With decades of experience in oncology, I bring deep clinical knowledge and a commitment to clarity for legal professionals handling female cancer cases. As a cancer data specialist, my background allows me to bridge the gap between intricate medical evidence and the strategic needs of your litigation. I am dedicated to providing reliable, impartial expertise that supports your case outcomes with accuracy and insight.

I am Tiffany Troso-sandoval, founder of Second Look Oncology. Over the past 25 years, I have specialised in medical oncology with a focus on breast and gynaecologic cancers at major cancer centres, including Memorial Sloan Kettering. I understand the anxieties that legal teams face when cases hinge on medical details only an expert can interpret. Throughout my career, I have worked with thousands of patients and collaborated with multidisciplinary teams, sharpening my ability to communicate complex information with clarity. I have served as an expert witness and provided consultancy for law firms, insurance companies, and in-house legal teams seeking objective, independent opinions. My approach ensures case materials are handled confidentially and analysed thoroughly against the latest evidence. I am recognised for my commitment to integrity and for producing clear, concise reports that help non-medical audiences understand causation, liability, and treatment implications. I believe an effective expert doesn't just know the science but also knows how to teach it. Alongside my clinical leadership, I host a podcast and publish on women's cancer care to further education and patient advocacy. My goal at Second Look Oncology is to give lawyers the medical clarity and confidence they need to achieve fair and just outcomes. Working together, I can support your litigation with the same level of care and rigour I bring to my patients.

An informed oncology consultant bridges the gap, preparing courtroom ready materials and supporting your team with plain language briefs.
