Disease and genetic inheritance

Today we are going to comment on the Best Doctors Blog about the close relationship between some diseases and the genetic inheritance that parents pass on to their children through their genes.

It is safe to say that genes are the cornerstone of genetic inheritance, in so far as they contain our DNA, which in turn determines the instructions for making proteins in our body. Proteins carry out most of the functions within our cells: building structures, moving molecules and decomposing different types of toxins – to name but a few activities.

What is DNA? Deoxyribonucleic acid (abbreviated as DNA) is a nucleic acid whose content contains the genetic instructions used in the development of all living organisms that we know of. If we address the nature of the deoxyribonucleic acid molecule, we will find that its natural purpose is the long-term conservation of genetic information. As far as its structure is concerned, DNA takes the form of a double helix in which the information is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T). Now that we have learnt a little more about what Read more

Helping to prevent colon cancer with just a blood sample

Once again, the Best Doctors blog keeps you posted on an interesting and promising scientific advance for many patients that could suffer from colon cancer in the future.

This time, it is a research project led by a Spanish biologist, Luis Gómez, who has developed a new system for the early detection of malignant polyps that end up turning into this much feared form of cancer.

Let’s talk numbers  According to the American Cancer Society we’re talking about more than 102,000 cases in the U.S. alone in 2013. In terms of Continental Europe, the numbers for countries such as Spain stand at around 27,000 cases per year.  If we look at things in more detail, it is calculated that 6% of the population will suffer from this type of cancer at some point in their life. One has to take into consideration that the risk of contracting colon cancer increases if a relative has suffered from it in the past. So if there are many cases in your Read more
