Yes: Blood in the stool may be from diverticulosis, a benign condition. Large polyps can cause bloody stools as can large internal hemorrhoids.

A 43-year-old female asked:

What is tested when you are asked to give a stool sample? Is there something that alerts them to any types of cancer in the test?

See below: If the stool sample is to check for blood, then that is all that is tested for. Presence of blood, even microscopic, can be a suggestion for possible cancer. It can also be due to hemorrhoids, anal fissures, constipation, or intestinal infections. If colon cancer, the type/stage cannot be determined from the stool sample. That is why a colonoscopy is then done if the stool sample is + for blood.
A female asked:

Other then cancer, what else can cause thin stools?

Thin stool: Based on your question, it seems as though you're asking about stool caliber (diameter) rather than consistency (solid/liquid) when you say "thin". Anything that narrows the diameter of the canal can narrow diameter, often hemorrhoids. If loose stools, diet and infections are common causes.
A 31-year-old member asked:

If I have occaisional thin stools, could it be cancer?

Possible: thin stools suggest narrowing of bowel but this should be constant and if a tumor present there should be progression. If this doesn't change on diet then one should consider colonoscopy. In future a simple stool test will tell whether colon cancer protein present in stool and therefore if there is a lesion present or not.

A 26-year-old male asked:

I have flat stool mixed with some normal stool? Should I be worried about cancer?

Cancer unlikely: While it is possible, it is extremely rare to see colon cancer in a 26 year old. Colon ca can cause a mechanical obstruction resulting in narrow stool. It is a constant rather than intermittent problem. Change in bowel habits can result from dietary changes, dehydration, stress, as well as other diseases of the colon such as inflammatory bowel disease. Ask your doctor is it continues.
