My son has just had surgery for colon cancer,he’s 38 due to a gene called Lynch syndrome,on his fathers side.Everything went very well and 3 weeks on he is excercising and recovering well,he was given a less than 10% chance of chemo,unfortunately he is in that less than 10% he is waiting for appt with oncologist to discuss his chemo treatment,we are terrified,he had 20 lymph nodes removed at surgery 3 have come back cancerous.Any info on similar treatment would be so helpful,feel like we are drowning.Thank you.
