Hatha yoga will be practiced twice a week for 10 weeks

This group will not have any intervention.

Each class started with a check-in period during which any questions or concerns could be raised, after which the patients were given 5 minutes for seated meditation and 10 minutes for Shavasana (lying down in a restorative position).

The following poses were instructed during the course: standing poses with mountain pose (tadasana), chair pose (utkatasana), extended triangle pose (utthita trikonasana), extended side angle pose (utthita parshvakonasana), warrior 1 (virabhadrasana 1), warrior 2 (virabhadrasana 2) and tree pose (vrikshasana). The intervention was applied twice a week for 10 weeks.

Phase angle was evaluated with a Tanita body composition monitor (Tanita Corp., Tokyo, Japan). Electrodes are placed on both feet and both hands that send electrical signals from the body to a single independent unit. Voltages are measured at the top of the thumbs on both hands and both heels. A high-frequency electric current (90μA at 50 kHz) is applied, and the Resistance (R) and Reactance (xc) values are measured between the hands and feet. Internal software calculates the phase angle based on the following formula: Phase angle (PhA) = Reactance (xc) / Resistance (R) * (180 / π)

The European Organization for Research and Treatment of Cancer Quality of life (EORTC QLQ-C30) questionnaire; This 30-question survey is conducted to evaluate QoL in patients with breast cancer and assesses any symptoms that occurred in the previous two weeks. The questionnaires are divided into three scales: global health scale (GHS), functional scale (FS), and symptom scale (SS). High scores in the functional and global health scales indicate a good QoL, while high scores on the symptom scale point to a high level of problems
