The signs or symptoms of childhood non-Hodgkin lymphoma (NHL) may vary depending on where the cancer is in the body. Other health conditions can cause the same symptoms as childhood NHL.
The most common symptom of childhood NHL is swollen, or enlarged, lymph nodes in the neck, above the collarbone, in the chest (mediastinal mass) causing breathing problems, in the abdomen or in the groin. The enlarged lymph nodes are usually painless. Some children may have abdominal pain related to swollen lymph nodes in or near their bowels.
Sometimes NHL can cause generalized symptoms, or systemic, symptoms. This group of symptoms is referred to as B symptoms. They include fever, night sweats and weight loss. The fever usually has no obvious cause. The child’s temperature may be high for several days, or it may switch between normal and below normal for days or weeks. The night sweats are so heavy that the child’s bedding or clothes are wet and need to be changed. Weight loss is of at least 10% of body weight over 6 months.
