Prostate cancer: treatment side effects no one talks about

06 February 2026
Next review due February 2029

For Prostate Cancer Awareness Month this March, we’re sharing the personal journeys of two men who have lived through prostate cancer. Here, Alec Wightman, who is 70 and was diagnosed with prostate cancer in December 2018 tells his story. He lives in Bramhall, North West England, with his wife Nicki and they have five grown up children.

Before 2018, I thought prostate cancer was something other men had. I knew it was common. I’d once worked with a colleague who’d had his prostate removed and he’d struggled with incontinence after that. But personally? I felt fine. Apart from the usual aches and pains as you get older, I felt well. I was a glass-half-full sort of guy.

Confusing symptoms

My first signs were intimate. I’ll be candid because someone else may recognise them. Twice, on ejaculation, I felt a sharp, momentary pain. Another day, I saw a little blood in my urine. That was enough to call the GP.

Because I had symptoms (some men with prostate cancer don’t have any), the initial exam was the finger test. It wasn’t pleasant but it wasn’t painful either. I also had a PSA blood test that came back high – with a PSA level of around 19. PSA stands for prostate specific antigen. This is a protein produced by normal cells in the prostate gland as well as by prostate cancer cells. A raised level can indicate that you have a problem with your prostate, but it’s not necessarily cancer.2 In my case, the high result warranted more tests and a referral to a specialist.

The hospital consultant’s exam was more conclusive, and I was booked for a biopsy. Back then, biopsies were often done through the rectum under local anaesthetic. A tube went in, anaesthetic was injected, and then a dozen needles were used to collect tissue samples from the prostate through the bowel wall.

It was uncomfortable, with sharp stings, and they gave me pads afterwards for bleeding, plus IV antibiotics because of the infection risk. These days, men have an MRI scan first to detect prostate cancer more accurately. This has reduced the number of men who need a biopsy. Today, perineal biopsies have helped to reduce infection risk and made the process less invasive – it’s a welcome change.

Getting a diagnosis

About two weeks later, the results arrived. Mine arrived in a letter that was meant for my GP. To receive the news like that was a shock and really upsetting, especially for Nicki, my wife. But I wasn’t surprised, I am a realist and with my symptoms and PSA results, cancer felt likely.

Most of the sampled tissue contained aggressive prostate cancer, I was told. I was stage 3, and locally advanced. Scans showed it had grown just outside the prostate capsule into a seminal vesicle. This is one of a pair of glands in the male reproductive system that produce fluid that makes up semen.

When I met with the surgeon to discuss the results, he also told me what he’d choose for himself – to ‘whip it out’, he’d said. But I remembered my colleague who struggled after having his prostate removed and I was reluctant to have mine out.

A multidisciplinary team recommended radiotherapy and hormone therapy as the safer bet for me. Operating might have meant cutting into the bladder or bowel to track down the cancerous cells.

Treatment begins

Radiotherapy came in two parts. First, I had high-dose brachytherapy. This was done under general anaesthetic. Radioactive sources were inserted through my perineum into my prostate to deliver a focused blast from inside. I was in hospital overnight and thankfully the painkillers meant I had very little discomfort. I went home the next day with minimal side effects. It left me a little sore for a few days with a small amount of bleeding from where my prostate gland had been punctured.

Ten days later, I started external beam radiotherapy, five days a week for six weeks. At each visit I had to lie still while a radiation machine orbited my pelvis and delivered a dose of radiation to my prostate from outside. This daily external radiotherapy was tiring but very manageable.

Unwanted side effects

After radiotherapy, I began hormone therapy. This is the part men don’t talk about enough. The idea is simple: starve the cancer of testosterone, which is the male hormone that is said to be like ‘food for prostate cancer’.

The lived reality is a lot harder though. Within weeks, the side effects hit me like something out of nowhere. A lot of the symptoms I had were similar to what women get when they’re going through menopause.

Hot flushes would flare unexpectedly – some days I had none, other days three or four – and night sweats soaked the sheets. I experienced fatigue and lost some of my strength, along with my chest hair! My libido shrank to nothing. Achieving an erection became impossible. For two years, I stayed on hormone therapy, and I watched my PSA fall.

I hoped that would be that.

The cancer returns

For a while, it was. I recovered well, returned to work and enjoyed an active life. But in August 2023 my PSA was rising and in October 2023 I was immediately put back on hormone therapy with the regular six-monthly reviews.

In June 2024 I asked for a second opinion to consider other treatments that might be available. In September I had a very detailed PET-CT scan to help doctors understand what was going on. The result was not good, it showed more cancer cells in my prostate, two lymph nodes ‘lit up’ and a possible spot in my pubic bone.

