Shannon Tavarez has leukemia and will get an umbilical-cord blood transplant on Tuesday. It's used as an alternative to treat the disease when a perfect bone marrow match can't be found.

The actress was forced to quit the show in April. Cast members held a bone marrow donor registration drive for her last month.
