endometriosis cancer being confirmed by Lab test

Hi I started bleeding in march and finally got into doctor on Monday May 22nd, doctor immediately after the Pap smear said I have endometriosis cancer, I did blood work on Tuesday a complete CBC, CA 125, Thyroid panal and this morning a new test showed up on my labatory pending list called a testosterone, free and total (MS). Can anyone tell me just what the testosterone test is about?
