How does EBV cause lymphoma?
Some occur as rare accidents of virus persistence in the B lymphoid system, while others arise as a result of viral entry into unnatural target cells. The early finding that EBV is a potent B-cell growth transforming agent hinted at a simple oncogenic mechanism by which this virus could promote lymphomagenesis.
How does EBV cause non Hodgkin’s lymphoma?
EBV’s Connection to NHL
People age 65 years and older who had EBV at one time are at a higher risk for developing B-cell NHL because of the way the immune system ages over time. An EBV infection reprograms or hijacks B cells to become cancerous.
Can EBV lead to lymphoma?
The Epstein–Barr virus (EBV) is linked to various B-cell lymphomas, including Burkitt lymphoma (BL), classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL) at frequencies ranging, by routine techniques, from 5 to 10% of cases in DLBCL to >95% in endemic BL.

How do u get non-Hodgkin’s lymphoma?
Non-Hodgkin lymphoma is caused by a change (mutation) in the DNA of a type of white blood cell called lymphocytes, although the exact reason why this happens isn’t known. DNA gives cells a basic set of instructions, such as when to grow and reproduce.

Can lymphoma be misdiagnosed as EBV?
In the case of atypical presentation, lymph node and tonsillar biopsies are required to rule out lymphoma [3,4]. However, biopsies can lead to misdiagnosis, as acute EBV in lymphoid tissue can mimic both Hodgkin’s and non-Hodgkin’s lymphoma (NHL) resulting in inappropriate diagnosis and treatment [2,5].
What does positive Epstein-Barr test mean?
If someone is positive for VCA-IgM antibodies, then it is likely that the person has an EBV infection and it may be early in the course of the illness. If the individual also has symptoms associated with mono, then it is most likely that the person will be diagnosed with mono, even if the mono test was negative.
What is the prognosis for Hodgkin’s lymphoma?
The 5-year survival rate for all people with Hodgkin lymphoma is 87%. If the cancer is found in its earliest stages, the 5-year survival rate is 91%. If the cancer spreads regionally, the 5-year survival rate is 94%. If the cancer has spread to different parts of the body, the 5-year survival rate is 81%.
