20 Unexpected Signs and Symptoms of Lung Cancer

3. Weight loss

Weight loss for unknown reasons is often associated with cancer because tumors consume energy. When you notice a sudden weight loss, you need to pay attention before it's too late.

4. Body and bone pain

Unlike any other normal pain, you can't feel pain in your lungs as there are no nerve endings there. However, if the tumor has spread, you may suffer from pain in other body parts, such as your shoulders, ribs, or back.

5. High calcium levels

Lung cancer disrupts the balance of minerals in the body. The higher levels of calcium in your blood (hypercalcemia) may cause extreme thirst and frequent urination. If you have these symptoms, see your doctor.
