The chances of breast cancer recurring remain very low when patients are treated with radiotherapy that is tailored to their individual risk following chemotherapy and surgery. These are the findings of a ten-year study presented at the 15^th European Breast Cancer Conference in Barcelona.

Researchers developed a web-based intervention to educate people with cancer about the impact genetic variants can have on their family. It includes education and decision support to help patients feel comfortable communicating genetic testing information to their relatives. The platform also allows patients to invite first- and second-degree relatives to the site. Relatives get information about genetic risk, tools to help them decide if they want to receive genetic testing and access to testing.

Chronic stress may significantly influence the course of cancer by affecting key biological mechanisms involved in tumor progression and immune response. Increasing evidence suggests that prolonged exposure to stress hormones can promote tumor growth, facilitate metastasis, and weaken the body's natural defense systems.

Researchers emphasize that stress is not only a psychological burden but also a physiological factor with measurable effects on cancer development and treatment outcomes. Stress-related processes, including inflammation, hormonal dysregulation, and immune suppression, may contribute to a more aggressive disease course.

These findings highlight the importance of integrating psychological support and stress management into standard oncological care. Addressing chronic stress could become an important complementary strategy in improving patient outcomes and quality of life.
