Hey,

The only way to know if you have colorectal cancer (colon cancer) is a biopsy of the colon or rectal area that appears cancerous as Denisedds said. these tests can be performed by a gastrointerologist or a colon and rectal surgeon.

However the symptoms that should send you to one of these specialists for testing are:-

Usually the first symptom is bright red rectal bleeding. This does not always mean that you have colon cancer but you should seek medical care for this symptom as colorectal cancers often bleed. If the cancer is far from the rectum instead of bright red bleeding, a sign of colon cancer is dark, tarry stools, another symptom that should send you straight to the doctor.

Bleeding into the intestine results in a low blood count or anemia. A symptom of anemia is lack of energy. in any unexplained anemia the diagnosis of colon cancer must be considered.

New onset constipation is another symptom. as the cancer grows it begins to block the intestine so stools cannot pass. with certain types of colon cancers, diarrhea can also be a symptom. Diarrhea that does not resolve in a few days must also be investigated.

When the intestinal tract is partially or completely blocked, a feeling of fullness, decrease in appetite, and weight loss can be a result. these are symptoms of colon cancer until proven otherwise.

Bright red rectal bleeding, dark tarry stools, fatigue, constipation, continuous diarrhea, weight loss, lacks of appetite, and a feeling of fullness can all be symptoms. It is important to seek medical help if you have any or especially a combination of these symptoms as they can be colon cancer symptoms. The only way to know that you have colorectal cancer is to see a doctor who can diagnose the cause of the symptoms.

I hope its not serious

Still, it’s important to understand what you need to look for, so if something does pop up, you make sure to seek medical attention immediately.

so im afraid that my friend is becoming anorexic. are these symptoms of this disease? she only eats breakfast (fruit) and dinner and she workouts out everyday and she is really concerned about her weight even though she is wears a zero. she always wear sweatshirts because she doesn't like the way she looks in t shirts. she is really concerned about people calling her fat or not skinny. and she is always trying to come up with a new way to lose weight. is that like maybe the beginning of anorexia?

Yep, it's likely a phase she's going through and hopefully she'll grow out of it before she does too much damage. my personal opinion is that nothing will help until the person hits bottom and gets exhausted from constantly worrying about weight.

Is she 15% below the prescribed weight for her age? Does she have distorted perceptions on weight and body image? Does she have eating disturbances? if so then yes she has anorexia. you should encourage her to see a doctor.
