What Are the Risks of Donating Stem Cells?

January 9, 2025

Thinking about becoming a stem cell donor? You might be wondering – what’s the catch? The good news is that it’s a pretty safe process, but like any medical procedure, there are a few things to be aware of. Let’s break it down in a way that’s easy to understand.

Is Stem Cell Donation Safe?

Yep! Stem cell donation has been done for decades and is considered really safe. It’s a crucial process for people with blood cancer, including Chronic Myeloid Leukaemia and other serious conditions. But, of course, no procedure is completely risk-free – so let’s talk about what to expect.

What Are the Risks of Peripheral Blood Stem Cell (PBSC) Donation?

PBSC donation is the most common way to donate stem cells – about 90% of donations happen this way. You’ll take a medication called G-CSF for a few days before donating to increase the number of stem cells in your blood. So, what are the possible side effects?

1. Side Effects From G-CSF

  • Some people feel a bit under the weather, with mild flu-like symptoms like muscle aches, headaches, or tiredness.
  • These usually disappear a day or two after donation. Many donors don’t feel anything at all.

2. Risks From The Donation Process

  • The donation process, called apheresis, is similar to giving plasma – you sit in a comfy chair while your blood is drawn, stem cells are filtered out, and the rest is returned to your body.
  • Some donors feel a little lightheaded or get a tingly sensation (caused by the anticoagulant used), but these effects wear off quickly and are monitored by medical staff.

What Are the Risks of Bone Marrow Donation?

Bone marrow donation is less common – only about 10% of donations are done this way. It involves taking stem cells directly from your bone marrow (usually from the hip bone) under general anaesthetic. Here’s what you should know:

1. Anaesthesia Risks

  • Since you’ll be under general anaesthesia, there’s a tiny risk of nausea, vomiting, or an allergic reaction – just like with any surgery.

2. Pain and Recovery

  • You might feel sore or stiff in your lower back or hips for a few days to a couple of weeks.
  • Some people feel tired for a little while afterward, but most recover quickly and are back to normal within a week or two.

3. Infection or Bleeding

  • There’s a very small chance of infection or bleeding at the collection site.
  • Doctors take loads of precautions to keep everything sterile, and any issues are treated quickly.

Long-Term Risks – Do Stem Cells Grow Back?

A big question people ask is – will my body replace the stem cells? The answer is YES!

1. PBSC Donation Recovery

  • Your body replenishes the donated stem cells within a few weeks.
  • Most donors feel completely back to normal within a day or two.

2. Bone Marrow Donation Recovery

  • Bone marrow regenerates fully within 4-6 weeks – but you’ll barely notice.
  • There’s no evidence that donating bone marrow has any long-term negative effects on your health.

Emotional Considerations

Beyond the physical stuff, some donors feel a mix of emotions throughout the process.

1. Feeling Nervous

  • It’s totally normal to feel a bit nervous before donating. Knowing what to expect can help calm those nerves.

2. Wondering About the Recipient and the Contact Process

  • Some donors feel emotionally connected to the patient they’re helping. In Australia, donor and recipient contact is managed carefully. Initially, donors can receive anonymous updates about their recipient’s progress through the registry. After a waiting period, and if both parties consent, direct contact may be possible through the donor registry. In Australia, this can occur after a two-year waiting period, provided both the donor and recipient consent to exchanging contact details.

There are support groups and medical staff who can help if you need to talk about it.

Why the Benefits Outweigh the Risks

Let’s be real – saving a life is worth a few mild side effects. For many patients with blood cancer, a stem cell transplant is their only hope. By donating, you could literally be the reason someone survives.

Final Call to Action

The risks of stem cell donation are minimal, but the impact is life-changing. For someone with blood cancer, a stem cell transplant could be their only chance at survival. If you’re aged 18-35, you have the opportunity to be that hope. Ready to step up and save a life? Join the Australian Stem Cell Registry today. It’s simple, free, and could save a life.
