Drugs And Cancer

Drugs

Chemo has its merits

If there are drugs that have a bad reputation, are those that are used in chemotherapy against cancer. Often patients fear their side effects as the disease that they should fight, if not more. The main drawback of the chemo is not to look anyone in the face: healthy or diseased cells, if they reproduce quickly would I be mown down by his actions.

Yet even the chemo has its merits, and not a few.

Mali curable with chemo-

The study of various tumors has led to the discovery that some of them, known to be aggressive, because of their dizzying growth were also equally sensitive to the action of these medicines. Only one, however, was not enough: the turning point that made some treatable forms of cancer has reached when it became clear that the tumor's ability to continue to transform itself, learning to resist the effect of a single product, one could counter only associating more medicines, which encircle the blocking cancer on several fronts. The same principle that was later used against the AIDS virus.

That's how it changed the fate of those who are ill with testicular cancer.

Forty years ago the diagnosis of this disease was almost a sentence to which a patient survived only ten; the nineties the discovery of more appropriate drugs to treat cancer that has allowed us to turn the tables and nine out of ten patients now recover completely. A reversal of this sort happened in the field of Hodgkin's lymphoma, now have an excellent chance of survival, and childhood leukemia: radiation therapy have also contributed, the first bone marrow transplants and stem cells today, but the result is that a child with leukemia, a time without hope, healing present in 70 percent of cases, and even more when it comes to myeloid.

From genes to treatment

It was also the first in the field of hematology form of cancer that has received a targeted therapy. The observation that chronic myeloid leukemia is characterized by a typical mutation, identified under the microscope by the appearance of the so-called Philadelphia chromosome, has led scientists to create a drug that directly addressed against this genetic abnormality. The results have not been slow to show themselves: compared with traditional chemotherapy the new product, the founder of the so-called targeted therapies, has transformed the expectations of these patients, who responded well to the new treatment in nearly all cases.

It is true that now begin to appear resistance to the drug, but this success has shown that knowledge of the molecular mechanisms underlying cancer is not just a curiosity of scientists, but the best weapon to defeat him. Besides this, other new drugs have already come into use and improved survival in some types of breast cancer and other forms of advanced cancer.

No pain

One of the most important victories, especially cultural, in the fight against cancer, a phase relation of the disease which can no longer speak of healing. Yet today we can say that a terminally ill patient is still a "curable" in the sense that must be cared for all the disorders that they do feel bad and especially the pain. The prospect of suffering the most frightening times of the possibility of death itself: today's palliative care as a whole make it possible to treat it.
