Radiation therapy is the ionization of atoms in tissues resulting in formation of highly reactive radicals in a well-defined, restricted volume (1). In other words, ionizing radiations are used to eradicate tumors and at the same time preserve structure and function of normal tissue. A limitation is prevented from being a problem. If bone marrow or neuronal cells are destroyed or injured, they do not regenerate. However, with radiation therapy, these cells are often saved from injury or destruction, unless the tumor is infecting bone marrow or neuronal cells. Today, radiation therapy is the most popular type of cancer therapy in use. It is used to treat one-half to two-thirds of all cancers, which translates to more than ten percent of the population
Throat cancer Mt Pleasant TX is one of a number of cancers that are highly preventable and highly curable. According to The American Institute for Cancer Research, 63% of mouth pharyngeal and laryngeal cancers can be prevented by making simple lifestyle changes. But statistics that tout the preventability of a certain type of cancer are not much comfort after a diagnosis has been made. If you’ve been diagnosed with a type of throat cancer or you fear you’re at risk, here are some things you should know:
Radiation works by damaging the genes in cancer cells. DNA genes control how cancer cells grow and divide. When radiation damages the genes of the cells, they can not grow and divide any more. Over time, the cancer cells die. This means radiation therapy can be used to kill the cancer cells and shrink
2.1.1. Epidemiology Head and neck squamous cell carcinomas (HNSCCs) is the sixth most common cancer with an annual incidence of ~400.000 cases (Duray et al., 2012)6 and represents about 3.5% of all malignant tumors Siegel et al., 2012). Head and neck SCC is quite heterogeneous and most of the tumors arise in the oral cavity, oropharynx, hypopharynx and larynx. Nearly 90% of these cancers are OSCC, which is associated with a poor prognosis, with a 5-year survival rate less than 50% (Osei-Sarfo et al.,
NIDCR data shows that the 5 year survival rate for oral cancer that has remained localized is 83 percent in comparison to 32 percent for those whose cancer has spread to other areas of the body. This is why recognizing the signs and symptoms of oral cancer, having regular oral cancer screenings and receiving early treatment is so critical to a positive outcome.
Radiation therapy can be used anywhere in the body to treat any kind of cancer. Depending on what type of radiation therapy, it can have some side effects. The most common ones include fatigue, hair loss near the treated area, and skin darkening in the area exposed to a beam of radiation. ("Radiation Therapy for Cancer,” 1) There are also safety concerns that patients have when they are treated with radiation therapy. Many people that receive radiation therapy treatment, worry about exposing family and love ones to radiation, as well as the side effects. Radiation effects on the normal tissues are divided into acute and chronic effects (Schreiber). Acute effects occur during the course of therapy and during the post therapy period (approximately 2-3 weeks after the completion of a course of irradiation) (Schreiber).
Radiotherapy is the general term to indicate the treatment with the use of x-rays. The tumor area that requires therapy is treated with high-energy beams painless. The radiotherapy kills cancer cells and can be used either alone or in combination with surgery and / or chemotherapy.
A common tool used to detect oral cancer is an endoscopy, is a lighted scope that can also be used to see if the cancer had spread through the throat. Imaging tests, like x-rays, are other great ways to be able to diagnose patients with oral cancer (Christian). When patients are now diagnosed with oral cancer doctors make sure at what stage their cancer is in. Oral cancer has about four stages depending of the tumor's growth and where it has spread through the body will determine on what stage it is found. In stage (I), the tumor is under 1 inch in diameter and has not reached nearby lymph nodes. If for any case the tumor has reached any lymph nodes, found in the head or in the neck, then it's more likely that the tumor will have access to spread through other organs like affecting your blood stream or bones. Stage (II), the tumor is over 1 inch and has not reached any nearby lymph nodes. In stage (III), The tumor can be 2 inches in diameter, and is possible to touch a nearby lymph node. In stage (IV), the cancer has aggressively flourished to other lymph nodes on the same and opposite side of the neck and has spread to other parts of the body ( Christian ). The earlier oral cancer is discovered the better results the patient will have. Mainly 90% of people with stage (I) or (II) will be able to survive at least five years after being treated, others diagnosed with later stages of oral cancer have minimum chances to stay cancer-free for the next five
Cancer of the head and neck are diagnosed each year with a high incidence of laryngeal cancer. Maddox and Davies (2012) reported that, “The estimated number of Laryngectomies performed in 1997 was 5,038, this number dropped steadily to a low of 2,966 in 2006 and then rose slightly in 2008 to 3,414”.Men and women both seek surgery to alleviate the problem. Total laryngectomy is undertaken in as many as 50% of patients with a relative survival rate of 52% with no significant
There are numerous approaches that are taken when treating cancer and although they all have the same goal of accomplishing the treatments differ from the way they are administered to the way they work on one’s body. Differing to chemotherapy which happens to be one of the most common methods of treatment used radiation therapy just so happens to be used to target one specific area of the body where the cancerous cells are present and causes effect to that specific area as opposed to the whole body being exposed to cancer fighting drugs. This usually is the result of beams of intense energy where the power is normally coming from X-rays but can often times be delivered from other forms of energy. While it is not guaranteed that healthy cells
Once a person has been diagnosed with cancer, the person may be advised to generally undergo the following treatment options: radiation, chemotherapy, surgery, or a combination of the three therapies.2 The current issues that are associated with these treatments include low selectivity toward malignant cells, causing damage to healthy tissue and forcing the
