What is Predisposing cause for Ca. stomach are except ? and explain in detail?
Answer 'b' i.e. Hyperplastic polyp Of the given options, hyperplastic polyp carries the least risk. In fact it carries a very small risk (< 2%) Note that if we follow strictly to the terminolgoy mentioned in Maingots & Schwaz, none of the given options are Predisposing factors; all these are premalignant condition.
