Stomach cancer may have a genetic compound, or could just be bad luck. Cancer is when cells start to multiply excessively, but do not, like normal cells, die off when they have reached a specific age, So they just keep growing. Cancer, with the exception of very very few, is not contagious. Stomach cancer is not contagious.
