Tahania Ahmad


Post doctoral research Fellow



I joined the Centre for Cancer Screening, Prevention and Early Diagnosis as a post-doctoral research fellow in January 2024. At present, my research endeavours primarily revolve around a breast cancer project, wherein I am investigating the efficacy of serum estradiol and other hormonal markers in identifying women who are most likely to respond to preventive treatment for breast cancer. Additionally, my focus extends to understanding the risk factors associated with Oesophageal cancers and elucidating variations across different countries.

I am in the final stage of my PhD on “Multimorbidity in cancer survivors in the UK”, particularly focusing on breast, prostate, bladder, colorectal, cervical and lung cancer survivors. I compared the prevalence and incidence of multimorbidity in cancer survivors with non-cancer patients over a ten year time period using CPRD and HES data. Furthermore, I explored ethnic and socio-economic disparities in multimorbidity among cancer survivors, alongside analysis of primary care utilization and hospital admissions within this demographic. Previously, I worked on as a medical statistician at Pragmatic Care Clinical Trials Unit (PCTU) QMUL and Barts NHS. I hold a Master’s degree in Public Health specialising in Epidemiology from Imperial College, London and a certification on “Advanced Statistical Methods in Epidemiology” from LSHTM.


Research Interests:

  • Cancer prevention and screening
  • Longitudinal analysis of multimorbidity in cancer survivors
  • Analysis of observational studies and cohort studies
  • Clinical trials
