He Cancer is defined by the Royal Spanish Academy (RAE) like a neoplastic disease with transformation of cells . The term also allows reference to a malignant tumor .
The use of the concept usually refers to the set of diseases which involve an excess of malignant cells (cancer cells), which produces an invasion of the surrounding tissue or the metastasis (the distant spread of these cells) that leads to the development of new tumors. The cells reproduce to the extent that the body requires it and they are replacing (new ones are born and those that no longer serve die); cancer becomes present when cell reproduction takes place out of control, dividing too quickly or because cells that no longer serve seem to have forgotten how to die.
Cancer affects individuals of all ages and may even arise in the fetus. It is a disease that causes about 13% of worldwide deaths and kills millions of people a year.
The cause of cancer is unknown, although there are several risk factors that favor its appearance. Aging, smoking, sun exposure or various chemical agents, sedentary lifestyle and diet they are factors that, in certain cases, can precipitate the development of cancer.
Cancer treatment can be done through a surgery , radiotherapy or chemotherapy sessions , according to the specificities of the disease in question and the response of the organism.
The medical specialty dedicated to the study and treatment of benign and malignant tumors is called oncology . Oncologists can diagnose cancer, indicate appropriate treatment, follow up on said treatment and / or appropriate palliative care.
On the other hand, Cancer is a Zodiac sign to which belong those born between June 22 and July 22.
Cancer and life expectancy
exist various types of cancer, among the most common we can mention breast, lung, skin and tissue cancer and among the most known causes is the exposure to certain chemicals, environmental toxins or aflatoxins excessive alcohol consumption, exaggerated exposure to sunlight, genetic agents, obesity, radiation exposure. In any case, doctors often fail to find the real origin of this medical condition.
Some specialists say that this it is the disease of our era, caused and increased by the rhythm of life to which we are exposed.
While it is true that the life expectancy of human beings has grown considerably in number and about 50 years ago it was 50 or 60 years, now it has reached 70 or 80; Nevertheless On an ethical level the question that arises is at the expense of what? Is it worth keeping a sick person's life from that abysmal terror of death? Some people think that yes and that is why instead of living 5 years enjoying what they have left of existence, they prefer to be sentenced to 10 or 15 years of rays, chemotherapies and operations To live as much as they can.
Possibly there is no single way to understand and treat this disease; however it is interesting to remember that the Western medicine only treats the iceberg of the problem, does not address the root of it, so a person who overcomes a cancer runs the risk of getting it again, because the psychic reasons that led him to get sick they are not analyzed or confronted. In other cultures, the way to treat these diseases is through harmony and integral healing of the organism and, in many cases, amazing results are achieved.
