All volunteers responded to a form with questions about eating habits, body weight and lifestyle.

What is the difference between Hodgkin's lymphoma and non-Hodgkin's lymphoma?
"The only difference between these two types of lymphomas is that of Hodgkin's presenting reed-sternberg cells, while the second case does not. It seems little, but this small difference drastically changes the type of treatment to be used in the patient, "says hematologist Jane de Almeida Dobbin Head of Service
Who has cases in the family need to worry?

What are the chances of a cure?
While Hodgkin lymphomas have a cure chance of approximately 75%, the large number of types of non-Hodgkin's lymphomas makes the chances of cure vary greatly. "In addition, the chances of cure vary according to some other factors, such as age, anemia and number of affected lymph nodes, which are specific to each patient," the hematologist explains.
The chances of cure can range from zero, when lymphoma is indolent, up to approximately 90%, when it is classified as aggressive.
"When lymphoma is aggressive the chances of cure are greater. being of several decades of life and there are virtually no symptoms at the time of diagnosis, "says Jane Dobbin.
