More than 1 in 3 people in the UK will develop some form of cancer during their lifetime (1). This shows how important treating cancer is, in the best way possible.
Cancer is a disease caused by an uncontrolled division of abnormal cells in a part of the body. Cancer cells have certain traits, they divide rapidly by stopping the dividing signals, they move to different organs, become immortal since no tumour suppressor gene to tell when the cell needs to die. In addition, cancerous cell also creates their own blood vessels for oxygen and nutrients which is essential for the growth of the cell and is also known as angiogenesis. There are various ways of treating this, one is through localised treatment; surgery where you work on the cancerous areas of the organ. Another localised treatment is radiotherapy which beams gamma rays or x-rays used for the cancer treatment (1). Chemotherapy is also a conventional treatment of cancer; this is a systemic type of treatment this means that it goes all around the body, and has certain drugs which stop the process of cancer cells from developing. For example the cyclophosphamide drug binds the DNA during replication of the DNA. However this has many side effects because it is systemic, it also targets the other rapidly dividing cells like the red blood cells which explain the side effects of having anaemia (2). A solution to this problem would be to create specific drugs for that cancer cell; through personalised medicine. Personalised medicine means tailoring a medicine specific to the patient depending on their cancer’s genetic makeup, using antibodies is a type of this. Another form of personalised medicine is by using magnetic Nano-particles to make the treatment more localised to act as...

...treat this cancer I would use antibody to EGFR attached to nanoparticles and inject it in the cancerous area. The nanoparticle consists of iron oxide and use the iron particle in an alternating magnetic field. This field will generate heat, and cause the cancer cell to burst.
This will reduce the size of it and most important will be a localised treatment thus the antibody can recognise the cancer cell and cause fewer side effects in comparison to the conventional way. Unfortunately some side effects can still occur; one of the main factors is that the nanoparticles injected can spread to the normal, healthy cells causing damage and side effects like headaches. However it is still more effective because in conventional therapy all parts of the body is effected like hair loss, fertility loss etc. But this is much more localised making it much more effective (25).
Personal health is extremely important to everyone around the world. But it is especially important to citizens of the United States of America. Being one of the leading countries in Health technology and also in food and beverage leaves most people choosing between living a healthy lifestyle and indulging in the varieties of food we offer. Across the country, many people are living with pre-existing conditions, living in food deserts, living below the poverty line and a long list of other factors that either hinders them from eating healthy or force them to eat healthily. When trying to live a healthy lifestyle in this country not only does the promotion of prevention matter, but also the promotion of Career and job opportunities matter just as much. In the United States, Money equals Power and money also equal the opportunity to create and live a healthier lifestyle.
Cancer is one of the 9 National Health Priority Areas (NHPA), areas which account for a significant portion of the burden of disease, but have sizeable potential for improvement. In Australia, CRC is the second most common cancer, after prostate (in men) and breast cancer (in women) (AIHW, Cancer incidence projections). The incidence has gradually increased (by 13% in males from 1982-2007) (AIHW, Cancer in Australia an overview). This is compounded by the ageing population and population growth, with 14,860 new cases in 2010 (http://www.cancer.org.au/about-cancer/types-of-cancer/bowel-cancer). This graph demonstrates this upward trend ((AIHW, Cancer incidence projections):
Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.
For cancer patients there are several treatment options. Surgery can remove cancerous tumors, chemotherapy uses drugs for treatment, and radiation therapy. The doctor in charge of the patient’s treatment may also choose to use radiation therapy. “Radiation
Cancer. The word by itself can conjure images of severely ill and frail people attached to IV medications and chemotherapy drugs as they cling to life in a hospital bed. Other illustrations and pictures depict unrecognizable, misshaped organs affected by abnormal cells that grow out of control, spread, and invade other parts of the body. Cancer studies show that close to one-half of all men and one-third of all women in the United States will be diagnosed with cancer during their lives. Today, millions of people are living with cancer or have had cancer. As patients are newly diagnosed with their specific type of cancer, whether it be breast, lung, prostate, skin, or blood cancer, etc., each patient has to consider what will happen with their future health care plan and who will be involved in their long journey from treatment to recovery. Once diagnosed, cancer patients become the focal point and the center of all activity in terms of care but cancer not only physically invades the patient’s body and well-being, it goes beyond the patient and significantly affects the emotional stability and support from from their loved ones and caregivers. Based on the insidious nature of cancer and typically late detection of malignant diseases, family members (either spouses, children, parents, other relatives, and friends) often become the patient's main caregiver. These caregivers, also known as informal caregivers, provide the cancer patient with the majority of the support outside of the medical facility or hospital environment and become the primary person to provide various types of assistance. They provide the physical support with bathing and assisting in activities of daily living, they become emotional ...
Chemotherapy is the use of chemicals to cure cancer. Chemotherapy is also known as “chemo”. The term for chemo came from the German bacteriologist Paul Ehrlich around the year 1900. He came up with the term when he was examining aniline dyes and arsenicals as possible treatments for diseases such as syphilis. He envisioned “magic bullets” that would be able to target invading organisms but still leave the host unscathed. This goal has been providing therapeutic benefits without many side effects in all areas of drug development. There has been a lot of success with compounds that modulate normal biochemistry within the body.
