Lung cancer itself does not directly cause acidosis. However, certain complications of lung cancer or its treatment can lead to acidosis. For example, if lung cancer spreads to the bones, it can cause hypercalcemia (high levels of calcium in the blood), which can lead to metabolic acidosis. Additionally, certain chemotherapy drugs used to treat lung cancer can cause metabolic acidosis as a side effect. It is important for individuals with lung cancer to be monitored closely by their healthcare team to prevent and manage any potential complications, including acidosis.
