Genetic counselling for kidney cancer — what actually happens in the appointment

It is a structured appointment, not a test. A clinician trained in inherited cancer risk goes through your family in detail, works out whether an inherited explanation is plausible, and explains what a genetic test could and could not tell you. Only then is it decided together whether testing is worth doing. At CION this is led in-house by medical oncology, so the same team that would arrange any monitoring afterwards is the team having the conversation with you. Nothing is sent to a laboratory, and no sample is taken, until you have understood the implications and agreed in writing.

Because an inherited-risk result is unlike most tests you have had. It does not change; it applies to every cell in your body; and it is partly a result about your parents, your brothers and sisters, and your children as well as about you. Consent only means something if you understood all of that first. Counselling before the test also decides which test is the right one, because the family pattern points the laboratory at different genes. And it settles the question people forget to ask in advance: what would you actually do differently with each possible answer?

Most of it is your family history, drawn out properly rather than summarised. Expect to be asked about three generations on both sides: who was affected, by which cancer in which organ, at what age it was diagnosed, whether one kidney or both were involved, and whether anyone had features outside the kidney such as growths in the eye or nervous system, distinctive skin lumps, lung cysts or fibroids at a young age. Your own history, scans and any pathology reports are reviewed alongside it. The appointment ends with a clear recommendation and, if a test is offered, an explanation of every possible result.

No, and an appointment that ends without one has not been wasted. NCCN guidance reserves genetic risk evaluation for defined situations, such as kidney cancer diagnosed at a young age, tumours in both kidneys or more than one tumour, close relatives affected, or a syndrome already identified in the family. Where none of that applies, the honest and useful outcome is a clear explanation of why a test would not change anything, rather than a test performed to relieve anxiety. Many people leave with that answer and with the ordinary risk conversation they actually needed.

There are three kinds of answer. A disease-causing change may be found, which explains the pattern and opens up planned monitoring for you and testing for relatives who wish it. No change may be found, which is reassuring but not always final, because current panels do not cover every gene and some inherited risk still has no identified gene; if the family pattern is strong, monitoring may be advised anyway. Or a change may be found whose meaning is not yet known. That third result is not acted on as though it were harmful, and it can be reclassified later as evidence accumulates.

Your result is confidential and it is yours. Nobody is told without your permission. What counselling does is prepare you for the fact that a disease-causing result is genuinely useful to your relatives, because it lets them ask for the single specific test rather than a broad one, and lets those who carry it move to planned monitoring instead of waiting for symptoms. Who you tell, when, and with how much help from the team is your decision, and the counselling session is the place to plan it rather than something to improvise afterwards.
