Breast Cancer
Breast cancer is only one of 200 different types of cancer. It is considered a woman’s disease but both men and women have the disease. Every year, more than 200,000 women are diagnosed with breast cancer. Twelve percent of all women will get the disease and 3.5% of them will die. Breast cancer is the leading cause of death among women who are 40 to 55 years old.
Cancer occurs when cells divide uncontrollably. Cells keep dividing even though new cells are not needed. Change from normal to cancerous cells requires gene alterations.
Altered genes and uncontrolled growth may lead to tumors. These tumors can be benign (NOT cancerous) or malignant (cancerous). Benign tumors won’t spread but it can damage tissues around it. Malignant tumors invade, damage, and destroy nearby tissues and can spread.
Cancer can spread throughout the body when cancer cells break away from malignant tumors and enter the bloodstream. Cancer cells from breast cancer are mostly found in the lymph nodes under the arm when it “spreads.“ When cancer spreads to other parts of the body, it has the same name as the original cancer. So, if you breast cancer ends up in your lungs, it is still called breast cancer!
Breast cancer usually occur in women between the ages of 35 and 65, even though fifty percent of all breast cancer are of women sixty-five and older. The chances of women getting breast cancer has risen within the last couple decades. Between 1973 and 1989, the chance of getting breast cancer rose, on average, at 1.7% per year. In 1960, one out of twenty women had breast cancer. Sadly, it is now one out of nine.
Causes
Even though the exact cause of cancer is unknown, there are many factors that increase your chance of getting the disease. These factors only account for only 30% of all cases of breast cancer. The other 70% are unknown.
Family members with breast cancer - A family history of breast cancer may increase your risk of breast cancer. But just because someone in your family has breast cancer does not mean you will have it too. About 75% of patients with breast cancer do not have a family history of breast cancer Early menstruation, late menopause - Menstruation before the age of 12 and menopause after the age of 50 can increase your risk of cancer.
Age - Women who are older have a higher risk than women who are younger. Also, w...

Surgery
The side effects of surgery depend on the location of the tumor, the type of operation, and other factors. Pain from the operation can be controlled with medicine.
Chemotherapy
Chemotherapy drugs kill rapidly growing cancer cells, but it also kills some “healthy” cells. These healthy cells include blood cells, cells that line the digestive tract, and cells in hair follicles. This results in side effects such as infections, tiredness, temporary hair loss, and mouth sores. And because the drugs lower the patient’s blood count, it may cause anemia. It may also cause the patient to bruise more easily.
Radiation
Radiation may cause a decrease in the number of white blood cells. Other side effects are tiredness, rashes or redness in treated areas, and loss of appetite.
Chances of recovery
Most women treated for early types of cancer live healthy lives after the recovery. But your chance of recover depends on many factors such as the type and stage of your breast cancer, how fast the cancer is spreading, how much the cancer cells depend on female hormones for growth, your age, your menopausal status, and your health.
According to the American Cancer Society, many side effects to radiation therapy occur because normal, healthy cells near the treatment area may become damaged. Temporary side effects may include fatigue, skin changes, hair loss, low blood counts, and eating problems. Longer-term disadvantages to radiation therapy consist of potential damage to the tissue, glands and organs near the vicinity of the tumor, the incapacity to destroy tumor cells that remain undetected on imaging scans, the inability to destroy all cancerous cells in the tumor, infertility, scar tissue growth and more. Unfortunately, when radiation therapy is solely used on particular types of cancers, it may not be entirely successful. This rings true especially for specific cancers that have
There are numerous risk factors for breast cancer. Genetics or family history of breast cancer in a one first-degree relative with breast cancer doubles a woman’s risk. Having two first degree relatives rises a woman’s risk by three times. A person’s personal history who have had one breast with cancer is three to four times as likely of developing a new cancer. White women are slightly more likely to develop breast cancer than are African-American women, but African-American women are more likely to die from this cancer. However in women under 45 years of age, breast cancer is more common in African-American women.
Cancer starts when cells in a part of the body start to grow out of control. Cancer cell growth is different from normal cell growth. Instead of dying, cancer cells continue to grow and form new, abnormal cells. Cancer cells can also invade (grow into) other tissues, something that normal cells cannot do. Growing out of control and invading other tissues are what makes a cell a cancer cell. Cells become cancer cells because of DNA (deoxyribonucleic acid) damage. DNA is in every cell and it directs all the cell’s actions. In a normal cell, when DNA gets damaged the cell either repairs the damage or the cell dies. In cancer cells, the damaged DNA is not repaired, and the cell doesn’t die like it should. Instead, the cell goes on making new cells that the body doesn’t need. These new cells all have the same abnormal DNA as the first cell does.
Tone and diction play a major role in Adams article and the overall efficacy of his writing, his bias against the government and big pharmaceutical companies involving health mandates clearly shows and isn’t hidden, his spiel on the HPV vaccine is filled with satire and personal commentary, “The sick care industry is a for-profit industry, and the more people drug companies can target as being sick today-or even possibly someday being sick at some future date “justifies” treatment right now-the more money they can sock away in the bank.” () Adams utilizes a cartoon to convey to the reader his views of both the parties he claims are in cahoots with one another to endorse the vaccine to gain profit. The title of one of the excerpts in his article is “We must stop the medical tyranny” his placement of the word tyranny is another example of his outlook toward the government, that he acknowledges has plunged itself into a more dictatorship rule that is oppressing the public. Adam’s article seemed more of a political outcry of his own perso...
