Hello Beatrice and thanks for posting, 

I am sorry to learn about your mum's cancer coming back and that you have an ongoing health concern.

I'm afraid I can't say what is the matter so I am not in a position to be able to properly reassure you, do speak to your GP about this and find out what they think. 

I am not sure what is going on with the lump, but a high platelet count can occur for several reasons and may have nothing to do with cancer. I think infections, inflammation and tissue damage are probably the most common causes. It could have something to do with cancer as well, but this may not be at all likely. I think it is easy to imagine the worst especially when cancer is in the family and you have a lot of first hand experience of it.  Please don't assume anything for now and ask your GP what they think. There well be other things perhaps from the blood tests, that will them an idea of what this means. 

Give us a call if you want to talk anything over. The number to call is Freephone 0808 800 4040 and we are around from 9 till 5, Monday to Friday.

Take care,

Thank you Julia, I have an abdo scan for this lump, (it feels like a 10p size pea lump above bone) and another blood test on Monday, if the platelet count is still high then they will look at why, including possible cancers. 

One of my markers was raised in addition to the high platelet level, had the bloods done last Friday and told to come in to discuss with GP.

Next week I will know more


Re my mum, oncology will call me Monday re her treatment plan as it had been slightly delyed as Consultants were changed....

My anxiety is very high, father in law in ICU, will know tommorrow re status (cardiac arrest)... life has thrown everything in a few weeks.. my hubby is with his dad at the other end of the UK so I am pushing on here

Hi just to update you, my platelet level is still high although less than is was (I have been taking aspirin) also my CA125 is raised, I have an urgent referral to gyn and the abdo US on 1st.

My anxiety is very high as I read up on the link beteeen CA125 and high platelets, I am a nurse so tried to find quality research. 


Mum's treatment starts on the 26th and father in law has now passed away.


Please can you tell me anything Julia, the link between CA125 and high platelets. I have also had a cough for around a week now I am worried.

Hello and thank you for getting back to us. I am sorry to learn that your platelet count is still high.

I must admit that I was not aware of a specific link between a high CA125 blood test result and a high platelet count (thrombocytosis ). Although I know that studies have suggested that if some one has a persistently high platelet count, they perhaps should be checked for cancer, as the risk is a little higher. This may sound frightening, but most people with high platelets won't have cancer.

But thrombocytosis can occur in a number of different cancers and is not specific to ovarian cancer.  It can also occur in many other situations and so there is rarely a link. Often the cause of thrombocytosis is unknown (idiopathic).  I cannot really find much in the way of information specifically about high CA125 and thrombocytosis other than studies that suggest that they can exist side by side. But they did not really say much more. Also, when someone has ovarian cancer as it responds to treatment the CA125 goes down and if thrombocytosis is present, this also seems to improve.

Waiting for tests investigations and the results can be very stressful and so your worries are understandable. But I don't think that any information that I can give you will answer questions about your situation and tell you what is wrong. In fact I fear that I may have unnecessarily contributed to your worries, by answering your question and I do hope that this is not the case. I would imagine that July 1st must seem a long way away. I do hope that you have some answers soon.

All the best,
