It is commonly prescribed for patients whose cancer is not localized but instead has possibly metastasized, or spread, to various locations in the body. Chemotherapy can be used to reduce the symptoms and pain associated with cancer as well as to slow the growth of cancerous tumors. In some circumstances chemotherapy may even kill spreading cancerous cells. Radiation therapy is a method of treating cancer that utilizes radiation energy. Radiation is most commonly used to treat localized cancers as opposed to cancer that has spread throughout the body.
Invasion assays such as a wound healing assay can be used to measure changes in metastatic potential. E. Relevance: Microtubules have long been targeted for treatment of primary tumors in breast cancer with paclitaxel and similar drugs that stabilize microtubules during mitosis and prevent cell division. However, these microtubule disrupting drugs have not been shown to be effective in the prevention of metastasis. By elucidating the mechanism by which aberrant microtubule nucleation occurs and the proteins involved, new molecular markers can be revealed to create new therapeutics for metastatic breast cancer.
Treatments for Cancer 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.
Another form of personalised medicine is by using magnetic Nano-particles to make the treatment more localised to act as... ... middle of paper ... ...treat this cancer I would use antibody to EGFR attached to nanoparticles and inject it in the cancerous area. The nanoparticle consists of iron oxide and use the iron particle in an alternating magnetic field. This field will generate heat, and cause the cancer cell to burst. This will reduce the size of it and most important will be a localised treatment thus the antibody can recognise the cancer cell and cause fewer side effects in comparison to the conventional way. Unfortunately some side effects can still occur; one of the main factors is that the nanoparticles injected can spread to the normal, healthy cells causing damage and side effects like headaches.
Radiation therapy is an important practice in a lot of hospital and clinics many people are not aware of. It is also known as Radiation Oncology, and it is for the treatment of cancer by using beams of high-energy waves called radiation as the UI Cancer Information Services defined it. Radiation therapy plays important role in helping cure cancer. Radiation therapy is given to cancer patients in order to kill the cancer cells or it may slower the growth of cancer cells (UI Cancer Information Services, 2011). Therapy can be used to reduce pain or pressure by shrinking tumor, in cases where cure is not possible.
In that situation, the doctor removes as much of the tumor as possible during surgery” ("Neuroblastoma - Childhood: Treatment Options"). If the tumor cannot be completely removed by surgery, sometimes doctors will advise chemotherapy or radiation to eliminate the rest. Chemotherapy can also be effective but can have some unwanted side effects. “Chemotherapy is the use of drugs to destroy cancer cells, usually by stopping the cancer cells’ ability to grow and divide . .
By the discovery of new drugs this has allowed cancers that were once fatal to now have a chance of being cured. An example of this is Hodgkin Lymphoma which is now curable. Conclusion In conclusion, there are many different types of cancer each of which have a specific way of being treated. Each method used to treat cancer is effective but some are more effective than others. I personally think that the use of surgery is the most effective way as it can remove a large part of a tumour at the one time.
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 myeloma, sarcoma, also types of lung, breast, intestinal tract, prostate, gastro intestinal, and ovarian cancers. However these chemicals and chemical mixtures can have their side effects. Even though chemotherapy saves lives it, like other medicines, has its side effects. The side effects of chemotherapy, however, and more extreme than the ones you would see on the back of a medicine bottle.
When performing a surgical incision of cancerous tissue, Colonoscopy is the tool that is widely employed for verifying the location of cancerous tumor and removing the surrounding tissues that may be affected (p.71). Prior to the surgery, radiation therapy is often given along with drugs to complete the treatment. In the digestive system, the parts of the large intestine that can be affected by the disease are the colon and/ or rectum. Similar to other cancers, the process in which colon cancer develop can be initiated by various factors, such as steady environmental stresses or inherited abnormalities. Summarized by Adrouny (2002), the first carcinogenesis phase begins with a healthy cell that gets “turned on” into the pathway by accumulated mutation in its genetic material (DNA); this usually occur in the epithelium of mucosa.
Cancer Treatment With Gene Therapy Gene therapy has been progressing over the past half-century and has led to many discoveries pertaining to the treatment of cancer. Normal body cells can either become cancerous by losing or gaining a function. To treat cancer, scientists can either replace damaged genes (such as a damaged tumor suppressing gene) in the malignant cells or stop the cells from overexpressing genes (such as oncogenes, or genes that have been altered and can cause the development of cancer in normal body tissue) (Culver, 97). Gene therapy has many benefits over other cancer treatment methods. “ Gene therapy is the insertion of a functioning gene into the cells of a patient to correct an inborn error of metabolism (i.e.
