Brain Cancer Guide

Radiation therapy is a common treatment option for brain cancer that involves the use of high-energy radiation to kill cancer cells. Although radiation therapy is effective, it can also cause side effects that vary in intensity and duration.

​

Here is a week-by-week summary of anticipated side effects of radiation therapy for brain cancer:

​

Week 1-2:

The most common side effects during this period are fatigue, headache, and nausea. Patients may also experience hair loss in the treated area, although this may take several weeks to become apparent.

​

Week 3-4:

As treatment progresses, patients may experience additional side effects such as skin irritation, dry mouth, and difficulty swallowing. They may also notice changes in taste and smell, as well as decreased appetite.

​

Week 5-6:

During this period, the side effects of radiation therapy may become more severe. Patients may experience increased fatigue, headaches, and nausea. They may also experience swelling and inflammation of the brain, which can cause seizures or other neurological symptoms.

​

Week 7-8:

As treatment comes to an end, patients may experience some lingering side effects, such as fatigue, skin irritation, and hair loss. These side effects typically subside over time, although some patients may experience long-term effects such as cognitive changes or memory problems.

​

It's important to note that not all patients will experience the same side effects, and some may experience no side effects at all. The severity and duration of side effects can also vary depending on the dose and length of radiation therapy. Patients should talk to their healthcare provider about any concerns they have regarding radiation therapy and its potential side effects.
