Generally, side effects from radiation treatment are grouped into two categories:
Radiation necrosis
Sometimes dead brain tissue forms at the site of the radiation. This is called radiation necrosis. The mass of dead brain tissue comes from both cancer cells and healthy cells. Radiation necrosis can take anywhere from months to years to develop.
Risk of future cancer
Radiation can damage the DNA in healthy cells. As a result, you have a small risk of a second brain cancer after brain radiation. This second cancer usually occurs many years later. Talk to your radiation oncologist about the risks and benefits of radiation therapy.
The Radiation Team
Treatment planning for radiation therapy includes mapping to pinpoint the exact location of the brain tumor using X-rays or other images.
How often do you get radiation treatment?
How often you have radiation therapy will depend on the size and type of tumour, but usually it is given once a day, from Monday to Friday, for several weeks. During treatment, you will lie on a table under a machine called a linear accelerator. Each daily treatment will last for about 10–15 minutes.
What is the treatment for brain cancer?

How many people are diagnosed with cancer each year?
Cancer is a devastating diagnosis, affecting approximately 14 million new people per year per the National Library of Medicine. As technology and research has advanced, the possibility of survival has increased in tandem with the application and understanding of radiation therapy. Out of the 14 million individuals diagnosed with cancer, a significant percentage may achieve cure/remission, and depending on the type of radiotherapy used, long-term survival rates may increase. Unfortunately, many misconceptions continue to surround radiotherapy, including the duration of a radiation treatment course and whether a specific type of cancer is susceptible to radiation. In order to clarify some of those misconceptions this article aims to clarify a few points about radiotherapy treatment and how frequently it is used.
What is the purpose of digital imaging and radiation therapy?
Prior to receiving treatment, extensive testing and digital imaging are used to develop a specific treatment plan that will target the cancer, based on the type, stage and patient characteristics. Your physician will be able to discuss whether radiation therapy is indicated for your particular type of cancer.
Can a deeper tumor be treated with a beam?
For example, a deeper tumor may require a more-focused beam for a shorter period, but a larger, shallow tumor may be treated the same focused beam for a longer period. Moreover, the location of the tumor and its proximity to other sensitive body tissues will affect radiotherapy planning and treatment.
Can side effects affect frequency of treatment?
Side effects and their severity also influence the frequency of treatment. While generalized side effects exist, different patients may respond to the same treatments quite differently. Severe side effects may warrant an altered treatment plan or additional medications to reduce side effect symptoms.

What is the most common brain tumor in adults?
Glioblastoma (GBM) is the most common primary brain tumor in adults, with an incidence rate among elderly patients of 70 years and older of 17.5 per 100,000 person-years, and a relative risk of 3–4 times compared with young adults [4]. RT is frequently used in older patients with GBM.
How long do brain metastases last?
WBRT has classically been the standard treatment for patients with brain metastases with a reported median survival of 3–6 months [92].
What is the incidence of lymphoma?
The incidence of primary central nervous system lymphoma (PCNSL), a lymphoproliferative disorder that may affect the brain, eyes, spinal cord or leptomeninges in absence of systemic involvement, is 3–4% of all primary brain tumors [ 68 ]. PCNSL has a predilection for the elderly population, with a median age at diagnosis of 55 years and a peak incidence in the sixth and seventh decades of life [ 69, 70 ]. Whole brain radiation therapy (WBRT) was historically the modality of choice to treat PCNSL until the early 1990s. PCNSL responds relatively quickly to RT, and the complete disappearance of enhancing tumor masses is frequently observed. However, local recurrence and intracranial progression at distant brain sites occurs within few months, and the reported survival outcome of patients treated by radiation alone is relatively poor [ 71, 72 ].
Can WBRT be withheld?
While these studies indicate that WBRT can be withheld and a radiological surveillance policy adopted for older patients who achieve complete remission, RT should be considered for those with residual disease after chemotherapy or in patients whose medical comorbidity precludes chemotherapy . An alternative approach to standard WBRT in older patients is represented by the use of low-dose consolidative RT, in the effort of maintaining the potential benefit of radiation while limiting the risk of neurotoxicity [ 89, 90 ]. In a phase II study conducted at Memorial Sloan Kettering, 52 patients were treated with WBRT, using 23.4 Gy in 1.8 Gy fractions after hd-MTX, rituximab, vincristine and procarbazine, and 2 cycles of consolidative high-dose Ara-C. Results, with rigorous neurocognitive testing, showed very good disease control (35% of patients relapsed) with minimal neurotoxicity [ 89 ]. In another retrospective series of 33 patients with PCNSL who received consolidation WBRT after HD-MTX, Ferreri et al. [ 90] observed no significant difference in disease control between patients who received WBRT doses ≥40 Gy or doses of 30–36 Gy (relapse rate, 46 vs. 30%; 5-year failure-free survival, 51 vs. 50%; p = 0.26). Currently, the randomized phase II study RTOG 1114 is exploring the effects of rituximab, methotrexate, procarbazine, vincristine and cytarabine with and without low-Dose WBRT for PCNSL. A few series suggest that the use of partial brain irradiation may be considered in patients with a single tumor [ 72, 91 ]; however, in current clinical practice WBRT remains the standard technical approach (including optic nerves and with a lower limit at C1-C2).
