Any good easy blood test to screen for ovarian cancer yet?

No. Some may offer a ca-125 blood test as a screening for ovarian cancer. Unfortunately, while ca-125 is found in 80-90% of ovarian cancer patients, it is not very specific (meaning it is elevated in a number of conditions) and is not found in early cancers. It is better used as a method of following cancer treatment and progression, once it is diagnosed.
Not yet. The usual markers for cancer are useful for measuring the progress of tumors, but not of much use as screening tools.
Unfortunately No. Until now, there is no good way that we can use to screen ovarian cancer unfortunately, ..Not a blood work, not an imaging study- nothing is good and reliable enough to screen ovarian cancer. Please f/u woth your gynecologist regularly.
