I was diagnosed with thyroid cancer in May 2017. I had my thyroid removed in the same month and have since been taking levothyroxine.
I'm still trying to work out what caused the cancer and if my thyroid was working properly when I still had it. I had it tested in the past, but the result have always come back as ok. However, I now have a long list of past symptoms that seem to be related to thyroid problems but seem to have disappeared since being on the medication. This includes anxiety, mood swings, extreme insomnia, melasma, rosacea, white spots on my finger nails, thinning hair, psoriasis and eczema, the loss of my handwriting (it has since come back... after 16 years), severe memory problems, concentration issues, depression, extreme sweating caused by being nervous, skin intolerance to sunlight, sinus problems, bowel problems, eventually a goitre and then the diagnosis of thyroid cancer.
I have always looked at these symptoms in isolation but have now realised that they all seem to be linked to thyroid problems. This has had a huge impact on my whole adult life and I'm concerned that my children may have inherited the condition. Is there a way I can have a diagnosis in retrospect? And if there is, is there anything I can do to raise awareness of what happened to me to change the way people are tested for thyroid health?
Thank you very much for your comments in advance!
