If a person has cancer on one of their kidneys, do they have to still have hemodialysis once the cancer kidney is removed.

It depends on the functional ability of the remaining nephrotic tissue. If nephrectomy was performed on one kidney due to cancer, the other kidney may or may not be affected. If the remaining kidney is able to filter the blood and concentrate urine, HD (hemodialysis,ultrafiltration) may not be necessary. If however, the remaining kidney has hypertrophied trying to compensate for the cancerous kidney, then HD may still be needed to remove waste products from the blood.

Frequently, bilateral body structures will try to compensate for a damaged or diseased mirror organ. Eye injuries are good examples. If you injure one eye and have to rest it (wear an eye patch), the bilateral eye will compensate for the lack of vision. After the injured eye heals, the other eye (the one that was compensating) may now be strained or damaged because it was compensating.

It depends on the type of cancer.  I was diagnosed with leiomyosarcoma, lost my left kidney, but my other kidney is fine and I do not take any medication nor do dialysis.
