Children can and do get some kinds of kidney cancers, and they are treated with chemotherapy and surgery.
However, this chemotherapy is not oral; it is IV and must be given in the cancer center or hospital.
I do have a few patients now attending school while being treated, but they do miss at least a half-day once a week to come in for chemo, and they also are pulled if their counts are low, because this time of year, schools are not safe places for immunocompromised people.
EDIT: Lo, some are known as kidney cancers and some are not.
The most common kind of childhood cancer affecting the kidney is Wilms Tumor, which is also known as nephroblastoma.
But kids can get other kinds of kidney cancer (much less frequently)- I've known children with clear cell sarcoma of the kidney, and even more rare would be a really horrible kidney cancer called renal medullary carcinoma.
With CCS & renal medullary, the kids themselves and the families usually refer to it as kidney/renal cancer.
But with Wilms Tumor, the proper name is usually used.
Surgery is nearly always the first thing to do, but all three of these cancers are also treated with chemotherapy.
Very early stage WT might not need chemo, but all of the children I've known with it have required chemo.
Even with needing chemo, though, it's definitely not oral chemo.
It's IV chemo, given in clinic or inpatient, and every single child I've known to have any of these kidney cancers has lost their hair due to the powerful chemo.
Regarding the terminology used, one thing I've learned is that no matter how many times we say the proper terminology, there are always going to be some families who just don't get it.
It can be a little frustrating, but I see it happen daily, whether it's about the proper diagnostic term, a procedure, etc
