Why is my birthmark growing? I am 45 years old.

This is normal for some kinds of birthmarks - part of aging. But, you should get it checked by a board certified Dermatologist to make sure it is not a new skin cancer arising in your birthmark or that your birthmark really is a skin cancer now. I have seen this phenomenon.
