Husband

Hi
Looking if anyone has had a diagnosis of this particular cancer signet cell gastric adenocarcioma
My husband had no symptoms just off food for 2 to 3 weeks was admitted to hospital in late September 2022 got a diagnosis of stage 4 signet cell gastric cancer 12 days later and died 12 days after that seemly this cancer shows no symptoms till your stage 4 .
It has been so hard to accept that someone can be taken so suddenly really on the flip of a coin .
Have looked for information or support group but their does not seem to be any.
We as a family are heartbroken at how sudden the onset was and are looking
for anyone who has had this or has information.
