Detroit resident Merrissa Hoffman had always wanted to donate blood, so when a friend mentioned that she had an appointment, Merrissa decided to go along and donate too.
Everything went well with the donation, but a couple of days later, Merrissa got a letter from the American Red Cross telling her there was something “abnormal” with her blood.
Merrissa visited a doctor and discovered she has a serious type of blood cancer. Fortunately, it was caught early and she was able to begin treatment right away.
