The correct answer is "El cáncer es una enfermedad grave."

El cáncer es una enfermedad grave.

Explanation:

Cancer is the name given to a set of related diseases. In all types of cancer, some of the body's cells begin to divide without stopping and spread to surrounding tissues.

It can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When normal cells get old or damaged, they die, and new cells replace them.

However, in cancer, this orderly process is out of control. As cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed. These additional cells can divide without interruption and can form masses called tumors.

Many cancers form solid tumors, which are masses of tissue. Blood cancers, such as leukemia, generally do not form solid tumors.

Cancerous tumors are malignant, which means they can spread to nearby tissues or invade them. In addition, as these tumors grow, some cancer cells can break away and move to distant parts of the body through the circulatory system or lymphatic system and form new tumors away from the original tumor.

Unlike malignant tumors, benign tumors do not spread to nearby tissues and do not invade them. However, sometimes benign tumors can be quite large. When removed, they usually do not grow back, while malignant tumors do sometimes grow back. Unlike most benign tumors in other parts of the body, benign brain tumors can be life-threatening.
