Unlike chemotherapy or targeted therapy, immunotherapy acts slightly differently, since it does not directly affect the tumor, destroying it, but helps the immune system recognize cancer cells for subsequent destruction. Immune therapy blocks the signals that a cancer cell emits against the immune system. Thus, the immune system, without hearing the signals that tricked it into a normal cell, can destroy a cancer cell.
The most commonly used immunotherapy:
Pembrolizumab or Nivolumab are monoclonal antibodies that are directed against the PD1 prot..
Hormone therapy in oncology.
Hormone or anti-hormonal therapy is a pill or injection treatment that inhibits hormone production for men and women. Some hormones tend to stimulate the growth of cancer cells in certain types of cancer. This is due to receptors that are expressed on the plasma membrane of cancer cells. Hormone therapy can be used separately or in conjunction with other types of treatment.
For women, treatment with hormone therapy is prescribed for some types of breast, endometrial, or ovarian cancer.

Chemotherapy is a drug which goal is to stop the proliferation of cancer cells. The drug can be administered intravenously through a catheter in the chest or taken in pills. Once in the blood, it affects the whole body. Regarding cellular exposure, the mechanism of action will differ based on the class of the drug. Most of the therapeutic classes of drugs work through DNA in the nucleus or in the cytoplasm.
Chemotherapy, acting at the DNA level, blocks replication (division) and / or prevents transcription of cells. Thus, most cytotoxic substances..
Targeted therapy works at the cellular level, acting in the environmental area of the cell. It targets a specific receptor or protein located in the plasma membrane. The effect is either on tyrosine protein or on intracellular serine-threonine kinases (a protein that can phosphorylate the protein and regulate intercellular signals, such as proliferation, differentiation, programmed death (apoptosis)).
This type of treatment is classified in accordance with their purpose and mechanism of action. Targeted therapy can be used alone or in conjunction ..
