1. Write a brief introduction about the diagnostic imaging modality. Nuclear medicine is a section of medical imaging that uses radioactive medication known as radiotracers or radiopharmaceutical (Understanding nuclear medicine, 2009). Radiotracers are given to the patient through injection, swallowing or inhalation, which makes the body radioactive for a short time. The radiation is detected by a special camera, and then the image is produced.
It is invasive because if it is not treated soon after it happens, it begins to spread to other skin cells and thus, other parts of the body, which can prove to be very deadly. Skin Cancer does not metastasize because it is either in an advanced state or a normal state. The treatment of skin cancer varies greatly on many variables. Treatment of skin cancer can vary on the type of skin cancer, where it appears on the body, whether it is aggressive or not, what stage the cancer is in, and how healthy the patient is. Once those factors have been determined, surgery is performed.
Unit 8 LAB- Photoelectric Effect Created by Young Su Kang Materials: • Google PhET Simulation- photoelectric effect Vocabulary: • Electron volt– a unit of energy that is equal to the energy of an electron that is accelerated by a potential difference of 1 volt • Frequency- the number of times something happens in a given period of time • Intensity- a measure of how much energy passes through a region in a given time • Photoelectric effect- the emission of electrons from the surface of a material when struck by electromagnetic radiation • Photon- the smallest possible amount of light; a quantum of light. • Voltage- a measure of the strength of an electrical field. • Wavelength- the distance between consecutive crests or troughs of a wave • Work function- the minimum energy required to remove an electron from a solid
It is a slow growing cancer that can sometimes spread to the lymph nodes or close to the thyroid gland. Follicular cancer is often diagnosed in middle-aged people and affects around 5 to 10 percent of all thyroid cancer patients. This type of cancer can sometimes disperse throughout the body, mainly the lungs and bones. Both of these forms of cancer are usually curable. Radioactive iodine treatment can be used to destroy any remaining cancer cells after surgery, treat thyroid cancer that has spread throughout the body and heal returning thyroid cancer after it has already been
(8) Skin cancer can be cured depending on the size of the tumor, its type, depth and location. (7) The major treatment for skin cancer is done by removing the abnormal cells, or destroyed, by topical drug therapy. (7) In most cases, the treatment of skin cancer requires only local anesthesia, and can be implemented treat skin cancer on an outpatient basis. (7) Sometimes it may not require, any extra treatment, but if the situation necessitated additional treatment, including potential is freezing, surgical resection, laser treatment for skin cancer, or microscopic surgery. (7) In conclusion, skin cancer is one of the most fatal disease in the world.
Alfred Gilman Sr. Alfred Gilman Sr. created chemotherapy in the early 1940’s. Chemotherapy is a treatment for cancer and is sometimes referred to as chemo. “The goal of chemo is to stop or slow the growth of cancer cells.” Chemotherapy consists of drugs and medicines to treat cancer. “Cancer occurs when certain cells in the body keep dividing and forming more cells without the ability to stop this process.” In the early development of chemotherapy, it was shown that chemotherapy killed lymphatic tissue. As a final point, chemotherapy is an operation used to help cure cancer.
The regimen used depends on the type of NHL, the stage, and whether the disease is aggressive or indolent.4 Chemotherapy is the use of cytotoxic (cell damaging) medicines to target and kill tumors. The drugs work by interrupting the DNA of fast-growing cells, preventing them from growing or reproducing. Chemotherapy can lead to a variety of side effects.4 Radiation therapy uses high doses of X-rays, gamma rays, or other types of ionizing (damaging) radiation to kill cancer cells. It may be applied to the whole body or to a specific
The Anti-Cancer Chemotherapy Drug Gemzar / Gemcitabine Gemzar or Gemcitabine (the generic name) is a anti-cancer chemotherapy drug, used in cancer patients. Gemzar is one of many drugs used in a group of drugs called antimetabolites. The antimetabolites are cells that are similar to the normal cells, they difference is these other cells have different shapes. The structure of theses cells are slightly different. With the antimetabolites this stops the cells from working correctly.
Do you know the organ that has the most common type of cancer? It’s actually the Kidney! About 9/10 cancerous Kidneys are diagnosed with Renal Cell Cancer (RCC). Surgery is the main treatment for most Kidney cancers but it has evolved over time. The reason I selected this topic is because my grandpa had cancer in one of his Kidneys and unfortunately to cure the cancer he had to remove the kidney.
This can be very life threatening and may seriously damage the heart muscle. There are different types of biomedical tests to find out the diagnosis of myocardial infarction. One of which is blood tests to check for heart muscle cell damage, this is usually done using a high sensitivity troponin which is a cardiac and skeletal muscle protein that is used in the laboratory diagnosis of heart attack. They are classed as cardiac markers; troponin I and Troponin T, however they are both sensitive and specific indicators of damage to the heart muscle known as myocardium, they may be measured in the blood to differentiate between unstable angina and heart attack in people with chest pain or acute coronary syndrome. An example a person who may have experienced a myocardial infarction freshly would have an area of damaged heart muscle and raised cardiac troponin levels in the blood.
Lastly, vitamin D deficiency has been linked to the recurrence of breast cancer in other parts of a woman 's body. Advancements in prostate cancer include new research in gene changes that will help understand how the cancer develops. Some hereditary genes that have specific components of the DNA have been found to actually increase the risk of cancer in men. Many scientists have discovered that substances in some foods aid in lowering the risk of contracting the cancer. Lastly, a new treatment made is high intensity focused ultrasound or HIFU, which is used to kill cancer cells in early stages by using high focus ultrasonic
Claire will need specialist doctors and nurses to help her operation when the tumour reaches the lower third of the vagina. There are two parts of this particular stage, 3A and 3B, when the cancer reaches 3A it has reached the lower third of the vagina and when the cancer has reached 3B, the tumour has grown through to the pelvic wall or is blocking one or both off
