CAN YOU PLEASE HELP ME WITH SOME RESEARCH??? GOOD ANSWERS WILL GET BRAINLIEST!!! What is cancer? Is cancer only one disease?
How does cancer affect the cell cycle and the growth of cells? How is this process similar to or different from how an infectious disease affects cells?
How do genes play a role in cancer progression?
Are there any environmental or pathogenic factors that can cause cancer?
How does cancer progress in the body? Why is cancer difficult to treat in the later stages?
What do the terms stage and grade mean in the context of cancer?
What current treatments exist for cancer?
What treatments are on the horizon?
What are the challenges of treating or curing cancer?

Cancer is the uncontrolled growth of abnormal cells anywhere in a body.

There are over 200 types of cancer.

Anything that may cause a normal body cell to develop abnormally potentially can cause cancer; general categories of cancer-related or causative agents are as follows: chemical or toxic compound exposures, ionizing radiation, some pathogens, and human genetics.

Cancer symptoms and signs depend on the specific type and grade of cancer; although general signs and symptoms are not very specific the following can be found in patients with different cancers: fatigue, weight loss, pain, skin changes, change in bowel or bladder function, unusual bleeding, persistent cough or voice change, fever, lumps, or tissue masses.

Although there are many tests to screen and presumptively diagnose cancer, the definite diagnosis is made by examination of a biopsy sample of suspected cancer tissue.

Cancer staging is often determined by biopsy results and helps determine the cancer type and the extent of cancer spread; staging also helps caregivers determine treatment protocols. In general, in most staging methods, the higher the number assigned (usually between 0 to 4), the more aggressive the cancer type or more widespread is the cancer in the body. Staging methods differ from cancer to cancer and need to be individually discussed with your health care provider.

Treatment protocols vary according to the type and stage of the cancer. Most treatment protocols are designed to fit the individual patient's disease. However, most treatments include at least one of the following and may include all: surgery, chemotherapy, and radiation therapy.

There are many listed home remedies and alternative treatments for cancers but patients are strongly recommended to discuss these before use with their cancer doctors.

The prognosis of cancer can range from excellent to poor. The prognosis depends on the cancer type and its staging with those cancers known to be aggressive and those staged with higher numbers (3 to 4) often have a prognosis that ranges more toward poor.

Explanation:

Simply put, cancer is the result of unregulated cell division. Cancer cells divide when they are not supposed to, don't stop dividing when they are supposed to and don't die when they should. In the worst cases, the cancer cells leave the area in which they arose and travel to other parts of the body.

Cancer cells do not look or act like the normal cells from which they originate. It is reasonable, then, to ask 'Why do cancer cells behave so badly?'. It turns out the the answers lie in the genes of the affected cells. In cancer cells, changes to key genes cause the cells to act abnormally. The changes are often the result of changes to the DNA (mutations) in the cells. Because there are many different things that are capable of causing mutation, there are an equally large number of causes of cancer.

The development of cancer takes place in a multi-step process. As the cells become more abnormal, they gain new capabilities, such as the ability to release growth factors and digestive enzymes. The cells continue to divide, impacting nearby normal cells, often reducing the function of the affected organ. Even abnormal cancer cells die sometime and a tumor that is large enough to feel can take years to reach that size. Although not all cancers share exactly the same steps, there are some general features that are shared in the development of many types of cancer. Further information on the topics on this page can also be found in most introductory Biology textbooks, we recommend Campbell Biology, 11th editionIn the eighteenth century, London physician Percival Pott made the first link between cancer and environmental agents when he noted a high incidence of scrotal cancer among chimney sweeps. He hypothesized that it was caused by exposure to coals and tars. Out of this observation grew the two-stage model of cancer development by 1) initiators and 2) promoters. In the years since Pott's observations a wide range of chemicals, radiation sources, viruses and bacteria have been implicated in the development of cancer. 2
