Skin Cancer
Describe the pathophysiology of the general process of abnormal cellular growth as it relates to all types of cancer.

Normal cells become cancer cells because of DNA damage. In cancer cells, damaged cells are not repaired and they do not die; instead, the cells reproduce damaged cells. These cells grow out of control and invade other tissues (American Cancer Society, 2013).

Compare and contrast the pathophysiology of basal cell carcinoma, squamous cell carcinoma, and malignant melanoma.

Basal cell carcinomas develop in the basal cell layer of the skin, usually due to sun light exposure causing DNA damage in the form of thymine dimers. Squamous cell carcinoma develops from the epidermal ketarinocytes, generally from sun exposure although other carcinogens can cause this cancer on skin that does not get sun exposure. Malignant melanoma arises from melanocytes and can occur spontaneously or from preexisting lesions and are linked to sun exposure.

Skin cancer [...] disease, its diagnosis, how it is treated, the different forms, and the causes of the disease. Skin cancer is a growing problem in society because so many people misunderstand it. It is also the most common form of cancer, so more needs to be done to educate people about the dangers of skin cancer to help control the disease and its spread.
In 1993, it was estimated that 700,000 new cases of skin cancer would be diagnosed (Sherry 81), and every year the numbers get larger, according to the Skin Cancer Foundation, a worldwide group working to treat and prevent the disease. In addition, "About 41,600 Americans were diagnosed with malignant melanoma in 1998, and 7,300 died from the disease" (Goff 28). These numbers have increased dramatically since 1930, and it seems as more Americans have fun in the sun, they will pay later when skin cancer…...

Merkel Cell Carcinoma is a relatively rare, but highly aggressive type of skin cancer. Discovered in 2008, it is typically caused by a virus known as Merkel Cell Polyomavirus (MCPyV). At times, the disease may be known as APUDoma, a primary neuroendocrine carcinoma of the skin, or primary small cell carcinoma. However, from a pathological perspective, 80% of Merkel Cell Carcinoma (MCC) are called by the polyomavirus. Interestingly, the virus has a clonal integration into the cancerous cells, and a particular mutation only when in the cancerous cell, not a healthy skin cell. No other cancers have been confirmed to be caused by this virus, and because of the viral origin of the cancer, immunotherapies are one of the most promising avenues for treating virus-positive MCC. However, at present, little is known regarding the virus-host interactions from a biochemical perspective. Research does show, though, that a new function of the…...

There is a previously undiscovered function of MCPyV and antigens as a cellular inhibitor that may, in certain cases, explain the relationship between the virus and the manner in which MCC so aggressively and quickly attacks other cellular structures of the body. What appears to be happening is that the combination of the MCPyV and small and large antigens work in tandem to destabilize the body's natural immune response, which particularly when the individual's immune system is already compromised, increases the seriousness and likely persistent infection of not only the host cell but the surrounding cells. It also appears that certain aspects of ultraviolet light may act in conjunction with MCPyV to enhance the virus' natural tendency towards rapid and efficacious infection. This may, in part, be due to particular mutations caused by heavy exposure to certain light frequencies, which then tend to damage the interactions between cellular proteins and cellular phosphatase subunits that, in healthy cells, tend to act with proteins as a protectant and mediation unit to repair damaged structures.

The picture to the left depicts the various elements that are responsible for thermoregulation in human skin. The illustrations shows the various layers of skin along with the veins, arteries and capillaries of the circulatory system that assist in insuring that the thermoregulatory system works properly. The sweat glands are responsible for selectively removing materials from the blood the sweat glands then concentrates or alters these toxins, and secretes them for elimination from the body. The perspiration or sweat is then removed through the sweat pore. This has a twofold purpose: to remove toxins and thermoregulation (in this case cooling the body).

Thermoregulation involving perspiration is brought about by both internal and environmental heat and exercise. As it relates to the latter, there have been many studies related to exercise and thermoregulation. According to Marino (2004)

Cancer and Women’s and Men’s Health Cervical cancer is a kind of cancer that takes place in the cells of the cervix, which is basically situated in the lower part of the uterus that links to the vagina. It is imperative to note that different strains or forms of the human papillomavirus (HPV), a sexually transmitted infection, have a role to play in giving rise to a great deal of cervical cancer.
Available Preventative Services
The United States Preventive Services Task Force (USPSTF) gives the recommendation of screening for cervical cancer in women between the ages of 21 years to 65 years with pap smear for every three-year period. It is also recommended for women between the ages of 30 and 65 years who wish to prolong the screening period, and therefore screening with a mixture of cytology and human papillomavirus testing for every five-year period. In the same manner, the task force…...

