This is the cancer with the highest incidence in Spain considering both sexes and it is very common beyond 50 years of age.
The risk of developing this type of cancer depends on many factors such as age, genetic and family history, occasional polyps that become malignant, familial adenomatous polyposis, Lynch syndrome, inflammatory bowel diseases, diet and lifestyle. Diagnostic tests may include tests for blood in the stool, colonoscopy, and imaging studies.
Treatment of rectal cancer with radiation therapy along with chemotherapy can be administered before surgery to reduce the risk of local recurrence, but can also be administered after surgery. With techniques such as Intensity Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT) combined with Image Guided Radiation Therapy (IGRT), the daily positioning of patients can be verified and thus a more precise treatment can be assured. In this way, it is possible to treat the tumour and reduce the dose to the surrounding healthy organs, reducing unwanted side effects. The GCCC 360 Centre of Oncological Excellence is pioneer in magnetic resonance planning in pelvic tumours, thus helping to better define tumours and achieving greater precision. In many cases, it is also possible to apply hypofractionation, which consists of administering high doses of radiation with maximum precision and in fewer sessions, just 5 days in this case.
