Report says one in two Canadians expected to be diagnosed with cancer.
TORONTO • Almost one in every two Canadians is expected to be diagnosed with cancer in their lifetime and one in four Canadians will die from the disease, a new report by the Canadian Cancer Society predicts.
In 2017, an estimated 206,200 Canadians will be diagnosed with some form of cancer and an estimated 80,800 will succumb to their malignancy — making cancer the leading cause of death in Canada, the charitable organization said Tuesday in its annual cancer statistics report.
“Currently, every year we’re seeing an increase in the number of cancer cases in Canada,” said the society’s epidemiologist Leah Smith. “So between now and 2030, for example, we expect to continue to see a dramatic increase in the number of cancers diagnosed in Canada.
“That is a reflection of the growing and aging population,” she said. “About 90 per cent of all the cancers that we expect to be diagnosed in 2017 will be among Canadians 50 years of age and older.”
About 45 per cent of those cases will occur in people age 70 and older, said Smith, noting that as more people move into old age, the number of cancer cases will rise.
Despite the projection that cancer will cause the deaths of one in four Canadians, cancer mortality rates have been declining since their peak in 1988. Over the past three decades, deaths due to cancer have fallen by more than 30 per cent among males and by about 17 per cent among females.
“Declines in death rates have been largely driven by decreases in lung cancer incidence and mortality,” she said, “so tobacco control in general has had a big impact on our death rates,” especially among men who historically had higher smoking rates than their female counterparts.
Increased rates of screening for breast cancer and improved treatments have also bolstered survival among women.
Sarah Metcalfe of Ottawa is all too familiar with the ravages of cancer, which has affected eight people in her family.
When she was a child, an aunt died of breast cancer. But cancer really hit home when Metcalfe was a new mom in her early 30s and her husband developed osteosarcoma in his upper arm, which was successfully treated with a bone transplant and long courses of “dramatic” chemotherapy.
About the same time, three uncles succumbed to lung cancer, mostly due to smoking, and then her father developed fatal colon cancer.
Her brother was subsequently diagnosed with skin cancer, though he is doing well, she said. In 2011, Metcalfe learned she had breast cancer.
“Just as I’d finished treatment, my mom found a lump on her thigh” that turned out to be a soft-tissue sarcoma. Despite treatment, the cancer spread and her mother died about two years later.
