Welcome Flora That is the same as me though I am through treatment now apart from Tamoxifen and DIEP. Its common for cysts and things to show on CT and good they have said its a cyst. I had about 8 things show on mine and a few very scary tests before all OK'd.
Fairywren That must have been wonderful to be in Borneo and yes Land Below the Wind was the book.
Polly Swimming with sharks sounds exciting.
I also love kayaking / rowing / canoeing and DD has inherited it and has a job doing it which is great as it pays very well and she gets fit.
I have had something wrong with my back for a couple of days now and struggle to move at times, get like a paralysis for 10 mins or so and have pain. I called the breast care nurses and they got oncology to call, also have pins and needles and numbness. DH reckons its being 50. They said they probably will want a spine MRI to check for spread to spine but am awaiting to hear. Hopefully just nerves for pins and needles and numbness and bad back hopefully is my new pillows that are memory foam though the nurse was like hmm how would that work. Never had a bad back in my life. It is mainly lower back and looks like its rare that's cancer but eek looked up survival if it is and said under 2 years average. Oh well nothing I can do about that but I would want to go to Borneo first. 😂I was 99.9% certain it would be nothing until I googled the symptoms and have them all. But then I have had every symptom of a few cancers before and negative then breast cancer no family history no symptoms until a massive lump appears and bang cancer.
