Objective: Easier access and increased awareness results in more referral for genetic testing for hereditary breast cancer in healthy at-risk women and breast cancer patients. To investigate the psychological impact of genetic testing on breast cancer patients, literature pertaining to this group was reviewed.
Method: Medline and PsychInfo databases were searched over the period 1995-2004 for studies aimed at breast cancer patients referred for genetic testing. Qualitative and quantitative psychological outcome measures were identified.
Results: Eight papers were identified focusing on women affected by breast cancer and undergoing genetic counseling and DNA testing.
Conclusion: Genetic testing does not lead to an increase in psychological distress in breast cancer patients. However, a recent breast cancer diagnosis adds to general and cancer-specific distress prior to genetic counseling and after DNA test disclosure.
Practice Implications: Clinicians need to be aware of possible high psychological distress and additional counseling needs of recently diagnosed breast cancer patients taking part in genetic testing. Further research should focus on patients who decline genetic counseling or receive an inconclusive test result, including age upon and time since diagnosis.

Herein, fluorescent calcium carbonate nanoclusters encapsulated with methotrexate (Mtx) and surface functionalized with chitosan (25 nm) (@Calmat) have been developed for the imaging and treatment of triple-negative breast cancer (TNBC). These biocompatible, pH-sensitive nanoparticles demonstrate significant potential for targeted therapy and diagnostic applications. The efficacy of nanoparticles (NPs) was evaluated in MDA-MB-231 TNBC cell lines.

In this work, we evaluated the anticancer activity of compounds 1 (mononuclear) and 2 (dinuclear) copper(II) coordination compounds derived from the ligand 5-methylsalicylaldehyde 2-furoyl hydrazone (H2L) over MDA-MB-231 Triple-negative breast cancer (TNBC) cells, and compared their activities with that of a newly synthesized, protonated, dinuclear analogue of 2 (complex 3). Here, we report the synthesis of compound 3 and it has been characterized in the solid state (X-ray diffraction, FTIR) and in solution (EPR, UV-Vis, ESI) as well as its electrochemical profile. Complexes 1-3 impaired cell viability from 0.

Importance: Transportation insecurity and lack of social support are 2 understudied social determinants of health that contribute to excess morbidity, mortality, and acute health care utilization. However, whether and how these social determinants of health are associated with cancer screening has not been determined and has implications for preventive care.
Objective: To determine whether transportation insecurity or social support are associated with screening adherence for colorectal, breast, and cervical cancer.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.
