May be adequate, but depending If you have breastfed, otherwise the possibility of strias is high when you put under high tension your skin envelope. 
I see in the photo actually a broad thorax, but your Surgeon according with the measures must decide the best volume. Always the decision depends too if the implant is placed under the muscle or subglandular.
the breast augmentation is not a matter of inserting a "silicon bag", it must be the state of the art considering several factors.

I see more an hypertrophic and pigmented scar plus dog ear 
I would recomend it scar revision.
In order TO preventing after, botox at 10 days. This will prevent it For an hypertrophic recurrence.

First of all I see assimetric breast. The nipple of the right one is looking outside, the left one is in central position. You need a personal consultation in order to take several Measures. 
The size Will depend On the wide and height of your breast, plus skin elasticity. 
The type of the implants Will depend On what are your expectations. 
There are a lot to do in the surgical room to get good results. It is not a matter of make and incision and introduce an implant. 

Honesty speaking, even that brain has power, but not in this field. This is a good joke from the people who write this articles, and the worst is the people who believe in. 
There are no scientific evidence to this concern, orherwise they would have a lot of patients seeking breast enlargment!
