The largest study of the question, 134,435 married Finnish women followed for a median of 17 married years, found no increase in marital breakdown after early breast cancer, with a hazard ratio of 0.96.","summary":"This record exists because one finding travelled much further than the evidence behind it, and a reader who meets it at two in the morning deserves the rest of the picture.\n\nThe study people quote. In 2009, 515 patients who were married at the time of diagnosis, 214 with a malignant primary brain tumour, 193 with a solid tumour without nervous system involvement and 108 with multiple sclerosis, were followed prospectively from enrolment until death or the end of the study. Divorce or separation occurred in 11.6 per cent overall, which the authors noted was similar to published rates. The difference by sex is what was reported: 20.8 per cent when the patient was the woman against 2.9 per cent when the patient was the man, p below 0.001, and female sex was the strongest predictor of separation in each of the three cohorts. The paper also reported that people with brain tumours who separated or divorced were more likely to be admitted to hospital and less likely to join a clinical trial, complete cranial irradiation or die at home.\n\nThe study people do not quote. A Finnish registry cohort followed 134,435 married women for a median of 17.0 married years and compared those diagnosed with early-stage breast cancer against the rest, adjusting for age, socioeconomic status, education, number of children, duration of marriage and earlier marriages, and analysing surgery, chemotherapy, radiotherapy and endocrine therapy separately. The hazard ratio for marital dissolution after a diagnosis was 0.96 (95 per cent confidence interval 0.79 to 1.17). \"Neither the type of surgical procedure nor any of the oncologic treatments was associated with an increase in the risk of divorce.\" Its title is a statement: early-stage breast cancer is not associated with the risk of marital dissolution.\n\nTwo other datasets sit between them. Among 599 women in a Brazilian cohort study who were married or in a common-law relationship at diagnosis, 35 (5.8 per cent) had divorced or separated by two years; public rather than private health cover carried the higher risk (relative risk 3.09), and mastectomy rather than breast-conserving surgery was associated with a higher risk (8.1 against 4.49 per cent, relative risk 1.97). In a Korean survey of 4,366 breast cancer survivors, about 11.1 per 1,000 married survivors divorced after diagnosis, and those who did reported worse quality of life, social functioning and body image and more pain, insomnia, financial difficulty and distress about hair loss.\n\nHow to read that spread. Rates of marital breakdown after cancer are broadly in line with background rates in the general population in the largest and best-controlled studies. The sex difference reported in the 2009 cohort has not been reproduced in a study of comparable size, and the one very large prospective study of women with breast cancer found no excess at all. Whether that means the original finding was specific to the centres and diagnoses studied, or does not generalise, is not settled; what is clear is that it should not be presented to a newly diagnosed woman as a fact about her marriage.\n\nWhat the relationship actually has to carry. The mood data are the more useful part. In the meta-analysis of long-term survivors and their spouses, depression affected 26.7 per cent of the patients and 26.3 per cent of their spouses, and anxiety 28.0 per cent of patients and 40.1 per cent of spouses, neither difference reaching significance but both figures high. The systematic review of fear of recurrence found that carers reported higher fear than the patients. Several distinct problems get called relationship problems: the patient's fatigue and the partner's exhaustion; a change of role from partner to carer, which is covered by the carers record here; sexual difficulty, which has its own record built on the guideline evidence and is the one most often left unmentioned by both the couple and the team; and the fact that each person is often protecting the other from what they are thinking.\n\nWhat helps. The couple-based interventions were pooled in the carers literature rather than separately: psychoeducational, skills training and therapeutic counselling interventions, mostly delivered jointly to patient and carer, had small to medium effects and significantly reduced carer burden, improved coping and self-efficacy and improved aspects of quality of life. The sexual function record in this front carries the guideline recommendation that a member of the care team should raise sexual difficulty and that counselling should be offered to everyone. Nothing here supports the idea that a relationship that ends after cancer failed a test.","status":"established","asOf":"2026-10-02","wikipedia":"https://en.wikipedia.org/wiki/Interpersonal_relationship","links":[{"label":"Early-stage breast cancer is not associated with the risk of marital dissolution in a large prospective study of women (Br J Cancer 2015)","url":"https://doi.org/10.1038/bjc.2015.216"},{"label":"Gender disparity in the rate of partner abandonment in patients with serious medical illness (Cancer 2009)","url":"https://doi.org/10.1002/cncr.24577"},{"label":"The impact of a breast cancer diagnosis on marital outcomes and factors associated with divorce and separation (Rev Bras Ginecol Obstet 2024)","url":"https://doi.org/10.61622/rbgo/2024rbgo60"},{"label":"Divorce after breast cancer diagnosis and its impact on quality of life (Palliat Support Care 2023)","url":"https://doi.org/10.1017/S1478951521001711"},{"label":"Depression and anxiety in long-term cancer survivors compared with spouses and healthy controls: a systematic review and meta-analysis (Lancet Oncol 2013)","url":"https://doi.org/10.1016/S1470-2045(13)70244-4"},{"label":"Fear of cancer recurrence in adult cancer survivors: a systematic review of quantitative studies (J Cancer Surviv 2013)","url":"https://doi.org/10.1007/s11764-013-0272-z"}],"tags":["rejuvenation","survivorship","evidence:moderate","psychosocial"],"related":["carers-breast-cancer-uk","idea-moon-sexual-health-as-toxicity-domain"],"cancers":["breast-hr-positive","tnbc","glioblastoma","prostate","colorectal"],"sections":["rejuvenation","supportive-care"],"technologies":["rejuv-life-carers","rejuv-life-children-of-a-parent-with-cancer","sexual-function-after-cancer","rejuv-mind-anxiety-after-cancer","rejuv-mind-body-image-after-cancer","psycho-oncology"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":["quality-of-life","late-effects"],"trials":[],"people":[],"bottlenecks":["b-survivorship","b-toxicity-qol"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"principle":"A cancer diagnosis loads an existing relationship rather than creating a new one: it adds a caring role, removes income, alters sexual function and sleep, and introduces a shared uncertainty that each person tends to manage by protecting the other from it.
