  • Hello Jackie562,

    Thanks for getting in touch with us and welcome to our online community.  My name is Linda and I’m one of the Cancer Information Nurses on the Macmillan Support Line.

    It’s important to report new symptoms, so it’s good that your daughter made an appointment to see her GP and they have tested a poo sample. Blood in the poo sample does not necessarily mean that she has cancer but with the weight loss too, it’s important to try and find the cause.

    You mention colonoscopy, it’s normal for a colonoscopy to be recommended to investigate the blood. Unfortunately, the presence of blood can be caused by cancer, but it can also be caused by other bowel conditions.

    It’s natural to worry about what the tests may show and waiting for results can be very difficult.  

    I hope this information is useful. Please don’t hesitate to get back in contact by email, webchat or phone, if you need further information or support.

    The Macmillan Support Line offers practical, clinical, financial and emotional support. You can call us free from landlines and from most mobile phone networks on 0808 808 00 00, 7 days a week, 8am – 8pm.

    Best Wishes
