    Press Programme

    • "Bowel cancer data reinforce need to reduce unnecessary antibiotic use"
      Doctors and patients are being advised to reduce unnecessary antibiotic use following new data suggesting that these medicines may increase the risk of cancer of the large intestine (colon), especially in people under 50 years.

    • "Poorer survival in obese colorectal cancer patients possibly linked to lower chemotherapy doses"
      Obese patients with colorectal cancer receive lower cumulative relative doses of adjuvant chemotherapy than non-obese patients. Further findings showed that cumulative relative chemotherapy dose was associated with survival so may explain the poorer survival that has been seen in obese patients receiving adjuvant chemotherapy for colorectal cancer.
