“Can anxiety attacks be stopped?”

Definitely! This would be a fantastic reason to work with a therapist.

Anxiety attacks are different from individual to individual. Do the attacks occur in specific contexts or do they occur across contexts. Context specific attacks disappear when one leaves the context trigger ( what occurs / associated with that specific context). General attacks are not necessarily associated with specific contexts, but, can grow worse in specific contexts, and, are more characteristic of individuals who experience heightened nervousness most of the time. Treatment and / or counter-conditioning can help. Once the causal factors are identified, change in anxiety attacks can be approached based upon the identified causative factors.
