Cancer is a fascinating area in biology, especially because of its ability to affect the whole body. Researching and learning about cancer involves learning about cells, the immune system, genes, tissues, and the entire body system. Learning about cancer leads to a better understanding of the affected body parts, especially the importance of growth and replication of body cells. Cancer has had a massive impact on medicine. It has led to increased research in the field, which has contributed to a better understanding of the disease. It has led to the innovation of medical tools aimed at detecting and treating it. There has been an increase in cancer screening and diagnosing tools. The tools have been improved to reduce the side effects and the results. For instance, a while back, using radiation as a treatment method meant that even the healthy cells were destroyed in the presence. This has changed as the treatment method has become more effective at targeting the affected cancer cells only. The presence and spread of cancer has led to the development of multiple drug varieties, aimed at treating different types of cancer. The new drug varieties have improved qualities, and they have reduced and more manageable side effects. For instance, researchers are able to determine the effect of drugs using vertically integrated multiscale models, with quantified biomarkers (Cesario and Marcus 18). It has led to the development of new treatment methods and therapies. New medical technologies have led to the development of personalized and system medicines.
Physicians, other health providers, different government and non-governmental organizations have embarked on campaigns intended to inform people about cancer. They educate the people concerning different types of cancer, and they teach them how to avoid getting cancer. People can undertake several measures to reduce their chances of getting cancer. Many of these factors involve observing healthy lifestyles. Some of these measures include quitting smoking, losing and maintaining a healthy weight, reducing the consumption of alcohol, and avoiding exposing oneself to direct sun without the necessary protection. Diet plays an important role in cancer prevention. This is because some of the foods consumed increase the chances of a person developing cancer, while others reduce the chances of getting cancer. About 35% of cancer deaths are caused by unhealthy eating habits (Kwabi-Addo and Indstrom 115). Avoiding artificially made foods or foods high in salt and fat will reduce the chances of cancer, and so will consumption of a healthy diet rich in fruits and vegetables. Some foods such as leeks, garlic, chives, tomatoes, onions, and foods rich in vitamins, zinc, calcium, and folate, help in cancer prevention (Kwabi-Addo and Indstrom 119). Physicians recommend screening, which will detect the presence of tumors at an early stage. Conducting mammograms, self-examination of the breast and the testicles, and pap smears are some of the methods used to screen for cancer.
However, only about 25% of the breast cancer cases got explained (Brody et al.); till today, heredity, lifetime exposure to environmental estrogen (the female sex hormone), and the dietary fat are the only major known causes (“Cover Story: Breast Cancer and Environment”)....
In other words it takes a woman 3 months if not longer to inform her doctor that she might have breast cancer or some other problem wrong with her body.
Factors associated with developing breast cancer that cannot be influenced include: gender, age, family history, benign breast problems, and menstrual problems (in text).
Breast cancer is a very serious disease that shouldn’t be taken lightly; if it is left untreated it can spread to other organs and eventually kill you. Even if you do not have breast cancer, chances are that you know or will know someone who will get it, so it is imperative that people understand how breast cancer forms, know the stages of breast cancer, be familiar with who gets breast cancer and how you can possibly avert it, and understand all of the different ways to treat the cancer and...
There are several options that the physician can consider when determining the treatment. The physician has to consider several factors before determining the treatment. These factors include the type and spread of cancer, the stage of the cancer, the patients’ age, and the patients’ health status. These factors help to determine the success of the treatment. In many cases, the physician uses a combination of treatments. Many cancer patients require surgery, which they use in combination with other treatment methods such as radiation and chemotherapy, depending on the level of the cancer (Kumar 1). The physician does not have to use all the treatment methods. In some cases, the surgery rids the person off cancer when the physician removes the tumor. Physicians also use hormone therapy and immunotherapy methods to treat cancer. The treatment methods used do not guarantee the patients’ recovery, and some patients end up dying.
Detection of cancer at an early stage is beneficial because it increases the chances of recovery after treatment. Other than the symptoms, the physician will also use other methods to detect the presence of cancer in the body. These methods include various imaging techniques such as different types of scans, which are used depending on the location of the problem, and x rays. The imaging techniques help in locating the presence of a tumor in the body. The physician has to perform a biopsy to ensure with certainty that the cells extracted are cancerous. After detecting the cancer, the physician has to check if the cancer has spread to other parts of the body, and determine the degree of infection. Cancer happens in different stages, and the physician uses these stages to determine the treatment to use.
It is known that it is the most commonly triggered by vigorous amounts of sunshine, over excessive use of tanning bed and UV lights which result in making mutations in the skin that produces the skin cells to over multiply at a quick rate which can eventually form nasty tumours.
There are different causes of cancer. These include different types of carcinogens, which promote the development and advancement of different types of cancers. The carcinogens encourage the formation of free radicals, which damage the cells. Carcinogens include chemicals such as benzene, asbestos, and arsenic, tobacco, and radiation from x rays and gamma rays. Different types of viruses can also cause cancer. For instance, the human papillomavirus (HPV) has been linked to cervical cancer, while hepatitis B and C have been linked to liver cancer. Factors such as obesity are high risk factors of developing cancer.
The aim of this study was to determine the putative colon cancer stem cell subsets in human colon cancer cell lines HCT116 and HT29, which differ in their aggressiveness and differentiation capacity....
A person develops cancer when his cells grow uncontrollably. In normal body functioning, the cells grow as the body needs them, and they die when not in use. Cancer occurs when the cells do not die, but they continue the process of growth and division. The damaged cells form tumors, which, when they grow, interfere with the functioning of some of the main body systems. Tumors can be benign, meaning they are non-cancerous, or they can be malignant. Tumors can spread to other parts of the body, where they can damage the body cells and tissues. Since cancer grows out of body cells, it can affect any part of the body organs or tissues.
