Low white cell count post radiotherapy

I had my hysterectomy in Jan 22, and radio April-May 22. At my Dec 22 check up I mentioned to the oncologist that I was feeling a bit tired still, so she requested a repeat thyroid function test (I am already hypothyroid). My GP likes to get good value from blood tests so decided to also add in a full blood count and B12 check. Thyroid came back normal, B12 was borderline OK, but my white cell count was slightly low (below normal). A repeat full blood count after 6 weeks gave the same result. My GP was concerned it could be some kind of infection even though I had no symptoms.  I mentioned having had radio but he was a bit dismissive and said it was usually with chemo that that could happen. I then started taking a vitamin B complex supplement in case it would help. A second repeat 6 weeks after that showed a slight improvement, which was a relief, and a third repeat 6 weeks later (mid June) showed another slight improvement, almost normal. My B12 had improved too, I saw my oncologist last Friday for my check up, and told her about it, and she said that because the area covered by pelvic radiotherapy involves quite a lot of bone, and that means the bone marrow can be affected, resulting in lower white cell production. I’m almost back to normal now and not at all concerned, but I thought I’d mention it here as I’d not seen it mentioned here before.

    Hi  

    Thanks for this. Very interesting. I expected my bloods to be low after chemo but the oncologist said that they were about normal.

  • Hi, the GP’s initial reaction caused me a fair bit of anxiety and he was even talking of testing for Lyme disease, lupus and other things, and the mention of a referral to haematology made me worry a bit about blood cancer. Curious that he didn’t know about the connection with pelvic radio but I guess they can’t know everything! 

  • Hi Marmitefan59,

    Thanks for sharing. I had very low white blood cells after both chemo and after radiotherapy. I was told that the chemo attacks the bone marrow in your hip bones where it is made and that it is common to have bloods that come back low after pelvic radiotherapy for a similar reason. I was told it was going to take a few months after treatment finished for the blood cells to be getting back to normal as they are being affected quicker than the time it takes them to be made. 

    I had problems with neutropenia, haemoglobin levels and with magnesium. I was given supplements and a blood transfusion. At my last appointment I did ask whether it would be worth taking B12 because of peripheral neuropathy- I had heard that it helps with nerves- but was told it wouldn't harm me but wouldn't do much good. Instead I discussed taking a multi vitamin, multi mineral and calcium/vit D for bones. They said this was a good idea as the bones are affected by the radiotherapy.

  • Hi Jane, mine was mild neutropenia and mild lymphopenia. I already take a calcium supplement as I also have osteopenia and also take a vitamin/mineral supplement to support my thyroid! 

  • Hi 

    I’m new to this forum and was reading your post. I have just had a hysterectomy for endometrial cancer and am to receive some radiotherapy in my pelvis. I noticed you said you had some and wonders of your experience I’ve read worrying reports online about the side effects of this and quality to your normal life. 

    any info would be great thanks and really appreciated

    thanks

  • Hi Plod, 

    If you go to the diagnosis and treatment section of the Womb cancer forum - there is a thread on pelvic radiotherapy that may help. I will put a link for you. 

    (+) Radiotherapy Support Thread (inc. Brachytherapy) - Macmillan Online Community

    If you post on there any questions you have we will be able to offer you some support. I had pelvic radiotherapy in Aug/Sept 2022. I found it hard at times, very tiring (25 sessions). Main side effects for me apart from the fatigue were an irritated bladder and diarrhoea. I am now 9 months from the end of radiotherapy and I still have a few problems but I mainly control these through diet. People seem to vary in how they react to the radiotherapy but there is support there and they can give you medication to help with side effects. 

    I would advice against googling for information as some of it out there is not accurate. I will pop a link for some info in case you need it

    I can understand how you are feeling before your treatment starts- I was really nervous but in reality it was a different experience, the radiotherapists look after you so well and I found that I started to see the same faces each day and it helped to chat and share our journey's together. For me the fear of a recurrence was worse than the possible side effects from treatment. 

    Good Luck

  • Hi plod, my first piece of info/advice is DON’T GOOGLE! As jane2511 said, stick to Macmillan for info as it’s reputable and contains up to date info. Please do post on the support thread as Jane suggested as you’ll then likely get responses from several women who’ve had radio in the last year or so. Just to say briefly though that my side effects were minimal and I don’t regret it at all. 

  • Google is always a mistake. I scared myself silly looking on there before I found Macmillan! And none of what I read related to what I actually experienced

  • Thankyou for the replies the information is useful appreciate it 

  • I will echo others about avoiding Dr Google and also to access the radiotherapy thread. 

    I am just about to complete my 25 days. There has been side effects but they have been quite mild. Some bladder irritation that has been helped by drinking plenty and a few bowel issues. I was prescribed some generic Imodium though have only needed to use twice. I switched to a low fibre diet, which has helped.  Some tiredness and I have just allowed myself to nap when necessary.

    My senior radiographer said early on not to be on constant ‘side effect watch’ and for most patients they are mild. Your team will check with you daily about how you are feeling and you can share any concerns.
