One Way to Help Yourself: Learn About Cancer
Words Used When Talking About Cancer What Is Cancer? Cancer: It's Not Contagious
Learning about the type of cancer the person in your family has and the
treatment being used will help you understand what is happening to your family
member. Both of these are important to know about because there are more than
100 different types of cancer, and the treatment for each type is different.
Also, there may be more than one way of treating a type of cancer, so people
who have the same kind of cancer may not even get the same treatment. Treatment
will depend on how old the patient is, whether the cancer has spread to other
places in the body, and what the doctors think is best for each patient.
Treatment will usually follow a protocol (PRO-to-kol), which is a plan for
treating cancer. However, even if two people have the same type of cancer and
the same treatment, the treatment may not work the same way for both of them.
So, if you know or hear of someone who has had the same type of cancer and
treatment as your family member, and that person did not do well, it doesn't
mean that your family member isn't going to get well. It is important to
remember that each person is different and can react to treatment differently.
Benign
(be-NINE): Not cancer.
Biopsy
(BY-op-see): A test where a piece of tissue (a group of cells) is taken from a
person's body and looked at through a microscope to see if the cells are
normal. This is one way to see if a person has cancer. A biopsy also can tell
what type of cancer a person has.
Cancer
(KAN-ser): Over 100 diseases where cells that are not normal grow and divide
rapidly. They crowd out and destroy normal cells the body needs. Cancer can
also spread to other parts of the body.
Diagnosis
(dy-ag-NO-sis): Identifying a disease. A diagnosis is based on tests and
doctors' experience and knowledge.
Hematology
(hee-ma-TOL-o-jee): The study of the blood, the parts of the body where blood
is formed, and blood diseases.
Immune cells:
Cells in the body that protect a person from infection and disease.
Lump:
A thickness or bump under the skin that can be felt by the fingers, either by
the person who has it or by a doctor. Lumps can be a sign of cancer, but most
lumps are not cancerous.
Lymphatic system
(lim-FAT-ik): Certain tissues and organs of the body that make and store cells
that fight infection and disease (immune cells). These cells are carried
throughout the body in an almost colorless fluid called lymph (limf). Lymph and
the vessels that carry lymph fluid also are part of this system.
Malignant
(ma-LIG-nant): Cancer.
Metastasis
(ma-TAS-ta-sis): The spread of cancer from one part of the body to another.
Metastasis also is the word used for a new tumor caused by the spread of cancer
cells.
Oncology
(on-KOL-o-jee): The study and treatment of cancer.
Prognosis
(prog-NO-sis): What might happen to a person who has a disease.
Recurrence
(re-KUR-unce): The return of cancer cells and signs of cancer after a
remission.
Relapse
(REE-laps): Recurrence.
Remission
(ree-MISH-un): The disappearance of cancer symptoms and cells. When this
happens, the disease is said to be "in remission."
Tissue
(TISH-u): A group of cells that performs a specific function.
Tumor (TOO-mur): An abnormal mass of tissue.
Cancer is a group of more than 100 diseases. Each type of cancer has its own
name (such as lung cancer, breast cancer, leukemia), its own treatment, and its
own chances of being cured. Each type of cancer is different from the others in
many ways, but every cancer is the same in this way: Certain cells become
abnormal and grow without control.
The millions of tiny cells that make up the human body are so small that they
can be seen only by looking through a microscope. Although there are different
kinds of cells, such as hair cells, skin cells, and blood cells, each type of
cell makes new cells by dividing into two. This is how worn out, old cells are
replaced with new ones.
What happens when someone has cancer is that a cell changes and doesn't do the
job it should do for the body. When a cancer cell divides, it makes more cells
like itself-cells that are not normal. These cells keep dividing into more
cells. Eventually, they crowd out and destroy the normal, healthy cells and
tissues the body needs.
A group of cells that keeps growing and crowding out normal cells is called a
tumor (TOO-mur). There are two kinds of tumors. A benign (bee-NINE) tumor is
not cancer. The cells of a benign tumor can crowd out healthy cells, but they
cannot spread to other parts of the body. A malignant (ma-LIG-nant) tumor is
cancer. Like a benign tumor, it can crowd out healthy cells around it. Unlike a
benign tumor, however, a malignant tumor also can spread to other parts of the
body. To do this, a cell or group of cells breaks away and moves, usually
through the blood or lymphatic system, to other parts of the body. There they
divide and grow and form tumors made up of cancer cells like the cells they
came from. When this happens, it is called metastasis (me-TAS-ta-sis).
Scientists know that you can't "catch" cancer from someone who has it.
It does not spread like chicken pox or the flu. You can't catch it from being
with a person who has cancer or by drinking from the same glass as that person.
You may know that you can't "catch" cancer, but you may wonder if
having someone in your family who has cancer means that you also are going to
get cancer. Instead of worrying, it is best to talk with your parents and the
doctor about this. They can tell you that cancer usually doesn't run in
families, and you can talk about what scares you.
