Cancer is a recognized risk for thromboembolic events (TEE) with rates in this population being up to four higher than the general population [1,2]. Indeed, up to 30% of TEE occur in cancer patients [3-5]. These events, in addition to attendant morbidity and mortality contribute additional economic burden to the health care system with costs of hospital management estimated at about $20,000 per patient [6,7]. TEE are held to be the second leading cause of death in cancer patients [8] and patients with TEE over all have poorer outcomes with a 2 fold increase in death rate within 2 years of diagnosis in patients with breast cancer [9]. The spectrum of TEE described in cancer includes, but is not limited to venous thrombo-embolism (VTE), arterial thrombosis, thrombocytic nonbacterial endocarditis and disseminated intravascular coagulopathy (DIC)[10,11]. VTE; including deep vein thrombosis (DVT) and pulmonary embolisms (PEs) represent the majority of TEE [12] and are thus the most commonly commented on.
In addition to risks factors for TEE described in the general medical population, a number of factors peculiar to the cancer patient have been identified as contributing to the hypercoagulable profile. [13]These have been grouped into cancer related, patient related and treatment related factors [14]. Compared to cancer involving other organs like the brain, lungs and pancreas; breast cancer is considered low risk for VTE [15]. However, given the prevalence of breast cancer in the population, it is not surprising that this cohort of patients contribute significantly to the new cases of VTE in the cancer population particularly in the context of advanced disease and chemotherapy [16]. We intend to highlight the role of chemotherapy ...

Conclusion and Future Perspectives
Important advances continue to be made in uncovering the pathobiology of and risk factors for thromboembolic events in cancer. These advances are providing evidence that support individualizing the management of venous thromboembolism in breast cancer patient on chemotherapy based on risk factors. Even though breast cancer is considered low risk for VTE, incorporating risk assessment models in the outpatient setting may help identify a cohort of patients who would benefit from prophylactic therapy and those who are at increase increased for VTE recurrence. The role of TSOACs in the management of VTE in cancer needs to be further defined. Given the central role of Tissue Factor in the pathogenesis of VTE in cancer, targeting this protein seems logical in the hunt for the perfect anticoagulant.
Many factors can increase the risk of these clots, including prolonged bed rest (such as after surgery), sitting for long periods (such as on a plane), use of birth control pills or hormone replacement therapy, pregnancy, family history of DVT, inflammatory bowel disease, and certain genetic clotting disorders. Compression stockings are also sometimes used in people who have an acute DVT, to prevent a group of symptoms known as post-thrombotic syndrome that includes leg pain and

Deep Vein Thrombosis (DVT), is a blood clot that forms in a deep vein inside the body. DVT can occur when the blood thickens, because the thickening of the blood can cause a clot to form. DVT will generally occur within the lower leg or thigh, as well as other parts of the body. A clot that occurs in a deep vein can possibly break off from the original vein. When it breaks off it can travel throughout the body’s bloodstream. It is called an embolus when the clot breaks off. The clots that broke off throughout the thighs, are more likely to cause Pulmonary Embolism, rather than the other blood clots within the remainder of the body. Pulmonary Embolism is a serious condition which can be caused by blood clots. It can damage your organs, more likely to be the lungs, and cause death of an individual.
Breast cancer is most commonly diagnosed in Stage I and Stage II, where the size of the tumor is less than five centimeters in diameter. In these situations, surgery is often the second treatment option after chemotherapy and radiation therapy, both of which are used to shrink the tumor to a manageable size first. If the patient chooses to, the ...
Chemoprevention requires treatments that are administered to presumably healthy, asymptomatic subjects who do not have cancer, but do have risk factors associated with an increased probability to cultivate the cancer which the experimental intervention is theorized to condense. So, chemoprevention research involves at-risk research subjects who are neither patients diagnosed with disease, as in treatment trials, or typical healthy volunteers. There is a growing interest and investment in research on cancer chemoprevention. Several major cancer chemoprevention trials have been conducted in the United States, including trials testing the effectiveness of tamoxifen, both alone and later compared to raloxitene, to prevent primary invasive breast cancer; finasteride to prevent prostate cancer; and beta-carotene to prevent lung cancer.
The American Cancer Society’s main concern is assisting people, making profits come second. The American Cancer Society helps patient’s life by finding cures. “For over 100 years, the American Cancer Society (ACS) has worked relentlessly to save lives and create a world with less cancer. Together with millions of our supporters worldwide, we help people stay well and get well, find cures, and fight back against cancer” (American Cancer Society, 2015a). Many people in this world see the importance of the organization and find the interest in donating money or providing anything to help the cause.
Studies have shown that birth control can cause an increase of blood clots (also known as venous thromboembolism, or VTE), especially the newer forms of birth control (oral contraceptive) such as the the NuvaRing. British Medical Journal cited in the Vanity Fair article concluded that the risk of getting a blood clot is 6.5 times greater when using some sort of contraceptive. Without birth control about 2.1 women out of 10,000 will get a blood clot each year. When women use oral contraceptive the number rises to 6.2 out of 10,000. When using the NuvaRing the number jumps to 7.75 out of 10,000. Even though there is a risk for blood clots, the study did not consider pertinent external variables including smoking, obesity, and family history (Gueren, 2013).
