Colorectal cancer survivorship in adults
Informed by recognized medical guidance
Overview
Survivorship means living with, through, and beyond a cancer diagnosis. For people who have finished colorectal cancer treatment, it focuses on regaining strength, managing long-term side effects, and watching for signs of the cancer coming back. It is a unique phase that combines medical follow-up, healthy habits, and emotional support.
Key facts
- Survivors often need regular check-ups for at least 5 years after treatment.
- Long-term side effects from treatment can be managed with support from your care team.
- Healthy lifestyle changes can help reduce the risk of the cancer returning.
Survival rates for colorectal cancer have improved greatly over the past few decades. Many adults complete treatment and go on to live active, full lives.
Colorectal cancer affects both men and women, usually over the age of 50. Survivorship issues can affect anyone who has gone through treatment, but the type of treatment and your general health shape your experience.
Symptoms
- Sudden severe abdominal pain
- Passing a lot of blood or clots from the back passage
- High fever with chills
- Inability to pass gas or stool, with bloating and sickness
- Sudden shortness of breath or chest pain
- ⚠New or worsening pain in your belly or back passage
- ⚠Bowel habit changes that last more than a few days
- ⚠Signs of infection around a surgical wound
- ⚠Severe tiredness that stops you from caring for yourself
Common symptoms
- Fatigue that lasts for months after treatment
- Changes in bowel habits, such as more frequent stools or leakage
- Numbness or tingling in the hands or feet
- Feeling very tired during or after activity
- Sexual problems such as erectile dysfunction or vaginal dryness
- Gut pain or bloating after eating
Symptoms in children
- Colorectal cancer is extremely rare in children. For a young person who has had it, survivorship focuses on growth, nutrition, and maintaining a healthy emotional life after intensive treatment.
Symptoms in older adults
- Older adults may have more trouble recovering from surgery and may feel fatigue, reduced appetite, or dizziness. They also may be taking other medicines that can interact with their cancer follow-up care.
Causes
Main causes
- Most colorectal cancers start as small growths called polyps on the inside of the bowel. Over time, some polyps turn into cancer. The exact cause is often unknown, but changes in the cells lining the bowel are the start.
- After treatment, long-term side effects often come from the cancer treatment itself, such as surgery, chemotherapy, or radiation therapy, not from the cancer alone.
Risk factors
- Age, especially over 50
- Family history of colorectal cancer
- A diet high in processed meat and low in fibre
- Lack of physical activity
- Drinking alcohol and smoking
- Having had radiation therapy to the pelvis (for late bowel effects)
When to see a doctor
See a doctor urgently if:
- New bleeding from the back passage
- Persistent diarrhea or constipation that starts suddenly
- Unusual or worsening abdominal pain
Book a routine appointment if:
- Follow your planned follow-up visits, even if you feel well.
- Mention any change in bowel habits at your regular appointment.
Diagnosis
During follow-up, doctors use physical exams, blood tests, imaging scans, and direct inspection of the bowel to look for signs of cancer or long-term problems.
Tests that may be done
- Colonoscopy (a thin tube with a camera used to see the inside of the bowel)
- CT scan (a detailed X-ray that shows the body from different angles)
- Blood tests to check general health and tumor markers
- Fecal immunochemical test (a stool sample test for hidden blood)
What to expect at your appointment
You will have a personal follow-up schedule with appointments every few months at first, then less often over five years. You may be tested for cancer recurrence or new polyps. It is normal to feel nervous before these appointments.
Treatment
Treatment for colorectal cancer depends on the stage and location. It often combines surgery to remove the cancer, chemotherapy (medicine that kills cancer cells), and sometimes radiation therapy (high-energy rays). After treatment, survivorship care includes monitoring and managing side effects.
Self-care at home
- Keep a record of your symptoms and treatments
- Take rest when your body needs it
- Stay as active as you are able
- Talk to your care team before starting new medicines or supplements
- Build a support network of people who understand
Medical treatments
Medical follow-up may include regular blood tests, imaging scans, and colonoscopies to watch for new polyps or recurrence. For persistent side effects like nerve pain, bowel leakage, or changes in hormone levels, your doctor may refer you to specialists. Treatments for these problems can include medicines, procedures, or simple lifestyle adjustments, but your clinical team will decide based on your individual needs.
When is surgery considered?
Surgery may be needed again if a follow-up finds a new tumour or a narrowing in the bowel. It is not common, but your team will discuss it with you if it is recommended.
Living with this condition
Life after treatment often feels different. You may need to pace yourself, plan meals that are easy on the bowel, and communicate openly with your family and employer about what you need.
Lifestyle tips
- Eat a plant-rich diet with plenty of fibre
- Remain physically active
- Limit alcohol
- Avoid smoking
Diet and exercise
Choose small, frequent meals if your bowel is sensitive. Include fruit, vegetables, beans, and whole grains. Start exercise with gentle walking and build up slowly. If you have a stoma or poor bowel control, speak to a dietitian or specialist nurse for personal advice.
Mental health and emotional wellbeing
Survivors often feel anxious, sad, or grateful all at once. These feelings are normal. It can help to talk about them with a counsellor or join a local cancer support group.
Prevention
It may not be possible to prevent every case, but you can reduce your risk of colorectal cancer recurrence by following a healthy lifestyle and attending all recommended follow-ups.
Vaccines
There is currently no vaccine to prevent colorectal cancer. However, ask your doctor about keeping up to date with other vaccines while your immune system recovers.
Screening programmes
People who have had colorectal cancer need regular screening (such as colonoscopy) to check for new polyps or recurrence. Follow the schedule your specialist gives you.
Complications
If left untreated
- Ignoring recurrent symptoms can lead to the cancer growing and becoming harder to treat.
- Rarely, a blocked bowel or heavy bleeding can be life-threatening.
Long-term outlook
Many colorectal cancer survivors live many years and enjoy a good quality of life. Staying active, eating well, and attending follow-ups gives you the best chance of a long and healthy life.