A cancer diagnosis can significantly change your life and the lives of your family in various ways. Hearing the news “you’ve been diagnosed with cancer” leave patients and their families in a whirlwind of emotions. The initial shock of this diagnosis leaves feelings of sadness, denial, frustration, confusion, fear, anger, and often times the “why me?” feeling. Thoughts start going through your head regarding how this affects yourself, your family, and your everyday life.
Glucose is a sugar that plays a big part in a human’s health and well-being. This sugar is a major source of energy for the body’s brain and cells. The Cells that receive energy from glucose help in the building of the body’s muscle and tissue. Although glucose may be important to the body too much of this sugar can cause a chronic condition called Diabetes. Diabetes, also known as Diabetes mellitus, is a chronic condition that is caused by too much sugar in the blood. This condition can affect all age groups. In fact, in 2010 a survey was taken by the National Diabetes Information Clearinghouse, on the number of newly diagnosed diabetes. Out of 1,907,000 people: 24.38% were ages 20-44, 55.17% were ages 45-64, and 20.45% were ages 65 and greater. Diabetes is a very serious condition, and it can be deadly if left untreated. This paper will help better educate the reader on the signs and symptoms, the testing process, and the management of diabetes.
Over the years, our scientists and doctors have made a substantial amount of progress. As we prepare for the future, we must wonder if we will have enough doctors, nurses, and researchers who specialize in cancer. Even though we know a great deal about Biology, we will always continue to uncover new knowledge in the future. Hopefully our knowledge of Biology will help scientists and researchers to develop new cancer screening methods and cancer drugs that will be effective against cancer. An ideal solution would to be able to figure out how to destroy cancerous cells without them returning or spreading to other areas of the body, and without killing off healthy cells. Our knowledge of cancer is still expanding, and will continue to over the years to
Late December 2015 was, at the time, the worst month for me. It was around 8'o clock in the evening, the sun had set and the moon has risen to its’ fullest. I could smell the sweet aroma from the kitchen. I walked passed and into the living room, which was messy from all of our christmas decor. My mom yelled down the hall to my brothers.
Cancer is a disease that affects human somatic cells. It causes the cells to divide uncontrollably and form masses known as tumors. There are two different types of cancer tumors. Some tumors are benign and other tumors are malignant. 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. Over the past few decades cancer has become a very prominent disease. There are many different types of cancer and many different causes for the the disease. Most cancers are because of a genetic mutation. The most common type occur when a cell is dividing. Proto-oncogenes, which are alleles in a normal cells, mutate to form oncogenes. These oncogenes cause cancer because they do not allow the cells to self destruct or become epistatic. There have been several research projects which have been testing epistatis.
Bioengineering analysis is pointing a new way to better drug designs and better drug testing. The disease of cancer has taken the life of many patients, but through new medicines and procedures many more are surviving. A significant progress has been made against cancer, allowing people to live longer and fuller lives. There have been more than one-million less cancer deaths since 1990and 1991(aacr.org). On January 1, 2012 there were 13.7 million survivors in the United States. These numbers are achieved by using new techniques to cure cancer like, immunotherapies to avoid toxins, Targeted cancer therapies to target different types of cancer, and weakling cancerous tumors making them susceptible to drugs. Cancer is still a significant problem and is far from being cured, but step by step biomedical engineers are getting closer and closer.
Cancer is the uncontrolled growth of abnormal cells in the body. Tumors are then created and interfering with the digestive, nervous and circulatory systems. It is one of the most leading causes of death, reaching at about 8.2 million deaths in 2012. It is expected that cancer will rise from 14 million to 22 million within the next 2 decades. With over 100 cancer research centers in the United States studying how to treat this disease, people need to understand the importance of donating also with the awareness of signs and symptoms in the early stages. But, what are we doing about it? Do we have the technology to finally be able to put this deadly disease to an end?
Diabetes mellitus is a group of metabolic disorders which is characterized by hyperglycemia due to insulin deficiency or resistance or both reasons. (1) According to that diabetes mellitus can be divided as type I and type II. This is common and its incidence is rising, 171 million people had diabetes in 2000 it is expected this condition to be doubled in 2030. It is spread in all the countries and therefore has become a major burden upon healthcare facilities. (2)
Diabetes mellitus refers to a group of diseases that affect how your body uses blood glucose, commonly called blood sugar. Glucose is vital to your health because it's an important source of energy for the cells that make up your muscles and tissues. Glucose comes from two different sources, your liver and food. It's also your brain's main source of fuel. Glucose is made and stored in the liver. When your blood sugar gets low then your liver will use the stored glucose to keep your blood sugar level normal. If you have diabetes it means you have too much glucose in your blood. This is where insulin comes in. Diabetes is a growing epidemic in America's many nutritional diseases. There are a few factors that can cause or increase a person's chance of getting diabetes. Poor nutritional choices are a big factor in the cause of diabetes. The sad part is the increase is happening to the young children and teenagers in America. I will talk about what diabetes is, the increase in diabetes and why it’s so high, the complications that follow the diagnosis, and how it can be treated or reduced with diet and exercise.
