What is a group of diseases characterized by uncontrollable growth and spread of abnormal cells?

The American Cancer Society defines cancer as “a group of diseases characterized by uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death.”

What is a group of diseases characterized by uncontrolled growth and spread of abnormal cells in the body and can cause internal and external factors?

According to the ACS, cancer is a group of diseases characterized by uncontrolled growth and spread of abnormal cells. If the spread is not controlled, it can result in death.

What term is used to describe the uncontrolled growth and spread of abnormal cells?

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 is a group of uncontrollable cells called?

Cancer begins when genetic changes interfere with this orderly process. Cells start to grow uncontrollably. These cells may form a mass called a tumor. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can grow and spread to other parts of the body.

Which disease is the result of uncontrolled cell growth?

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Which disease is characterized by the rapid growth of abnormal cells in the lungs?

lung cancer, disease characterized by uncontrolled growth of cells in the lungs. Lung cancer was first described by doctors in the mid-19th century.

What is a fundamental difference between normal and cancerous cells?

Normal cells are either repaired or die (undergo apoptosis) when they are damaged or get old. Cancer cells are either not repaired or do not undergo apoptosis. For example, one protein called p53 has the job of checking to see if a cell is too damaged to repair, and if so, advise the cell to kill itself.

How do cells become cancerous?

Cells become cancerous after mutations accumulate in the various genes that control cell proliferation. According to research findings from the Cancer Genome Project, most cancer cells possess 60 or more mutations.

How does a cell become cancerous?

What is a word for cancerous?

Malignant (muh-LIG-nunt): cancerous. Malignancy is another word for cancer. Metastasis (meh-TAS-tuh-sis): the spread of cancer from one part of the body to another.

What diseases are caused by cells?

Cancer, ciliopathies, Alzheimer’s and Parkinson’s are some of the many diseases associated with defective cell transport.

What is the spread of abnormal cells from one part of the body to another?

The spread of cancer cells from the place where they first formed to another part of the body. In metastasis, cancer cells break away from the original (primary) tumor, travel through the blood or lymph system, and form a new tumor in other organs or tissues of the body.
