Colorectal cancer: what are the usual steps from diagnosis to starting treatment?
Timely multidisciplinary management is key in treating colorectal cancer; for early-stage patients, surgery alone already has a high cure rate, and some patients may need chemotherapy and/or chemoradiotherapy before or after surgery (Hong Kong Cancer Strategy 2019, July 2019). The Hospital Authority has had cancer case managers for breast and colorectal cancer patients since 2010-11, and they now cover many types of cancer, including breast cancer, colorectal cancer, gynaecological cancers and blood cancers (Government paper to the Legislative Council, July 2025).
Financial support and welfare: what to do first?
A first step is to ask the treating doctor or a nurse for a referral to a medical social worker; patients and their families can also apply for medical social services directly to the medical social services unit stationed at a public hospital or specialist clinic, and health care staff at the hospital or clinic, other government departments or welfare agencies can refer a case as well (Social Welfare Department, August 2023).
Medical social workers provide counselling on the emotional, family and caregiving problems that illness brings, help patients plan their discharge, and provide financial or material assistance, for example medical fee waivers, applications for fund subsidies, and referrals for patients and their families to apply for social security allowances (Social Welfare Department, May 2023). For the help available, see Cancer financial support in Hong Kong.
Compiled by this site: when you see the doctor, you can also ask when and where the next follow-up or test will be, and which doctor or case manager to contact; the Hospital Authority has cancer case managers who coordinate the diagnosis and treatment process for cancer patients (government paper submitted to the Legislative Council, July 2025). If you are thinking of moving hospitals or seeing another doctor, you can get the referral letter, test reports and images together first; for the documents needed, see Moving from public to private, or private to public.
What are the usual steps for colorectal cancer from diagnosis to starting treatment?
Compiled by this site: based on the sources in the table below, the general steps for colorectal cancer from first finding a problem to starting treatment are as follows; the order of the steps and the time they take vary from person to person.
The order of tests and treatment for an individual patient is decided by the treating doctor according to the patient's condition.
| Step | What official sources say |
|---|---|
| Finding something abnormal | Participants in the Colorectal Cancer Screening Programme whose faecal immunochemical test result is positive are referred to a colonoscopist enrolled in the programme for a Government-subsidised colonoscopy (Department of Health press release, March 2026); anyone with symptoms such as a change in bowel habit, blood or mucus in the stool, tenesmus (a continued urge to open the bowels after a bowel movement), abdominal discomfort, or unexplained weight loss or fatigue should see a doctor early (Hong Kong Cancer Strategy 2019, Annex One, July 2019) |
| Tests and diagnosis | Most Hospital Authority cancer services (for example diagnostic radiology, pathology, endoscopy, surgery, radiotherapy, chemotherapy and palliative care) are provided mainly in regional hospitals or cancer centres (Hong Kong Cancer Strategy 2019, July 2019) |
| Multidisciplinary discussion | Timely multidisciplinary management is the key to successful treatment of colorectal cancer (Hong Kong Cancer Strategy 2019, Annex One, July 2019); the Hospital Authority has multidisciplinary team clinics or meetings for some cancer types (Hong Kong Cancer Strategy 2019, July 2019) |
| Starting treatment | For early-stage patients surgery alone already has a high cure rate, and some patients may need chemotherapy and/or chemoradiotherapy before or after surgery; for patients with limited spread, aggressive local treatment should be considered in addition to conventional systemic treatment (Hong Kong Cancer Strategy 2019, Annex One, July 2019) |
| Coordination | The Hospital Authority has run the cancer case manager programme for breast cancer or colorectal cancer patients since 2010-11, helping to coordinate the diagnosis and treatment process; there are currently more than 40 cancer case managers, covering breast cancer, colorectal cancer, gynaecological cancers, blood cancers, musculoskeletal tumours and urological cancers, among others (Government paper to the Legislative Council, July 2025) |
Why does colorectal cancer need a multidisciplinary team?
A considerable proportion of colorectal cancer patients can now be cured, and timely management by multiple professions together is the key to successful treatment; the role of the cancer case manager is to help with the diagnosis and treatment process (Hong Kong Cancer Strategy 2019, Annex One, July 2019).
The Hospital Authority has multidisciplinary team clinics or meetings for some cancer types; Hospital Authority cancer services will take a patient-centred multidisciplinary team approach, with teams of doctors, nurses, medical social workers, clinical psychologists, radiation therapists, physiotherapists, occupational therapists, dietitians and other professionals caring for the social and psychological needs of patients and their families (Hong Kong Cancer Strategy 2019, July 2019).
Which specialties are involved? How do I look up fees and financial support?

What can I ask the doctor?
Compiled by this site: examples of questions you can ask: What type of cancer has been diagnosed, and what stage is it? Which tests are needed next, and who will arrange them? Will the treatment plan be discussed by several specialties together? Which doctor or case manager will be my contact? What will it cost, and what financial support is available?
