2019-04-17 · Women diagnosed with stage 3 first breast cancer appeared at significantly higher risk for contralateral breast cancer than women diagnosed with stage 1 or stage 2 first breast cancer (HR = 1.48; 2016-02-01 · There is no apparent increase in risk of developing a contralateral breast cancer according to the primary cancer histology either IDC or ILC. Standard mammographic follow-up does not need to take account of original tumour pathology. The fourth and final study investigates mammographic density as a risk factor for contralateral breast cancer, studying both mammographic density at diagnosis of the first cancer and changes in density following the first cancer. We find no effect on the risk of contralateral breast cancer by mammographic density at the time of diagnosis of the first cancer; however, there is a significant risk decrease for patients who experience a decrease in breast density during follow-up after the first Relative Risk (RR) of the Development of Contralateral Breast Cancer among Women Exposed to Various Doses of Radiation, According to Age at Exposure and Time after Exposure.* Contralateral breast cancer is the most common second cancer in women with primary breast cancer. With increasing cure rates comes increasing concern about their long-term health. Radiation Epidemiology Branch (REB) investigators and collaborators from the Kaiser health maintenance organization have developed a retrospective cohort of about 7,000 breast cancer patients diagnosed since 1991. Ji, J & Hemminki, K 2007, ' Risk for contralateral breast cancers in a population covered by mammography: Effects of family history, age at diagnosis and histology ', Breast Cancer Research and Treatment, vol.
All women ≥ 18 years of age with unilateral breast cancer who underwent multigene panel testing between January 1, 2014 and Bottom Line: Women with BRCA1 or BRCA2 mutations who underwent adjuvant tamoxifen for breast cancer have a reduced risk of contralateral (other side) breast cancer. The Study: Investigators used the International BRCA1 and BRCA2 Carrier Cohort Study, the Kathleen Cunningham Foundation Consortium for Research into Familial Breast Cancer, and the Breast Cancer Family Registry to identify women 2021-03-31 · A multicenter, individually-matched case-control study was performed to explore the relationship between radiation therapy (RT), smoking, and risk of contralateral breast cancer (CBC). Researchers enrolled 1,521 CBC cases and 2,212 controls with unilateral breast cancer; first invasive breast cancer was diagnosed in all between 1985–2008 at age < 55 years. Prophylactic contralateral (CLT) breast radiotherapy was associated with significantly fewer and delayed cases of breast cancer in women having standard therapy for their ipsilateral BRCA mutation-associated breast cancers in a study from Israel reported in a poster session at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting . For each of the 3 analyses (breast cancer risk, contralateral breast cancer risk, and ovarian cancer risk), we defined a different group eligible at baseline .
Bottom Line: Women with BRCA1 or BRCA2 mutations who underwent adjuvant tamoxifen for breast cancer have a reduced risk of contralateral (other side) breast cancer. The Study: Investigators used the International BRCA1 and BRCA2 Carrier Cohort Study, the Kathleen Cunningham Foundation Consortium for Research into Familial Breast Cancer, and the Breast Cancer Family Registry to identify women
With a special focus on contralateral breast cancer. Cancergenetisk utredning vid misstänkt bröstcancerrisk, mutationsscreening . study of the risk of second primary contralateral breast cancer or surgery to bone, hypercalcaemia) in patients with breast cancer with bone metastases or hypercalcaemia where the benefit outweighs the potential risk (see 4.4 Fractures are often bilateral; therefore the contralateral femur should be.
This tool cannot accurately calculate risk for women with a medical history of breast cancer, DCIS or LCIS. Other tools may be more appropriate for women with known mutations in either the BRCA1 or BRCA2 gene, or other hereditary syndromes associated with higher risks of breast cancer. See Other Risk Assessment Tools for more information.

However, patients with breast cancer have an increased risk of developing a new primary breast cancer in the contralateral breast. Family history of breast cancer, early age at diagnosis, characteristics of the first primary (for example lobular histology and stage) and mutations in specific genes, including BRCA1, BRCA2 and CHEK2, are Contralateral breast cancer risks have been shown to be reduced by adjuvant treatment of the first cancer. 24,25 BRCA2 carriers are more likely to develop estrogen receptor–positive cancers, so their lower contralateral breast cancer risk estimates may in part be due to greater use of endocrine therapy.

[Epub ahead of print] The incidence of contralateral prophylactic mastectomy (CPM) has increased among women with breast cancer, despite uncertain survival benefit and a declining incidence of contralateral breast cancer (CBC). Contralateral breast cancer is of etiological interest because there may be shared risk factors between the first and second primaries (e.g., a family history of breast cancer), whereas other risk factors can be unique to the second primary (e.g., radiotherapy). However, patients with breast cancer have an increased risk of developing a new primary breast cancer in the contralateral breast. Breast cancer survivors are at risk for contralateral breast cancer (CBC), with the consequent burden of further treatment and potentially less favorable prognosis.
Previous research has shown that polygenic risk scores (PRSs) can be used to stratify women according to their risk of developing primary invasive breast cancer. This study aimed to evaluate the association between a recently validated PRS of 313 germline variants (PRS313) and contralateral breast cancer (CBC) risk. Three tools are currently available to predict the risk of contralateral breast cancer (CBC). We aimed to compare the performance of the Manchester formula, CBCrisk, and PredictCBC in patients with invasive breast cancer (BC).

By multivariable Cox regression, endocrine therapy was associated with lower CBC risk (hazard ratio 0.57, p = 0.03). Conclusions: Although CBC risk is declining in the US from 1992-2015, survivors have approximately twice the risk of an incident breast cancer (in the contralateral breast) compared to the general population.
