Tumour lysis syndrome
Some people having treatment for cancer can develop Tumour Lysis Syndrome (TLS), which results from the fast breakdown of cancer cells especially during the first couple of weeks of treatment. As the cancer cells are destroyed, they break open and the content of the cancer cell (uric acid, potassium, phosphorus) gets into the blood. This can lead to changes in kidney function, sudden kidney failure or even death.
If you do not have any heart or kidney problems, keep your fluids up by drinking at least 8 to 10 glasses of fluid daily. It is also important for you to keep your scheduled appointments for blood tests.
