Chemotherapy for cancer

Cancer Treatment: Chemotherapy (Health And Medical Video April 2018).

A person who first faces a disease in his or her family and is studying treatment methods, it is sometimes extremely difficult to understand what chemotherapy is, how it treats cancer, which are the main types of chemotherapy for cancer. It is important to know that different types of cancer are different drugs, and they are appointed from special schemes.

What is called chemotherapy?

The appointment of chemotherapy always causes a range of feelings in the patients, from fear to hope, but if patients are unaware of the fact that this is a form of treatment, they may, after listening to the wrong statements or the advice of the "experienced", hesitantly abandon such treatment, considering it too dangerous Or useless.

To have objective information, you need to know exactly what chemotherapy is for cancer and how it is done.

Chemotherapy is called the use of herbal, synthetic or even hormonal origin, which affects the growth and development of tumor cells or damage tumor cells.

Yesterday, using chemotherapy, treatment for cancer or significant inhibition of their progression in 40-50% of children is achieved, while 30 years ago healing or continuing the life of one of five patients is a very good result.

Chemotherapy for cancer is one of the components of treatment, it can be applied to surgical or radiotherapy and after it. In some tumors, treatment is possible only by chemotherapy, with others it will significantly extend life, with the third - only improve the state of health.

The purpose of chemotherapy in cancer

Tumor cells acquire special properties and therefore slip out of control of the immune and other surveillance systems of the body. Tumors have uncontrolled growth, squeeze the tissues and poison them.

The purpose of chemotherapy is to inhibit, inhibit or completely stop tumor cell growth. The effect is achieved by direct action of drugs on tumor cells or by breaking the metabolism of tumor tissue itself, as well as limiting the reproduction and growth of tissues.

But, unfortunately, chemotherapy does not work selectively, partly affecting not only the cancerous tissue, but also some healthy tissues. Usually affected by the mucous of the digestive tract, bone marrow tissue, hair growth zones.

As a rule, anti-tumor drugs are used in the most possible dose tolerated, since they have high toxicity and side effects.

In addition, chemotherapy works differently in each organism and gives one pronounced improvement, and the other only an average effect. And this largely depends on the patient's desire to be treated, from his mood and many other factors.

How can chemotherapy be used

The introduction of chemotherapy can be carried out in different ways - systemically, when the drug is administered intramuscularly or intravenously in a dropper, into tablets, subcutaneously or rectally.

With regional chemotherapy, drugs are injected into a tumor-feeding vessel that allows concentrating the substance within tumor education.

There is also a local application of drugs for chemotherapy in the form of ointments or solutions (inside the pleural or abdominal cavity).

In the vast majority of chemotherapy is administered intravenously, rarely tablets and all other methods of administration.

Intravenous administration has more advantages over others:

  • More accurate dosage of the drug;
  • Rapid ingestion of the drug into the bloodstream and its place of action;
  • Slight irritation of undiluted tissues;
  • More rare development of allergic reactions;
  • The ability to quickly cancel the injection in case of unwanted reactions.

But intravenous chemotherapy requires specially trained nursing staff, with inaccurate substance administration, necrosis of the skin and subordinate tissues. In addition, prolonged administration leads to thickening of the veins and the difficulty of administering the drug.

Types of chemotherapy

The number of drugs in the course of chemotherapy can be divided into:

  • Monochiotherapy - it's treatment of the patient with one medicine;
  • Polychemotherapy with a combination of two or more drugs per course.

When polychemotherapy drugs are combined or given sequentially, one by one, sometimes combined with the introduction of hormonal drugs.

Today it is said that combined chemotherapy from several drugs is much more effective, with the fact that the level of side effects in it is not much higher, and sometimes less.

Often chemotherapy is combined with surgery or radiation therapy to heal the effects of treatment. It is necessary to eliminate all cancer cells as much as possible.

Chemistry can be prescribed in front of the rays or surgery (in order to reduce the irradiation or incision zone) or after it, in order to "kill" the remaining tumor cells.

The question of the use of this or that type of chemotherapy should always be discussed in detail with the doctor. Do not hesitate to ask what chemotherapy was prescribed for you, what drugs and which schemes will be used, whether it is possible to do without prophylactic chemotherapy and what if you apply it or refuse it.

Often, chemotherapy can be used as one of the main methods in the common form of cancer, and its main purpose is to destroy the tumor itself, its relapse, or possible metastases.

How to apply chemotherapy correctly

For each type and stage of cancer, select special medications and dosage, based on what kind of tumor, in which the body or parts of the body it is, which is the general condition and operabelnost patient.

For each patient, they develop their cycle of chemotherapy, consisting of rare cases of one drug, usually 2-3 drugs at a time, less than four or more. This is necessary because tumor cells are often not exposed to the same drug, but the combination of remedies they are exposed to, some drugs mutually reinforce their effects.

In addition, the doctor strictly paints the mode of administration, dosage and even the rate of administration of drugs, the interval between the introduction and the severity of toxic manifestations. Medications can be given daily, two or three times a week, every two or three weeks.

The doctor will monitor the tolerability of the drug, dose selection and activity. With low doses, tolerability will be good, but here the tumor will be treated badly, it can continue to grow. At very high doses, there may be too high a risk of fatal complications from the body, therefore produce a fluctuating balance.

Doctors will help to relocate side effects and reactions relatively safely, warn in advance about possible complications, but without them chemotherapy practically does not pass.
