Introduction
The origin of the word cancer is credited to the Greek physician Hippocrates, who is considered to be the Father of Medicine. One out of every two men and one out of every three women will be diagnosed with cancer, but despite those huge numbers most individuals does not know what that really means.
Cancer is when abnormal cells divide in an uncontrolled way and develops when the body’s normal control mechanism stops working. Cancer cells are different than normal cells in many ways that allow them to develop out of control and become invasive. Normal cells mature into distinct cell types with particular functions and cancer cells do not. Unlike normal cells, cancer cells continue to divide without stopping. Many cancers form solid tumors, which are masses of tissue. Tumors can be malignant or benign. Unlike malignant tumors, benign tumors do not invade tissues that are near. Cancerous tumors are malignant, which means these tumors invade tissues. A cancer that has spread from where it started to other places in the body is called metastatic cancer. The process is called metastasis. Treatment may help prolong the lives of some people with metastatic cancer. There are many types of cancer treatment. The types of treatment that a patient receives will depend on the type of cancer that they have and how advanced it is. The main types of treatment are surgery, radiotherapy, hormone therapy, chemotherapy and bone and stem cell transplants.

Cancer is a defined as a group of cells in the body that begin to divide without stopping and
The CDC estimates that each year, more than eight million people are diagnosed, and consequently died from cancer, and this statistic was even higher in the 1950s. During this period, little was known of cancer’s effects on the
When first considering cancer treatment plans, it helps to understand your general options. Types of cancer treatment can be categorized into four modalities: Medical, surgical, radiation, and chemotherapy. Examples of medical options include chemical medicines, immunotherapy, and biological/endocrine therapy. Many surgical options can be minimally invasive and utilize modern technologies to better suit the patient's personalized treatment plan. While you may have heard of radiation and chemotherapy, you may not realize the recent advancements that improve these therapies, creating healthy, successful outcomes every day.
Cancer is defined by the National Cancer Institute as ?the title given to a group of related diseases. All types of cancer are categorized by uncontrollable growth of cells that metastasize to surrounding tissues.? Cancer can develop at almost any part of the human body and anyone can develop cancer, although risk typically increases with age because most cancers tend to require many years to develop. ?Typically, human cells tend to grow and divide and ultimately form new cells as the body needs them. When an organisms cells grow old or get damaged, the cells die, and new ones replace them. However when cancer
A cancer cell is formed when the cell’s DNA is damaged but not repaired. Instead of the cell dying, like a normal cell, it reproduces new cells which also have the damaged DNA that the original cell had. Factors that can cause a cell to be damaged are mistakes during the reproduction of the cell, environmental reasons, such as smoking or too much sun exposure. The cancer cells form tumors which then invade the tissue of a certain body part, like the breast, lungs, brain, or prostate. Cancer can spread sometimes from body part to body part, but is named from where it starts. For instance, if somebody were to be diagnosed with breast cancer, and developed cancer in their lungs, it would be metastatic lung cancer. Metastasis is how cancer can spread to other body
Harmful tumors require quick regulation and treatment, as threatening developments may grow quickly and metastasize (spread all through the body) at a disturbing rate. Metastases are auxiliary tumors which can show up at any area all through the body, which is an immediate impact of disease spreading by means of blood and lymph hubs.

When an organisms cells grow old or get damaged, the cells die, and new ones replace them. However when cancer develops, this orderly process gets reformatted. As cells increasingly get more irregular, old or damaged cells begin to survive when they should die, and new cells develop in the body when there is no need for them. These abnormal cells have the ability to divide without stopping and tend to result in growths called tumors?(cancer.gov). Cancerous tumors are defined as malignant meaning that they can spread to nearby tissues or metastasize to distant places in places within the body and form new cancerous tumors. There are over 100 forms of cancer and they are usually named after the organs or tissues where the cancers originate. Staging of cancer is used when describing the severity of a person?s cancer and is based upon the following
Chemotherapy can be used as the essential treatment of therapy or alongside other treatments of
First, we must understand what cancer is and how it forms, cancer is “a malignant and invasive growth or tumor, especially one originating in epithelium, tending to recur after excision and to metastasize to other sites.”1 it is when normal cells mutate and begin to reproduce at such an accelerated rate that body does not have time to get rid of these bad cells and a mass begins to grow creating a problem for the body.
Cells are constantly getting instructions from chromosomes to divide. Cancer forms when cells get instructions incorrectly and begin dividing too much and cells do not get a message to stop making cells so they continue to divide. When cells grow out of control, a tumor forms. A tumor that is malignant does spread.
There are a wide variety of cancer types. They all have several things in common, however. Each cancer starts with cells that become abnormal or cancerous. These cells reproduce and form a mass of cancerous cells. This mass is called a tumor. When the cancerous cells spread, or metastasize, they can impact other tissues, organs, and systems of the body. A second commonality among cancers is that when they are detected early, they are easier to treat and the treatments are more likely to work. In many cases, a cancer that is caught early can be completely destroyed.
After the person becomes an adult, most cells divide only to replace worn-out or dying cells to repair injuries (“What is Cancer?” American Cancer Society). When cancer develops, this orderly process is broken down. As cells grow to be more and more abnormal, old or damaged cells survive when they should die. New cells form when they are not needed. Cancer cells come to be cancer cells because of variations, or mutations, to their DNA. In the cancer cells, damaged DNA is not restored, but the cell doesn’t die like it should. Instead, the cell goes on constructing new cells that the body doesn’t require. These new cells all have the same damaged DNA as the first cell does (“What is Cancer?” American Cancer Society). These cells may form growths termed tumors (“What is Cancer?” National Cancer Institute). Cancer cells are also able to disregard signals that routinely tell cells to halt dividing or that begin a process referred to as programmed cell death, apoptosis, which the body uses to get rid of unneeded cells. Cancer cells may be able to influence the normal cells, molecules, and blood vessels that frame and nourish a
Cancer is defined by the National Cancer Institute as “the name given to a collection of related diseases. In all types of cancer, some of the body’s cells begin to divide without stopping and spread into surrounding tissues.” Cancer can develop at almost any part of the human body and anyone can develop cancer, although risk typically increases with age because most cancers tend to require many years to develop. “Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place. When cancer develops, however, this orderly process breaks down. As cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed. These extra cells can divide without stopping and may form growths called tumors” (cancer.gov). Cancerous tumors are defined as malignant meaning that they can spread to nearby tissues or metastasize to distant places in places within the body and form new cancerous tumors. There are over 100 forms of cancer and they are usually named after the organs or tissues where the cancers originate. Staging of cancer is used to “describe the severity of a person’s cancer based on the size and/or extent (reach) of the original (primary) tumor and whether or not cancer has spread in the body” (cancer.gov). The importance’s of staging cancer is to assist the doctor with planning appropriate treatments to fight the cancer
Several methods such as surgery, radiation, and chemotherapy have been used to treat cancers. The cancer patients who are not helped
Doctors have come up with the treatment of Chemotherapy. Chemotherapy is a toxic mix of drugs that they say can “cure” cancer. It is the leading “treatment” for cancer as of today. The typical patient spends almost $50,000 on
