Fast  facts    Cancer  statistics    

   

• Every  hour  of  every  day,  an  average  of  21  Canadians  will  be  diagnosed  with  cancer  and  nine  will  die  from  the  disease.  

• Almost  half  of  all  Canadians  (41  per  cent  of  females  and  46  per  cent  of  males)  will  develop  cancer  in  their  lifetimes.    

 

 

• A  quarter  of  all  Canadians  are  expected  to  die  of  the  disease.

• Prostate  cancer  is  the  most  commonly  diagnosed  cancer  in  Canadian  men,  accounting  for  25  per  cent  of  all  new  cases  in  men.  

• Breast  cancer  is  the  most  commonly  diagnosed  cancer  in  Canadian  women,  accounting  26  per  cent  of  all  new  cases  in  women.  

• Prostate,  breast,  lung  and  colorectal  cancers  account  for  more  than  half  (52  per  cent)  of  all  newly  diagnosed  cancer  cases.

• The  number  of  new  cancer  cases  and  deaths  continues  to  rise  as  the  Canadian  population  grows  and  ages.  However,  rates  of  the  disease  are  generally  stabilizing  for  new  cases  and  declining  for  deaths.  

• An  estimated  187,600  new  cases  of  cancer  will  be  diagnosed  in  Canada  in  2013  (excluding  non-­‐melanoma  skin  cancer).  

• There  will  be  an  estimated  75,500  deaths  from  cancer  in  Canada  in  2013.  

• More  than  16,300  Albertans  and  people  living  in  the  Northwest  Territories  will  be  diagnosed  with  cancer  in  2013  and  more  than  6,300  will  die.  

• Lung  cancer  continues  to  be  the  leading  cause  of  cancer  death  for  both  Canadian  men  and  women,  taking  the  lives  of  more  people  than  breast,  prostate  and  colorectal  cancers  combined.  

• People  diagnosed  with  cancer  today  have  a  better  chance  of  survival  than  they  did  just  over  a  decade  ago  (63  per  cent  of  Canadians  now  survive  cancer,  compared  to  56  per  cent  in  the  1990s).  

May  2013       Page  4  of  8  

• On  average,  mortality  rates  have  declined  by  two  per  cent  per  year  for  the  following  cancers:  colorectal,  lung  and  prostate  cancers  in  men;  breast,  ovarian  and  cervical  cancer  in  women;  larynx,  stomach  and  non-­‐Hodgkin  lymphoma  cancers  in  both  sexes.  

• In  2013,  almost  all  cancer  deaths  in  Canada  (95  per  cent)  will  occur  in  people  over  the  age  of  50.  Most  of  these  deaths  (61  per  cent)  will  occur  in  people  over  the  age  of  70.  

• Cancer  is  the  leading  cause  of  death  in  Canada,  accounting  for  30  per  cent  of  all  deaths.

Fast  facts    Liver  cancer    

   

• While  liver  cancer  is  still  considered  a  rare  cancer  (accounting  for  an  estimated  one  per  cent  of  all  new  cancer  diagnoses  and  deaths  in  2013)  it  is  one  of  the  fastest  rising  cancers  in  Canada.  

• The  incidence  rate  of  liver  cancer  has  tripled  in  Canadian  men  and  doubled  in  Canadian  women  since  1970.  

• In  2013,  approximately  2,100  Canadians  will  be  diagnosed  with  liver  cancer  –  1,550  men  and  490  women.  

• In  2013,  approximately  1,000  Canadians  will  die  from  liver  cancer  –  780  men  and  240  women.  

• Liver  cancer  has  a  very  poor  prognosis  with  a  five-­‐year  relative  survival  rate  in  Canada  of  only  20  per  cent,  meaning  four  out  of  five  people  diagnosed  with  liver  cancer  will  die  within  five  years.

• In  Canada  in  2009,  premature  death  from  liver  cancer  resulted  in  14,700  potential  years  of  lost  life.  

• Liver  cancer  is  the  third-­‐leading  cause  of  cancer  death  worldwide  after  lung  and  stomach  cancers,  accounting  for  about  700,000  deaths  annually  around  the  world.  

• In  most  cases,  liver  cancer  does  not  cause  any  symptoms  until  very  late  in  the  course  of  the  disease.  

• People  with  liver  cancer  often  present  with  large,  late-­‐stage  tumours  that  are  generally  not  curable.  

• The  main  risk  factors  for  primary  liver  cancer  are  chronic  hepatitis  B  and  C  infections,  smoking,  heavy  alcohol  use,  obesity  and  diabetes.  

