Asana (Yoga Postures)

Mind-Body

Clinical trials specifically in cancer patients

strong evidenceWidely Available

Asana — the physical posture practice of yoga — is one of the most well-researched complementary therapies in oncology. Unlike general exercise, Asana practice integrates breath, mindful awareness, and precise body positioning to create a practice that simultaneously addresses the physical, neurological, and emotional dimensions of cancer recovery. Multiple systematic reviews and meta-analyses confirm that regular Asana practice significantly reduces cancer-related fatigue, improves sleep quality, decreases anxiety and depression, improves flexibility and strength, and enhances overall quality of life during and after treatment. Iyengar yoga, Restorative yoga, and Yoga Nidra are the most widely offered styles in cancer care settings, with props used to adapt postures for all bodies and treatment phases. Major cancer centres including MD Anderson and Memorial Sloan Kettering now offer dedicated oncology yoga programmes.

How It Works

Asana works through multiple complementary mechanisms: (1) Physical — activates the musculoskeletal system, improves circulation and lymphatic drainage, reduces muscle wasting from treatment, and supports bone density; (2) Neurological — activates the parasympathetic nervous system through breath coordination and slow movement, reducing cortisol and inflammatory cytokines; (3) Psychological — cultivates interoceptive awareness (the ability to sense the inner body), which has been shown to reduce pain catastrophising, anxiety, and depression; (4) Endocrine — reduces insulin resistance, regulates stress hormones, and may positively influence immune cell activity. For lymphoedema specifically, gentle arm-opening postures combined with deep breathing create a pump action that supports lymphatic flow.

What a Session Looks Like

Classes are typically 60—75 minutes. In cancer care, classes are offered in person at integrative medicine centres, hospices, and community yoga studios, as well as online. Oncology-specific yoga programmes (such as those by Tari Prinster's Yoga4Cancer or the IAYT-certified oncology yoga training) adapt postures to avoid compression over surgical sites, port sites, and areas of bone metastasis. Props (blocks, blankets, bolsters, straps) are used extensively. Individual sessions with an oncology yoga teacher are ideal when starting out. Home practice is encouraged — even 15—20 minutes of gentle Asana daily shows measurable benefit.

Cautions & Considerations

Always inform the yoga teacher of your cancer diagnosis, treatment phase, surgical history, and any bone metastases before starting
Avoid inversions (headstands, shoulder stands) if there are brain, bone, or spinal metastases or if you have an ostomy or port
Avoid deep twists or strong abdominal engagement post-abdominal surgery — allow adequate healing time
For lymphoedema: avoid tight elastic bands on the affected limb; practice in a cool room; wear compression garments if advised
Hot yoga (Bikram) is generally not suitable during active cancer treatment due to heat stress and immune compromise
Choose an oncology yoga-certified teacher (Yoga4Cancer, IAYT Oncology Yoga) for the safest practice
