Matches are determined by HLA typing and there are thousands of HLA molecules in millions of combinations.
The process is like finding a needle in a haystack, but Peter is on a mission to improve the odds for himself and others like him.
In January of this year, I took 42. Unfortunately, according to my doctor, I can only have three or four birthdays left to celebrate.
In September 2016, my life was turned upside down by an unexpected diagnosis. I had just finished an Iron Man triathlon and was fitter than I had ever been.
Two days later, I found myself in the Countess of Chester at the Hospital with pneumonia, sepsis and legionnaires.
Four months later, I was diagnosed with multiple myeloma, a cancer of the blood, which was manageable but incurable.
I was later told that if I had done it over the next seven years, I would have done it right.
So many questions. Why me? What did I do to deserve this? Too many kebabs in uni? Mobile phones?
I found myself in a hot tub, hence my internally-negativity was carried to suck me in the center and far from the most stable of thought.
The idea of losing my life, when I had worked so hard for my family, made me as angry as it made him sad. I decided to find out what life could be like to accept it and live with cancer.
I learned that every 20 minutes someone in the world will have the same information as I do: a diagnosis of blood cancer.
I learned that one of two people will be diagnosed with cancer in their lifetime.
In reality, there was only one question, which required an honest, yet unpleasant, answer: Why not me?
You could go down in a spiral of self-pity and despair, and I can understand why some might do it. But why lose what life is I feel like this?
We can all choose to be a victim of circumstances, to wallow in self-pity and to play the passengers of the situation. Or we can take charge and make the decisions on our terms to get through it. It gives us power and empowerment rather than leaving them feeling helpless.
Myeloma has left my compromised immune system. Stem cells can be used to solve this problem. Mine does not work, but yours.
I need someone who is a genetic match to donate some of his stem cells, which can be transplanted into my blood.
I am now on a mission to find my perfect match. I started at From 10,000 Donors campaign and am more than proud to have broken my goal which has resulted in more than 45,000 people registering for charity blood cancer DKMS. Of these potential donors, 15 have been confirmed as matches.
There are approximately 30 million people on stem cells enrolling globally. Unfortunately, none is a match for me or thousands of other people like me.
In the UK, only 2% of the population has signed up for stem cell donation. DKMS is dedicated to the fight against blood cancer.
The charity has a growing registry of more than 680,000 donors, but we desperately need more if we are to find a match for everyone who needs it.
It’s just a numbers game.
Thank you for helping me hit the new target of 100,000 residents and sign up today: https://www.dkms.org.uk/en/register-now
