What you need to know about bowel cancer

Cancer-Cells_1.jpg

Bowel cancer (also known as colorectal cancer) is one of the world’s most common cancers.It affects the lower part of the digestive system: the large intestine and the rectum.

Early detection saves lives

The earlier bowel cancer is treated, the better the prognosis. Average five-year survival rates are as high as 90% IF the cancer is detected before it spreads to other parts of the body.1

Unfortunately, the symptoms are often mistaken for other diseases, like irritable bowel syndrome or peptic ulcers. New Zealand has one of the highest rates of bowel cancer in the world – so it’s vital that we spread the word about bowel cancer and what symptoms to look out for.2

Some of the symptoms which can be apparent in the early stages of bowel cancer are:

  • A consistent change in your bowel habits, including diarrhoea or constipation
  • Rectal bleeding or blood in your stool
  • Regular abdominal discomfort, such as cramps, gas or pain
  • A feeling that your bowel doesn’t empty completely
  • Weakness or tiredness (fatigue)
  • Unexplained weight loss.

Many of these symptoms may have other causes, so it’s important to see your doctor if you experience any of these signs.

Treatment options for bowel cancer

If you are diagnosed with bowel cancer, there are a number of treatments available : surgery, chemotherapy, and biological therapies.

The most suitable treatment for you will depend on many factors, including:

  • The type and size of your tumour
  • Whether the cancer has already spread (metastasised)
  • Your overall health and fitness
  • Your treatment and lifestyle goals

Surgery may be enough to cure early-stage bowel cancer. But once the disease has spread to other parts of your body, some patients may need additional treatment, with a combination of chemotherapy, radiotherapy and targeted therapies such as Avastin ®(bevacizumab).

How Avastin® works

Avastin works by stopping the development of new blood vessels in the body which the cancer cells need to grow and spread. This starves the tumour of the blood supply it needs to grow.

Studies have shown that when Avastin and chemotherapy are given to patients with advanced bowel cancer, it improves the length of time that a patient’s cancer stops growing or spreading, compared with those who received only chemotherapy.3-6

Other studies have shown that patients treated with Avastin may also live longer than those treated with chemotherapy alone.3,4,6

Avastin is not publicly funded which means you will have to pay for this medicine. Avastin is not suitable for everyone, so you will need to speak to your doctor about whether it is right for you.

How to access Avastin

Although Avastin is not a PHARMAC funded treatment, you can access it through a private oncology centre if it’s recommended by your specialist.

What’s more, our cost share programme makes it an affordable treatment option – providing a number of doses free of charge, spreading the cost over time, and capping the total amount you will pay for Avastin. You can get full details of the programme from your specialist.
