Is this ovarian cancer?

I am 42 and have just had 3 positive urine tests for pregnancy but my doc did a blood test which came back negative. Now i know that hcg hormone can be a marker for ovarian cancer and i have convinced myself that is what is wrong. I have no other symptoms though. would the hcg levels be high in blood aswell a urine if it was ovarian cancer. My doc is very laid back about it all and just thinks i am fretting. I have another blood test next week. I am so confused but have convinced myself its serious. Would point out i have missed my last period aswell. Everyone is telling me it wont be cancer but my brain is going into overdrive, i have been researching symptoms survival rates etc.

If you have convinced yourself you have ovarian cancer you are fretting. I'm not a doctor, but I see no reason to come to this conclusion.
There are no blood tests that can diagnose cancer as someone else has suggested. Although hCG can be elevated in germ cell ovarian cancers it is not for other types. There are several things that can cause a false positive pregnancy test. Although blood tests are more accurate it doesn鈥檛 mean they are more sensitive to hCG and varies from lab to lab. It makes no sense to pick a diagnosis and see if your symptoms fit. A diagnosis is made by the patient鈥檚 symptoms and the findings of diagnostic tests.
Ask plenty of questions and keep an open mind, but let your doctor be the doctor. If you are not comfortable with his findings get a second opinion.

Here is a site with some good information on Cancer

HCG levels can peak up during the Menopause, some women will start as early as 42.
If you are worried about ovarian cancer have a talk with your doctor. I am sure that they will do tests to get to the root of this.

Try to be brave. Surely you know that nobody on here can answer that question for you better than the doctor who told you to stop fretting.

the blood test for pregnancy is more accurate than a urine test. stress can make a period late or missed completely. if you feel that your doctor is being to laid back about all this then find another gyn and get a second opinion. there is a blood test that can be done for cancer. i had it done last year right before i had an emergency D & C. it showed negative. six weeks after the surgery i went back for another ultrasound and they found that i had over 20 cysts and tumours on both ovaries. one showing real thick. i wound up having both ovaries removed just to be on the safe side. i was lucky. there was no cancer on my ovaries. i am 53 years young. i hit menopause 5 years ago. the original surgery was because i started hemorrhaging real bad. that was why i had the cancer blood test done. like me you are going to be fine. i worried real bad while all this was going on and worried my family
all for nothing. set your mind at ease and as i said at the beginning if you are that concerned get a second opinion.
