Anthony Antoniou sees people who have been referred by their GP or by self-referral.

He can help:

People with symptoms – however minor – which may be associated with a colorectal condition

If you have any of the following symptoms, however minor they appear, you must seek medical advice – whether initially from your GP or by self-referring yourself to Anthony or another colorectal surgeon (the information on this – or any other – website is designed to help but must never be used for self-diagnosis):

  • Bleeding from the anus
  • Blood in stools
  • Change in bowel habits eg constipation, diarrhoea
  • Pain on bowel movement
  • Abdominal pain
  • Unexplained weight loss
  • Recurrent nausea or vomiting
  • Faecal incontinence
  • Piles / haemorrhoids

Unfortunately the stigma around bowels combined with the belief that pain and bleeding are invariably due to haemorrhoids, means many people do not seek prompt medical help, but it is vital to do so. The good news is in the vast majority of cases (94%), the symptoms above are due to benign (non-cancerous) colorectal conditions, and early diagnosis will bring peace of mind. However, in the small number where the condition is malignant (cancerous), time is a huge factor and treating a tumour early can make a big difference to picking it up 3 or 4 years down the line.

If you have any of the symptoms described above, in the first instance feel free to arrange a consultation. Mr Antoniou will take your ‘history’, examine you, have a chat and answer all your questions – with the likelihood being he can put your mind to rest about any worries. A popular option for people without insurance or with limited funds is to pay for an immediate initial consultation with Mr Antoniou, and once they have peace of mind they do not have cancer they are happy to wait and have further tests and treatment on the NHS.

His training in diagnostic endoscopy (which most colorectal surgeons refer on) means Mr Antoniou is very unusual in offering a ‘one stop shop’, resulting in a very rapid diagnostic and treatment pathway. He can offer patients presenting symptoms any or all of the following:

  • Initial consultation
  • Diagnostics / tests eg blood tests, x-ray, colonoscopy
  • Surgery / non-surgical treatment

People diagnosed with a colorectal disease – wanting surgery carried out by an experienced consultant colorectal surgeon

If you have already been diagnosed with a benign or malignant colorectal condition, you may want the reassurance of having your surgery performed by a leading colorectal consultant. Mr Antoniou may be a particularly suitable choice if your condition requires one of his specialist areas of interest:

  • Laparoscopic (‘keyhole’/minimally invasive) colorectal surgery
  • Colorectal cancers
  • Anal surgery including anal cancer
  • Recurrent cancer surgery
  • Endoscopic surgery (gastroscopy, colonoscopy, OGD & flexible sigmoidoscopy)


People with no symptoms – wanting bowel cancer screening to prevent colon cancer

Most UK screening programmes are breast and cervical, yet in men and women colon cancer is the 3rd most common cancer (after lung and breast cancer) – and the only cancer where the risk can be completely eradicated with simple, effective screening. In the US using colonoscopies (an internal examination of the colon with a small camera attached to a flexible tube that is gently inserted into the anus) for bowel check-ups is commonplace, but the continuing stigma around anything bowel-related in the UK means this incredibly effective procedure is much rarer here.

Bowel cancer screening with a colonoscope is so effective because it shows up colonic polyps (small growths) which are the predisposing factor to colon cancer – some can go on to develop into cancer. By identifying and then removing any colonic polyps, your risk of bowel cancer can be reduced to zero.

The 20 minute procedure is carried out under conscious sedation combined with pain medication, resulting in many patients experiencing minimal or even no discomfort. Bowel preparation takes 24 hours and is done at home on the previous day. After the colonoscopy the sedation should wear off within a few hours and you will be back to normal – with the peace of mind you will have a minimal risk of one of the UK’s most common cancers.
