There's no strict upper age limit for a bone marrow transplant, as eligibility hinges more on overall health, fitness, and disease status than age alone, though many centers traditionally consider patients over 70 as higher risk; however, advanced therapies and better supportive care mean many older adults (even into their 80s) are candidates, with evaluations focusing on individual fitness, not just the number on a birth certificate. Younger patients have fewer health issues, making them generally more eligible, but healthy older adults with few co-morbidities can be excellent candidates.
Donors over 70 years of age are no longer isolated or exceptional cases. They may still be considered eligible for donation but many of them, based on the older age and their medical history, may no longer fully qualify as 'healthy' or 'normal'.
Myth: Donation is very painful.
For a bone marrow donation, you experience no pain before or during the procedure, but you may feel sore or achy for a few days afterward.
The transplant
The stem cells will be passed slowly into your body through the central line. This process often takes around a couple of hours. The transplant will not be painful and you'll be awake throughout.
With increasing time from BMT, nonrelapse-related mortality becomes the leading cause of death, and continues to increase with time after BMT. The major causes of nonrelapse mortality include infection (with or without chronic graft-versus-host disease), subsequent neoplasms, and cardiopulmonary compromise.
Medical conditions that disqualify potential donors include: HIV/AIDs. Severe arthritis such as rheumatoid arthritis. Autoimmune diseases that affect your whole body.
Engraftment and going home after bone marrow transplant
Every patient's situation is unique, but you can expect to spend 30 to 60 days in the hospital or at the outpatient clinic for your transplant. The goal of BMT is for the donated cells to enter your bone marrow and start making new cells.
Blood donation age limits vary by country, but generally, you must be at least 17 or 18 years old, with first-time donors often having a maximum age (like 75 in Australia, or 65 in the UK) while regular donors can continue past that age if they remain healthy. Key requirements include being in good health, meeting weight criteria (around 50kg/110lbs), and having no recent illnesses or certain risky behaviors, with specific rules for different donation types like plasma.
For those aged between 70 and 79:
around 5 out of 100 (around 5%) will survive their leukaemia for 5 years or more after diagnosis.
Today, we use medications that stimulate the stem cells to move out of the bone marrow and into the bloodstream, where they can be collected more easily. Stem cell transplant is very similar to bone marrow transplant, except the stem cells are harvested from the patient's bloodstream rather than from the bone marrow.
Patients will be isolated for 100 days after a bone marrow or stem cell transplant as the new immune system starts working, avoiding public spaces and crowds. Patients should also be very careful about having guests. Meeting people outdoors is considered safer than indoor get-togethers.

Golden blood is the rarest kind of blood known in the world. It's also called Rh null blood, and about 43 people have ever been reported to have it. "The name 'golden blood' can sound like this is blood that's somehow more pure or safe for transfusions,” Dr. Otrock shares.
The age limit on blood donations was raised from 65 to 70 in 1998. An age limit was put in place as a precautionary measure to ensure the safety of the donor, but recent evidence from other blood services has shown no harm to donors over the age of 70.
In most cases, though, there is no bone marrow transplant pain. The patient remains awake throughout the entire process, and it is not uncomfortable. In fact, the bone marrow transplant procedure is very similar to receiving blood or medication through an intravenous (IV) catheter or tube.
Because of this, many hospitals require that patients have a 24-hour caregiver for the first 3-6 months after BMT. A caregiver is often a patient's spouse or relative. However, some people don't have a healthy spouse or relative who can care for them for 3-6 months. They may need to rely on friends or others.
Preparing a Safe Home After a Bone Marrow Transplant
With age comes a small increase in the risk of side effects from anesthesia, and recent NMDP studies reveal that patients receiving marrow or blood cell transplants from older donors have a somewhat poorer survival rate.
In particular, adults between the ages of 18 to 35 are urgently needed because they're requested by transplant doctors most often. A patient's chance of finding a matched, available donor on the Be The Match Registry ranges from 29% to 79% depending on the patient's ethnic background.
Why donate? Research scientists use the cells from your donated bone marrow to develop and test medicines and treatments with the potential to change lives dramatically. Not only will you be helping to create the treatments and cures of tomorrow, you will receive $600+ to compensate for your time and effort.
Graft versus host disease (GvHD) with a donor transplant
If you have had a transplant from a relative or a matched unrelated donor, you are at risk of GvHD. This is because the donor stem cells contain immune cells from the donor. These cells can sometimes attack some of your own body cells.
Doctors usually say avoid going abroad for at least 6 months after a bone marrow or stem cell transplant. Most people need to have regular check ups. You might also need blood transfusions during this time. Once your blood counts have gone back to normal, you'll be able to travel.
For patients, this takes anywhere from one to three days; for donors, usually one to two days. In special cases that are identified by the transplant physician, stem cells are collected from the bone marrow, a one-hour procedure called marrow harvest, during which marrow is drawn from the patient/donor's hipbone.
There is no upper age limit for blood donation as long as you are well with no restrictions or limitations to your activities. Those younger than age 17 are almost always legal minors (not yet of the age of majority) who cannot give consent by themselves to donate blood.
