MY CANCER VACCINE JOURNEY – WEDNESDAY 4 NOVEMBER 2026
DAY FOUR – TAKING THE BRAKES OFF MY IMMUNE SYSTEM!
Today was another big milestone in my cancer journey.
My first dose of checkpoint inhibitor immunotherapy!
Today's treatment involved two medications — Ipilimumab and Nivolumab.
Now, these aren't medications routinely used together for my particular type of breast cancer, but they are being investigated in combination with personalised cancer vaccines.
And the science behind them is absolutely fascinating!
SO WHAT EXACTLY ARE CHECKPOINT INHIBITORS?
Our immune systems are incredibly clever. They have built-in checks and balances to prevent our immune cells from attacking healthy tissue.
Think of these as the brakes on your immune system.
Unfortunately, cancer can exploit these natural braking mechanisms to escape immune attack.
Checkpoint inhibitors work by blocking specific signals that restrain immune cells, potentially allowing them to respond more effectively against cancer.
SO HOW DOES THIS WORK WITH MY CANCER VACCINE?
My personalised cancer vaccine is designed to teach my immune system to recognise specific mutations found within my cancer.
The checkpoint inhibitors are intended to complement this process by reducing some of the signals that suppress immune activity.
In simple terms:
The Vaccine: Aims to teach my immune system what to recognise.
The Checkpoint Inhibitors: Aim to release some of the immune system's brakes, giving immune cells a better opportunity to respond.
The Goal: Encourage a stronger, more targeted immune response against my cancer.
It's important to understand that this combination is still experimental in my particular cancer setting. We don't yet know whether it will improve my outcome.
But understanding how these different approaches might work together is one of the most interesting parts of this journey.
OUR BODIES ARE EXTRAORDINARY!
One thing I never stop being amazed by is just how technically complicated the human body is.
Every second, our bodies are constantly adjusting, balancing, repairing and responding to what's happening around us.
When we're healthy, much of this happens without us even realising.
But when you're living with a disease such as cancer, the biological puzzle becomes incredibly complicated.
There is still so much we don't understand.
And with advances in molecular medicine, genetic testing, immunology and artificial intelligence, researchers are finding new ways to investigate cancer biology.
The more I learn, the more I realise how much there is still to discover!
MY TREATMENT IS ABOUT MORE THAN JUST THE VACCINE
My personalised vaccine is only one part of a much broader treatment programme.
Alongside my prescribed oncology medications and treatment here, I place a strong emphasis on supportive care at home.
For me, this includes:
Balanced nutrition, with attention to my individual health needs.
♀️ Regular movement and maintaining physical strength.
Good-quality sleep and recovery.
Supporting normal lymphatic function through appropriate movement and care.
Infrared sauna and hyperbaric oxygen sessions, where appropriate and medically cleared.
Working with practitioners to understand my cancer's molecular pathways and explore whether there are evidence-based opportunities to target them.
Supporting hydration, digestion and the body's normal liver and kidney functions.
Not all these approaches are proven to slow cancer or improve vaccine effectiveness, but I believe it's important to consider my overall health and quality of life while receiving cancer treatment.
The goal is to support my body while my medical team works to control the cancer.
SO HOW DID TODAY'S IMMUNOTHERAPY GO?
I won't pretend I wasn't nervous!
This was my first experience receiving checkpoint inhibitors, and I know these medications can cause significant side effects.
But thankfully, today's administration went smoothly.
A little tired, a little dizzy, but otherwise feeling pretty good!
First checkpoint inhibitor treatment — DONE!
Afterwards as a reward Coffee and Gluten Free, Dairy Free, Sugar Free Pistachio Pancakes. Some days you just need a reward to make things feel all worth while!
ONE THING I'VE LEARNED – IMMUNOTHERAPY REQUIRES RESPECT
Just because you feel fine immediately after treatment doesn't mean you can forget about potential side effects.
Checkpoint inhibitors can cause the immune system to attack healthy organs and tissues, sometimes days, weeks or even months after treatment.
The effects can occur with low doses too, which is why careful monitoring is essential.
My medical team has discussed the importance of recognising symptoms early and knowing when to seek medical attention.
I also make a point of paying close attention to what is normal for my body.
And whenever possible, I prefer to avoid introducing several unfamiliar treatments on the same day, so it is easier to recognise potential reactions.
Although, with immunotherapy, delayed effects can still make identifying the cause challenging.
Being proactive about treatment also means being proactive about safety.
WHY AM I SHARING ALL OF THIS?
Because I know firsthand how overwhelming cancer can be.
Seven years into my metastatic cancer journey, I have spent countless hours researching, asking questions, exploring options and trying to understand this incredibly complicated disease.
It is also why I created Boost IV Health & Wellness and why we are developing Lighthouse Health & Wellness Trust.
Through our Cancer Terrain and Cancer Concierge Programmes, we aim to help patients better understand their options, coordinate additional supportive care and navigate complex health information alongside their oncology teams.
Nobody should feel they have to figure everything out alone.
AND SO MY JOURNEY CONTINUES...
Another treatment completed. Another experience behind me. Another step forward.
I don't know what the coming weeks or months will bring.
But I do know that I will continue asking questions, learning, monitoring my health and making carefully considered decisions with my medical team.
I am not looking for miracles. I am looking for more time, more good days and more opportunities to LIVE.
Thank you to everyone following my journey. There is still so much more to share over the coming weeks!
