Precision cancer care, close to home.
Dr Sathish Harinarayanan is one of a small number of oncologists on the South Coast accredited for MR-Linac SABR, radiotherapy that watches the tumour while it treats it. He specialises in bowel cancer, including treatment that can help suitable patients avoid a permanent stoma.

Radiotherapy, chemotherapy and immunotherapy, planned by one consultant.
Every treatment is delivered through GenesisCare or Spire Hospital Southampton, with consultations also available at Solent Private Suites, University Hospital of Southampton. Dr Harinarayanan plans it, oversees it and sees you throughout.
MR-Linac SABR
MR-Linac SABR is 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 for that day. Dr Sathish Harinarayanan is accredited by GenesisCare UK to deliver it and treats patients on the MR-Linac at three GenesisCare centres: London, Guildford and Oxford.

SABR stands for stereotactic ablative radiotherapy: a short course of very precise, high-dose radiotherapy aimed at a small, well-defined tumour. It is an established treatment across the UK for small cancers and for cancer that has spread to a few places. Dr Harinarayanan uses CT-guided SABR at GenesisCare Southampton and MRI-guided SABR on the MR-Linac at GenesisCare's London, Guildford and Oxford centres.
Read more →Precision radiotherapy, IMRT and VMAT
Radiotherapy uses carefully shaped beams of high-energy X-rays to damage cancer cells so they stop growing. Modern techniques such as IMRT and VMAT shape the dose to the tumour and spare what is around it. Dr Harinarayanan plans and oversees private radiotherapy at GenesisCare Southampton, on the same site as Spire Southampton Hospital, for bowel and rectal cancer and cancer that has come back after earlier treatment.
Read more →Chemotherapy and systemic therapy
Systemic therapy means treatment that travels through the whole body in the bloodstream, rather than being aimed at one spot. Chemotherapy is the best-known kind. Dr Harinarayanan plans chemotherapy and other drug treatments as a consultant clinical oncologist, and they are delivered privately at GenesisCare Southampton, on the same site as Spire Southampton Hospital.
Read more →Immunotherapy and targeted therapy
Immunotherapy helps your own immune system recognise and attack cancer cells. Targeted therapy blocks a specific fault inside cancer cells that helps them grow. Both are systemic therapies, meaning they travel through the bloodstream to reach cancer wherever it is. Dr Harinarayanan uses them for selected bowel cancers, guided by tests on the tumour, and they are delivered privately at GenesisCare Southampton.

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.
