Thank you for letting me join this discussion. We have recently discovered that my husband’s birth father died from colon cancer, one year after diagnosis. My husband had stage 2 colon cancer 12 years ago, successfully treated by surgery and chemotherapy. Last year my 41 year old son was diagnosed with Crohn’s disease. The discovery about the grandfather’s cancer only came yesterday. I have 3 sons - two 41 year olds and one 44 year old. With two previous close generations before having had it, I am concerned about the hereditary factor. I am particularly concerned about my son with Crohn’s. Also, I don’t know if this is relevant but my mother, their maternal grandmother, had coeliac disease. Obviously my son with Crohn’s has recently undergone colonoscopies but should all three have screening. I realise they are underage for automatic screening. My husband was 68 when he had it. The grandfather was 78 and died one year after diagnosis. Thank you in advance
