Gene therapy prevents/treats diseases. Scientists can modify cells inside and outside the body.

What Is Gene Therapy? How Does It Work? 

# data[].attributes.body
The genetic information isn't directly inserted into the cell. It is delivered by a vector. Vectors have the ability to remove the disease.

# data[].attributes.body
The transferred genetic material changes how proteins are produced. Gene therapy is being treated to patients with rare or life-threatening diseases, that are caused by genetic mutations from the parents.

# data[].attributes.body
Viruses are often used as vectors because they have the ability to spread genetic information if modified without  infectious disease. Scientists/researchers often use adeno-associated viruses (AAV) as vectors because they have a low chance of spreading an infectious disease.

Gene therapy is targeted towards treating cancer. The most common types of vectors are viral, plasmid, and bacteria.

There are many challenges to gene therapy including costs, issues due to technology, and skilled workers.

The risks of gene therapy include organ failure,  cell damage, and possibility of a tumor. Your body may react to the new viruses unexpectedly and cause inflammation possibly leading to organ failure.  Introduced into the body the virus may return to its ability to cause infectious disease. If new genetic material entered the wrong part of the body, it may lead to the creation of a tumor.
