Colon cancer starts in your large intestine (colon). It develops from certain growths or polyps in the inner lining of the colon. Doctors perform screening tests to check for precancerous polyps before they turn into tumours. If it is left untreated, it can spread to other parts of your body. Read on to know everything about this condition and if you need colon cancer surgery.
Causes of colon cancer
Similar to all other kinds of cancer, colon cancer occurs when cells grow and divide in an uncontrollable manner. According to medical researchers, certain inherited conditions, lifestyle choices, and risk factors increase your chances of having colon cancer. Some of these risk factors have been listed below.
Alcohol use: Both men and women must limit alcohol to one or two servings a day to reduce their risk of colon cancer. As drinking alcohol excessively can also put you at risk.
Smoking: If you use tobacco products, you have a greater chance of developing the disease.
Having a diet full of processed or red meat: In case you have a diet full of processed or red meat, you can be at risk of developing several conditions, including colon cancer.
Being obese: Eating high-calorie and high-fat foods regularly can lead to the development of colon cancer.
Symptoms of colon cancer
● Blood in stool
● Changes in bowel habits
● Bloated stomach
● Abdominal pain
● Weight loss
● Shortness of breath
1. Screening tests: Colonoscopy is a screening test for diagnosing colon cancer. Other screening tests are as follows:
- Virtual colonoscopy: A virtual colonoscopy is a kind of X-ray that checks for tumours, ulcers, and polyps in the rectum and colon.
- Flexible sigmoidoscopy: In this screening test, a sigmoidoscope is used to see inside your rectum and lower colon.
- Fecal immunochemical test: This test detects blood in your stool. Medical pathologists examine it to find blood that may not be apparent to the naked eye.
- Fecal DNA tests: Fecal DNA tests look for genetic mutation and signs of blood in your stool.
Types of surgery for colon cancer
- Polypectomy: Polypectomy is performed for the removal of polyps from your colon.
- Laparoscopic surgery: In laparoscopic surgery, the surgeon makes small abdominal incisions to insert the laparoscope, which has an attached camera. It transfers the images on the monitor, and the doctor uses these visuals to navigate their surgical instruments to remove the tumour.
- Endoscopic mucosal resection: This rectum surgery is done for the removal of stage 1 and stage 2 colorectal cancer with a colonoscope.
- Partial colectomy: The surgeon removes the affected part of the colon along with some healthy tissue surrounding the area.
- Lymph node removal: The colon cancer doctor removes the lymph nodes to stop cancer from spreading.
We have discussed causes, symptoms, diagnoses, and treatment for colon cancer. If needed, you can reach out to a colon cancer surgeon for proper diagnosis and treatment of the disease.