More research should be done on new oral anticoagulants with different study population and similar patients that are seen in everyday clinical practice as well as attempt to define the best pharmacodynamic monitoring tools. Research should be conducted to outline monitoring protocol including timing relative to dosing and frequency as well as therapeutic targets. Using these strategies, future trials could enhance further the efficacy and safety of these new agents and could extend their use to new indications.
The risks of getting cancer in this day and age has been increasing at a rate that could be detrimental to the human race if we do not act now. It is scary to think that you or someone you love and care about will get some type of cancer in their life time. Although there are many different types of cancer that is in existence today, the main focus is breast cancer. We are going to explore the causes breast cancer, the stages, how we can treat it and what precautions that can be taken to help lower ones risk of getting breast cancer. In America a baby girl born today has a 1 in 8 chance of getting breast cancer sometime in her life. These statistics do not seem so scary until they are put into perspective. Every three minute a woman is diagnosed with breast cancer and one will die every 13 minutes in a given day. If these rates of breast cancer continue to rise there will soon be a one in one baby girl born that will et diagnosed with breast cancer. This is the future of our world that we are talking about here and no one seems to be changing the main factors that contribute to breast cancer. There are many different suspicious causes but one thing that is clear is that an unhealthy environment has an enormous impact on women and their development from babies to women.
Breast Cancer is defined as “a group of solid tumor malignancies arising in the tissues of the breast” (Sarah Crawford, Richard Alder, 2013) in human and other mammals. It can happen to both men and women. For women, breast cancer is one of the leading causes of cancer death. According to National Cancer Institute, in the United States, the 2014 estimated new cases and deaths of female from breast cancer are 232,670 and 40,000, respectively. For male, it’s 430 deaths out of 2,360 new cases. From these numbers, we can see that women in the U.S. are greatly affected by breast cancer, thus, it’s not difficult to imagine the impact on a worldwide level. Although these numbers look frightening, people can actually survive from breast cancer if it is detected early and treated properly, so it is extremely important for all of us, especially women, to have a better understanding of breast cancer.
25% of the deaths h in 1991 and is the most common cause of death
An ordinary human body contains approximately one trillion cells and precisely 46 chromosomes in each cell. However, the human body can be altered by a genetic mutation. Over the course of history, genetic mutations have had a large impact on the human race. They have brought harm to numerous amounts of people. Cancer, in particular, is one of the most lethal diseases. Cancer begins when a portion of DNA inside a chromosome is damaged, causing a cell to mutate. Then, the mutated cell reproduces multiple times and creates a tumor. Afterwards, cancer cells break off of the tumor, enter the bloodstream, and disperse throughout the body. If the cells break off, the tumor is considered malignant - this type of cancer is very difficult to cure. Many patients today stay optimistic for a medication to heal cancer. It is imperative to address a few of the causes and effects of cancer in order to gain a general knowledge of genetic mutations.
Dosing regimens and drug combinations were selected empirically and this is due to several challenges.[7, 8] First, most protocols utilise drug combinations and each drug has a different mechanism of action. Secondly, dose optimisation has not been established because low-dose protocols aren’t defined by dose-limiting toxicities. Finally, clinically applicable biomarkers of tumour response are yet to be established.[23]
Huether & Mccance (2017) “A thrombus is a blood clot that remains attached to a vessel wall. A detached thrombus is a thromboembolus. Venous thrombi are more common than arterial thrombi because flow and pressure are lower in the veins than the arteries”. Individuals might be asymptomatic with this disease. “Accumulation of clotting factors and platelets leads to thrombus formation in the vein, often near a venous valve. Inflammation around the thrombus promotes further platelets aggregation, and the thrombus propagates or grows proximally” Huether & Mccance (2017). On most occasions there are no clinical signs or symptoms of deep vein thrombus. However, some patients may experience pain, swelling, and redness in the area of the thrombus. “Deep vein thrombosis can develop if you have certain medical conditions that affect how your blood clots. Deep vein thrombosis can also happen if you don't move for a long time, such as after surgery, following an accident, or when you are confined to a hospital or nursing home bed” Mayo Clinic (2014).There are several factors that put individuals at high risk for deep vein thrombosis such as immobility, age, and congestive heart failure, trauma, pregnancy, inherited disorders, and hormone replacement therapy. No necessary treatment may be required to treat deep vein thrombosis. On the other hand, if the clot doesn’t dissolve on its treatment is required to prevent part of the clot traveling to patient’s lungs or other parts of the patient’s body. The D-dimer test and a Doppler exam is performed to adequately diagnose a patient. Anticoagulants are the treatment of choice for individuals that require
The East Pennsboro elementary school raised money for a statue at a local park. The statue was a ring of children that were holding hands. There was one child missing; the link was broken. The statue was dedicated to East Pennsboro students that did not make it to their graduation. My sophomore year of high school inspired this piece of artwork.
