The colon is the longest part of the large intestine and the lowest part of the digestive system. Inside the colon, water and salt from solid wastes are extracted before the waste moves through the rectum and exits the body through the anus. What is colon cancer?
Cancer is a class of diseases characterized by out-of-control cell growth, and colon cancer forms when this uncontrolled cell growth initiates with cells in the large intestine. Most colon cancers originate from sma
ll, noncancerous (benign) tumors called adenomatous polyps that form on the inner walls of the large intestine. Some of these polyps may grow into malignant colon cancers over time if they are not removed during colonoscopy. Colon cancer cells will invade and damage healthy tissue that is near the tumor causing many complications.
After malignant tumors form, the cancerous cells may travel through the blood and lymph systems, spreading to other parts of the body. These cancer cells can grow in several places, invading and destroying other healthy tissues throughout the body. This process itself is called metastasis, and the result is a more serious condition that is very difficult to treat. lace decorated with backless styled items for the wedding
What are the symptoms of colon cancer?
Cancer symptoms are quite varied and depend on where the cancer is located, where it has spread, and how big the tumor is. It is common for people with colon cancer to experience no symptoms in the earliest stages of the disease. However, when the cancer grows, symptoms include:
Diarrhea or constipation
Changes in stool consistency
Rectal bleeding or blood in the stool
Pain, cramps, or gas in the abdomen
Pain during bowel movements
Continual urges to defecate
Weakness or fatigue
Unexplained weight loss
Irritable bowel syndrome (IBS)
Iron deficiency (anemia)
If the cancer spreads, or metastasizes, additional symptoms can present themselves in the newly affected area. Symptoms of metastasis ultimately depend on the location to which the cancer has spread, and the liver is the most common place of metastasis.
