my husband had some tests done due to a hiatus hernia which found some enlarged lymph nodes, following a biopsy these were found to have colorectal cancer cells. He is 64 years old and fit and healthy but we have been given a stage IV diagnosis. I do not understand this as there is no primary and it is just in these lymph nodes. He is due to start chemotherapy after christmas but we dont know when or what type yet. I am so scared of losing him i just cry and i dont want to upset him more.
