2. Deficiency in immune system and infections can cause NHL
Although the exact causes of Non-Hodgkin lymphoma are yet to be known, most doctors believe that a deficiency in the immune system is the primary cause of this ailment. Immune system is usually deficient if the individual does not get necessary nutrients or proteins. At the same time, people diagnosed with HIV or others taking immune-suppresants are also likely to have a weakened immune system.
The deficiency is also observed in people who take medication after an organ transplant or take drugs to treat HIV. Individuals with inherent immunity issues like rheumatoid arthritis or even celiac disease might also be diagnosed with this ailment. Infections like HLTV-1, Helicobacter Pylori, human herpesvirus and the Epstein Barr virus can also cause Non-Hodgkin Lymphoma.
According to most medical professionals, the DNA changes that happen as a result of this ailment are usually acquired after the time of birth. They are not genetically transferred. The acquired changes can be an effect of being exposed to radiation and cancer causing chemicals. But there are also several situations when these changes do not happen due to any specific reason. The disease is usually observed among the elderly people. The risks of the ailment increase as we age.
