Important: Prostate cancer is the most common cancer in men in the UK — around one in eight men will be diagnosed in their lifetime. When detected early, it is highly treatable and often curable. A new diagnosis can feel overwhelming, but understanding your options clearly makes an enormous difference. I am here to guide you through every step.

Already been told your PSA is raised?

If you have a raised PSA result and have not yet had an MRI or biopsy, please visit my Raised PSA page first. It explains the full diagnostic pathway — including multiparametric MRI and targeted transperineal biopsy — and how to get an accurate diagnosis as quickly as possible.

Raised PSA — assessment and diagnosis →

This page focuses on what happens once a diagnosis of prostate cancer has been made — covering the treatment options, the benefits of robotic surgery, and what recovery and follow-up look like.

Understanding your diagnosis

Not all prostate cancers behave the same way. Once a diagnosis is confirmed, the key factors that guide treatment are the grade of the cancer (how aggressive it is) and its stage (how far, if at all, it has spread). These are assessed using the Gleason/Grade Group system and imaging.

Low risk

Gleason 6
Grade Group 1

Slow-growing, confined to the prostate. Active surveillance or treatment are both appropriate depending on individual circumstances.

Intermediate risk

Gleason 7
Grade Groups 2–3

Clinically significant cancer. Definitive treatment — surgery or radiotherapy — is typically recommended.

High risk

Gleason 8–10
Grade Groups 4–5

More aggressive cancer. Prompt treatment is important. Surgery and multimodal therapy are discussed in detail.

Treatment options

Treatment is always tailored to the individual — taking into account the grade and stage of your cancer, your age, overall health, and personal priorities. All options are discussed openly so that you can make an informed decision.

Active surveillance

For carefully selected men with low-risk, slow-growing prostate cancer, active surveillance — closely monitoring the cancer without immediate treatment — is a well-established and safe approach. It avoids the side effects of treatment unless and until they become necessary. Regular PSA tests, MRI scans, and occasional repeat biopsies form part of the monitoring programme.

Robotic-assisted radical prostatectomy

Mr Sri's primary surgical specialism

Surgical removal of the prostate using the da Vinci robotic surgical system. Robotic surgery offers precision that significantly exceeds conventional open or laparoscopic approaches, particularly in preserving the bladder neck, urethral sphincter, endopelvic fascia and delicate nerve bundles responsible for continence and sexual function. This is the most common treatment for localised and locally advanced prostate cancer. It can also be used in select cases where cancer has remained or returned following either radiotherapy or focal therapy.

Mr Sri performs nerve-sparing robotic prostatectomy as a high-volume procedure, with outcomes that reflect the benefits of surgical experience and advanced technique.

Radiotherapy

External beam radiotherapy (EBRT) or brachytherapy (internal radiotherapy) are effective alternatives to surgery, particularly in men who prefer to avoid an operation or who have medical conditions that increase surgical risk. Radiotherapy is also used after surgery if there are signs that cancer has returned. Mr Sri works closely with clinical oncology colleagues for patients where radiotherapy is the preferred or most appropriate pathway.

Focal therapy

Selected patients only

Focal therapy — using high-intensity focused ultrasound (HIFU) or cryotherapy to target only the affected area of the prostate — may be considered in men with low or intermediate risk disease that is small, single-site, and confined within the prostate. It preserves more healthy tissue and can reduce side effects compared to whole-gland treatment. However, it carries a higher risk of cancer recurrence and is most appropriately discussed in the context of clinical trials or highly selected cases. It is not suitable for all patients and is not a replacement for proven treatments in many situations.

Why robotic surgery — and what to expect

For most men with localised prostate cancer choosing surgery, robotic-assisted prostatectomy using the da Vinci system is the gold standard. The precision of robotic technique — particularly in identifying and preserving the neurovascular bundles — translates directly into better functional outcomes for patients.

Nerve-sparing technique — preserving one or both neurovascular bundles — is used wherever it is oncologically safe to do so, and significantly improves the recovery of erectile function after surgery. Potency recovery is a gradual process and varies by age and baseline function, but in appropriate candidates it is meaningfully better with robotic nerve-sparing compared to non-nerve-sparing or open surgery.

Most patients are discharged after one night in hospital, go home with a catheter for around one week, and return to light activity within days. The majority are back to their normal routine within two to four weeks.

Survivorship — life after prostate cancer treatment

Treatment is only the beginning. What happens afterwards — monitoring, recovery, and quality of life — matters just as much. My survivorship programme is built around three priorities.

Cancer monitoring

Regular PSA surveillance to detect any sign of recurrence early, with a clear plan agreed at the outset. If PSA rises after surgery, further assessment and treatment options are discussed promptly.

Continence recovery

Specialist physiotherapy support for pelvic floor rehabilitation begins before surgery and continues afterwards. The great majority of patients achieve excellent continence, particularly following nerve-sparing robotic technique.

Erectile function recovery

Andrology support — including penile rehabilitation — is a priority for all appropriate patients after nerve-sparing prostatectomy. Early intervention significantly improves long-term potency outcomes, and I work with specialist colleagues to deliver this as part of structured follow-up.

Frequently asked questions

I have just been diagnosed — what happens next?

The first step is a clear and supportive consultation to go through your diagnosis, what it means, and what all your options are. There is rarely a need to make an immediate treatment decision — taking a little time to understand your situation and ask questions is always appropriate. I will guide you through every stage.

Will I be incontinent after surgery?

Temporary leakage is common in the first weeks after prostatectomy, but the great majority of men achieve excellent continence with time and pelvic floor physiotherapy. 80–90% of patients treated with nerve-sparing robotic technique are dry or leaking only minimally at one year. The experience and technique of the surgeon — alongside the robotic approach — are key factors in this outcome. I expect patients to be dry at night and use a single pad for safety at six weeks post-operatively. Achieving this typically places you ahead of the curve in terms of continence recovery.

Will surgery affect my sexual function?

Erectile function recovery after prostatectomy depends on several factors — including age, baseline function, and whether nerve-sparing was possible. Recovery takes time, typically months to a year or more. With nerve-sparing robotic technique and structured penile rehabilitation support beginning early after surgery, the outcomes are meaningfully better than with non-nerve-sparing or open surgery. This is always discussed honestly and in detail before any decision is made.

How do I know whether surgery or radiotherapy is right for me?

Both surgery and radiotherapy are effective treatments for localised prostate cancer, with comparable cancer control rates in most risk groups. The right choice depends on your cancer characteristics, your priorities regarding side effects, your general health, and personal preference. I discuss both options openly, and where appropriate refer to oncology colleagues, so that you can make a fully informed decision. For most patients there is no right or wrong answer — it comes down to personal preference in terms of treatment journey and outlook. The key is to take your time and not rush into any treatment decision.

How soon can I get back to normal life?

Most patients are discharged after one night in hospital and return home with a urinary catheter for approximately one week. The majority are back to light daily activities within days and to their normal routine within two to four weeks. More strenuous exercise and heavy lifting are typically resumed at six weeks.

Do I need a GP referral?

No — you can self-refer directly, whether you have a confirmed diagnosis or are still in the investigative stage. Many patients come having already received a diagnosis and wish to discuss their options with a specialist before deciding on treatment.
