Symptoms And Treatment Of Cancer

In a cell cycle, there are specific checkpoints between each phases caused by the occurrence of cyclin. Cyclin determines how concentration flunctuatues. If the regulation is disrupted by a decreasein cyclin, there would be no mitosis, meaning the cell cycle would continuously go thre G0 phase. However, if there is an increase

The term chemotherapy is defined as: “The treatment of disease by means of chemicals that have a specific toxic effect upon the disease-producing microorganisms that selectively destroy cancerous tissue” (Dictionary of Cultural Literacy). When chemotherapy was first developed at the beginning

Cancer is a defined as a group of cells in the body that begin to divide without stopping and

There are many different type of cancers, there are also many different types of treatments. One of the most known types of treatments would be chemotherapy. Chemotherapy can be used for a wide range of different types of cancers and diseases, and each of the different types of cancers or diseases require a different group, and sometimes order, of chemicals to properly treat the cancer or disease. These chemicals include: Alkylating agents, Antimetabolites, Anthracyclines, Topoisomerase inhibitors, mitotic inhibitors, corticosteroids, and more. Each of these drugs previously listed have its own cancer type(s) or disease(s) that it can assist in treating. Some of these cancers include: Leukemia, Lymphoma, Hodgkin disease, multiple

Without cell division and the cell cycle nearly all life would fail to exist. Cell division allows an organism to not only replace its own cells but to create offspring. The cell cycle consists of two main parts: interphase and mitotic phase. Within these two phases the processes can be broken down into further categories. Interphase can be broken down into three subphases that are the necessary preparations the cell makes in order to be ready to divide during mitosis. For this lab we looked mainly at the mitotic phase because of its fascinating and rapid changes to the cell. The cell types we looked at were prepared slides of whitefish and onion root tip.

Depending on the time of diagnosis and the particular stage at which the cancer is present in the body, treatment options range from a mastectomy, chemotherapy, or surgery (Haas, 2008). A mastectomy is the surgical removal of the breast, it is an approach often taken to halt the spread of cancer cells to other parts of the body. Chemotherapy is an alternative to a treating the cancer. Chemotherapy for breast cancer is a systemic treatment, which affects most of the cells in your body. Most often chemotherapy is classified as the therapeutic use of chemicals to treat or control a particular disease. Potent drugs are used to kill or hinder the uncontrolled growth of cancer cells by interrupting their DNA, protein production, preventing cell division, starving them of their nutrients or blocking hormone receptors (Stephan, 2010).

The cell cycle is a series of stages that occurs when a new cells makes the division from the parent cell to two daughter cells. This is a stage in cellular reproduction. The cell cycle consists of three phases, interphase, mitosis, and cytokinesis. During Interphase, a cell will continue to perform its functions as usual. The time frame for Interphase varies; while an embryonic cell will take just a few hours to complete the cycle, a stem cell from an adult can take 24 hours (Mader, Windelspecht, 2015). After the interphase stage completes itself, a complete nuclear division happens and mitosis occurs. During the stage of mitosis, the daughter cells will receive the same amounts of the contents of the parent cell. Throughout the last stage, in the cytoplasm there is a division known as Cytokinesis (Mader, Windelspecht, 2015). Cytokinesis occurs differently in plant cells than it does in animal cells, as the cell wall around the plant prevents the process from happening the same way. Instead, a new plasma membrane and cell walls are built are built between the daughter cells. However, in animal cells a single cell will become two (Mader, Windelspecht, 2015).

My father was put on chemo after chemo, radiation after radiation, pill after pill they all had different reactions to his body causing different things to happen for different reasons. Some would make him sick, some would make him feel like he was being electrocuted if he got cold, some made him happy, or even weak. No matter what reaction happened to his body, it didn’t get rid of the cancer if anything it made it spread. Soon the cancer was in many different organs of his

Leukemia most common treatments are: Chemotherapy, Radiation therapy, and Bone marrow transplantation, and then there is also Biological therapy. In chemotherapy, patients take one or more anticancer drugs by mouth or, intravenously through IV therapy. In some cases, doctors need to inject the drugs directly into the fluid that surrounds the brain and spinal cord. Chemo can cause side effects, like losing your hair, nausea, fatigue, or easy bruising, depending on the drug. The side effects usually go away progressively between treatments or after treatments stop.

Cure – The desired outcome for all patients, but one that is not always achievable.

    Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.

The first stage is called induction therapy. With induction therapy, the goal is to kill as many leukemic cells as possible in the blood and bone marrow. Restoring normal blood cell production is also a goal with induction therapy. Consolidation therapy is the second phase. Also called post-remission therapy, the goal is to destroy any remaining leukemia in the body. The third phase is maintenance therapy. The goal of maintenance therapy is to prevent leukemia cells from re-growing. Often, this phase is given in low doses over a period of time, most likely over a few years. Sometimes prevention therapy is given during the phases of treatment. Prevention therapy is given to kill any leukemia in the central nervous system. During prevention, chemotherapy is injected directly into the fluids surrounding the spinal cord. As a whole, the phases of treatment are given over a span of 2-3 years, depending on each

Chemotherapy is given in cycles a treatment period followed by a recovery period, then another treatment period and so on. The drug enters the blood stream and destroys leukemia cells throughout the body. However, they cannot reach the brain and spinal cord, because of a protective network of blood vessels that keep foreign substances from entering the central nervous system. In certain cases doctors need to inject the drug directly into the fluid that surrounds the brain and spinal cord. (Health a to z, 20)

1. The Cell cycle consists of various phases, G 1 (growth& preparation of DNA), S (DNA synthesis), G 2 (cell preparation to divide), Mitosis (where chromosomes separate & the cell divides) and G0 (where non-dividing cells exit from the cycle). Cytotoxic therapy is the use of chemotherapy to disturb cellular growth by causing damage to the DNA and impairing cell function (Dougherty & Lister, 2011 p. 870). By affecting the growth and replication of these cells, treatments for patients diagnosed with cancer may be controlled and possibly cured.

The cell cycle is separated into multiple stages such as G0, G1, S, G2, and M phase. During the G0 phase is the stage in which there is no sign of the cell preparing to separate but, rather a stagnant cell. The G1 phase involves the expansion of the cell and gathering all the nutrients and energy to prepare for the upcoming processes of the cell cycle. In the S phase,
