Know the Risk Before Cancer Shows Its First Sign

Saltlick Healthcare Pvt Ltd is an independent company shaped by the scientific vision and entrepreneurial leadership of Dr. Raktim Chattopadhyay, PhD, a distinguished scientist, healthcare entrepreneur, and thought leader in oncology and medical nutrition.

Over two decades spent bridging research, translational science, and clinical practice, Dr. Chattopadhyay has built a body of work centered on reshaping how cancer risk, prevention, and care are approached at population scale. That grounding in cancer biology and nutrition science directly informs Saltlick's mission: moving India's cancer-care paradigm from reactive detection to systematic, preventive assessment.

Conventional cancer-care pathways often begin only after symptoms appear. By then, the opportunity for low-burden prevention, closer surveillance, and earlier diagnostic action may already be smaller.

Saltlick Healthcare Pvt Ltd is building a platform designed to act sooner: estimate an individual's probability of developing cancer before symptoms emerge, identify who needs closer attention, and guide each person toward an appropriate prevention or diagnostic pathway.

Saltlick Healthcare Pvt Ltd's approach pairs two things that, on their own, aren't enough: government reach and deployable technology.

This PPP structure is designed to bring proactive risk assessment to people who currently fall outside conventional screening, making prevention and diagnostic follow-up more accessible, systematic, and timely.

Health Voitho works with Saltlick Healthcare Pvt Ltd as its technology partner, building the medical-technology ecosystem that enables the model end to end, from risk-assessment systems and clinical workflows to the connected infrastructure required across thousands of care sites.

This includes the technical and infrastructural foundation for:

• →AI-enabled cancer risk scoring at population scale
• →Hub-and-spoke clinical infrastructure connecting PHCs and district hospitals to specialist care
• →A digital referral backbone that moves a person from risk assessment to the right point of care

The conditions that make this PPP model work in India, including rising lifestyle-driven cancer incidence, low screening penetration, and public health infrastructure that is present but under-leveraged, are not unique to India. They describe a broader set of geographies where a government-partnered, hub-and-spoke approach to cancer risk screening could be adapted rather than rebuilt from scratch.

Guided by WHO's projections on the rising cancer burden across low- and middle-income countries, the geographies that most closely mirror India's starting conditions include:

This is the long-term opportunity Saltlick's model and Health Voitho's technology platform are being built to support.
