What does a colon cancer doctor do?

A colon cancer doctor works closely with other doctors such as a surgeon, oncologist, radiation oncologist and gastroenterologist to treat colon cancer. In general, a colon cancer doctor manages intestinal tract diseases, which consists of the colon, rectum, anal canal, and perianal area. Some of the conditions of the intestinal tract include: 

  • Abscesses and fistulae 
  • Anal skin tags
  • Colon and rectal cancer
  • Diverticulitis 
  • Fissures
  • Haemorrhoids
  • Inflammatory bowel disease
  • Irritable bowel syndrome 
  • Polyps 
  • Rectal prolapse

When to visit a colon cancer doctor 

Most patients may not be visiting a colon cancer doctor directly but through a referral from another doctor. You can seek direct help from a colon cancer doctor if you experience symptoms such as anal itching or burning, anal or rectal pain, anal warts or bumps, bleeding or other discharge from the anus, faecal incontinence. 

It is important to let your colon cancer doctor know that you have experienced any of the above symptoms. This is because your colon cancer doctor needs to understand the full extent of your symptoms to accurately diagnose your condition and decide which treatment to go with. 

What type of procedures does a colon cancer doctor perform?

Depending on your condition, your colon cancer doctor may perform several types of diagnostic and treatment procedures. The most basic diagnostic procedure is inserting medical instruments through the anus and into the rectum and colon to check for issues. The medical instruments are equipped with lighted cameras that help visualise the colorectal passage. Some other common procedures that a colon cancer doctor perform include: 

  • Endorectal ultrasound 
  • Digital rectal examination 
  • Anoscopy 
  • Proctoscopy 
  • Sigmoidoscopy 
  • Surgery 

Treatments that a colon cancer doctor performs

Laparoscopy surgery 

A laparoscopy, also known as keyhole surgery, involves a colon cancer doctor cutting through four or five small incisions through the patient’s abdomen. Then, a telescope camera is inserted into one of the cuts, and the enlarged image of the internal abdominal organ is projected on the television screen. 

Transanal total mesorectal excision 

The transanal total mesorectal excision is a technique that combines an abdominal and transanal endoscopic approach to overcome limitations and facilitate standard laparoscopic. A colon cancer doctor will take this approach for patients with mid or low rectal cancer. 


 A colon cancer doctor uses chemotherapy to treat colorectal cancer. This method is the usage of drugs to kill cancer cells. Chemo drugs attack fast-dividing cells quickly, so they work effectively against cancer cells. However, other cells in the body, such as hair follicles, can be affected by the chemotherapy and lead to side effects such as hair loss. 


A colon cancer doctor may use radiotherapy, which required high radiation or particles to kill cancer cells. Radiotherapy is more commonly used to treat rectal cancer rather than colon cancer. When radiotherapy is being performed simultaneously as chemotherapy, it will be more effective in treating colon cancers. 

How to become a colon cancer doctor 

In Singapore, an aspiring colon cancer doctor would need to undergo an additional one to two years of training to specialise in colon surgery. A practising colon cancer doctor in Singapore would have completed at least 14 years of medical school and training, consisting of a four-year undergraduate program and four to five years of post-graduate general surgery residency. 

What to expect during a visit to a colon cancer doctor 

When a patient first visits a colon cancer doctor, they need to register themselves at the clinic. Patients may have been referred by other doctors or word of mouth. After registration, the colon cancer doctor will conduct a general health screening by asking questions about the patient’s health. There will be a consultation session where there are physical examinations to diagnose a patient. 


The colon cancer doctor will then decide on a treatment that is suitable for the patient’s condition. The treatment would usually be either endoscopy or a colonoscopy. The colon cancer doctor will brief the patient on the treatment details and what to expect during the procedure itself. The procedure will usually be a quick and smooth one. 

Follow up 

One or a few follow up appointments may be needed after the procedure. Follow up appointments are essential because the colon cancer doctor will need to review the test results with the patient and explain the next steps. A follow-up appointment usually takes place one to two weeks after the procedure. 

Challenges a colon cancer doctor faces

One of the most challenging complications after colorectal surgery is surgical site infection, ileus, bleeding, and anastomotic leakage. These are tricky situations to handle, even for the most experienced colon cancer doctor. 

How much does colon cancer surgery cost? 

The colon cancer surgery cost depends on the complexity of the condition and the procedure used, which range from $40,000 to $70,000. Colon cancer surgery is a complicated procedure that often requires a team of doctors, nurses, and advanced equipment to perform and ensure the highest success rate. Patients will also need to be hospitalised for seven to ten days after the surgery. 

How to find the best colon cancer doctor 

Word of mouth recommendations is usually your best bet at finding the best colon cancer doctor for you. However, online research and reviews also play an important role. Another alternative is to book a consultation with a colon cancer doctor of your choice and feel comfortable with the doctor before deciding whether to undergo treatment with the particular colon cancer doctor.
