Health advocates are pushing for all provinces and territories to lower the screening age for colorectal cancer to 45 as a growing number of younger adults are getting the disease.
'Our objective is to ensure that young Canadians do not ignore the signs and symptoms just because of their age and that they are aware of their family medical history and risk level, as we call on our provincial and territorial health ministries to lower the screening age for colorectal cancer throughout the country to 45,' said Barry Stein, president and CEO of Colorectal Cancer Canada, in a statement on Tuesday.
Colorectal cancer screening is currently offered for those at 'average-risk' across Canada. Those at average risk are aged 50 to 74 who don't have symptoms and personal or family history of the following:
colorectal cancer
certain polyps
genetic conditions like Lynch syndrome
inflammatory bowel diseases such as Crohn's or colitis.
Colorectal Cancer Canada, a national non-profit group, said its advice follows the change made to U.S. guidelines in 2018 to include those aged 45 to 49 for screening based on 'evidence-based recommendations' from the American Cancer Society. Australia also reduced the starting age for bowel cancer screening to 45 from 50 in 2024.
What is the risk?
Although individuals aged 50 and older are mostly getting the cancer, Colorectal Cancer Canada said it's not 'an old person's disease' and the risk now is greater for younger adults compared to past generations.
Those born after 1980 are two to 2.5 times more likely to get colorectal cancer before they turn 50, according to Colorectal Cancer Canada. What's more, it said younger patients tend to be diagnosed with the disease at more advanced stages, which creates 'unique challenges' for prognosis and treatment.
Early onset colorectal cancer is rising among those below age 50, Colorectal Cancer Canada added. At the same time, Canada is seeing a declining number of cases and deaths for those 50 and older.

Health Canada won't fight Alberta's plan to charge for COVID vaccines

OTTAWA — Health Canada isn't quarrelling with Alberta Premier Danielle Smith's announcement that most Albertans will soon have to pay out of pocket for COVID-19 shots. Article content Nicholas Janveau, a spokesperson for the federal agency, said Tuesday that the decision is entirely the premier's to make. Article content Article content 'Provinces and territories are responsible for the delivery and administration of their respective vaccination programs including determining which vaccines are publicly funded, eligibility criteria, and other relevant considerations,' wrote Janveau in an email to the National Post. Article content Article content Smith announced Friday that, starting this fall, most of Alberta's 4.8 million residents will need to pay out of pocket for COVID vaccines, if they choose to get them. Article content She said on her weekly call-in radio show that the change was a necessary cost-saving measure, after the Liberal government announced in January that federal funding for vaccines would end this year. Article content 'Now that we have to develop our own new program for payment … we want to avoid wastage (and) make sure that people get it as a priority who are most at risk, and then make (vaccines) available to whoever else wants (them),' said Smith. Article content Smith noted that more than a million doses were left unused and discarded during the 2023-24 respiratory virus season, costing taxpayers $135 million. Article content 'The sad part was we threw away over a million doses, because people just don't want to get the (COVID) vaccine in the same rates as others,' said Smith. Article content 'I think it's because (the COVID vaccine) doesn't work particularly well,' said Smith, when asked what she made of the shortfall. Article content A government press release said that provincially-funded vaccines will still be given free of charge to dependent seniors, the immunocompromised and those on social assistance. Article content All other Albertans, including those over the age of 65, will be required to pay the full cost of the vaccine. Article content The release doesn't say how much this will be but references a Center for Disease Control costing estimates of $110 per vaccine dose. Article content Even with the changes, Alberta is budgeting $49 million for COVID vaccines for the 2025-26 respiratory season, versus $19 million for flu shots and $2 million for Respiratory Syncytial Virus (RSV) shots. Article content Toronto-area physician Shawn Whatley, formerly the head of the Ontario Medical Association and a fellow at the Macdonald-Laurier Institute, said that the permissibility of out-of-pocket costs under the Canada Health Act is largely a question of whether the services involved are deemed 'medically necessary.'

