I think I may have colon cancer. I have noticed that I am currently showing the following symptoms: constipation, blood in your stool, persistent abdominal discomfort, and a feeling that my bowels don't empty completely. Whenever I go to the bathroom (and even when I don't) I have dark-red blood that runs out of my anus. I am concerned and scared. I have a family history of colon cancer. I earliest signs that started to show was about 2-3 weeks ago, that was just mild cramping in my abdomen that I thought was because of my intestines trying to digest the food I had eaten. Now I am showing all the signs I have listed. I would go to my doctor but I no longer have health insurance that covers my doctor and I don't want to sit in the ER for hours. I hope that you can help me.
