Cancer is actually a group of diseases in which the body produces an excess of malignant cells (known as cancer or cancerous), with growth and multiplication beyond normal limits and regulations (typical of healthy organisms) .
Cancer is also called malignant tumor or malignant neoplasm. The fact of its malignancy is the ability to invade and destroy other healthy tissues in its environment (a process called infiltration), and to send cells to distant areas of the body, where they can "nest" or grow causing new tumors, called metastasis.
It originates as a cause of the multiplication and uncontrolled growth of cells. The growth and reproduction of cells is a process that is naturally precisely and carefully regulated.
Cancer can cause any type of sign or symptom, depending on the part of the body where it is located, the size of the tumor and the organs or tissues it affects. Also, when Cancer spreads, signs or symptoms can appear in different parts of the body, even far from where it originated.
There are practically as many types of cancer as there are regions or organs that it can affect.
Age or aging is considered the main risk factor, since two thirds of all cancer cases occur in old age. For example, it was determined in Spain that a very high proportion of tumors were registered in people older than 65 years. The second risk factor is smoking or smoking, and the following are: diet, physical inactivity, exposure to sunlight and ultraviolet rays, as well as lifestyles recognized as unhealthy. Be that as it may, it is not possible to think of cancer as a single cause disease, but rather as the end result of an interaction of various factors including the environment, eating habits, genetic inheritance, etc.
Cancer treatment can be said to be based on three fundamentals: surgery, chemotherapy, and radiation therapy. There is a fourth pillar called biological therapy that would include hormonal therapy, immunotherapy, and new non-cytotoxic therapeutic targets. Cancer treatment is multidisciplinary, and includes cooperation between the different professionals involved (surgeons, medical oncologists, and radiation oncologists), which is of the utmost importance for cancer planning; without forgetting the informed consent of the patient. At all times, emotional support is essential and the search for possible emotional and bodily triggers.
