evidence: However, naturopath Barbara O’Neill claimed that mammograms actually contribute to cancer rather than prevent it. In an interview posted on TikTok in May 2024, O’Neill was asked about mammograms and stated that "it’s pushed to prevent and it does not prevent". She further added that repeated mammograms contribute to breast cancer because of the radiation sent through the breast and because of breast tissue damage that allegedly occurs during the test. This video generated 1.6 million views on TikTok at the time of writing. It was also posted on Facebook. [...] O’Neill’s claim that mammograms don’t prevent cancer is also inaccurate. Indeed, regular screening allows early detection of cancer, and early diagnosis is associated with an increased chance of survival. According to Cancer Research UK, all women diagnosed at an early cancer stage will survive for at least five years. This statistic falls to three out of ten women if the diagnosis is made at a late cancer stage. [...] Periodic mammography screening doesn’t cause nor contribute to cancer growth, contrary to Barbara O’Neill’s claim. In fact, regular mammograms do the opposite. By allowing for early detection of cancer, mammograms improve the success of cancer treatment and increase the chance of survival.
