Hi this might sound minor but I’ve lost family members to cancer including my sister to breast cancer.my daughter started loosing blood from her back passage about 2 years ago and was prescribed  bisodol from the Gp and it stopped how ever it started again 2 weeks ago this time worse she’s been passing dark looks like dark blood clots mucus and bright red blood when she wipes. She’s been to her GP who took bloods and a stool sample Wednesday her GP called today and said that her bloods have come back fine but he has referred her to urgent suspected cancer clinic for further tests she has no other symptoms and when she does have a bowel movement it’s normal she’s only just turned 30  never smoked eats a healthy diet and is a ODP. 

I’m going out of my mind with worry she doesn’t want me to tell anyone until we find out what it is but I just don’t know what to think what to do or what to say does this mean that there is a high possibility that she has colon cancer ? 

sorry for such a long message I just need to get it out of my head

thank you
