Understanding cancer

According to the Ministry of Health, cancer is the name given to a group of more than a hundred diseases that involve the irregular growth of cells that invade tissues and organs. These cells divide rapidly and tend to be very aggressive and uncontrollable, causing tumors to form, which can spread to other areas of the body.

The disease arises from a genetic mutation, that is, from a change in the DNA of the cell, which begins to receive incorrect instructions for its activity. When conditions start in epithelial tissues, such as the skin or mucous membranes, they are called cancers. If the starting point is connective tissue, such as bone, muscle, or cartilage, they are called sarcomas.

Cancer does not have a single cause. According to the Ministry, there are several external causes (found in the environment) and internal causes (such as hormones, immune conditions, and genetic mutations), and between 80% and 90% of cases are linked to external causes. Self-induced changes in environment, habits and lifestyle can increase risks.
