A study published Jan 2026 in Sociology of Health & Illness offers insights into a growing trend — thousands of women diagnosed with ductal carcinoma in situ (DCIS) have joined together in a support group specifically about a diagnosis that includes the word “carcinoma,” but thanks to newer evidence and experts calling for change, the women in the group believe strongly “DCIS is NOT breast cancer,” and does not require breast cancer treatments.
The mindset follows the published research over three decades discussing DCIS as a result of mammography screening which led to an epidemic of “overdiagnosis.” Aggressive “standard-of-care” treatments which follow are believed to be “overtreatment.”
The study abstract states:
“DCIS, or ductal carcinoma in situ—also known as Stage 0 breast cancer—accounts for approximately 20 per cent of new breast cancer cases. Although it is noninvasive, treatment typically mirrors that of invasive cancer. Whether DCIS is overtreated remains controversial, even among medical professionals. This study analyses discussions within a Facebook group of women diagnosed with DCIS who have declined the standard of care (SOC). The findings suggest that these women hold contrasting views on cancer risk compared to their healthcare providers. Although doctors focus on the potential for DCIS to progress to invasive cancer, the women emphasise the higher likelihood of nonprogression. Their considerations of alternative treatments are often dismissed by medical professionals, heightening the stress of an already anxiety‐inducing diagnosis. This online community provides affirmation and support to those who choose holistic approaches to manage their condition. However, rejecting the SOC shifts the responsibility for healing onto the individual. These women must engage in vigilant self‐surveillance, maintain strict healthy lifestyles and uphold an optimistic outlook—demands that require significant physical discipline and emotion work. This case carries important implications for both sociological research and medical practice.”
The group is affiliated with DCIS 411. More info on the DCIS controversies here.
