Elements <img>
are by default inline-block
i.e., you can apply block styles (such as width, height, border) and they follow the text flow.
Assuming that the image already in the desired size or proportion (in your case 150px x x 150px), you do not need "hacks" using position
, margin
or transform
Behold:
.img-circle {
border-radius: 50%;
width: 150px;
height: 150px;
}
.text-center {
text-align: center;
}
<div id="conteudo"><!-- Inicio Conteudo -->
<h1>Sobre Edson Luiz</h1>
<div class="text-center ">
<img src="https://dummyimage.com/150x150/000/fff.jpg" class="img-circle">
</div>
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

Remember that in this case it would also be interesting to center the title, including a css rule ". title { text-align: center; }" and changing the title to "<H1 class="title">About Edson Luiz</H1>".