...effects that can come with chemotherapy such as nausea, vomiting, hair loss, fatigue, mouth sores, and more. Radiation therapy is pretty bad but not as painful with side effects. Side effects for radiation therapy are coughing, fever, fullness of chest, soreness and scaring. Many times surgery is not an option but when is it is one of the best options due to the fact there are less side effects and no strenuous treatment. One of the reasons cancer is such a bad thing is because the treatment is not good but research is taking place and working to get more effective.
Of the few people that know what breast cancer is some of them just believe that it is a lump. They do not know that there is a process to breast cancer they do not know that the tumor comes from somewhere and does not magically appear. Breast cancer can happen a few different ways in the breast, but “the most common type of breast cancer is ductal carcinoma” (cancer.gov). This type of breast cancer begins in the lining of the milk ducts. The ducts are the tubes that carry the milk from the lobules to the nipple. Think of them as little veins running from the nipple to a little pouch. Another place that the cancer could start is...
According to SEER Statistics, 23,380 people are estimated to get a brain or nervous system cancer diagnosis. Out of those people, 14,320 people are estimated to die from their brain or nervous system cancer diagnosis (National Cancer Institute). Cancer is a type of dangerous tumor, or a buildup of extra cells that form a mass of tissue, that can be life threatening (National Cancer Institute). The term for a tumor that is cancerous is a malignat tumor, whereas a benign tumor does not contain cancer cells (National Cancer Institute). According to the National Cancer Institute, the causes of brain cancer are unknown, but risk factors include family history and excessive radiaton exposure. Although they are not always due to a brain tumor, comon symptoms include headaches, nausea, speech, hearing, vision, and mood changes, problems with balance and mamories, seizures, and numbness in arms and legs (National Cancer Institute). MRI and CT scans as well as surgical biposies (or the removal of part of the tumor to be examined) are used to diagnose brain cancer (National Cancer Institute). Different types of treatment options include radiation therapy, surgery to remove the tumor, and chemotherapy. According to Charles Davis, MD, PhD and Nitin Tandon, MD of WebMD.com, chemotherapy is “ the use of powerful drugs to kill tumor cells”. There are a few different types of chemotherapy, but all of which bring out the same kinds of side effects. Although the physical side effects of chemotherapy are commonly known, few people know of the emotional toll chemotherapy can take on a patient and his or her family as they go though this process.
Ever since vaccines came about in the late 18th century, there has been major controversy. The scare of another outbreak common to the flu pandemic of 1918 (that wiped out more than 675,000 Americans) is what pushes the United States today to stay prepared. Since this outburst, America has put out countless vaccines, medications, and intensive care facilities. Whether or not vaccines should be mandatory is a hot topic currently. I believe that the United States should make it mandatory for citizens to get vaccinated.
The process of capture and transportation of dolphins in order to arrive in captivity is brutal and harsh and can lead to many deaths of these creatures. Before the passing of the MMPA, roughly 1,133 dolphins had been captured from the U.S. waters. The most common process of capture of dolphins is called “Seine-Net Capture”. In this process of capture, groups of dolphins are chased by small speed boats and then herded together and encircled by a net. Chasing and net capture of dolphins are extremely stressful and have led to many situations in which accidents have occurred including entanglement in nets and sometimes even death. This whole process is so traumatic that the mortality rates of the species of dolphins has a whole, especially the species of the bottlenose dolphin (Tursiops truncatus) captured from the wild increase six-fold in the first five days o...
Benign tumors look similar to the tissues that they came from and develop slowly. The tumor remains in the same area that the tumor originated in. Malignant tumors are formed from cells that do not resemble the tissue that they came from. They vary in shape and size. This enables pieces of the tumor to break off and spread to other places in the body.
people disagree with the HPV vaccine because of lack of advice, it is important to educate and
As defined by Majure, breast cancer is an “uncontrolled growth of abnormal breast cells” (Majure: 110). It is also one of the cancers that women fear the most. Not only do women get diagnosed with breast cancer, men do too. However, it isn't as bad, or as common, in men as it is in women so doctors don’t recommend screening for men. In the U.S more than one thousand men get affected by breast cancer every year and about two hundred thousand women are affected by breast cancer every year. Women are most likely to get diagnosed with it in their forties and fifties while some may be diagnosed with breast cancer in their twenties, if they started their menstrual cycles at an early age like 14. Typically, men are diagnosed with breast cancer in their sixties or seventies.
Tumors are formed by the alteration of the body’s own cells. This can be caused by environmental factors such as radiation, like UV exposure, chemicals or viruses 1. These can disrupt genes that control growth and cause an increase in cell division and proliferation. Proto-oncogenes are those genes that control normal but essential cell processes that keep cell growth and death in check. Two important categories are apoptosis genes, which regulate cell death, and tumor suppressor genes, which decrease cell propagation 1 . If these genes were mutated to the point where they cannot produce a functioning protein, cell division would continue far past what it was supposed to and unhealthy cells would be allowed to live and continue to multiply. This is what creates a malignant tumor. Certain conditions in the body can also promote the growth of cancer cells. One of these is a deficiency of natural killer (NK) cells, which are able to kill cancer cells by creating a pore in the cell membrane with perforin and releasing granzymes into the cell. Low levels of perforin allow for tumor growth 1. Chronic inflammation can also ...
For most, the primary fears associated with cancer are connected to the effects of treatments. If the patient is diagnosed when the cancer is still in the early stages, more than likely surgery is the appropriate treatment. However if the cancer has developed into an advanced stage, a more drastic treatment is necessary.
Aristotle once wrote, “The voice of the dolphin in the air is like that of the human in that they can pronounce vowels and combinations of vowels, but have difficulties with the constants.” The dolphin is one amazing creature. Dolphins, whales and porpoises are all related. I am going to talk about all aspects off the dolphin from evolution and vocalization to behavior and intelligence.