Language revitalization linked to better Indigenous health, says UBC research

New research to come from UBC highlights the positive link between Indigenous language revitalization and the health and wellbeing of First Nations communities. (Courtesy: MoA) Editor's note: This story mentions suicide. If you or anyone you know is struggling with mental health there are a number of ways to get help, including by calling or texting Suicide Crisis Helpline at 988. A list of local crisis centres is also available here. Indigenous communities have long touted the wellness benefits of speaking and sustaining their ancestral languages, and now there's evidence that supports it – courtesy of new research from the University of British Columbia. The review, led by a UBC team and assisted by the University of Toronto and the University of Sydney, saw researchers analyze more than 260 studies from Canada, the United States, Australia and New Zealand for references of language use being connected to better health. The most surprising element of the findings wasn't that there was a connection between the two but the extent of that connection, with various aspects of health shown to be benefitted by First Nations members conversing in their own language. 'I think a lot of people are aware that there is a link between the two at some capacity, but there hasn't really been a thorough review to see what this link really is, how prevalent it is, what it means exactly,' said Julia Schillo, a PhD student in the department of linguistics and co-author of the study. 'I hear a lot about how language revitalization has been important for First Nations people for things like trauma healing and for mental health, but there were so many articles talking about how it played into things like physical health and diet and spiritual well-being, too,' she said, noting how around 78 per cent of the material discussed a positive correlation. Stronger educational performance, greater social connection and, in some cases, lower suicide rates, were also found to be directly connected to the use of Indigenous language. Many of the findings, particularly from studies in Australia and northernmost Canada, showed how there are typically better outcomes when health services are offered in First Nations languages, with patients more likely to better understand their treatment plans, and feel more comfortable and respected in a medical facility. Likewise, there were worse health outcomes reported when patients weren't able to receive health care in the language they needed. 'There were some reports of issues with people receiving health care without being able to provide informed consent, or translators not being called even when they were available,' said Schillo. The research process had been lengthy and involved Schillo and the study's lead author Louise Harding searching a number of databases, pulling around 10,000 potential articles and going through the summaries of those articles for relevant information. That search was then narrowed to 1,000, then a few hundred. Schillo hopes it will be the first of many studies into the relationship between health and Indigenous language use, as further research is needed to truly understand the finer elements, like the potential confounding variables. 'Socioeconomics, English language, fluency, things like that that need to be looked at in more detail to actually get a solid picture of what's going on here,' she said. Mark Turin, an anthropologist, UBC associate professor and co-author of the study, said the next step should be two-fold. First of all, there needs to be 'grounded, site-specific, ethnographically informed and culturally rich studies' of the specific Indigenous communities who have established language programs. Turin said he would also like to see a pivot towards research that focuses more on the strength and resilience of First Nations communities. 'Some of the formative research has been about negative associations, whether through causation or correlation, namely a decline in Indigenous youth suicide being related to language transmission and cultural continuity,' he said. 'This is extremely important research, but also really painful because of the devastating effects of suicide in Indigenous communities.' For further research and efforts to revive Indigenous language to get underway, however, funding, of which there is little, is required. 'Right now, so much language revitalization work is being done on short-term funding grants that are not guaranteed to be renewed,' said Schillo. 'That interruption undermines the long-term investment that it could provide to people's health.'

New measles exposure sites confirmed in southern Manitoba

Manitoba health officials announced Tuesday that four new measles exposure sites have been identified in southern Manitoba. The Manitou Motor Inn in Manitou, the Triangle Oasis Restaurant in Winkler, VB's Entertainment Center in Winkler and the Steinbach Church of God in Steinbach have all been confirmed as measles exposure sites, a news release said Tuesday. Anyone who was at the Manitou Motor Inn bar on June 9 between 3 p.m. and 6:30 p.m. or VB's Entertainment Center on June 9 between 5 p.m. and 10 p.m. should monitor symptoms until July 1. Anyone who was at the Triangle Oasis Restaurant on June 11 from 6 p.m. to 8:30 p.m. should monitor symptoms until July 3, while anyone who was at the Steinbach Church of God on June 1 between 9:45 a.m. and 2 p.m. should monitor symptoms until June 23. Public Health also asks those who were in these locations during these times to check their immunization records and ensure they are up to date with the measles vaccine (MMR or MMRV). The province also recommends that people who were exposed in these locations and born in 1970 or later, and have never received a measles vaccine or had a measles infection, get the measles vaccine. Measles is highly infectious and spreads through droplets in the air formed when coughing or sneezing. An infected person can spread the virus from four days before the rash appears until four days after that. Symptoms generally appear seven to 21 days after exposure, and may include a fever, runny nose, drowsiness and red eyes. Small white spots can also appear on the inside of the mouth or throat, the province said. If symptoms develop, people who may have been exposed are advised to isolate at home and contact their health-care provider. The province also stressed that immunization is the "only means of protecting people from contracting measles." The most recent data from the province, which was updated on June 7, says there have been 98 confirmed cases of measles in Manitoba this year, as well as eight probable cases. The province is expected to release another measles update on Wednesday.
