Small cell carcinoma Essays

Skin cancers are cancers that arise from the skin. They are due to the development of abnormal cells that have the ability to invade or spread to other parts of the body. There are three main types: basal-cell cancer, squamous-cell cancer and melanoma. The first two together along with a number of less common skin cancers are known as nonmelanoma skin cancer . Basal-cell cancer grows slowly and can damage the tissue around it but is unlikely to spread to distant areas or result in death. Melanomas

INTRODUCTION Figure 1: Molecular Structure of PET PET (or PETE) is also known as polyethylene terephthalate or (C10H8O4)n. Its natural state is a colorless, semi-crystalline resin when combined with other materials like glass fiber or carbon nanotubes, it increases the material’s strength. Polyethylene terephthalate melts at 260°C and Amorphous density (at 25oC) is 1.33 g/cm3. PET can be produced by 2 different reactions as a product of polymerization. The first reaction is between ethylene glycol

Every living animal on earth needs ultraviolet rays to survive. It is essential because it causes the body to produce Vitamin D. Vitamin has the role of strengthening our bones, muscles and our immune system. It will also help skin conditions such as psoriasis and in our life it is useful for disinfection and sterilization because it will kill micro-organisms like bacteria and viruses. (1) But UV rays are also a harmful type of electromagnetic radiation to humans. They can cause sunburn and many

Melanoma starts in a certain type of skin cells that are known as melanocytes that make melanin. Melanin is what gives pigment or color in a human’s skin, eyes, and hair. Melanomas can be inherited or caused by exposure to the ultraviolet rays from the sun. Melanomas can be cancerous, and they are given that name because it relates to that certain type of skin cell that makes melanin (skin pigmentation). Melanoma forms on the epidermis and can be spread

Melanoma is a cancer of the melanocytes, the cell found in the skin's epidermis that produces melanin. Melanoma most commonly occurs on the trunk or lower extremities. While malignant melanoma is less common than non-melanoma skin cancer , it is considered the most deadly form of skin cancer. This is because melanoma accounts for approximately 75% of deaths associated with skin cancer. In 2013, it is estimated that 76,690 people will be diagnosed with melanoma and 9,480 people will die of melanoma

The effects of melanoma can be deadly. Melanoma is a cancer where the cancer cells begins to developed in melanocytes, the pigmented cells that give humans their skin color (Sutton and Frey, par. 1). Melanoma patients were first operated on by a British surgeon in 1787 (par. 20). Patients who have irregular shape moles in their body are at high risk of developing melanoma (Silberman, par.2). The risks of having melanoma include, infection, and cause parts of your body to grow bigger than the other

that exact age. Indoor tanners have also been diagnosed with other varying types of skin issues. The risks of one receiving one of these issue is drastically increased from only one session of tanning. It is possible to get squamous cell carcinoma, basal cell carcinoma, and immune suppression. There is also eye damage that becomes very possible to get such as cataracts and ocular melanoma. It is also possible to get mental problems also like loss of consciousness and tanning addiction. There is

Basal Cell Carcinoma By: Sydni Bejarano and Hannah Primeaux Simple definition Basal cell carcinoma is a disorder of the integumentary system which causes abnormal growths in the Basal layer of the Epidermis. Signs and symptoms The most common signs for basal cell carcinoma include a sore like opening on the skin and marks that may resemble a scar, pink patches, or shiny scabs. Basal cell carcinoma almost never enlarges past its original size, but in some odd cases it can began spreading to other

Automated Melanoma Classification: A Literature Review Introduction A Melanoma is a skin cancer with the highest mortality rate and one of the most common cancers in young adults. Since 1973 the incidences of melanomas has increased by 150% and the mortality rate by 44%. Although melanoma survival rates are poorer than those of other skin cancers, if detected earlier their treatment is more effective (Jain & Jain, 2012). However there is a significant number of cases where melanomas, some of which

