Radiation Therapy for Brain Tumors: How It Works, When It's Used, and What to Expect
“They Couldn’t Remove All of It—But Radiation Helped
Stop It.”
Healthcare International is Transforming Radiation
Therapy for Brain Tumour
Not every brain tumor can be removed with surgery.
And sometimes, even after successful surgery, a few cancer cells may still
remain. That’s where radiation therapy steps in—precisely, powerfully,
and non-invasively.
At Healthcare International (HCI), we offer cutting-edge
radiation options that treat brain tumors without cutting into the brain—while
protecting memory, vision, speech, and quality of life.
This blog helps you understand:
·
When is radiation needed?
·
What types of radiation are available?
·
What’s the treatment process like?
·
What are the side effects and success rates?
Let’s walk through the answers together.
When Is Radiation Therapy Used for Brain Tumors?
Radiation may be recommended:
- After
surgery, to kill remaining tumor cells
- As
a primary treatment, when surgery isn’t possible
- For
recurrent tumors, to slow or stop growth
- To
treat multiple brain metastases
- For
benign tumors like acoustic neuroma or meningioma when they grow or
press on key structures
“Radiation is often a second step after surgery—but
sometimes, it’s the first and best choice.”
— Dr. Rakesh Jalali, Radiation Oncologist, HCI Network
Types of Radiation Therapy at HCI
1. External Beam Radiation Therapy (EBRT)
- Most
common type
- High-energy
X-rays targeted at the tumor over multiple sessions
- Delivered
via Linear Accelerator (LINAC)
- Painless,
non-invasive, daily sessions for 2–6 weeks
2. Stereotactic Radiosurgery (SRS) – e.g., CyberKnife
- Delivers
very high doses of focused radiation in 1–5 sessions
- Ideal
for small, well-defined tumors
- Pinpoint
accuracy to spare healthy tissue
- No
incision, no hospital stay
At HCI, we use CyberKnife SRS for:
- Brain
metastases
- Meningiomas
- Arteriovenous
malformations
- Acoustic
neuromas
- Recurrent
gliomas
3. Intensity-Modulated Radiation Therapy (IMRT)
- Advanced
shaping of the radiation beam
- Adapts
dose to tumor’s shape & size
- Protects
nearby healthy brain tissue (e.g., optic nerves)
4. Proton Therapy (via referral/partner centers)
- Uses
proton particles instead of X-rays
- Stops
radiation exactly at the tumor
- Fewer
long-term effects, especially in children
What Is the Treatment Process?
- Planning
Session (Simulation)
- You’ll
undergo a planning CT or MRI
- A
custom mask will be created to keep your head still during treatment
- Doctors
map the tumor and surrounding critical brain areas
- Treatment
Delivery
- Sessions
last 15–45 minutes
- Most
treatments are given Monday to Friday for several weeks (or as few
as 1–5 sessions for SRS)
- You’re
awake and can return home afterward
- Follow-Up
Imaging
- MRI
or PET scans monitor response
- Adjustments
made as needed
Side Effects of Brain Radiation
Radiation is targeted, but some side effects can
occur. These may include:
Short-term (during or after treatment):
- Fatigue
- Mild
headache
- Scalp
irritation or hair loss in treated area
- Temporary
memory lapses
- Nausea
(less common with antiemetics)
Long-term (in some cases):
- Cognitive
slowing
- Hormone
changes (if pituitary area is irradiated)
- Risk
of radiation necrosis (rare but manageable)
“We now combine radiation with neuroprotection strategies
like hippocampal-sparing IMRT and smart dosing.”
— Neuro-Oncologist, HCI
Success Rates and Outcomes
·
Glioblastoma: Radiation + chemo adds months
to survival and improves quality of life
·
Low-grade gliomas: Long-term control
possible
·
Brain metastases: SRS can control or
shrink tumors in 70–90% of cases
·
Benign tumors: SRS often stabilizes or
shrinks growth without surgery

Patient Experience with Healthcare International:
Chinwe, a 52-year-old from Nigeria, learned after surgery
that not all of her brain tumor could be removed. The fear of recurrence
weighed heavily on her family. At Healthcare International, she began advanced
radiation therapy, which controlled the remaining tumor cells. “Radiation
gave me a second chance—slowing down the disease and giving me back my
strength,” Chinwe shared with gratitude.
Radiation therapy is proof that you can fight brain
tumors without a scalpel.
And with today’s advanced technology, it’s more targeted,
comfortable, and effective than ever before.
