Sun Health Explainer: What is cancer?

Yang Wang, a researcher in the Department of Medical Biochemistry and Biophysics, said: "We now need to investigate whether this works in more advanced cancer models that more closely resemble the real human disease.The scientists previously developed structures that can organise so-called death receptors on the surface of cells, leading to cell death.

Now, they have used the technique to create a ‘kill switch’ that is activated under the right conditions, sparing healthy cells."We have managed to hide the weapon in such a way that it can only be exposed in the environment found in and around a solid tumour," Prof Högberg said. Each year around 385,000 people are diagnosed and 167,000 lives are lost to the disease in the UK . . . and experts have warned of an alarming new surge in the young.Perhaps the most exciting new avenue of research is tailoring medicine to treat a patient’s cancer based on their own tumour’s genetic make-up.

Some 10,000 patients in England are set to get their very own disease-busting jab by 2030, through the NHS Cancer Vaccine Launch Pad.Dubbed the “biggest breakthrough since chemo”, immunotherapy harnesses the power of the immune system to fight cancer. “Antibodies are effective alone, but where they are most effective is in combination with another type of immunotherapy.”It has been approved for treating several cancers on the NHS, including melanoma, cervical, breast and lung cancer. But its use could be extended to bowel cancer.These work more precisely to stop cancer cells from dividing and growing, while limiting damage to healthy cells – and their uses are expanding.