Is SRS a good treatment for brain metastases?
In summary, data extracted from randomized trials and retrospective studies suggest that SRS is a reasonable approach to older patients with a limited number of brain metastases with both survival benefit and toxicity profile similar to those observed in young adults. Future randomized studies need to investigate the advantages of such approach in the elderly in terms of survival and quality of life over other treatment options.
Can chemo be used for gliomas?
The use of chemotherapy as an alternative to RT in older patients with malignant gliomas has been addressed in a few prospect ive and randomized studies [ 49, 51 – 53] (Table 2 ). In the German Neuro-oncology Working Group (NOA) phase 3 trial (NOA-08), 373 patients older than 65 years with histologically confirmed anaplastic astrocytoma or GBM, and a KPS score ≥ 60, were randomly assigned to receive dose-dense TMZ (1 week on, 1 week off schedule, 100 mg/m 2 given on days 1–7) or standard RT [ 53 ]. Median event-free survival time was 3.3 months for patients treated with TMZ and 4.7 months for those treated with standard RT (hazard ratio 1.15, 95% CI 0.92–1.43, p = 0.03), respectively. Median survival was 8.6 months for patients treated with TMZ and 9.6 months for those treated with standard RT (hazard ratio 1.09, 95% CI 0.84–1.42, p = 0.03), respectively, indicating that chemotherapy was non-inferior to standard RT. Analysis of health-related quality of life scales showed no significant differences between groups; however, grade 2–4 adverse events were more frequent in the TMZ group. A striking finding of the study was the predictive role of O6-methylguanin-DNA-methyltransferase (MGMT) promoter methylation status on survival outcomes. MGMT promoter methylation was associated with longer survival (median 11.9 months vs 8.2 months; hazard ratio 0.62, 95% CI 0.42–0.91, p = 0.014) and longer event-free survival (median 5.7 months vs 3.5 months; hazard ratio 0.5, CI 0.36–0.68, p < 0.001) than unmethylated status. The presence of MGMT promoter methylation was associated with better event-free survival time only in patients who received TMZ, but not in patients who received RT, whereas the opposite was true for patients with unmethylated tumor.
How long does radiation treatment last?
What Happens During Radiation. The treatment is normally Monday through Friday and lasts about 45 minutes. A lot of time is spent getting your body in the right position, so the radiation hits its desired locations. You lay down on a custom-molded table. A technician positions your body using lasers and measurements.
How long does it take for radiation to hit your body?
This may seem scary, but this ensures the radiation does not hit healthy areas. The radiation takes a couple of minutes. You can sense when the radiation hits your body if you receive radiation to your brain.
Can radiation cause fatigue?
Radiation side effects are different for each person. You may be able to exercise or perform your ‘normal’ activities. Or you may not. Side effects also tend to get worse as more treatments are given. I lost my hair, experienced a great deal of fatigue and nausea, and skin dryness on treated areas. When these changes happen, acknowledge your side effects and react. No one expects you to go through treatment and act like it doesn’t affect you. Once treatment is over, your body quickly adjusts to its normal self.
Does radiation cause hair loss?
Radiation to your brain causes hair loss, but over time it grows back. As your hair grows again, so will you. Remember, during and after radiation treatment, listen to your body, ask questions, acknowledge side effects and adjust.
Why do people undertreat radiation?
Because of their benign histologic nature there is sometimes a tendency to undertreat them because of the fear of long-time side-effects, particularly the effects of radiation therapy. Today’s technology makes most of these fears unfounded.
Can a tumor be removed with radiation?
Tumors of this size cannot often be removed, and radiation therapy may be beneficial. Because these tumors are benign, very focal irradiation is appropriate; as in meningiomas, modern techniques that spare normal tissue are optimal.
Can a tumor be resectable without surgery?
For tumors in more critical areas, or if documented progression takes place, surgery is a very successful treatment if a complete resection can be performed; in this case, the patient needs no further treatment. Many lesions , however, particularly those in the base of the brain or around the optic nerves, are not resectable without major risks.
