That weighs on patients quite a bit. When someone has treatment for a primary tumour, on average there is a 30 to 50 per cent chance of recurrence, across all organs and all tumours, says Finelli. But there is wide variation depending on the cancer. For example, small kidney tumours have a five to 10 per cent chance of recurring, while with certain brain tumours the recurrence may be as high as 70 per cent.
Recurrence is a term doctors use to describe when the primary tumour type has returned in the same or another site. Progression is when the tumour grows. A patient who had a kidney tumour for example, would likely be treated with surgery — a partial nephrectomy removing part of the kidney or a radical nephrectomy removing the entire kidney.
Such a patient had only local disease, and after surgery would be considered tumour-free. The likelihood that an individual develops multiple tumour types in their lifetime, as appears to be the case with Layton, is about 10 per cent.
With the aging population, more people are living longer and we're detecting tumours earlier. It opens the door to more people showing up with another primary tumour elsewhere," says Finelli.
They're totally unrelated. So if you're seeing a year-old man, it's not uncommon to hear that he has prostate cancer and also had a colon tumour or a woman had breast cancer and now she has another tumour. That was the case with former Citytv broadcaster Mark Dailey, who publicly battled prostate cancer and was essentially cured of it. Then he was diagnosed with metastatic kidney cancer — a completely different tumour not related to prostate cancer. Layton lost his fight implies he had a say over his fate.
Buckman said. London-based writer Mike Marqusee, who has discussed his experiences with multiple myeloma in several pieces in The Guardian, says cancer has little to do with battle. Marqusee wrote in Does it reflect some failure of willpower? Similarly, saying someone who is now cancer-free is a "survivor" conveys that he or she is somehow better than the people who didn't make it, said Peter Ellis, staff medical oncologist at the Juravinski Cancer Centre in Hamilton, Ont.
Ellis, who is also an associate professor in the department of oncology at McMaster University. Instead of fixating on the idea of a cancer battle, Dr. Ellis and a growing number of experts in the field say, it is more important to focus on learning to live with cancer.
For those undergoing treatment, this can be much more empowering than the idea they can somehow control the ultimate outcome if they fight hard enough. The Canucks Report newsletter: essential reading for hockey fans Sign up now.
