In brief: No

Ca 125 is a tumor marker which is frequently associated with ovarian cancer.
The " Ca" refers to carbohydrate antigen which has little to do with cancer except when it is known that ovarian cancer is present. At that time the test can be used, for "monitoring" the response to treatment, but not for making the diagnosis. One of the frequent causes of an elevated Ca125 is alcoholic cirrhosis.
