Is Gastric Cancer the Same as Colorectal Cancer?
Listening to the term “cancer” can send shivers down your spine! But nowadays with the high success rate of it’s treatment, it need not be so. As you know, cancer starts when abnormal cells in the body grow out of control and form tumors.
Gastric cancer or colorectal cancer are cancers of the digestive tract that have the potential to spread and damage other parts of the body.
Although they fall into the same category of gastrointestinal cancers, they are dramatically different. Let’s take a glance at them individually and understand the difference between the two.
What is gastric cancer (GI)?
The stomach is part of the digestive system that connects the esophagus (food pipe) to the small intestine. Cancers arising in the stomach are called gastric cancers.
Adenocarcinoma is the most common variety of stomach cancer. Adenosqaumous carcinoma, neuroendocrine tumours, GIST, lymphoma are the other less common varieties of cancer arising in stomach.
Gastric cancer can develop in any part of the stomach and spread further into surrounding nodes, other organs such as dudodenum, pancreas, large intestine (colon), peritoneum and liver.
What is Colorectal cancer?
Colorectal cancer starts in the colon (large intestine) or the rectum (lower part of the large intestine where stool is stored before being excreted by the body). These cancers termed rectal or colon cancer, depending on the initiation site.
Colon cancer and rectal cancer are often grouped together because they have several common features. Adenocarcinoma is the most common variety of colorectal cancer. However there are other less common varieties of cancers as well.
