Those with lymphoma or leukemia are permanently deferred from donating blood (however, eligibility criteria for adult survivors of childhood leukemia who were diagnosed when they were 18 years old or younger may vary). All other types of cancer will be assessed at the time of donation, but 12 months must have passed since the last treatment and you must be considered cancer-free at the time of donation. ## Source - https://www.vitalant.org/eligibility Last verified: 2026-08-13.
