Cancer and Sunken Eyes Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant.

The vet says my cat has a tumour â is it cancer? The language surrounding cancer can be confusing and definitions are difficult. Tumours (also called growths) can be cancerous or non-cancerous, depending on what they do within the body. A tumour is the uncontrolled growth of microscopic body components (known as cells).

Frankly Speaking About Cancer: Brain Tumors A brain tumor is an abnormal growth of tissue in the brain or central spine that can disrupt proper brain function. Doctors refer to a tumor based on where the tumor cells originated, and whether they are cancerous (malignant) or not (benign). 1  Benign: The least aggressive type of brain tumor is often called a benign brain tumor.  Malignant: Malignant brain tumors contain cancer cells and often do not have clear borders.

Medical Definition of Tumor Tumor: An abnormal mass of tissue. Tumors are a classic sign of inflammation, and can be benign or malignant (cancerous). There are dozens of different types of tumors. Their names usually reflect the kind of tissue they arise in, and may also tell you something about their shape or how they grow.

- A tumor is a mass of abnormal tissue. There are two types of breast cancer tumors: those that are non-cancerous, or ‘benign’, and those that are cancerous, which are ‘malignant’. When a tumor is diagnosed as benign, doctors will usually leave it alone rather than remove it.

Brain Tumors Health Library » Nervous System Disorders » Neurological Disorders. A brain tumor is an abnormal growth of tissue in the brain. The tumor can either originate in the brain itself, or come from another part of the body and travel to the brain (metastasize). Brain tumors may be classified as either benign (non-cancerous) or malignant (cancerous), depending on their behavior.

What is a Malignant Tumor? - Definition & Treatment Well, a malignant tumor is a tumor that is invasive, meaning it can invade the surrounding tissues. Malignant tumors contain cells that are cancerous, growing out of control and capable of metastasizing. Metastasize simply means that the cells of the tumor are able to leave the original tumor and travel to other parts of the body. In cancerous tumors or malignant tumors, the cells have lost the ability to stop growing. In other words, they have gone rogue and will not stop dividing. To better explain, nearly every cell in the body is able to grow and divide to make new cells, to a certain extent.

Understanding the Causes, Symptoms, and Treatment of Cancer The organs in our body are made up of cells. Cells divide and multiply as the body needs them. When these cells continue multiplying when the body doesn't need them, the result is a mass or growth, also called a tumor. These growths are considered either benign or malignant.

Cancer: What you need to know Tumors can grow and interfere with the digestive, nervous, and circulatory systems, and they can release hormones that alter body function. Tumors that stay in one spot and demonstrate limited growth are generally considered to be benign. More dangerous, or malignant, tumors form when two things occur:

Pancreatic Tumors A tumor is the uncontrolled cell division in a specific part of the body leading to the formation of lump tissues. It is a growth of tissue that forms an abnormal mass known as neoplasm. There are no useful functions for tumors and they grow at the expense of healthy tissues.

brain tumor A brain tumor is an abnormal growth of tissue in the brain. Unlike other tumors, brain tumors spread by local extension and rarely metastasize (spread) outside the brain. A benign brain tumor is composed of non-cancerous cells and does not metastasize beyond the part of the brain where it originates.A brain tumor is considered malignant if it contains cancer cells, or if it is composed of harmless cells located in an area where it suppresses one or more vital functions.. A brain tumour is any intracranial tumor normally either in the brain itself in the cranial nerves, in the brain envelopes, skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors).

brain tumor A brain tumor is an abnormal growth of tissue in the brain. If the tumor originates in the brain, it is called a primary brain tumor. Primary brain tumors can be benign or malignant. Benign brain tumors. Benign brain tumors are not cancerous.They grow slowly, have distinct borders and rarely spread. Benign tumors can still be dangerous, though. They can damage and compress normal parts of the brain, causing severe dysfunction.enign brain tumors are not cancerous. They grow slowly, have distinct borders and rarely spread.

- Definition. A tumor is an abnormal growth caused by the uncontrolled division of cells. Benign tumors do not have the potential to spread to other parts of the body (a process called metastasis) and are curable by surgical removal.

Benign vs. Malignant: Definition, Characteristics & Differences There are two main classifications of tumors. One is known as benign and the other as malignant. A benign tumor is a tumor that does not invade its surrounding tissue or spread around the body. A malignant tumor is a tumor that may invade its surrounding tissue or spread around the body. I sometimes compare benign tumors to gentle European bees that typically don't bother people or cause them much harm.

Brain Tumors A brain tumor is a growth of abnormal cells in the tissues of the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which start in the brain. Others are metastatic, and they start somewhere else in the body and move to the brain. Brain tumors can cause many symptoms. Some of the most common are.

- Overview. A brain tumor is a collection of abnormal cells in the brain. Brain tumors can be either malignant (cancerous) or benign (unlikely to spread). However, there is a limited amount of space in the skull. Therefore, any brain tumor—even one that is benign—can interfere with the functions of your brain and body.urgery is a common treatment for primary brain tumors. However, not all tumors can be fully removed. In these cases, a surgeon will attempt to reduce the tumor’s size. The extent of removal will depend on the tumor size and location.

What is Cancer? Cancer is a disease in which cells grow and divide with little or no control. There are many different types of cancer. Cancers are typically named for the organ or the cell where the cancer begins. Some cancers can spread from the original site and move to other places in the body. Cells are the basic building blocks of the body.
