Chemotherapy is one of the therapies that have the largest dropout rate for the patients. Most patients are afraid of the chemotherapy and often because they fear that their patients chose to discontinue treatment. Which is unfortunate is the fear of not arise because of the side effects of chemotherapy, but because the wrong information about chemotherapy.
The following is an example of incorrect myths about chemotherapy:
First, chemotherapy has many side effects that are harmful to the body. It may be true
chemotherapy has some side effects. But remember, all medical action is to consider the "Risk" and "Benefit". So the side effects of chemotherapy obtained is much smaller than the benefits to be gained. When compared with untreated cancer let the future it will be far more detrimental than the required therapy.

Tumor
Tumor is commonly used as a synonym for a neoplasm (a solid or fluid-filled (cystic) lesion that may or may not be formed by an abnormal growth of neoplastic cells) that appears enlarged in size. Tumor is not synonymous with cancer. While cancer is by definition malignant, a tumor can be benign, pre-malignant, or malignant, or can represent a lesion without any cancerous potential whatsoever.
A neoplasm can be caused an abnormal proliferation of tissues, which can be caused by genetic mutations. Not all types of neoplasms cause a tumorous overgrowth of tissue, however (such as leukemia or carcinoma in situ).

Sarcoma
Sarcoma is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancerous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma. Sarcomas are quite rare - common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma.
Sarcomas are given a number of different names based on the type of tissue from which they arise. For example, osteosarcoma arises from bone, chondrosarcoma arises from cartilage, liposarcoma arises from fat, and leiomyosarcoma arises from smooth muscle.

Lung Cancer
Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung in a process called metastasis into nearby tissue and, eventually, into other parts of the body. Most cancers that start in lung, known as primary lung cancers, are carcinomas that derive from epithelial cells. The most common symptoms are shortness of breath, coughing (including coughing up blood), and weight loss.
The main types of lung cancer are small-cell lung cancer (SCLC), also called oat cell cancer, and non-small-cell lung cancer (NSCLC). The most common cause of lung cancer is long-term exposure to tobacco smoke. Nonsmokers account for 15% of lung cancer cases, and these cases are often attributed to a combination of genetic factors, radon gas, asbestos, and air pollution including secondhand smoke.

Liver Cancer
Liver cancer or hepatic cancer is a cancer that originates in the liver. Liver cancers are malignant tumors that grow on the surface or inside the liver. Liver tumors are discovered on medical imaging equipment or present themselves symptomatically as an abdominal mass, abdominal pain, jaundice, nausea or liver dysfunction. Liver cancers should not be confused with liver metastases, which are cancers that originate from organs elsewhere in the body and migrate to the liver.
There are many forms of liver cancer, although many cancers found in the liver are metastasis from other tumors, frequently of the GI tract (like colon cancer, carcinoid tumors mainly of the appendix, etc.), but also from breast cancer, ovarian cancer, lung cancer, renal cancer, prostate cancer, etc.

Metastasis Cancer

Metastasis Cancer (abbreviated mets), is the spread of a disease from one organ or part to another non-adjacent organ or part. It was previously thought that only malignant tumor cells and infections have the capacity to metastasize; however, this is being reconsidered due to new research.
Cancer occurs after a single cell in a tissue is progressively genetically damaged to produce a cancer stem cell possessing a malignant phenotype. These cancer stem cells are able to undergo uncontrolled abnormal mitosis, which serves to increase the total number of cancer cells at that location. When the area of cancer cells at the originating site becomes clinically detectable, it is called a primary tumor.
Some cancer cells also acquire the ability to penetrate and infiltrate surrounding normal tissues in the local area, forming a new tumor. The newly formed "daughter" tumor in the adjacent site within the tissue is called a local metastasis.
Hepatitis
Hepatitis (plural hepatitides) is a medical condition defined by the inflammation of the liver and characterized by the presence of inflammatory cells in the tissue of the organ. The condition can be self-limiting (healing on its own) or can progress to fibrosis (scarring) and cirrhosis.
Hepatitis may occur with limited or no symptoms, but often leads to jaundice, anorexia (poor appetite) and malaise. Hepatitis is acute when it lasts less than six months and chronic when it persists longer. A group of viruses known as the hepatitis viruses cause most cases of hepatitis worldwide, but it can also be due to toxins (notably alcohol, certain medications, some industrial organic solvents and plants), other infections and autoimmune diseases.
The liver, like all organs, responds to injury in a limited number of ways and a number of patterns have been identified. Liver biopsies are rarely performed for acute hepatitis and because of this the histology of chronic hepatitis is better known than that of acute hepatitis.

Thalassemia
Thalassemia is an inherited autosomal recessive blood disease that originated in the Mediterranean region. In thalassemia the genetic defect, which could be either mutation or deletion, results in reduced rate of synthesis or no synthesis of one of the globin chains that make up hemoglobin. This can cause the formation of abnormal hemoglobin molecules, thus causing anemia, the characteristic presenting symptom of the thalassemias.
Thalassemia is a quantitative problem of too few globins synthesized, whereas sickle-cell disease (a hemoglobinopathy) is a qualitative problem of synthesis of an incorrectly functioning globin. Thalassemias usually result in underproduction of normal globin proteins, often through mutations in regulatory genes. Hemoglobinopathies imply structural abnormalities in the globin proteins themselves.

