Are side effects for chemotherapy treatment of brain cancer treatable or reversible?

Yes. Your treatment team can help you with additional medications to ease your experience of any side effects that you may be experiencing during chemotherapy. Some people find that keeping a journal to track your medication and any reactions helps to track side effects, making it easier to report any issues to your doctor.

Additionally, almost all side effects are reversible, meaning they should disappear after a chemo treatment cycle is complete. Some may fade quickly, in a few days, while others may take a few weeks to completely resolve.

Tips from Cancer patients who’ve been there

1. Get some rest

Fatigue is the most common side effect experienced by cancer patients, especially those undergoing chemotherapy. So, get plenty of rest and avoid pushing yourself too hard, even if you feel good. Be patient with yourself and others since it may take some time to get back to your regular energy levels. And, remember that it’s OK to ask for help so that you can take it easy.

2. Stay hydrated

Diarrhea, vomiting and other chemotherapy side effects can cause you to become dehydrated. Not only can this cause you to have low energy, but it can also cause other health issues. So, be sure to drink plenty of water during your treatment. Decaffeinated tea, juices and milk can also help. If you’re having trouble consuming enough liquids or staying hydrated, talk to your care team.

3. Eat when you can

Chemotherapy can cause nausea and appetite loss, so it’s important to eat when you can to avoid becoming malnourished. Keep in mind that many foods may taste different as you go through treatment. For some patients, food may have a metallic aftertaste during and after chemotherapy.

4. Create a sense of normalcy in your routine

Stick to your normal routine as much as possible. That could be something as small as getting dressed up every day, or having a meal with your family. These rituals can help take your mind off cancer.

5. Look to your support and care teams to have your back through treatment

Going through chemotherapy is tough, so look to your family, friends and your care team for support. The doctors and nurses will do everything they can to make you comfortable. But it’s important that you ask questions and voice concerns, so they can help.

6. Keep things around that bring you comfort

Bring your favorite blanket, a yummy snack, your best friend, a good book or whatever brings you the most comfort and keeps you busy while you wait.

7. Stay ahead of your nausea

Many patients experience nausea during and after chemotherapy. So, get your nausea prescriptions filled before you start chemotherapy, and take them before treatments so they kick in before the nausea does. If your nausea medications don’t work, ask your doctor to try a different prescription. It might take a few tries to find the one that works best for you.

Sitting outside and getting some fresh air may also provide a little nausea relief. Popsicles, mints and gum may, too.

8. Stay positive

Sometimes our fears are worse than the reality, and each day of treatment can surprise you. Seek out the positives in your day – small and insignificant as they might seem – to keep your spirits lifted.

9. Prepare for possible hair loss

Most cancer patients who undergo chemotherapy experience hair loss, usually starting around seven to 21 days after the first treatment. For some, hair falls out gradually, while others wake up with big clumps on their pillow. But whether you lose your hair depends on the type and dosage of chemotherapy you’re receiving. Talk to your doctor about what to expect before starting treatment, then make plans for what you’ll do if and when you lose your hair. You might consider cutting your hair short or shaving your head once you start losing your hair, for instance, or decide to try out scarves, wigs, turbans or hats.

10. Remember that everyone’s experiences with chemotherapy is different

You’ll get lots of good advice, your experience with chemotherapy won’t necessarily be the same as that of another patient. Some people may want to stay in bed for days after chemotherapy, while others can go about their normal routine within a few days. And some patients lose their hair quickly, while others keep their hair longer – or don’t lose it at all.

So, go easy on yourself, pay attention to your side effects and share your questions and concerns with your care team.

Radiation Therapy Side Effects

Radiation not only kills or slows the growth of cancer cells, it can also affect nearby healthy cells. Damage to healthy cells can cause side effects.

Many people who get radiation therapy have fatigue. Fatigue is feeling exhausted and worn out. It can happen all at once or come on slowly. People feel fatigue in different ways and you may feel more or less fatigue than someone else who is getting the same amount of radiation therapy to the same part of the body

Why brain tumor treatment has you feeling more tired than you’ve ever felt, and steps you can take

Fatigue is the most common side effect of brain tumor treatment. All the major forms of cancer treatment, including chemotherapy, radiation, and even surgery recovery can cause fatigue.

Fatigue is more than simple tiredness. It is a widely-recognized medical condition, marked by extreme lack of energy, which can cause inability to function in daily life. It may be acute – lasting a short time in connection with a direct cause, or chronic — becoming a long-term fact of life for someone affected.

According to the NIH, fatigue related to cancer is different than what healthy people feel. Healthy people’s fatigue is generally relieved by sleep and rest. But for someone with a brain tumor, especially if they’re undergoing treatment, it is normal to experience some fatigue all the time, and for it to become very serious from a light amount of activity.

Even compared with other cancers, brain tumors can lead to especially severe cases of fatigue. Dr. David Cachia of the Medical University of South Carolina told Cancer Network that one study found 96% of patients with high-grade gliomas to experience moderate to severe fatigue. It’s not limited to the worst brain tumors either. Another study found that 39% of patients with lower-grade gliomas, interviewed more than 3 years after finishing treatment, still reported bouts of severe fatigue.