A trial of a second, tightly focused radiotherapy had previously been mooted, but the spread ruled that out. I immediately went back on hormone therapy. The side effects returned like unwelcome houseguests – the flushes, the restless legs, the drag on my energy – and I had to make peace with the long game. It was prolonging my life, which I wanted, so it was worth it.

There were bladder problems too. Urgency went from occasional to constant, and my capacity seemed to halve. I needed to go more often, with less urine.

After the first round of treatment, I had originally trained my bladder capacity back up towards normal using pelvic floor exercises. But now, that was no longer the case. When a urine infection was suspected, my doctor recommended antibiotics. But sometimes the burning and frequency were just radiation irritation flaring. Some nights I was up three or four times. Other nights I was fine. Symptoms came and went.

Effects on my sex life

Sex is the elephant in the room for many men. I’ll say the quiet part out loud: hormone therapy wiped out desire and erections for me.

My wife and I stayed close – hugs, warmth, the daily life we love – but our sex life disappeared. We were okay with that; love and companionship mattered more, and Nicki is very supportive. Other men will feel differently about this aspect, and that’s understandable.

What helped was talking – to each other, to the specialist nurses, to men who’d walked this path before me – and hearing that there are options: tablets, injections, pumps, counselling, and more. No one should be left to figure it out alone.

What I wish I’d known

If you’re at the start of your journey, there are a few practical things I wish I’d known.

First, the pathway has improved: perineal biopsies are now standard in many hospitals, and having an MRI before biopsy helps avoid unnecessary procedures.

Second, radiotherapy can’t be easily repeated. But in some centres, there are trials of carefully targeted second rounds. So, ask your team what’s realistic for your case.

Third, hormone therapy side effects vary wildly; some men breeze through, others struggle. If it’s rough, say so. There are tweaks and supports – for bone health, hot flushes, sleep, mood – that can make a difference.

Emotionally, the hardest stretch was the waiting. Waiting for scans, waiting for results, waiting to hear if the PSA was drifting, rising or diving. I’m a chaser by nature and Nicki and I stayed on the phone, nudging appointments forward and asking for results.

For me the fear is simple: will I live long enough to see my grandchildren through school, graduate and start their lives, and of course to clink glasses with my wife on our next holidays?

On good days, I book those trips and live life fully. On bad days, I breathe, remind myself that early treatment bought me time, and take the next step. My glass is half full, still.

Advice to other men

To the man reading this who’s scared of the finger test or terrified of the word ‘cancer’: please check whether you’re at risk and if you are, go and get checked. The worst stories I heard were from men who waited until they were stage 4 and out of options.

If you catch it early, you’ll likely have more choices than I did six years ago, with good outcomes. If you need radiotherapy and hormone therapy, you’ll be far from alone. Talk. Ask questions. Push for information. And when the side effects arrive, don’t suffer in silence. There’s more help out there than you think.


The expert’s view – Grace Davey, Prostate Cancer UK Specialist Nurse.

Alec's personal prostate cancer – through his diagnosis, treatment and aftercare – highlights experiences, thoughts, and feelings that are shared by lots of men who've been affected by this disease.

Alec mentions that when he was diagnosed, he had a trans-rectal biopsy where they take tissue samples from the prostate via the rectum. Today, it’s common practice that a targeted trans-perineal biopsy is done. This is where prostate tissue samples are taken through the perineum. This practice has reduced rates of infection. You can read more about biopsies and the diagnostic pathway at prostatecanceruk.org.

When a man is diagnosed with prostate cancer, it's common for him to be offered different treatment options. These will depend on how aggressive his prostate cancer is, if it’s spread to other parts of his body, and his medical history.

As in Alec’s case, he was given a treatment of high-dose brachytherapy (a type of internal radiotherapy). He then had external beam radiotherapy alongside hormone therapy treatment. It’s a common treatment plan to have external beam radiotherapy with hormone therapy.

High-dose brachytherapy is rarely given as a stand-alone treatment and is often considered in more high-risk prostate cancers. It involves passing a source of radiation down thin tubes inserted into the prostate under anaesthetic to destroy cancer cells. The source of the radiation is then removed, so no radiation is left in the body.

Alec then went on to have external beam radiotherapy and hormone therapy. External beam radiotherapy aims to destroy prostate cancer cells using high energy X-ray beams targeted from outside the body. Hormone therapy works by stopping the production of testosterone, which helps shrink and stop the growth of any prostate cancer cells.

As Alec has mentioned, these treatments can cause different side effects. Common radiotherapy side effects include fatigue, and bladder and bowel problems. Hormone therapy side effects can vary for each man, but some common side effects include hot flushes, fatigue and changes to your sex life, such as loss of libido.

If you have any questions or concerns about treatment options and side effects, you can speak with your healthcare team.
