Having received the benefits of medical care, many cancer patients and survivors wish to give back in some way. Which gives rise to a common question: "Can I donate blood if I have had cancer?" The answer isn't a simple yes and no and varies depending upon the donation center, the type of cancer you have or had, how long it has been since you were treated, and in which country you live. But the answer to one thing is clear—if you have asked this question as a cancer survivor, those who are living with cancer today are grateful.

Why Wouldn't Someone With Cancer Be Able to Donate Blood?

Before discussing the guidelines for blood donation after cancer, it's important to discuss the reasons why donating may not be allowed or advisable.

  • For the donor – Many people with cancer can see clearly the importance of donating blood, but this may not always be a healthy option. In some cases, chemotherapy can damage bone marrow resulting in anemia even long after treatment. Donating blood also requires a healthy heart, and even the mild anemia created by donating blood could possibly harm those who have cardiac damage related to chemotherapy and radiation therapy.There may also be medical reasons other than cancer that would make donating blood unhealthy for your particular situation.
  • For the recipient of blood products – The risk of transmitting cancer by a blood transfusion is primarily a theoretical risk; there haven't been any reports of people getting cancer from a blood transfusion. But the fact that, in rare instances, cancer has been transmitted via organ transplants, has resulted in guidelines restricting adults who have had blood cell cancers, such as leukemia, from donating blood.

    Basic Blood Donation Eligibility Requirements

    The basic requirements for blood donation state that it is okay for an individual to donate whole blood every 56 days if the following guidelines are met:

    • Being at least 17 years of age (or age 16 with permission from a parent)
    • Being in general good health and feeling well
    • Weighing at least 110 pounds

    Further requirements include restrictions on some medications, the absence of HIV/AIDS, and a normal hemoglobin level among others.This site discusses the Red Cross eligibility requirements as well as a list of eligibility criteria by topic.

    When Blood Donation is Okay For People With Cancer (United States)

    It's important to note that eligibility to donate blood can vary depending upon the cancer center or blood donation organization. For people who have had cancer, the donation center may require a letter from your oncologist indicating that it is safe for you to donate blood. In general, cancer survivors can donate blood if:

    • You meet the basic criteria above.
    • It has been at least 12 months since the completion of cancer treatment, and you currently are cancer-free (have no evidence of disease - NED).This applies only to people with solid tumors; those who have had blood-related cancers (such as leukemia and lymphoma as an adult) may never donate blood. That said, some centers require 5 years, and others 10 years, after the completion of successful cancer treatment.
    • You are a childhood leukemia or lymphoma and it has been at least 10 years since being deemed cancer-free.
    • If you had a very early cancer in which surgery is curative (for example, ductal carcinoma in situ - DCIS).With these very early cancers, survivors can donate blood as soon as they are healed from surgery.

    When Blood Donation is Not Allowed for People With Cancer (United States)

    People with cancer are not eligible to donate blood:

    Outside the United States

    Not only do eligibility requirements vary among different organizations in the United States, but vary between countries.  A few examples follow:

    • Canada - Contact the Canadian Blood Services to discuss criteria.
    • In the U.K. - Guidelines from the United Kingdom Blood Transfusion and Tissue Transplantation Services state that cancer survivors may not donate blood. Exceptions include those people with basal cell skin cancer which has been completely removed and has healed, and those with precancerous cells - such as abnormal cervical cells - which has been treated and no abnormal cells remain.
    • Australia - According to the Australia Red Cross Blood Service survivors of solid tumors (but not blood-related cancers) may donate blood 5 years after cancer treatment is completed and remain cancer free.

    Desire to Give Back

    For those cancer survivors who are unable to donate blood, there are other ways to help people with cancer. Perhaps you wish to participate in a relay for life, or host a fundraiser for a friend with cancer. There are many cancer support groups in which people who are newly diagnosed find comfort in speaking with those who have gone through cancer treatment before them.

    If you still feel saddened about the need for blood, consider asking friends or co-workers to donate when you can't. Many friends of cancer survivors feel privileged to have a way to help, and this can be one way to help not only your friend but others in need.

    Will You Know if Your Donation Makes a Difference?

    For privacy reasons, donors will not be able to hear about patients who benefit from their donation. That said, the Red Cross states that every donation saves 3 lives.  And in Sweden, the county council will text you when your blood is used!