Screening for breast cancer before there are symptoms is very important. Screening helps doctors find and treat cancer in its early stages. Treatment is more likely to be successful when the cancer is detected early. A doctor may suggest any of the following screening tests for breast cancer: screening mammogram, clinical breast exam, beast self-exam (Stoppler, 2009).
Mammograms can often show a breast lump before it can even be felt. A mammogram is a picture of the breast that is made with an x-ray. It can also show a cluster of tiny deposits of calcium. These deposits are known as micro calcifications. Lumps can be from cancer, precancerous cells, or a host of other conditions. Further tests may be needed to find out if abnormal cells are present. Women in their 40s and older should have mammograms every 1 to 2 years (Stoppler, 2009).

Dietary Fibers on the Risk of Developing Cancer
Cancer is a genetic and complex disease caused mainly due to environmental elements. Carcinogen is a cancer agent that and can be present in water, food, air and in sunlight and chemicals as well. Almost ninety percent of the cancer occurs in epithelia because the epithelia cells cover the human's skin, lines the alimentary and respiratory tracts, and also metabolize ingested carcinogens. Currently, the causes of diseases are changing and infection can cause problems like cancer and cardiovascular diseases. There were more than ten million cancer cases in 1996 globally while six million people died from cancer. Unhealthy lifestyle like smoking cigarettes and adopting modern diet that includes fiber content and high fat is causing increased incidences of cancer in humans (Alison).

It is important to note, from the onset, that breast cancer has been identified as one of the leading causes of death amongst women across the world. According to the Centers for Disease Control and Prevention – CDC (2018), without taking into consideration some skin cancer types, breast cancer is not only “the most common cancer in women” in the United States, but also “the second most common cause of death from cancer among white, black, Asian/Pacific Islander, and the American Indian/Alaska Native women.” The first position, as far as mortality rates amongst women with cancer is concerned, is occupied by lung cancer.
The most prominent symptom of breast cancer is a lump inside the breast. Other symptoms, according to the National Cancer Institute (2018), could be inclusive of an inverted nipple, sore nipple, and breast pain.…...

Care of Cancer:
In the past few years, cancer has developed to become one of the major leading causes of deaths across the globe. The disease can be described as the uncontrolled growth or development of abnormal cells in the body even as cancerous cells are also known as malignant cells. Since cells are the building blocks of humans and other living things, cancer develops out of the normal cells within the body. Generally, the normal cells multiply when needed by the body and die when the body does not need them. When the growth of the cells in the body is out of control and cells divide too quickly, cancer appears to occur. Nonetheless, cancer also appears to happen when cells in the body forget how to die.

Causes of Cancer:

There are various kinds of cancer because the disease can develop in nearly every tissue or organ like skin, bones,…...

Cancer diagnosis

In many cases the sooner cancer is diagnosed and treatment begins the better the chances of a person recovering fully. If one develops cancer they can improve the chance of early detection if they have regular medical checkups and do some self-exams. Doctors often find early cancer during a physical exam or when carrying out routine tests even when there were no symptoms presented.

There are several methods that are used to diagnose cancer .with technological advancement these methods are now better as they help in a better understanding of cancer .there are now many diagnostic tools that can be used in cancer detection.

Treating and Coping With Pancreatic Cancer
Although significant progress has been made in diagnosis and treating many types of cancers, one type of cancer that remains highly intractable to treatment is pancreatic cancer. In fact, pancreatic cancer is difficult to detect because symptoms may not occur until the condition is well advanced, and even when it is diagnosed early, patient prognoses are poor. Although pancreatic cancer represents just around 3% of all types of cancers in the United States, the condition is responsible for approximately 7% of all cancer deaths (Key statistics, 2015). This paper provides a description of the diagnosis and staging of pancreatic cancer followed by a discussion concerning the complications and side effects that are associated with the disease. Finally, a description of the methods that are used to lessen the physical and psychological effects of treatment for pancreatic cancer is followed by a summary of the research…...
