Chemotherapy is a combination of words which is chemical therapy. Chemotherapy is a combination of drugs often in liquid forms. Chemotherapy is given when people have a disease that spread. Chemotherapy can work throughout the body so it goes around all of your veins gets all of your tissue so that’s why they put it into veins so that it can get to have every element of your body and which is why it has such a toxic effect because it affects every dividing cells.
One of the most common and well known anti-cancer therapies is chemotherapy.
Chemotherapy is a drug treatment for cancer. Traditional chemotherapy uses cytotoxic drugs to kill cancer cells. Cytotoxic means toxic to cells and cytotoxic drugs act by interfering with cell division. However, this function is not specific to cancer cells only, normal healthy cells may be damaged by this treatment. Healthy cells have a greater capacity for repair and therefore can recover from the damage whereas cancer cells cannot.
Anti-cancer treatment has expanded beyond the use of cytotoxic chemotherapy. So nowadays you likely to receive advance drug treatments such as a hormone, targeted, and immunotherapies. These treatments involve molecules that target specific mechanisms. These cancers cells are dependent upon much more than your normal cells. Cytotoxic chemotherapy might be given at different time points during your anti-cancer treatment journey. For example, it may be given before or after surgery.
Technically chemotherapy is poison, but it’s a poison that ultimately saves a life. The original chemotherapy drug was a derivative of mustard gas. Even though its poison. It’s proved extremely successful in treating cancers throughout the mid-20th century.
Today chemotherapy is used to dramatically improved survival rates for breast cancer. It is the primary form of treatment for cancers of the blood and has great success in the early stages of Hodgkin’s lymphoma. Chemotherapy is used to shrink the tumor before surgery.
The objective of the chemotherapy is to reduce or eliminate cancer cells in the original tumor sites as well as in the other sites of metastasis. Chemotherapy may be either a primary or secondary means of cancer treatment along with surgical excision and radiation therapy.
Chemotherapy drugs may either be given systematically through pills capsules or liquids administered orally intravenously or intramuscularly or locally such as through catheters for a tumor in chest or bladders.
Chemotherapy is work by targeting fast-growing cells which are typical of most cancer cells causing the tumor to shrink because of the decreased cell division and death of the cancer cells.
Chemotherapy is one of the modalities that used in the treatment of cancer patients often in conjunction with surgery and radiation therapy. Cells in the body grow and divide according to the normal cell cycle which controlled by the nucleus. The genetic material or DNA inside the nucleus contains the information necessary to execute this process. If the DNA in the nucleus is get damaged it either repair itself or send the instruction to the cells to die.
In the case of cancer, the portion of the DNA that control cells division is altered resulting in DNA unable to repair itself or instruct the cell to die. This causes the cells to grow and divide uncontrollably creating multiple copies of it called cancer cells. This displays a normal cell to form a tumor. As the tumor increases in size, it also begins to develop its own blood supply as cancer cells do not adhere to each other very well compared to normal cells. They tend to break away and enter the nearest blood vessel thereby spreading to other parts of the body in the process known as metastasis.
Most chemotherapy drugs act systematically by entering the bloodstream to reach the metastatic cancer cells at various organ sites. However, as they are unable to tell the difference between a cancer cell and fast-growing normal cancer cells they often end up attacking normal cells such as those of the bone marrow, digestive system, and hair follicles.
In chemotherapy what trying to do is are to destroy rapidly growing cells that are most cancers. The big side effects the most patients are worried about our hair loss. Often why people lose hair because hair is a rapidly dividing cell, obviously our hair and nails are growing quite a fast basis. We don’t produce the other bits of our bodies in the same way so hair is more likely to be affected by chemotherapy.
Common side effects of chemotherapy include:
- Frequent infection because of a weakened immune system
- Loss of appetite, Nausea, and vomiting.
- Bruising and anemia
According to the national cancer institute, up to 96% of chemotherapy patients experience fatigue. Chemotherapy makes people tired because it changes the endocrine system, metabolism, and serotonin production.
Chemotherapy drugs are often used in combination in order to increase their effectiveness and are generally spread out over a period of week or months to enable the body to recover between treatment cycles as well as to kill as many cancer cells as possible. It’s given on a cycle so that the cycle can keep entering the system and giving your body just enough time to recover. So that it’s not too poisonous but poisonous enough that’s it relentless to interfere with the tumors.
Chemotherapy can be in form of drugs or tablet so it’s very similar to taking antibiotics.
