What is Space Oncology?
Space oncology is an emerging interdisciplinary field that studies how space conditions—particularly microgravity and cosmic radiation—affect cancer cells, tumour growth, treatment response, and cancer-cell adaptation.
Space as a Natural Laboratory
- Provides unique microgravity and radiation environments difficult to replicate on Earth
- Helps researchers understand metastasis, treatment resistance, radiation response, and tissue behaviour
- Supports biomarker discovery and advanced tumour modelling
Research Applications
- Protein crystallisation for drug development
- 3D cell cultures and tumour spheroid formation
- Enhanced drug formulation and testing
- Reduced dependence on animal studies
Rising Cancer Burden in India
- India expected to witness approximately 1.87 million new cancer cases in 2026
- Cancer imposes significant economic burden through:
- High treatment costs
- Income loss during treatment
- Debt and asset depletion
- Caregiver burden
- Growing need for advanced therapeutic models and cost-effective solutions
Effects of Microgravity on Cancer Cells
Cellular Changes
- Cytoskeletal reorganisation
- Altered focal adhesion signalling
- Changes in extracellular matrix interaction
- Modified gene expression patterns
Tumour Behaviour Changes
- Affected cancer cell adhesion, migration, and proliferation
- Altered invasion capabilities
- Formation of multicellular tumour spheroids (3D clusters)
- Changed drug uptake and treatment response
Cancer-Type Specific Effects
- Breast Cancer: Microgravity reduces malignant characteristics by affecting adhesion, migration, and cell-cycle regulation; tumour spheroids become more responsive to specialised therapies
- Gastrointestinal Cancer: Altered progression under microgravity with increased drug sensitivity due to changes in resistance genes and cellular proteins
