AI for Early Cancer Detection

I'm seeking a machine learning expert to develop an AI model for analyzing circulating tumor DNA (ctDNA) to detect cancer early. The goal is to achieve detection accuracy between 80% and 90%.

Key Requirements:
- Develop an AI model for ctDNA analysis
- Target early detection of multiple cancers
- Aim for 80-90% accuracy

Ideal Skills and Experience:
- Expertise in machine learning and AI
- Experience with genomic data analysis
- Background in oncology or related fields
- Strong programming skills (Python, R, etc.)
- Ability to work without an existing dataset

Please provide a detailed approach, timeline, and any preliminary research you might conduct.
