Colon & Rectal Cancer     Urdu


The term ‘bowel cancer’ is used to describe both:

• Cancer of the large bowel (colon)

• Cancer of the back passage (rectum).

These cancers are known as colorectal cancers.

How does bowel cancer develop?

Bowel cancer usually develops from a polyp in the bowel. A polyp is a type of growth that forms in the lining of the bowel. Most polyps remain benign but, if left untreated, some may turn into a cancerous tumour. Removal of polyps can prevent bowel cancer.


What causes cancer of the bowel?

Little is known regarding the cause of bowel cancer, although we are aware of some risk factors. Most of these are associated with lifestyle:  ‘Western’ type diet – high meat intake (particularly processed meat: sausages, bacon, burgers and ham). Low intake of vegetables and possibly fruit.

• Inactive lifestyle.

• Smoking.

• Obesity.

• Some inflammatory bowel diseases.

• A family history of bowel cancer – if two or more members of your immediate family have had bowel cancer or one member of your family was diagnosed under the age of 45.

What are the symptoms of bowel cancer?

Symptoms vary according to the position and size of the cancer. The following can be possible symptoms of bowel cancer and include:

• A persistent change in bowel habit for six weeks such as: going to the toilet more often, or trying to go, looser or more diarrhoea like stools or severe constipation.

• Repeated bleeding from the back passage or blood in the bowel motion with no anal symptoms (no irritation, lumps, straining with hard stools or soreness).

• Unexpected weight loss.

• Anaemia (unexplained tiredness and fatigue due to a low level of red blood cells).

• An unexplained lump in the tummy.

These symptoms do not definitely mean that someone has bowel cancer, however, they should always be taken seriously.

How do I know I have bowel cancer?

Bowel cancer is usually diagnosed using the results from a number of tests and investigations:

• Tests with a specialised flexible telescope to look inside the bowel.

• X-ray tests and scans.

• Blood tests.

How is bowel cancer treated?

There are three standard types of treatment for bowel cancer. These are surgery, radiotherapy and chemotherapy. Each of these can be used alone or in combination with each other, depending on the extent and location of the disease.

When a diagnosis of bowel cancer is made, each individual case is discussed at a multi-disciplinary team (MDT) meeting where cancer specialists consider which treatment(s) may be the best option.

Following the MDT meeting your consultant surgeon will discuss the results of your investigations and treatment options with you. Your surgeon will also answer any questions you have on the benefits and risks of these treatments.

What type of surgery is performed?

The type of operation performed depends on the extent and position of your cancer. Where possible the cancer and surrounding bowel and tissues will be removed and the two ends of the bowel joined back together. Sometimes a stoma (bag on the tummy to collect bowel waste) may need to be performed; this can be temporary or permanent.

Following surgery a pathologist examines the piece of bowel removed. The pathologist describes the growth of the cancer according to a standard reporting system

What is radiotherapy?

Radiotherapy involves directing a beam of radiation at the cancer; it is similar to having an X-ray. Radiotherapy is usually given on a daily basis as an out-patient over a period of time. Each treatment takes just a few minutes to complete and is painless. Courses of treatment are short (five days) or long (four to six weeks).


Radiotherapy can be used to:

• Shrink rectal cancer prior to surgery.

• Relieve symptoms if surgery is not appropriate.

• Reduce the risk of a cancer coming back after surgery.

• Treat cancer if it comes back after surgery.

What is chemotherapy?

• Chemotherapy is a systemic treatment in that it treats the whole body. It involves the use of anti-cancer drugs to destroy cancer cells or stop them from multiplying.

• Chemotherapy may be given with long course radiotherapy before surgery.

• Chemotherapy given after surgery is usually over a period of about six months as an out-patient.

• Sometimes chemotherapy is used instead of surgery if an operation is judged not to be suitable.

• Drugs may be given by injection into a vein or by mouth in a tablet form.

Often people who have seemingly the same disease have different treatments. This is because tumours can be of different sizes, different types and in different parts of the bowel and/or body. If chemotherapy is suggested, a consultant oncologist will explain which anti-cancer drugs are suitable for you and discuss the aims of treatment and any possible side effects.