I. Introduction A. Attention Getter- The sunburn you get this week could take twenty years to become skin cancer. B. Tie to the audience- Skin cancer is the most common of all cancers. Each year in the US, nearly 5 million people are treated for skin cancer. C. Credentials- I have researched this subject, and I am passionate about it, because I had a cancer scare D. Purpose: Today I want to encourage you to protect yourself from the pain, and even death that can result from skin cancer. E. Thesis:

tell you. I will all so tell you about what it does to our body and some treatments for it. Lung cancer is the growth of cells that start off in the lungs. Those cells that grow there are abnormal cells. This is most common in the cells that line up in the air passages. This cells that grow there will not grow to healthy lung tissue that’s why they are called abnormal cells. When they start to grow they will quickly grow and start to form tumors. So when

cytosponge. The cytosponge is a swallowable device, which collects cells which may contain biomarkers for Barrett's oesophagus, the precursor to esophageal cancer (Lao-Sirieix, P., & Fitzgerald, R. C. , 2010). Around 1% of human cancers start in the esophagus — and only 19% of patients with esophageal cancer survive for five years after diagnosis , making it a serious condition. Adenocarcinoma originates in glandular cells — cells that produce fluids, such as mucus (National Cancer Institute, 2017)

Paranasal cancer Respiratory cancer is a highly serious cancer which may be deadly or leave you severely impaired. The cancer will normally occur anywhere in the lungs, mouth, throat and nose, and if there long enough, it will spread throughout the body. Paranasal cancer is a virus in which forms a tumor in the lining of the nose. It is an infection that mainly affects your sinuses and around the eyes. Cancer.net tells that around two thousand people are being diagnosed with this cancer

Mr.C is a 60-year-old gentleman who was recently diagnosed with oropharyngeal cancer in July 2015 at the Jewish General Hospital. He lives with his two children, 19 and 21 years old, who are both in university studies. His CT scan showed a soft tissue mass on his right tonsil extending posteriorly to the oropharyngeal wall, involving to the right base of the tongue, blocking 75% of his airway. Two months before diagnosis, he was complaining of a sore throat, dysphagia, otalgia and frequent coughing

Skin cancer is the unconstrained growth of irregular skin cells. Skin cancer begins when damaged DNA produces mutations, or genetic defects, that causes the skin cells to spread quickly and form malignant tumors. There are three types of cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Each year, there are over 5.4 million occurrences of nonmelanoma skin cancer that are treated in more than 3.3 million people. The past three decades, there have been more people who’ve been diagnosed

it is also one of the easiest to cure. Our bodies are made up of many different types of cells, and typically cells grow, divide, and die. Although this is the case, sometimes cells mutate and begin dividing rapidly compared to normal cells. In order to form other tumors, cells that are supposed to die clump to others. If the tumors are malignant, they begin to kill the body’s healthy tissues. Cancer cells could spread throughout the body from these tumors in order to form new tumors on the body

caused by large amounts of exposed skin to ultraviolet light. For skin cancer to develop, the skin has to absorb large quantities of exposed UV rays. It damages the cells creating the growth of skin cells to repair and replace the damaged ones. The forming of newer cells continue its growth and does not stop, producing a ball of cells, a tumor. (Skin Cancer Foundation, 2015) “Once that chemical energy has been absorbed by the DNA,

common than other type of skin cancer, but it is most likely to lowly spread around your body. Melanoma cancer is a cancer that starts in a specific skin cell. The main type of skin cells that lead to cancer in your body are Squamous cells, Basal cells and, Melanocytes. Melanoma starts from the Melanocytes. Melanocytes is a skin cell that makes the skin darken when you are in the sun for a long period of time by the help of melanin. Melanocytes produces melanin, melanin leads to a long lasting

I. Type of cancer and Its Effect on Cell Growth: Head and neck cancer includes cancers of the mouth, nose, sinuses, salivary glands, throat, and lymph nodes in the neck. Most begin in the moist tissues that line the mouth, nose and throat. II Possible causes and prevention: Tobacco products play a significant role in about 80 per cent of cases. Researches indicate Eighty-five percent (85%) of head and neck cancers are linked to tobacco use. Another major risk factor is the frequent and heavy

finally the aging of various organs. Of all the tens of thousands of diseases, there is one that people are particularly afraid of, and it is cancer. So why are humans so afraid of cancer? First, because cancer is a deadly disease, once the cancer cells in your body are triggered, it can quickly spread through your body and break through body tissues. Secondly, even after a lot of research, scientists have developed some methods that can treat or alleviate cancer, such as radiation therapy and chemotherapy
