Tumour Perforation

I was diagnosed with stage 3 bowel cancer last September and have subsequently had 5 cycles of FOLFOX chemotherapy.

I was MRI/CT scanned initially following diagnosis and then rescanned after my 4th cycle of chemo which showed the tumour has perforated.

I’ve since needed a colostomy to bypass the tumour pending surgery. I was due to have 5 weeks of chemotherapy and radiotherapy before surgery but this has now been cancelled due to the perforation. I’ve now been given 2 options for surgery to remove the tumour which I’m considering. 

Has anyone else had any experience of a perforated tumour and if so what surgery options were you given?

Many thanks
