This intervention group consists of multi-component modules developed to help individuals with breast cancer adopt a healthy lifestyle and improve their quality of life. The sessions are based on the 'Do Live Well' model, Kolb's Experiential Learning Theory, and CBT-based problem-solving skills.

Patients in the control group will continue conventional medical treatments, occupational therapy and physiotherapy sessions.

The sessions are based on the 'Do Live Well' model, Kolb's Experiential Learning Theory, and CBT-based problem-solving skills.

Introduction to the Reborn Lifestyle: Core principles of the Reborn Program for building a healthy lifestyle during and after breast cancer.

Physical Activity: The role of physical activity during treatment and exercises to boost energy levels.

Fatigue Management: Scientific methods for managing fatigue during and after treatment.

Pain Management: Effective techniques to reduce pain and improve quality of life.

Mental Health Burden: Strategies to alleviate mental health burdens and cope with stress.

Quality Sleep: Practical methods to improve sleep patterns and achieve quality rest.

Preventive Rehabilitation Approaches: Essential rehabilitation strategies to protect health and reduce recurrence risk.

The study will be conducted online, with evaluations and sessions via Zoom before and after the 12-week modules.

An adjunct to the EORTC QLQ-C30, this scale assesses breast cancer-specific symptoms and treatment-related side effects. It includes subscales for body image, sexual function, and treatment side effects, rated on a 4-point Likert scale. The Turkish version was adapted by Demirci et al. in 2011.

Developed by Borg in 1970, this unidirectional scale (0-10) measures the effort exerted during physical exercise, particularly in assessing dyspnea severity. Participants rate their dyspnea over the past week, with "0" indicating no shortness of breath and "10" indicating severe shortness of breath.

This test measures leg strength and endurance by counting how many times a participant can sit and stand from a chair within 30 seconds. A score of fewer than 10 sit-ups indicates lower extremity weakness. The Turkish validity and reliability were established by Demir and Öztürk in 2020.

The CFS, developed by Okuyama et al. (2000) and validated in Turkish by Şahin et al. (2018), evaluates fatigue in individuals with cancer across three domains: physical, emotional, and cognitive. The scale consists of 15 items, rated on a Likert scale from 1 (not at all) to 5 (very much).

Developed by Melzack in the 1970s and validated in Turkish by Kuguoglu et al. (2003), the MPQ assesses the quality and intensity of pain through four sections, including sensory and perceptual dimensions. Scores range from 0 to 112, with higher scores indicating more severe pain.

This 30-item scale assesses the quality of life in cancer patients across three domains: global health, functional, and symptoms. Higher scores in functional and general health indicate better well-being, while higher symptom scores indicate more severe issues.