• Approximately  600,000  Canadians  are  infected  with  hepatitis  B  or  C,  according  to  the  Public  Health  Agency  of  Canada.  

• In  2011  (the  most  recent  year  that  complete  data  is  available)  there  were  over  500  Albertans  living  with  liver  cancer.*  

• In  2013,  more  than  170  Alberta  men  are  expected  to  be  diagnosed  with  liver  cancer  and  nearly  130  will  die  of  the  disease.*  

• In  2013,  approximately  80  Alberta  women  are  expected  to  be  diagnosed  with  liver  cancer  and  just  over  60  will  die  of  the  disease.*  

• Among  Alberta  males,  the  incidience  rate  for  liver  cancer  increased  by  2.77  per  cent  per  year  between  1992  and  2011.*  

• Among  Alberta  females,  the  incidence  rate  for  liver  cancer  increased  by  2.12  per  cent  per  year  between  1992  and  2011.*  

• Among  Alberta  males,  the  death  rate  for  liver  cancer  increased  by  1.53  per  cent  per  year  between  1992  and  2011.*  

• Among  Alberta  females,  the  death  rate  for  liver  cancer  did  not  significantly  change  between  1992  and  2011.*

More  about  hepatitis  B  

• Hepatitis  B  infection  accounts  for  nearly  one-­‐quarter  (23  per  cent)  of  liver  cancer  cases  in  developed  countries  such  as  Canada,  but  the  percentage  is  much  higher  in  parts  of  the  developing  world  where  hepatitis  B  is  common,  such  eastern  Asia  and  sub-­‐Saharan  Africa.  

• Hepatitis  B  can  be  prevented  with  a  vaccine.  All  provinces  in  Canada  offer  universal  vaccination  against  this  form  of  hepatitis,  although  the  vaccination  strategies  vary  from  province  to  province.  

• Universal  childhood  vaccinations  for  hepatitis  B  have  been  widely  available  in  Canada  since  the  mid-­‐1990s.  

• Hepatitis  B  is  commonly  passed  through  exposure  to  contaminated  blood  or  body  fluids  between  sexual  partners,  by  sharing  needles  among  drug  users  or  by  sharing  personal  care  articles,  such  as  razors,  scissors,  nail  clippers  or  toothbrushes,  with  an  infected  person.  

More  about  hepatitis  C  

• Hepatitis  C  infection  accounts  for  approximately  30  to  50  per  cent  of  liver  cancer  cases  in  North  America.  The  percentage  is  lower  in  the  developing  world.  

• There  currently  is  not  a  vaccine  for  hepatitis  C  but  research  to  develop  a  vaccine  is  underway.  

• In  Canada,  hepatitis  C  is  spread  through  exposure  to  contaminated  blood  and  is  sometimes  transmitted  through  sexual  activity.  

 

Reducing  the  risk  of  liver  cancer  

There  are  a  number  of  things  Canadians  can  do  to  reduce  their  risk  of  liver  cancer,  including:  

• protect  themselves  against  hepatitis  infection  

o people  can  get  vaccinated  for  hepatitis  B  if  they  haven’t  already  done  so;  there  is  no  vaccine  for  hepatitis  C,  but  research  to  develop  a  vaccine  is  underway  

• practise  safe  sex  

• don’t  share  needles  or  other  drug-­‐use  equipment  

• get  treated  if  they  have  a  hepatitis  infection  

o treatment  of  chronic  hepatitis  B  infection  can  reduce  the  amount  of  virus  in  a  person,  which  may  lead  to  a  lower  risk  of  liver  cancer  

o treatment  of  chronic  hepatitis  C  infection  can  reduce  and  in  some  people  eliminate  the  virus  completely  

• limit  the  amount  of  alcohol  they  drink  

• be  a  non-­‐smoker  

• be  physically  active  and  maintain  a  healthy  body  weight

Glossary Potential  years  of  lost  life  –  an  estimate  of  the  number  of  years  of  life  lost  due  to  premature  death.  It  provides  an  alternative  measure  to  death  rates  by  taking  into  account  average  life  expectancy  and  giving  more  weight  to  deaths  that  occur  among  younger  people.    Five-­‐year  relative  survival  ratio  –  a  measure  of  the  impact  of  cancer  on  life  expectancy  that  compares  the  survival  of  people  diagnosed  with  cancer  to  the  survival  of  a  comparable  group  of  people  in  the  general  population.  Five-­‐year  relative  survival  ratio  is  the  preferred  measure  for  assessing  population-­‐based  cancer  survival.
