Canadians diagnosed with most common cancers are more likely to survive the disease if they detect it at an earlier stage. The study offers the first ever Canadian estimates of five-year cancer survival by stage at diagnosis. Highlights include:
- Women diagnosed with breast cancer experienced five-year net survival rates of 100% when the disease was detected in stage I, 92% in stage II, 74% in stage III and 23% in stage IV;
- For colon cancer, five-year net survival decreased from 92% at stage I to 11% at stage IV, whereas for prostate cancer, the prognosis was close to 100% for the first three stages, then declined to 41% at stage IV; and
- Overall, net survival rates exceeded 90% for all cancers studied that were caught in stage I, except for lung cancer.
