What is cancer based on?

Cancer is caused by certain changes to genes, the basic physical units of inheritance. Genes are arranged in long strands of tightly packed DNA called chromosomes. Cancer is a genetic disease—that is, it is caused by changes to genes that control the way our cells function, especially how they grow and divide.

Why is it important to find a cure for cancer?

The most important aim of cancer treatment is to achieve cure and secondly to palliate (life prolongation and relief of sufferings) where cure is not possible due to advanced disease. Nowadays, 30\% of all cancers are routinely cured.

What is the study and treatment of cancer is called?

Clinical trials, also called research studies, test new treatments in people with cancer. The goal of this research is to find better ways to treat cancer and help cancer patients.

What is cancer in its most basic form?

Common Cancer Types

What is cancer and how does it form?

Cancer is the uncontrolled growth of abnormal cells in the body. Cancer develops when the body’s normal control mechanism stops working. Old cells do not die and instead grow out of control, forming new, abnormal cells. These extra cells may form a mass of tissue, called a tumor.

What are the aims of cancer treatment?

The goals of cancer treatment include eradicating known tumors entirely, preventing the recurrence or spread of the primary cancer, and relieving symptoms if all reasonable curative approaches have been exhausted. Decisions concerning how to treat a particular cancer are based on many factors.

Which is used in treatment of cancer?

Some people with cancer will have only one treatment. But most people have a combination of treatments, such as surgery with chemotherapy and/or radiation therapy. You may also have immunotherapy, targeted therapy, or hormone therapy.

How many types of treatment are there?

Three principal types of medical treatment Curative – to cure a patient of an illness. Palliative – to relieve symptoms from an illness.

What is cancer mean?

(KAN-ser) A term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems.

What pathophysiology means?

Definition of pathophysiology : the physiology of abnormal states specifically : the functional changes that accompany a particular syndrome or disease.

What is etiology and pathogenesis?

Etiology answers to the initial questions about the disease. Pathology or Pathogenesis is the detailed explanation as to how the disease affected the patient in question. Once etiology of a disease is confirmed, pathology deals with the mechanism of action of the risk factor.

What causes cancer cells to grow out of control?

Oncogenes: These genes cause cells to grow out of control and become cancer cells. They are formed by changes or mutations of certain normal genes of the cell called proto-oncogenes.

Why is research important in cancer research?

Today, research is discovering new carcinogens, explaining how they cause cancer, and providing insight into ways to prevent cancer. By the middle of the 20th century, scientists had the instruments they needed to work on some of the complex problems of chemistry and biology that remained unsolved.

How does cancer affect patient engagement in health care decisions?

The emotional, financial, and logistical repercussions of a cancer diagnosis and the complexity of treatment options, together with patients’ limitations in health literacy and lack of experience with the health care system, can make it difficult for patients and their families to actively engage in making health care decisions.

What makes a high-quality cancer care delivery system?

The committee’s conceptual framework for a high-quality cancer care delivery system highlights the critical importance of engaged patients. Patients are at the center of the framework (see Figure S-2), which conveys the most important goal of a high-quality cancer care delivery system: meeting the needs of patients with cancer and their families.
