What is Colorectal Cancer?

Colorectal Cancer

Colorectal Cancer is the cancer occurred in the colon (the main part of the large intestine) and rectum (the passageway connecting the colon to the anus). It is the most common cancer in Singapore.

Colorectal Cancer is formed from cells lining the colon and rectum, often resulting in the growth of colorectal polyps. Polyps are benign growths in the colon and rectum which may develop into cancer over a long period of time. If polyps are detected, they should be removed in a timely manner.

  • Blood in your stools
  • Change in bowel habits
  • Abdominal pain or discomfort

How is Colorectal Cancer Diagnosed?

Regular screening can detect polyps or colorectal cancer early. Several different tests can be used. Each can be used alone. The Faecal Occult Blood Test (FOBT), a recommended test, is a quick and convenient screening test to detect early stages of colorectal cancer.

Faecal Occult Blood Test (FOBT)It is a simple test conducted on a person’s stool to detect blood. Blood that is hidden in the stool may not appear to be red, and only through the screening test can blood be detected. There are many conditions that cause blood in the stool and this includes piles, peptic ulcer, colonic polyps (benign growth from the lining of the colon) which are pre-cancerous and colorectal cancer. You are encouraged to be screened on a yearly basis.

Double-Contrast Barium Enema This is an x-ray examination of the large intestine using a special substance to improve images.

Flexible Sigmoidoscopy This procedure examines the internal lining of the lower end of your large intestine. A short, lexible, lighted tube is inserted into your rectum and slowly guided into your sigmoid colon.

ColonoscopyA longer, lexible lighted tube is used. This enables the entire large intestine to be examined.

The severity of the Colorectal Cancer is measured by the stage of the disease and indicates how far the cancer has spread.

Stage Treatment
I & II

The common treatments are open surgery, chemotherapy and radiotherapy. However, for those who can’t tolerate or do not want to take common sugery, the preferred treatment is minimally invasive treatment, including interventional therapy, photodynamic therapy, combined therapy of chinese medicine and western medicine, ozone therapy, etc for colorectal cancer stage 1 or stage 2.


In colorectal cancer stage 3, it is safe to take minimally invasive treatment to remove the cancer cells. It only brings lesser side effects than chemotherapy and radiotherapy. Minimally invasive cancer treatment can help avoid taking surgery and it only brings 2mm trauma.


In colorectal cancer stage 4. Open surgery is not effective as a form of treatment and minimally invasive treatment, such as intervnetional therapy, photodynamic therapy, ozone therapy, combined therapy of Chinese medicine and western medicine, can help imrpove colorectal cancer stage 4 better. Doctor team will first discuss patient’s condition and give a recommended treatment plan according to their physical condition, willing and other factors.

How We Treat Cancer?

Interventional Therapy

Interventional Therapy is a new substitute of traditional chemotherapy, which means that a physician introduces instruments such as needles or catheters (long, thin tubes) into the body through tiny(1-2 mm) incisions in the skin. The instruments are then guided by an imaging technique called fluoroscopy to the cancer tumor. In this way, the physician can deliver cancer medicine directly to the tumor.more info

Cryotherapy Therapy

Cryotherapy Therapy, also known as “Argon-Helium Knife Cryotherapy”, is a new substitute of traditional physical therapy. Practically speaking it is “extreme cold + extreme heat” cancer treatment. Generally, a minimum of 10-15 minutes is required to achieve an extreme analgesic (pain relieving) effect while lowering the temperature to the injured area, thus reducing the metabolic rate and swelling associated with tissue injury.more info

Particle Knife

Particle Knife is a new substitute of traditional radiation therapy. With the help of computer Treatment Planning System (TPS), radioactive particles will be implanted into tumors. The particles which release γ-rays can continuously kill tumor and cause destruction targeting tumor cells. With time, the radiation amount would accumulate to be large enough to destroy the DNA double strands of tumor cells.more info
