The skin‚ or epithelial tissue‚ primarily consists of 3 distinct layers‚ the epidermis‚ dermis‚ and hypodermis‚ respectively. The epidermis‚ or outermost layer of the skin‚ is comprised of 5 layers: stratum corneum‚ stratum lucidum‚ stratum granulosum‚ stratum spinosum‚ and stratum basale. The skin is comprised mainly of squamous cells‚ basal cells‚ and melanocytes. Skin cancer is the most known form of cancer found in the United States‚ with over 54 million individual nonmelanoma related skin

any part of the body. One defining feature of cancer is the rapid creation of abnormal cells that grow beyond their usual boundaries‚ and which can then invade adjoining parts of the body and spread to other organs. This process is referred to as metastasis. Metastases are the major cause of death from cancer. Key facts: Cancers figure among the leading causes of death worldwide‚ accounting for 8.2 million deaths in 2012 . Lung‚ liver‚ stomach‚ colorectal and breast cancers cause the most cancer

the liver include: • Breast cancer • Colorectal cancer • Esophageal cancer • Lung cancer • Melanoma • Pancreatic cancer • Stomach cancer The risk of cancer spreading to the liver depends on the site of the original cancer. A liver metastasis may be present when the original (primary) cancer is diagnosed‚ or it may occur months or years after the primary tumor is removed. Symptoms In some cases‚ there are no symptoms. When symptoms occur‚ they may include: • Anorexia • Confusion

Question 1: (see full question) Which of the following observations should the nurse make first when the client who has had a modified radical mastectomy returns from the operating room to the recovery room? You selected: Ensuring that the client’s airway is free of obstruction. Correct Explanation: The highest priority when a nurse receives a client from the operating room is to assess airway patency. If the airway is not clear‚ immediate steps should be taken so that the cli... (more)

characteristically slow growing with clinical behavior reflective of a low-grade tumor‚ acinic cell carcinoma can recur in 25—50% of patients if not treated adequately [Spafford et al‚ 1991]. A subset of acinic cell carcinomas are clinically more aggressive with metastasis to regional lymph nodes and distant sites‚ particularly the lung‚ at presentation. Histologic grading of acinic cell carcinomas is controversial and‚ unlike clinical stage‚ histomorphology has not proven to be reliable in predicting behavior. The

Cervical cancer begins with the abnormal growth of cells lining the cervix. The cervix is located in the lower‚ more superficial‚ region of the uterus. The two types of cells that make up the cervix include nonkeratinizing‚ stratified squamous cells on the exocervix and mucus-secreting‚ columnar cells on the endocervix. The transformation zone contains the squamocolumnar junction where the columnar and the squamous cells meet. This area is the embryonic cell population that is involved in cervical

Overview | | About Ovarian Cancer Cells in the body normally reproduce themselves in an orderly manner. But in cancer the cells start dividing uncontrollably‚ and do not die the way normal cells do. As the cells produce more cells‚ a mass or tumor may appear. The tumor can invade surrounding tissue and keep the healthy tissue from doing its normal job. There are two kinds of tumors: * Benign tumors are not life threatening. They do not invade other tissues and when they are removed they

cancer cells along until they get stuck somewhere. Usually they get stuck in a very small blood vessel called a capillary. Out of many thousands of cancer cells that reach the blood circulation only a few will survive to form a secondary cancer or metastasis. Some cancer cells are probably killed off by the white blood cells in our immune system. Others cancer cells may die because they are battered around by the fast flowing blood. Cancer cells in the circulation may try to stick to platelets to form

cells then form a tissue and turn into a tumor. This tumor typically grows into nearby tissues or breaks away and enters the bloodstream or lymphatic system which can affect other organs. The spreading of breast cancer is generally referred to as metastasis (Kopans‚ 1989). The most common and effective method for detecting breast tumors in their early stages is by performing mammogram screening. Mammography is currently the most effective modality used to detect tumors in the breast tissue (Sickles

Cancer cells also break away from the original tumour and enter the bloodstream or lymphatic system. This spread of the cancer is called metastasis. Breast cancer may appear as a lump but there are many different types of breast lumps. Most lumps are harmless‚ or benign. Benign lumps are abnormal‚ but not life-threatening. Who is at most risk? Men? Female? Or both of them will get
