New research indicates that heavy use of antibiotics during childhood increases the likelihood of developing non-Hodgkin's lymphoma (NHL), a cancer that affects the body's lymphatic system.
A "Striking" Association
Researchers looked at data from the Scandinavian Lymphoma Etiology study, which compared over 3,000 patients with NHL with a similar number of healthy patients. There was a "striking" association between antibiotic use and NHL for all subtypes of the disease, especially for those who had been given antibiotics more than 10 times as children.
A Cause, Or an Effect?
This could mean that the increasing use of antibiotics in the 20th century might also explain the rise in NHL cases. However, it is unknown whether antibiotic use caused the NHL, or if antibiotics are simply more likely to be taken by those prone to developing NHL.
Also True for NSAIDs
There was also an increased risk of NHL for heavy users of non-steroidal anti-inflammatory drugs (NSAIDs). This includes ibuprofen drugs such as Motrin and Advil.
