UK Cancer and Transition Service
The UK cancer and transition service (UCATS) provides specialist clinical advice and support for trans, non-binary, and gender diverse people affected by cancer, and their care teams.
For trans and non-binary people, a cancer diagnosis may be made more difficult because of:
Dysphoria related to the investigations or treatments
Effects of gender-affirming hormone treatments on cancer growth
Effects of cancer treatments on gender-affirming hormones and surgeries
Extra burden on mental health
UCATS puts people at the centre of their cancer journey and helps them to work with teams providing their gender and cancer care to make the best choices for them.
What UCATS offers
Specialist clinical advice on the integration of gender care and cancer care.
Multiprofessional MDT discussion.
Review of available evidence related to treatment decisions.
A platform for shared decision making.
Letter of recommendations.
Signposting to other important services such as therapy, psychosexual counselling and fertility preservation
The opportunity to participate in research.
How does it work?
UCATS is a virtual multidisciplinary team meeting and clinic combined. We accept patient and clinician referrals for advice and review.
Who is eligible to access UCATS?
UCATS is available for people who identify as trans, non-binary, gender-diverse, or are exploring their gender identity.
You must have a current or past diagnosis of cancer, a history of cancer, or another hormone-sensitive benign tumour (e.g. meningioma).
We triage referrals according to clinical need and will provide urgent advice where necessary.
Our clinic runs once a week, on Mondays. Waiting times vary depending on urgency, but appointments are usually offered within a few weeks.
Appointments usually take place by video call, but we can also offer in-person or telephone appointments.
Appointment links are sent 1–2 weeks in advance. We aim to be flexible where several healthcare professionals need to attend and will also take the patient’s availability into account.
What happens at the appointment?
Appointments last up to one hour. At the initial appointment, we tend to have only the patient and the UCATS team present for the first half an hour. We may then invite multiple members of the care team and external experts to join.
We ask questions about cancer history, gender-affirming care, medical history and treatment priorities.
We may present evidence about risks and benefits of different treatments. We will aim to come to an agreement with patients and care teams about the best way forward and provide with recommendations.
We may signpost to other services that may be helpful.
What happens after the first appointment?
Patients and their care teams are sent a letter by email outlining what was discussed at the appointment.
Further appointments may be required to gain consensus or for ongoing support.
Once you have had your first appointment, patients and care teams continue to have access to UCATS and our specialist nurse.
Our email is monitored regularly and we offer cancer nurse support in standard working hours.
Please do not delay any urgent treatment while waiting for a response or until after your appointment.
Our clinics are only held on Monday afternoons and are usually booked two weeks in advance but we can provide more urgent advice to clinical teams, and sometimes more urgent appointments, when needed.
Where can I access more support?
OUTpatients is a charity supports those in Lesbian, Gay, Bisexual, Transgender, Intersex and Queer communities affected by cancer. They provide peer support, education, and create information leaflets for the community.
The UCATS team is comprised of oncology and gender specialists. Our team is majority queer and has trans and gender-diverse individuals.
