You may have more choices than you realize.
In Betsy's entry, Ms. Jessie Gruman writes "...you may have more choices than you realize", referring to prospective treatment options for any disease.
This is exactly what Betsy and I have been exhorting. You, the patient, may have more treatment options than suggested to you by the medical oncologist. The medical oncologist often does not speak of radioimmunotherapy (RIT) when outlining treatment options to the lymphoma patient.
Therefore, the patient has the responsibility to insist on a consultation with a physician who is an expert in RIT---a radiation oncologist or nuclear medicine physician.
