Rectal Cancer diagnosis at 40, Stoma surgery decision

After spending the most of 2025 with bloating and frequent trips to the GP I was told I was constipated, or having a flare up of IBS. 
Fast forward to  October, just before my 40th birthday a positive FIT test led to finally getting a colonoscopy, outcome - 20mm ulcer with suspected Cancerous cells. MRI CT and further tests later here we are at a full diagnosis of Squamous Cell Carcinoma, potentially looking like its affected Lymph nodes (awaiting PET scan results) planned treatment suggested Chemotherapy and Radiotherapy. 
The question have been left with is before chemotherapy and radiotherapy do I have a stoma fitted, or begin treatment and potentially have to stop if stoma is needed later. I know everyone’s different but appreciate anyones feedback, first meeting with oncology on 12th Dec. 

  • Hello Kasza85 and thank you for your post.

    I am sorry to learn that you have recently been diagnosed with bowel cancer. This must be a difficult time for you.  It is difficult to say whether you will be advised to have a stoma before starting treatment as everyone is treated as an individual. It also depends on the grade and stage of your cancer. 

    For most people the first step is usually chemotherapy and radiotherapy together.  A stoma is usually only fitted before treatment depending on where in the bowel the tumour is situated and if your having symptoms such as pain or trouble controlling your bowels.  If you’re not having these issues, doctors usually try treatment first without a stoma. Your hospital specialist will explain what’s best for you.

    I hope you know more about your treatment options soon, and  your treatment goes without any issues.
