Treatments and the cancers he treats
Radiotherapy, chemotherapy, immunotherapy and other targeted treatments, planned and overseen by one consultant.
MR-Linac SABR
Radiotherapy given on a machine with an MRI scanner built in. The scanner shows the tumour and the healthy tissue around it while you are being treated, so the dose can be aimed tightly and the plan adjusted on the day.
Delivered at GenesisCare centres in London, Guildford and Oxford, planned and overseen by Dr Harinarayanan.

Before you get in touch
Is MR-Linac SABR available on the NHS?
Generally not. The one exception is GenesisCare Oxford, which has a limited NHS contract and treats a small number of patients there on a compassionate basis. Everywhere else, access is private. He will tell you plainly whether an NHS route exists for you.
Do I need a referral?
Most patients come from their surgeon, oncologist or multidisciplinary team, and a referral letter with your scans makes the first appointment more useful. Insured patients need a referral for their insurer. Self-pay patients seeking a second opinion can contact the practice directly.
What does a consultation cost?
A new consultation is £275 and a follow-up £200. Scans, tests and treatment are billed by the hospital or GenesisCare, and you will know what to expect before anything is booked.
Where would I be treated?
Consultations at Spire Southampton or Solent Private Suites, University Hospital of Southampton, or by video call from anywhere in the UK. Radiotherapy and chemotherapy at GenesisCare Southampton. MR-Linac SABR at GenesisCare's centres at Cromwell Hospital in London, in Guildford or in Oxford, where the machines are.
