How informed are you?

It’s a fact, blood cancers and disorders affect Americans nationwide. A bone marrow transplant is often the best treatment for those suffering. Sadly, patients of color have a harder time of finding a match.

Every 3 minutes in the U.S., someone is diagnosed with a blood cancer. For many patients, a bone marrow transplant is the best chance at recovery. While 30% of patients can find a matching donor in their families, 70%—nearly 12,000 each year—must rely on a benevolent stranger to step up and donate.

Misinformation is the biggest challenge facing all potential bone marrow donors today.

Common blood cancers/disorders

Sickle Cell Disease

Sickle cell disease (SCD) is an inherited disease of hemoglobin, a molecule that carries oxygen within red blood cells. Patients with sickle cell disease have red blood cells containing abnormal hemoglobin, which causes the cells to become stiff and form a sickle or crescent shape.


Leukemia is a blood cancer that develops when normal blood cells change and grow uncontrollably. There are four main types named according to the cells affected (myeloblasts, lymphocytes) and whether the disease starts with mature or immature cells (chronic, acute).


Lymphoma is the name for a group of blood cancers that develop in the lymphatic system. The two main types are Hodgkin lymphoma (generally starts in blood and bone marrow) and non-Hodgkin lymphoma (generally starts in lymph node and lymphatic tissue.)


Because it is difficult for sickle shaped cells to pass through small blood vessels, the flow of blood is sometimes blocked, and oxygen does not reach nearby tissues. A bone marrow transplant is the only known cure for sickle cell disease. A well-matched donor is needed to have the best chance for a successful transplant.

What’s a way to help someone suffering from a blood cancer?

You can sign up as a potential bone marrow donor. So how does it work?


Swabbing is the test used to see if you are a bone marrow donor. We send you a cheek swab kit, you swab your cheeks and sent it back to us. Once we receive it, it goes to the lab for processing and you are put on standby until you are a match for a patient in need. You may not be called right away so make sure that you keep your information updated.


We will contact you once you are a match for a patient in need. We will reach out via phone call, text, and email. Please make sure that you keep your information updated, in case you move or change your email address. A patient's life may depend on you. Answer when you get the call you are a match for a patient in need. The doctor determines the best method of donation for you.


The most common form of bone marrow donation is Peripheral Blood Stem Cell (PBSC) Donation. This is the donation method used in 75% of cases. The second method is Bone Marrow Donation, this is the donation method used in about 25% of cases, generally when the patient is a child.


The most common form of bone marrow donation is Peripheral Blood Stem Cell (PBSC) Donation. This is the donation method used in 75% of cases. PBSC donation is a non-surgical, outpatient procedure that collects blood stem cells via the bloodstream. During the procedure, your blood is drawn through one arm and passed through a machine that filters out the blood stem cells. The remaining blood is returned to you through your other arm. To increase your blood stem cells prior to donation, you will receive daily injections of a synthetic protein called filgrastim on the four days leading up to and on the morning of the procedure. The actual donation can take from 4-8 hours over the course of 1-2 days.

Bone Marrow Donation This is the donation method used in about 25% of cases, generally when the patient is a child. It is a 1-2 hour surgical procedure performed under anesthesia, so you will be put asleep. Marrow cells are collected from the back of your hip bone using a syringe.

Only 4% - The challenge for Astrid to find a match.
While Astrid is battling a rare form of #leukemia, she worries about the future of her children, just like any loving mom: “The thought of not seeing my little boys grow up is unbearable to me.” .
Astrid is mixed race of Nigerian and European decent, and ancestry plays a big part of the matching process. Currently, donors from minority ethnic backgrounds make up 4% of the donor registry. We need to help change her chances of finding a match! We can save Astrid and other mixed race patients! Join her fight.

Katharina could not believe what was happening to her. .
“I had just moved out for college, it was the time after my exams at school, time to be free. At the beginning I thought that my incredible fatigue was just caused by all of this change. But at some point, even small things like riding my bicycle were strenuous, I even fainted multiple times very sudden. At the doctor, it was clear all at once that something wasn’t right, my blood cells were unbelievably low. The diagnosis came quickly, but I couldn’t really grasp what this meant. I thought “It’s not cancer, can’t be that bad.” But I learned quickly. I was pulled out of my life, was in the hospital 2-3 times a week and constantly needed transfusions to even survive until treatment began.
I got some kind of “mini chemo”, but relapsed after two years. I was desperate: My life had just begun once again very recently. So we started all over – and I needed a #bonemarrowtransplant. I was very lucky because my little brother was my match. But I also had mixed feelings: Happiness about the option but also worries if my brother would manage the surgery well. He did and I’m eternally grateful for his gift. Today, I’m quite well again – I still struggle with fatigue and need to take medicine, but I won’t complain at all. The transplant gave me my normal life back!
I am well aware that not all patients have the luxury of having a matching sibling. Because of this it’s incredibly important for me to show how easy it is to save someone else’s life. Most people don’t think about it, I didn’t do either until I got diagnosed. But perspective changes when you’re right in the middle, of course. I’m grateful for every single person signing up!” Please register today and let’s fight together to help save even more people.

After listening to a story on the @kiddnation show, Eryn was inspired to sign up as a potential #bonemarrowdonor 💉 . Last year @berrt.n.errn gave a patient a second chance at life. 
You are awesome Eryn! 💪

Bennett is home! Last year we featured Bennett, an eight year old boy diagnosed with myelodysplastic syndrome (MDS). In December, he found a matching donor and underwent a bone marrow transplant. Over the weekend, Bennett celebrated his 100 day post transplant, an important milestone in his recovery 🎉 🎈. #DKMS #DeleteBloodCancer #TeamBennett #fightbloodcancer #savelives #Hope #DoGood