Cardiac arrest
Cardiac arrest is the cessation of normal circulation of the blood due to failure of the heart to contract effectively. Medical personnel can refer to an unexpected cardiac arrest as a sudden cardiac arrest or SCA.
A cardiac arrest is different from (but may be caused by) a heart attack, where blood flow to the muscle of the heart is impaired.

Cancer Cell
Cancer cells are cells that grow and divide at an unregulated, quickened pace. Although cancer cells can be quite common in a person they are only malignant when the other cells (particularly natural killer cells) fail to recognize and/or destroy them.
In the past a common belief was that cancer cells failed to be recognized and destroyed because of a weakness in the immune system. However, more recent research has shown that the failure to recognize cancer cells is caused by the lack of particular co-stimulated molecules that aid in the way antigens react with lymphocytes.

Polio
POLIO
Polio (also called poliomyelitis) is a contagious, historically devastating disease that was virtually eliminated from the Western hemisphere in the second half of the 20th century. Although polio has plagued humans since ancient times, its most extensive outbreak occurred in the first half of the 1900s before the vaccination created widely available in 1955.Polio is a highly infectious disease caused by a virus. It invades the nervous system, and can cause total paralysis in a matter of hours. The virus enters the body through the mouth and multiplies in the intestine.
Antibody
An antibody, also known as an immunoglobulin, is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, termed an antigen.
Each tip of the "Y" of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly.

Parasitism
Parasitism is a type of symbiotic relationship between organisms of different species where one organism, the parasite, benefits at the expense of the other, the host. Traditionally parasite referred to organisms with life stages that went beyond one host, which are now called macro parasites.
Parasites can now also refer to micro parasites, which are typically smaller, such as viruses and bacteria and can be directly transmitted between hosts of one species.
Not like predators, parasites are usually much smaller than their host, even though both are special cases of consumer-resource interactions. Parasites show a high degree of specialization for their mode of life, and reproduce at a faster rate than their hosts.

Infection
An infection is the colonization of a host organism by parasite species. Infecting parasites seek to use the host's resources to reproduce, often resulting in disease. Colloquially, infections are usually considered to be caused by microscopic organisms or micro parasites like viruses, prions, bacteria, and viroids, though larger organisms like macro parasites and fungi can also infect.
Hosts normally fight infections themselves via their immune system. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Pharmaceuticals can also help fight infections. The branch of medicine that focuses on infections and pathogens is infectious disease medicine.

Down Syndrome
Down syndrome is a chromosomal condition caused by the presence of all or part of an extra 21st chromosome. It is named after John Langdon Down, the British physician who described the syndrome in 1866. The condition was clinically described earlier in the 19th century by Jean Etienne Dominique Esquirol in 1838 and Edouard Seguin in 1844.
The effects and extent of the extra copy vary greatly among people, depending on genetic history, and pure chance. The incidence of Down syndrome is estimated at 1 per 733 births, although it is statistically more common with older parents (both mothers and fathers) due to increased mutagenic exposures upon some older parents reproductive cells. Down syndrome occurs in all human populations, and analogous effects have been found in other species such as chimpanzees and mice.
Apoptosis
Apoptosis is a biological mechanism which is one type of programmed cell death. Apoptosis is used by multicellular organisms to remove cells that are not needed by the body.
Apoptosis is different from necrosis. Apoptosis is generally lasts a lifetime and be beneficial for the body, while necrosis is cell death caused by cellular damage acutely.
A concrete example of the advantages is the separation finger apoptosis in embryos. Apoptosis experienced by the cells located between each finger causes the finger to be separated from each other. When cells lose the ability to perform the apoptotic cells can divide indefinitely and eventually become a cancer.
Leukemia
Leukemia known as blood cancer is a disease in the classification of cancer (neoplasm) in the blood or bone marrow characterized by the abnormal multiplication or malignant transformation of blood-forming cells in bone marrow and lymphoid tissue, commonly occurs in leukocytes (white blood cells).
Normal cells in the bone marrow are replaced by abnormal cells. These abnormal cells out of the marrow and can be found in the peripheral blood. Leukemic cells affecting hematopoietic or blood cell formation process and the immunity of the patient.
Hemophilia
Hemophilia is a genetic blood disorder caused by a deficiency of blood clotting factors. Hemophilia A occurs if there are abnormalities in the gene that causes a lack of clotting factor VIII (FVIII). Hemophilia B lack of clotting factor IX (FIX). Hemophilia A and B cannot be distinguished because it has a similar clinical appearance and a similar pattern of gene inheritance.
Hemophilia is a genetic disease of the oldest ever recorded. Inherited bleeding disorder that occurs in a male was recorded in file Talmud in the Second Century. Modern history of hemophilia began in 1803 by John Otto was there a child who suffered from hemophilia.
