My 10 year son has swollen groin lymph node

Your son's doctor is not speculating on a possible cause of the swelling since he at this point does not know the source. Even an oncolgost could not know.

Childhood cancers are extremely rare, so do not jump to worst-possible conclusions. The doctor sounds thorough; most would not probably even be ordering an ultrasound at this point.  If anything looks suspicious to a radiologist, a CT would likely be next, and perhaps a biopsy.

Utrasound and CT are totally painless, and biopsy, depending on type, is usually close to painless also.  Share the blood panel results if you wish. Kids sense anxiety in parents, so please for his sake and yours, proceed calmly and quietly.

Thank you for responding. His

Thank you for responding. His blood work was normal so we have an ultrasound set up in 2 weeks. I don't know if it's good or bad that his blood work was normal.

Yes, I would think it good that his blood panel was normal.  But I understand your point: Does 'normal' rule out an infection of some sort.  The prior use of antibiotics likely did that already, but some infections are resistant. And the WBC does not test for a multitude of autoimmune problems.

So we just still do not know at this point.  The ultrasound will be a huge step forward toward diagnosis. But a biopsy may well be required.  But be aware that a week here, two weeks there investigating Lymphoma is almost always irrelevant; it virtually never moves fast enough for the dalays to cause problems. And most Lymphomas (if it is such) are about as treatable at late stages as they are at incipient stages.  This is a characteristic that makes Lymphoma diagnosis and treatment very different than many organ cancers.  I had massive involvemnt in every corner of my body, but it was about 2.5 months between my diagnosis and my first treatment. I asked the oncologist about this and he told me that it was absolutely irrelevant and not a cause for concern.

Remain calm and optimistic.  While difficult, the waiting is not making things worse for him,
