Knowledge: Cancer can be cured if chemotherapy and surgery is possible. However, lactose intolerance cannot because there is not enough study.

Conversation:
Do you know anything about being lactose intolerant?
Well, I know that it is a condition that happens when people can't digest lactose very well
Yes -- all dairy products make you have gas or indigestion; however, there are things you can do about it.
Yeah, some symptoms from it can be gas, diarrhea, nausea and even pain in the abdomen
That sounds bad, does it couse any damage to the gastrointestinal tract?
Actually no, it doesn't cause any damage to this tract.
Interesting. Is it possible to get it cured?

Response: Hmm sadly no. Lactose intolerance cannot be cured because there is not enough study.
