I have a mole on my cheek that's been there my whole life. Yesterday it was sore and hard. Today I squeezed around it and white stuff came out. Normal?

No. Any changes in a mole need to be investigated. Please see a doctor to ascertain if the lesion needs to be excised and tissue sent to a pathologist for examination.
Common. Often gland cells will become plugged which traps the glandular secretions over time. These will enlarge and need to be squeezed or lanced.
