Specific site. Intestinal cancer can mean any type of cancer affecting any portion of the intestines (from the small intestine to the large intestine). Colon cancer affects the large intestine only.
Most common. Intestinal cancer is colon cancer or adenocarcinoma of the large intestine. Cancer of the small intestine is quite a bit less common and can be of various tissue types.
Depends. A colon cancer is a cancer of the large intestine. An intestinal cancer could be located anywhere in the small or large intestine. But small intestinal cancer is quite rare, so I suppose that most "intestinal" cancers would be located in the colon statistically.
Location, Incidence. Colon cancer arises from a site involving the large intestine commonly called the colon (ascending, transverse, descending, sigmoid). Intestinal cancer usually refers to small intestinal cancer that arises from the duodenum, jejunum or ileum. Colon cancer is much more common compared to cancer arising from the small intestines which is considered rare.
Colon more specific. The intestinal tract is composed of the small intestine, large intestine or colon, and rectum. Virtually all cancers of this system arise in the colon and rectum, with cancers of the small intestine exceedingly rare. Therefore, intestinal cancer generally refers to colon or rectal cancer, which is more anatomically specific. Adenocarcinoma is the most common type of cancer that occurs.
Yes. The large intestine and the colon are words to describe the same anatomic structure in the abdomen.
See below. The colon is part of the gastrointestinal tract. The colon is also referred to as the large intestine. The small intestine is the bowels between the stomach and the colon. "small intestine cancer" refers to cancer of the small bowels which includes the duodenum, jejunum and ileum. The term "intestinal cancer" may be used loosely to mean "small intestine cancer.".
Can be the same. The intestines are a group of structures including stomach, small intestine and large intestine (which is the colon). Cancers can form in any of these sites, but large intestine (colon) cancer is most common. So colon cancer is a type of intestinal cancer.
Sort of same. All colon (large intestine) cancers are intestinal cancers but not all intestinal cancers are colon cancer (you can also get small intestine cancer).
Colonoscopy ; biopsy. If you are concerned about possible colon cancer, see a physician. He/she will take a history and perform a physical examination. If you have a concerning history/symptoms or physical/lab findings, then the physician may refer you for a test called colonoscopy in which a scope is passed through the length of the colon and the entire colon is visualized. Biopsies can be performed if needed.
See, below. Iron deficiency anemia, weight loss, change of bowel habits, constipation, unexplained weight loss.
Colon cancer. Some of the symptoms are fatigue from blood loss and anemia, constipation if tumor advanced and causing obstruction, loss of appetite, weight loss, unexplained deep venous clots. These are some symptoms, it does not mean this all going to happen.
No. Usually this is a sign that it is a large cancer that has grown over time and is ending up blocking the colon and causing obstruction.
Sometimes. Obstruction can be a sign of colon cancer, but obstruction can also occur for non-cancer reasons. A common non-cancer reason is adhesions, which are caused usually by scar tissue from previous surgery.
No. This is more commonly a late symptom of colon cancer. It is almost impossible to obstruct for right sided colon cancer. Intestinal obstruction can presnet with a changes in bowel habits or constipation.
No. Hopefully it is more rare with good family practitioners making their patients have adequate health surveillance. Typically they are picked up with these screening endoscopies, blood in stool, weight loss etc. Occasionally you will find a stoic individual who ignores symptoms, or avoids doctors, and thus presents with obstruction instead.
All too often. It is not uncommon for colon cancers to not cause symptoms until they reach a size sufficient to block the lumen of the colon; at this point, people will typically present with cramping abdominal pain, severe bloating, and vomiting. These findings often indicate an advanced cancer that may require emergency surgery (+/-stent). The goal of screening is to find cancers before any symptoms develop.
