Canada: 1 in 2 Canadians will get cancer: reports Canadian Cancer Society

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 men and by about 17 per cent among women.

"Declines in death rates have been largely driven by decreases in lung cancer incidence and mortality, so tobacco control in general has had a big impact on our death rates," Smith said, 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.
