Dr. Msaouel, what is renal medullary carcinoma and how is it diagnosed?

Pavlos Msaouel, MD, PhD:
RMC is the acronym for a kidney cancer named Renal Medullary Carcinoma. Renal Medullary Carcinoma or RMC is one of the deadliest kidney cancers, and it predominantly afflicts young people mainly of African descent that carry the sickle cell trait or sickle cell disease.

Pavlos Msaouel, MD, PhD:
It is often diagnosed after patients start developing symptoms, and those symptoms can be blood in the urine -- the medical term is hematuria -- or they may have pain in their flanks on their side where the kidneys would be, on the right side or on the left side.

Pavlos Msaouel, MD, PhD:
Interestingly RMC mainly happens on the right kidney, so about 75% of all RMC cases will happen in the right kidney. And unfortunately, in the vast majority of cases when it does present, it will be what we call stage 4 -- meaning metastatic -- meaning it will have spread to other organs.
