Right now, all practising oncologists are seeing patients who unfortunately need to be referred to palliative care. These are patients who could have been cured had they been seen at the onset of symptoms months beforehand. We are seeing situations like that every day. We are encountering patients whose disease is much more advanced than what we used to see.
Certainly, that affects the morale of health care providers, but I don't have any statistics for you.
That said, we are all professionals, and we are realistic. As oncologists, we don't expect to be able to help everyone, so the idea is to see what we can do. Currently, we are treating people, but the fundamental problem is still access to care.
Before the pandemic, 100,000 people in Quebec were waiting for a colonoscopy, the screening for colon cancer, and now that number has hit 150,000. We need resources to meet that demand. It's a huge challenge, but there are solutions.
Oncology is in a unique position. In orthopaedic surgery, for instance, patients receive treatment on a one-time basis, undergoing a knee or hip replacement surgery. It's unfortunate that they have to wait so long for the surgery because it has a significant impact on their quality of life, but once they have the surgery, it resolves their issue. In oncology, however, studies show that, for every 28 days patients have to wait, the mortality rate for colon cancer goes up by 4%. That illustrates how serious the repercussions are when people have to wait months and months to be seen.
When a cancer is diagnosed early, meaning in stage 1, the patient can have surgery, even an endoscopic procedure. The physician can perform a tumour resection, and the rate of recovery is 80%. If the cancer is in a more advanced stage and has spread to the lymph nodes, it's a stage 3 cancer. Without chemotherapy, the patient has a 30% chance of recovery. If the patient receives chemotherapy and radiation therapy, their chance of recovery goes up to 65%, but at the expense of more demanding treatments. Not only does the patient, the person suffering the most, have to be more involved, but so does the care team. The care trajectory is years long, with economic, social and family repercussions.
It's really a disaster in cancer care. We have to make sure we put measures in place to manage the situation. For patients who can be operated on outside the hospital setting, we have to rely on external medical capacity, in the case of a knee or hip surgery, for instance. We keep patients in hospital who need care in connection with abdominal, thorax, colon and other such surgeries.
What we've seen over the past few months and years is that the situation is less problematic in the case of certain diseases. Patients with breast cancer can undergo surgery in ambulatory care units. Patients with breast cancer face delays that are much less significant than patients with other types of cancer. Older cancer patients tend to be put on hold, but their cancers can be just as devastating as the cancers experienced by younger patients.
We are also behind in treating cancers of the bladder, specifically when it comes to cystoscopies. For patients with prostate cancer who could have been operated on, we are sending them for radiation therapy. We have had to change how we manage patients in response to the pandemic, but there will be a price to pay.
The situation is really dire, and patients are the ones suffering the most. I told you earlier that, in 20% of cases, delays in diagnosis were impacting colorectal cancer surgeries in Quebec. I also told you that 9,400 Canadians with a diagnosed colon cancer were expected to die in 2021. If the mortality rate goes up for such a significant share of the patient population, we are going to see dozens, hundreds, thousands of people dying from various cancer-related illnesses.
