Colore**al cancer is one of the most preventable cancers, yet many people delay screening due to common misconceptions.

This 𝗖𝗼𝗹𝗼𝗿𝗲𝗰𝘁𝗮𝗹 𝗖𝗮𝗻𝗰𝗲𝗿 𝗔𝘄𝗮𝗿𝗲𝗻𝗲𝘀𝘀 𝗠𝗼𝗻𝘁𝗵, we are clearing up the facts around colore**al cancer and colonoscopy screening. Early detection allows doctors to remove precancerous polyps before they turn cancerous, often before any symptoms appear.

If you are close to or above 50 years of age, or have a family history of colore**al cancer, screening plays an important role in safeguarding your long-term health.

Prioritise your colore**al health with the colore**al team at 𝗦𝘂𝗿𝗴𝗶𝗰𝗮𝗹 𝗔𝘀𝘀𝗼𝗰𝗶𝗮𝘁𝗲𝘀.

An a**l fistula is an abnormal tract that connects the a**l ca**l to the skin around the a**s.

In many cases, it develops after an infection of the a**l glands, often in relation to an a**l abscess. That said, a fistula can sometimes form even without a preceding abscess.

A**l fistulas can also be linked to underlying conditions such as:

• Crohn’s disease
• Injury/trauma
• Tuberculosis
• Previous radiation treatment
• Cancer

If you’re experiencing recurrent pain or swelling near the a**s, especially with discharge of pus and/or blood, consult a colore**al specialist early.

Yellowing of the eyes or skin is the most recognisable sign of jaundice, but your body may also give other clues.

Look out for these other signs:

• Itchy skin (pruritus)
• Tea-coloured urine and pale stools
• Pain, discomfort, and bloatedness in the abdomen
• Fatigue, with loss of appetite and weight

When bile or bilirubin is not effectively cleared by the liver, or when its passage through the bile ducts into the intestines is obstructed, it can accumulate in the bloodstream and lead to jaundice.

If you notice any of these symptoms, seek early assessment with an experienced hepatopancreatobiliary surgeon.

Inflammatory Bowel Disease (IBD) refers to a group of conditions marked by chronic inflammation of the digestive tract. The two main types are Crohn’s disease and ulcerative colitis.

With early treatment, many IBD patients can achieve long-term remission and lower the likelihood of complications, which can include:

• Bowel perforation
• Intra-abdominal infections with abscess and fistula formation
• Peria**l fistulas formation in Crohn's disease
• Narrowing and obstruction of the bowel
• Blood clots in veins and arteries
• Toxic megacolon (extreme, life-threatening inflammation and distention of the colon)

IBD can also increase the risk of developing colore**al or small intestinal cancer, making regular monitoring and timely care essential. To seek help from experienced colore**al specialist 𝗗𝗿 𝗧𝗮𝗻 𝗪𝗮𝗵 𝗦𝗶𝗲𝘄, reach out today.

If you have hepatitis B or C, liver cirrhosis, or a family history of liver cancer, regular screening is a crucial step in detecting liver cancer early, before symptoms begin.

For hepatitis B/C carriers or patients with cirrhosis of any cause, the risk of developing liver cancer can be about 50–100 times higher.

𝗗𝗿 𝗟𝗲𝗲 𝗦𝗲𝗿 𝗬𝗲𝗲 advises liver cancer screening every six months for individuals with these known risk factors.

A typical screening plan may include blood tests (Hepatitis B/C, alpha-fetoprotein (AFP), and liver function) alongside a liver ultrasound every six months to identify issues early.

Diverticulitis is the inflammation or infection of small sac-like pouches (diverticuli) that can form in the wall of the colon.

Diverticuli is often asymptomatic but becomes more common with age, affecting those aged over 40.

When these pouches become inflamed and cause symptoms, prompt diagnosis is important to enable early treatment.

Severe diverticulitis, especially when accompanied by severe abdominal pain, high fever, or signs of sepsis, can lead to serious complications such as perforation, bowel obstruction, life-threatening haemorrhage, fistula formation, or abscesses.

If you are experiencing symptoms suggestive of diverticulitis, seek assessment from a colore**al specialist.

Liver cysts are fluid-filled sacs within the liver. In many cases, simple liver cysts are benign, cause no symptoms or complications, and do not typically require intervention.

However, surgery is recommended when the cysts becomes large, cause upper abdominal pain/bloatedness, are deemed complex or at risk of becoming malignant.

To remove part of the cyst wall or the whole cyst for treatment and diagnosis, laparoscopic (keyhole) surgery is commonly performed, with minimal pain and downtime as well as low chance of recurrence.

If you notice a lump over the liver area and develop severe pain or a persistent sense of fullness in the upper abdomen, consult a liver surgeon.

Hernias develop when tissues or organs push through the weakened abdominal wall that normally holds it in place. Over time, this can present as a bulge, which can become more apparent with activity or straining.

Although hernias can occur in anyone, the risk is higher when the abdominal wall is weakened or repeatedly placed under strain. Factors that may increase intra-abdominal pressure and predispose you to a hernia include:

• Age
• Smoking
• Obesity and poor nutrition
• Poor recovery after surgery
• Chronic constipation
• Persistent coughing or sneezing
• Lifting heavy loads with poor posture

If you notice a painful bulge in the abdomen or groin, especially when coughing, standing, or bending, consult a hernia surgeon.

If you have been experiencing persistent abdominal pain, bloating and discomfort alongside unexplained changes in bowel habits and blood in stools, an endoscopy can be employed to evaluate the underlying cause.

Providing a visual examination of the inner lining of the digestive tract, an endoscopy can detect and/or treat gastrointestinal and biliary tract conditions such as:

• Colore**al cancer
• Stomach cancer
• Inflammatory bowel disease
• Bile duct disorders (e.g. stones, cancer)
• Benign conditions such as ulcers, inflammation, polyps, piles, and diverticular disease
• Helicobacter pylori infection

At 𝗦𝘂𝗿𝗴𝗶𝗰𝗮𝗹 𝗔𝘀𝘀𝗼𝗰𝗶𝗮𝘁𝗲𝘀, endoscopy procedures are performed by our senior consultant colore**al and hepatopancreatobiliary (HPB) surgeons, ensuring continuity of care from procedure through to review of findings and follow-up. Both male and female specialists are available, so care remains attentive and tailored to your needs.
