Low potassium, known as hypokalemia, is not commonly a direct indicator of cancer but can sometimes be linked to cancer or its treatments. Tumors in the adrenal glands or kidneys may cause hormone imbalances, reducing potassium levels. Chemotherapy can also lead to potassium loss due to side effects like vomiting or diarrhea. Digestive system cancers may affect nutrient absorption, contributing to the issue. However, hypokalemia is more frequently associated with other conditions, such as kidney problems or medication use.
