7 CM ovarian cyst, ca-125 levels elevated (48), roma score & all blood tests good. Previously had nasopharyngeal cancer. Recurrence or endometrioma?

7 CM ovarian cyst, ca-125 levels elevated (48), roma score & all blood tests good. Previously had nasopharyngeal cancer. Recurrence or endometrioma?

Likely endometrioma: At your age, ovarian cancer would be exceedingly rare. Ca-125 levels can be elevated in young women for a variety of reasons that have nothing to do with cancer. Nasopharyngeal cancer and ovarian have no relation to each other. Your doctor should tell you what features or characteristics the ovarian cyst has, this will tell you what kind of cyst it is. Good luck! ...Read more

Ca125 (Definition)

Ca-125 (cancer antigen 125 or carbohydrate antigen 125) is a biomarker/tumor marker for ovarian cancer (etc); however, it is not sensitive or specific enough to use as a screening test. Also, a uk study showed that treating based on ca125 level did not improve outcomes. "125" comes from the 125th attempt to develop a marker. It was introduced by bast ...Read more

Could you please tell me if a ca125 blood test is high do I need tahbso?

Could you please tell me if a ca125 blood test is high do I need tahbso?

Not always.: If this test is high, it could mean endometrial cancer, fallopian tube cancer, lung cancer, breast cancer and gastrointestinal cancer. This can also indicate benign conditions, like endometriosis, other ovary disorders, and pregnancy, as well as any inflammatory condition in the abdiminal area. This is a big reason why it is used with other tests in evaluation and to follow treatment response. ...Read more

What is a good decrease in the ca-125 blood test numbers with chemo?

Depends: The Best decrease is to normal values, less than 25. A good respond to chemo basically will show normal values that will stay normal. Any elevation of ca 125 after chemo may signal recurrence. ...Read more

My ca 125 blood test result slightly elevated, with a different reading 3 times, what could cause this to happen?

My ca 125 blood test result slightly elevated, with a different reading 3 times, what could cause this to happen?

Many causes: The ca-125 blood test is very sensitive-- in many cases it is too sensitive. In certain cases, it can be a marker of certain types of cancer. But in other patients, a modestly elevated ca-125 is not alarming. Visit with your doctor to better understand the details of your case. ...Read more

Where do I get a ca-125 blood test if I have no insurance but worry about cancer?

Save your $$: This blood test is useful only in certain situations and is not accurate if you are trying to make a new cancer diagnosis. It can be high even if you don't have cancer, and it can be normal in some situations when you do have cancer. My advice is to save your money, and visit your doctor if you have a specific concern. ...Read more

Not long ago found out that many times blood test called 'ca125" can tell if you have cancer.is it true?

Not long ago found out that many times blood test called 'ca125" can tell if you have cancer.is it true?

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. ...Read more

I went to take a ca-125 blood test and the doctors office said it was normal that I had an 8.6, is that actually normal?

I went to take a ca-125 blood test and the doctors office said it was normal that I had an 8.6, is that actually normal?

CA 125 - Why check?: 8.6 sounds like a normal value for the cancer antigen 125 (ca125) laboratory test. However, why did you want to get it? It is not a screening test for ovarian cancer. It is an adjunctive test for measuring tumor response (ie, a tumor marker) for patients with known ovarian cancer. It isn't perfect even when we know someone has ovarian cancer. ...Read more

Can a woman have a normal ca125 blood test and still have ovarian cancer?

Can a woman have a normal ca125 blood test and still have ovarian cancer?

Ovarian cancer: Yes. Only 85% of ovarian cancers have an elevated ca 12 at presentation. Therefore, 15 of every 100 women with a diagnosis of ovarian cancer have a ca 125 within the normal range. Ca 125 is not a diagnostic test. But is used to follow the progress of chemotherapy. ...Read more

I just received my blood test results which showed a ca-125 reading of 35. The blood test results showed hyper chromic microcytic anaemia.

Benign: A Ca 125 of 35 was found to be a useful cutoff point, with 99% of healthy women having values less than 35. Levels above 35 units are certainly seen in healthy women, but beyond the cutoff point of 35, the higher the value, the more likely there is trouble. With ovarian cancer, the levels measure in hundreds. Depends on what you are looking for. Repeat the test. You probably need some iron tabs. ...Read more

Does a ca125 blood test check for cancers other than ovarian cancer?

Can you diagnose whether someone has PID based on blood test, such as ESR, CRP, and CA125? Do they always rise without exception when someone has PID?

Can you diagnose whether someone has PID based on blood test, such as ESR, CRP, and CA125? Do they always rise without exception when someone has PID?

Need more info: There are no blood tests specific for PID. The diagnosis is base on lab test results, pelvic examination and may be imaging studies. It would be prudent to consult a gynecologist.
For good health — Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex.
Get HPV vaccine. ...Read more

I had uterine cancer. I had a partial hystroctromy at 24. My blood work came back with high amounts of CA 125. What typically are the next steps?

Work up: Two assumptions. Partial hysterectomy was adequate to Nall endometrial Ca. Also, at your age ovarys were left behind. Ca125 is not a diagnostic marker intermittently elevated in ovarian Ca, liver disease and other neoplasms. It can only be used for monitoring known disease. Now work up with CAT scan of abdomen necessary and biopsies to be taken if any lesion seen. ...Read more

Why is the ca-125 blood test for ovarian cancer not part of a yearly checkup?

Not beneficial: The ca125 test is not used for screening for ovarian cancer because it does not work in the general female population. The ca125 can be abnormal in situations without any cancer and most importantly using this test does not save any lives like in the case of maamograms for breast cancer. ...Read more

Is CA-125 100% accurate? I had yearly blood work done and my result are 40 U/ml. Could i have cancer? I was on my menstrual cycle when test was done.

Not accurate: Curious as to why a CA-125 level was drawn, since it's not a recommended routine test. There are many reasons why a result may be slightly elevated, including ovulation and menstruation. It's best to discuss these results with your doctor. ...Read more

On avastin (bevacizumab) for ov cancer. Could there be a spike in ca125 because tumors are shrinking/dying and spilling their content into blood stream?

Yes, it is possible: Ca 125 is a tumor marker which helps to make decisions about response or lack of it. But it takes 2-3 serial values to decide if the tumor is getting better or worse; one reading does not help as it can be rising both from tumor getting worse or getting smaller and releasing tumor chemicals, which is what ca 125 is. It takes 2-3 mos to be able to get a clear picture. Also, watch other tumor aspects. ...Read more

When your gyn checks you for an ovarian cyst and then asks you to take a blood test for ca-125. Is that a bad sign?

When your gyn checks you for an ovarian cyst and then asks you to take a blood test for ca-125. Is that a bad sign?

CA 125 - Why check?: Cancer antigen 125 (ca-125) is not a screening test for ovarian cancer. It is an adjunctive test for measuring tumor response (ie, a tumor marker) for pts w/ known ovarian cancer. It isn't perfect even when we know someone has ovarian cancer. In the appropriate clinical setting -- eg an abnormal ovary on imaging it might help determine if a mass is benign or malignant, but again is not perfect. ...Read more

Is the blood test called ca 125 to check the uterus for cancer, a good test?

No: It is not. It is often used as such but: a hint of oca requires careful investigation, often surgery. Ca-125 gives many "false positives" so some surgeries would have been unnecessary. This would be ok with those who had oca, but perhaps not with those who did not. Ca-125 also gives "false negatives". This is worse, as the reassurance was misleading! Pelvic sonography is a better tool. ...Read more
