What happens if my bowel cancer comes back?
In many cases, treatment for bowel cancer will be successful, but the cancer can come back or recur.
There are no clear statistics on recurrence, but in 2002, the journal Gut suggested that in around 50% of cases, the cancer may return.
Around 80% of recurrences happen within 2 years of having a bowel cancer operation.
What is the outlook following treatment for bowel cancer?
Every person is different and responds differently to bowel cancer treatment. The survival rate for people with bowel cancer depends on the extent of the cancer at the time of diagnosis (the stage of the cancer) and the person's response to treatment.
The following factors determine how well a person will do after treatment for bowel cancer:
Size of the cancer. The size of the tumour and how deep it has gone into the tissue affects whether or not it will return. The deeper the tumour invades tissues, the higher the chance of recurrence.
Number of lymph glands involved. The lymph glands are part of the body's immune system defences. The more lymph glands that have been affected by the cancer, the more likely the cancer will return.
Spread to other organs. If bowel cancer is detected at a later stage there's a higher chance it may have spread beyond the bowel to other parts of the body, such as the liver or lungs. This may increase the chances of the cancer recurring. In this case, additional chemotherapy or radiotherapy may be needed to help prevent further spread of the cancer.
Quality of the surgery. This is most important for rectal cancers, where surgery can be difficult.
Many people who have had bowel cancer live normal life spans. Bowel cancer treatments are improving all the time, but in some cases several treatments may be needed or a combination of treatments, including surgery, chemotherapy and radiotherapy.
What happens if bowel cancer comes back?
If bowel cancer has come back in only one part of the body, treatment may consist of an operation to remove the cancer. If the cancer has spread to several parts of the body, a specialist may offer either chemotherapy or radiotherapy. You may also choose to participate in a clinical trial testing new chemotherapy medications or biological therapy.
